PHARMACOLOGY/PHARMACOKINETICS/TOXICOLOGY The analgesic, antipyretic and anti-inflammatory properties of ibruprofen are attributed to COX-1- and COX-2-mediated inhibition of prostaglandin synthesis. Phenylephrine hydrochloride is a selective α1-adrenergic agonist acting at the post synaptic level, causing vasoconstriction within the nasal mucosa to reduce nasal congestion. The pharmacodynamics, pharmacokinetics and toxicology of ibuprofen and phenylephrine hydrochloride are well-established and will not be reviewed further. The individual active ingredients have been in use for many years and there is a wealth of clinical data available. No new preclinical studies have been performed in support of this application and the applicant has provided a literature review. The non-clinical overview was written by an appropriately qualified person and is a thorough review of the pharmacology and toxicology of ibuprofen and phenylephrine hydrochloride. The non-clinical overview focuses on the published pharmacological and toxicological data for the proposed active substances separately with only a brief discussion on the proposed concomitant use. It is noted that, at the time of national grant, this is the first combination of ibuprofen and phenylephrine hydrochloride and that bridging studies addressing pharmacodynamic, pharmacokinetic and toxicological interactions would usually be expected in-line with the Guideline on the Non-clinical Development of Fixed Combinations of Medicinal Products. However, a suitable justification has been provided for the absence of these studies, by arguing that no interactions are anticipated based on differing pharmacological targets, pharmacological actions and metabolic pathways of the active substances. Additionally, neither active has demonstrated any secondary pharmacological effects at the intended dose levels. A clinical point for clarification was raised, requesting any available information on the concomitant use of ibuprofen and phenylephrine. This point has subsequently been resolved on the basis that phenylephrine is similar pharmacologically to pseudoephedrine, which has historically been combined with ibuprofen. EXCIPIENTS The applicant has discussed the safety profiles of the individual excipients in the non-clinical overview. The proposed excipients are well-known and have been in use in pharmaceutical food or preparations for many years. IMPURITIES The non-clinical overview provides a thorough discussion of potential impurities arising from manufacture or degradation of the drug product. The impurity profiles are reported to be within the limits set out in the European Phamacopoeia and do not require toxicological qualification. -9- Lemsip Max/Nurofen All Day/Night Cold and Flu Tablets/Flu Relief Tablets/Flu Relief PL 00063/0541 and 0556 SUMMARY OF PRODUCT CHARACTERISTICS (SPC) The preclinical sections of the SPC are similar to those for already licensed products containing these active substances and are generally acceptable from a non-clinical point of view. ECOTOXICITY/ENVIRONMENTAL RISK ASSESSMENT The applicant has not submitted an environmental risk assessment in-line with the guideline on the environmental risk assessment of medicinal products for human use (EMEA/CHMP/SWP/447/00). Instead, the applicant argues that both active substances are well-established, with many years of sales worldwide and that marketing of this additional presentation will not significantly increase the exposure levels of these active substances to the environment. The justification for the absence of an environmental risk assessment is acceptable. ASSESSOR’S OVERALL CONCLUSIONS The preclinical overview has adequately reviewed relevant published non-clinical data, and discussed the impurity profiles and proposed excipients. In addition, the applicant has justified the lack of bridging studies and an environmental risk assessment. As such, no non-clinical concerns are raised either by the use of ibuprofen and phenylephrine in combination or the proposed formulation. - 10 - Lemsip Max/Nurofen All Day/Night Cold and Flu Tablets/Flu Relief Tablets/Flu Relief PL 00063/0541 and 0556 CLINICAL ASSESSMENT CLINICAL PHARMACOLOGY Pharmacokinetics Ibuprofen In human plasma, ibuprofen is 99% protein-bound onto a single primary site on albumin. Plasma protein binding of ibuprofen may be non-linear. This high degree of binding results in a relatively low volume of distribution. Although ibuprofen is extensively bound to albumin, this does not appear to be a clinically important issue regarding drug interactions. For example, ibuprofen does not significantly displace warfarin from albumin binding sites. Ibuprofen is metabolised by oxidation of the isobutyl group and glucuronidation of the carboxyl moiety. The isobutyl group is hydroxylated both on the tertiary centre, giving 2-(4-(2hydroxy-2-methylpropyl)phenyl)-propionic acid, and also on one of the methyl groups, giving 2-(4-(2-hydroxymethy1-propyl)phenyl)-propionic acid, which is then further oxidized to 2-(4-(carboxypropyl)phenyl)-propionic acid. Both of these metabolites are conjugated with glucuronic acid and all the excretion products, free and conjugates, are pharmacologically inactive. A further route of metabolism involves the formation of the acyl CoA thioester, the essential intermediate in the metabolic chiral inversion from (-)-Rto (+)-S-ibuprofen. The elimination half-life of ibuprofen is relatively short, ranging from 0.9 to 2.5 hours (with a mean of 1.9 hours). Excretion of the metabolites in the urine is usually complete within 24 hours of taking the last dose. Total urinary excretion of ibuprofen and its metabolites is a linear function of dosage. Ibuprofen has a very short half life and, therefore, it is unlikely to influence renal function, except in conditions where renal function is already compromised. Furthermore, accumulation of ibuprofen does not seem to occur during prolonged therapeutic dosing. Phenylephrine Despite its widespread use as a systemically acting decongestant, the pharmacokinetics of phenylephrine is relatively poorly documented. Pre-systemic metabolism (i.e. in the gut) occurs primarily by monoamine oxidase. Absorption is then fairly rapid, with a Tmax of 1-2 hours in aqueous solution. Once within the blood stream, phenylephrine is further metabolised by the liver and its oral bioavailability is estimated to be ~38%. The variability in exposure after oral dosage of aqueous solutions, as indicated by the area under the plasma–drug concentration–time curve (AUC), was about 1.2 fold in a study of four subjects. In another study of 20 subjects, the standard deviation on the AUC was about 20%. Data on the protein binding characteristics of this drug is lacking. Penetration into the central nervous system appears to be minimal and it does not seem to be excreted into breast milk to any significant degree. The volume of distribution of phenylephrine at steady state has been estimated as 184–543 L. Most of an oral dose of phenylephrine is metabolised, with only 2.6% appearing unchanged in the urine after 48 hours. The metabolites of phenylephrine do not contribute to its pharmacological activity. The elimination half-life of phenylephrine is 2-3 hours and the average total clearance has been estimated to be 125.7 litres per hour. A later study reported a number of pharmacokinetic parameters for an orally administered solution of - 11 - Lemsip Max/Nurofen All Day/Night Cold and Flu Tablets/Flu Relief Tablets/Flu Relief PL 00063/0541 and 0556 20mg phenylephrine hydrochloride in combination with 4mg of carbinoxamine. Cmax of phenylephrine in the combination was 432ng/ml, Tmax was 1.0 hour and the elimination half-life was 2.5 hours, agreeing with the earlier study. Despite this relatively low oral availability, clinically the drug is effective as a decongestant via the oral route. The combination of ibuprofen and PE The maximum recommended OTC daily dose of ibuprofen as a single product is 1200mg and the maximum OTC daily dose of phenylephrine hydrochloride is 60mg. The proposed combination tablet containing 200mg ibuprofen and 5mg phenylephrine hydrochloride at an initial dose of 2-tablets every 4 hours with a maximum of 6-tablets in 24 hours, will provide a maximum daily dose of 1200 mg ibuprofen and 30 mg phenylephrine hydrochloride. Assessor’s overall conclusions on pharmaokinetics The metabolic pathways for the two actives are different. Therefore, no pharmacokinetic interactions are anticipated. The applicant has conducted a bioequivalence study (see below) that shows the inclusion of phenylephrine to the formulation does not affect the absorption of ibuprofen. Bioequivalence The following bioequivalence study has been submitted with this application: “A randomised, single-dose, crossover, open-label bioavailability study comparing the rate and extent of absorption of ibuprofen from a fixed combination formulation of 200mg ibuprofen and 5mg phenylephrine hydrochloride (Test product) with the rate and extent of absorption of ibuprofen from standard Nurofen® tablets (Reference product) in normal healthy volunteers”. Subjects received study treatment after a 10-hour overnight fast. Blood samples were taken pre- and up to 720 minutes post dose. The washout period was 3-7 days. The results from the study are presented below: - 12 - Lemsip Max/Nurofen All Day/Night Cold and Flu Tablets/Flu Relief Tablets/Flu Relief PL 00063/0541 and 0556 Assessor’s comment on bioequivalence The study was appropriately designed to establish bioequivalence between the two products. The 90% confidence intervals for Cmax and AUC0-inf were within 80-125%. The rate and extent of absorption of ibuprofen from ibuprofen 200mg plus phenylephrine hydrochloride 5mg fixed combination tablets is equivalent to ibuprofen from ibuprofen 200mg tablets. Therefore the inclusion of phenylephrine in a tablet formulation with ibuprofen does not adversely affect the absorption of ibuprofen. Pharmacodynamics Introduction The active ingredients exert their effects by unrelated pharmacological mechanisms. Ibuprofen is an analgesic and antipyretic at doses indicated for colds and influenza. The analgesic effect is exerted through the inhibition of prostaglandin biosynthesis peripherally, while the antipyretic effect results from central inhibition of prostaglandin biosynthesis. Phenylephrine is an alpha-1-adrenoreceptor agonist, which has a nasal decongestant effect. No pharmacodynamic interactions are expected with these actives and this is based on their different mechanisms of action and intended indications. Assessor’s comment on pharmacodynamics The pharmacodynamic effects of ibuprofen and phenylephrine are well-recognised. Due to their different mechanisms of action, no pharmacodynamic interactions are expected CLINICAL EFFICACY Introduction The common cold and influenza are associated with a number of symptoms. Phenylephrine is used as a nasal decongestant, whereas ibuprofen is used to relieve headache/bodyaches and fever. Hence, the combination is useful in the treatment of different symptoms of cold and flu. This combination of a decongestant and antipyretic/analgesic is a well-established combination therapy. Although no clinical trials have been conducted using the proposed product, bioequivalence studies have demonstrated bioequivalence between Ibuprofen 200 mg tablets and Nurofen 200 mg tablets, and now Nurofen 200 mg and the present combination (i.e. ibuprofen and phenylephrine). The proposed indications for ibuprofen 200mg and phenylephrine hydrochloride 5mg are the same as for those for Nurofen Cold & Flu (ibuprofen and pseudoephedrine). They include the symptomatic relief of mild to moderate pain (such as soft tissue injuries and muscular pain, backache, migraine, neuralgia, headache, sore throat, dental pain and dysmenorrhoea), the symptomatic relief of fever, and the pain and fever of colds/influenza. Ibuprofen Ibuprofen at a dose of 400mg is regularly recommended for the treatment of symptoms of the common cold and influenza. This is exemplified in a study by Winther et al. who reported on the effects of 400 mg ibuprofen or placebo taken three times per day in 80 patients with common cold. The active treatment resulted in a significant reduction in headache (p<0.008), earache (p<0.01), muscle/joint pain (p<0.045) and reduced body temperature (p<0.02). Interestingly there was also a 40% reduction in sneezing (p<0.02) and a 33% reduction in the symptom score for sneezing (p<0.04). - 13 - Lemsip Max/Nurofen All Day/Night Cold and Flu Tablets/Flu Relief Tablets/Flu Relief PL 00063/0541 and 0556 Phenylephrine hydrochloride This is a powerful post synaptic α-receptor agonist. It has a very low cardioselective betareceptor affinity and central stimulant activity is minimal. It is a recognised decongestant, which acts by vasoconstriction to reduce oedema and swelling of the nasal mucosa. By this means, nasal discharge may be reduced, and obstruction associated with colds and influenza may be relieved. The decongestant of choice is pseudoephedrine and this relates to its bioavailability and number of recent trials demonstrating its efficacy for alleviating nasal congestion associated with the common cold. However, due to misuse of pseudoephedrine and the consequent control measures that are now required for this drug, suitable therapeutic alternatives are necessary. There is evidence to suggest that phenylephrine is effective as an oral nasal decongestant. Recently, however, the efficacy of phenylephrine as a nasal decongestant has been called into question and the topic of two reviews with conflicting outcomes. Hatton et al. analysed eight unpublished studies using a random effects model. The primary analysis was focused on administration of a single 10mg dose of phenylephrine hydrochloride. The primary outcome measure was defined as the maximum reduction in nasal airway resistance (NAR) over 120 minutes, expressed as the percent decrease from baseline. This was measured by determining the mean change from baseline for both phenylephrine hydrochloride and placebo. The main finding was that 10mg of phenylephrine hydrochloride did not affect NAR as it was no different from placebo. Indeed, the mean maximal difference between phenylephrine hydrochloride and placebo was 10.1% (95% CI from ~0.8 to 23.9%). However, at a dose of 25mg, Hatton et al. did report a significant reduction of maximal NAR (-27.6%; 95% CI from 17.5 to 37.7%). This was followed by another review by Kollar et al. They reviewed the same population of studies and incorporated both a random effects (like Hatton et al.) and fixed-effects statistical model. In contrast, however, statistical significance was determined at 30 and 60 minutes after dosing (these were defined as the primary time-points) and, like Hatton et al., a change in NAR from baseline was the efficacy variable. Results showed that 10 mg of phenylephrine hydrochloride was significantly (P<0.05) more effective than placebo at the primary time-points (both 30 minutes and 60 minutes) and even at 90 minutes in both fixed- and random-effects models. Furthermore, using the fixed-effects model, 10mg of phenylephrine hydrochloride was also significantly more effective than placebo at 120 and 180 minutes after dosing (P<0.05). When compared with placebo, NAR was decreased by 6% after 30 and 45 minutes; -16.6% after 60 minutes; and, less than -20% after 60 and 180 minutes. Thus, Kollar et al. concluded that single oral doses of 10 mg of phenylephrine hydrochloride were effective against the acute nasal congestion associated with common colds in adults. The combination of ibuprofen and phenylephrine hydrochloride The above sections indicate that ibuprofen targets the pain associated with a common cold and that phenylephrine hydrochloride targets nasal congestion. Hence, both actives work in synergy to alleviate the symptoms of a common cold and flu. - 14 - Lemsip Max/Nurofen All Day/Night Cold and Flu Tablets/Flu Relief Tablets/Flu Relief PL 00063/0541 and 0556 The dose of phenylephrine hydrochloride used to relieve nasal congestion ranges between 5 and 20mg, with the frequency ranging between three and four times daily. The efficacious dose in adults (based on the findings of Kollar et al.) is 10mg of phenylephrine hydrochloride. In Nurofen for Cold & Flu, each tablet provides 5mg of phenylephrine hydrochloride, so two tablets are required to reach the efficacious level of 10mg of phenylephrine hydrochloride. These two tablets are then taken every 4 hours in order to alleviate nasal congestion. This equates to a maximum daily dose of 30.0mg and this is within the accepted dosage range for phenylephrine hydrochloride stipulated for a pharmacy product (i.e. 40mg) and by the FDA (60mg). Although no ibuprofen/phenylephrine hydrochloride combination product was available at the time of assessment, both have been in widespread use as non-prescription ingredients for many years. However, unlike ibuprofen, there are not many phenylephrine hydrochloride products on the market. Countries such as the UK, Australia and the US are adopting a modified approach to the registration of products containing phenylephrine hydrochloride in place of pseudoephedrine hydrochloride. This approach is justified by the pharmacological similarity between pseudoephedrine hydrochloride and phenylephrine hydrochloride. In view of the above, the marketing authorisation holder has provided data from studies performed comparing ibuprofen/pseudoephedrine combination versus other products, including ibuprofen and pseudoephedrine on their own. A summary of these studies is provided below: Assessor’s comment on clinical efficacy Ibuprofen and phenylephrine hydrochloride have been in clinical use for many years. The efficacy of ibuprofen in the proposed indications is well-recognised. The efficacy of phenylephrine is more controversial. Despite the fact that there appears to be evidence from - 15 - Lemsip Max/Nurofen All Day/Night Cold and Flu Tablets/Flu Relief Tablets/Flu Relief PL 00063/0541 and 0556 published literature on the anti-congestant effect of phenylephrine, this is not undisputable. In spite of this, the pharmacological similarity between pseudoephedrine and phenylephrine means that a substitution of pseudoephedrine for phenylephrine is accepted as reasonable. This is further supported by the clinical trial data provided by the marketing authorisation holder, comparing ibuprofen/pseudoephedrine combinations with these products administered individually. CLINICAL SAFETY No new safety data have been provided. The clinical expert provides an overview of the safety profile of the two active ingredients. The adverse events associated with use of NSAIDS and phenylephrine are well-recognised. Safety in special populations Of special interest is use during pregnancy. Ibuprofen, in the last trimester of pregnancy, can inhibit uterine contractions and cause the premature closure of the ductus arteriosus; pulmonary hypertension in the neonate; increased bleeding tendency of mother and infant; and increase in the incidence of oedema in the mother. Thus, the SPC indicates that the use of Nurofen during the first 6 months of pregnancy should be avoided and it should not be used during the last trimester of pregnancy as the onset of labour may be reduced and the duration of labour extended. Assessor’s comment on clinical safety The safety profile of ibuprofen and phenylephrine is well-recognised. No new safety concerns are anticipated with use of the two actives in a combination product. EXPERT REPORTS A Clinical Expert Report has been written by an appropriately qualified physician. It is an adequate summary of the clinical aspects of the dossier. PRODUCT LITERATURE Summary of Product Characteristics (SPC) The SPCs are clinically satisfactory. Patient Information Leaflet (PIL) The PILs are clinically satisfactory. Labelling The labelling is clinically satisfactory. OVERALL CONCLUSION At the time of assessing these applications, the combination of ibuprofen and phenylephrine hydrochloride had never been marketed before. The marketing authorisation holder has adequately presented information for phenylephrine and, where applicable, for pseudoephedrine, such that grant of marketing authorisations are recommended for these products. - 16 - Lemsip Max/Nurofen All Day/Night Cold and Flu Tablets/Flu Relief Tablets/Flu Relief PL 00063/0541 and 0556 OVERALL CONCLUSION AND RISK BENEFIT ASSESSMENT QUALITY The important quality characteristics of Lemsip Max All Day Cold and Flu Tablets, Lemsip Max All Day Flu Relief Tablets, Lemsip Max All Day Flu Relief, Nurofen All Day Cold and Flu Tablets, Nurofen All Day Flu Relief Tablets and Nurofen All Day Flu Relief, Lemsip Max All Night Cold and Flu Tablets, Lemsip Max All Night Flu Relief Tablets, Lemsip Max All Night Flu Relief, Nurofen All Night Cold and Flu Tablets, Nurofen All Night Flu Relief Tablets and Nurofen All Night Flu Relief are well-defined and controlled.

RISK BENEFIT ASSESSMENT The quality of the products is acceptable and no new preclinical or clinical safety concerns have been identified. Extensive clinical experience with both ibuprofen and phenylephrine/pseudoephedrine is considered to have demonstrated the therapeutic value of the compound. The risk benefit is, therefore, considered to be positive. - 17 - Lemsip Max/Nurofen All Day/Night Cold and Flu Tablets/Flu Relief Tablets/Flu Relief PL 00063/0541 and 0556 LEMSIP MAX ALL DAY COLD AND FLU TABLETS LEMSIP MAX ALL DAY FLU RELIEF TABLETS LEMSIP MAX ALL DAY FLU RELIEF NUROFEN ALL DAY COLD AND FLU TABLETS NUROFEN ALL DAY FLU RELIEF TABLETS NUROFEN ALL DAY FLU RELIEF LEMSIP MAX ALL NIGHT COLD AND FLU TABLETS LEMSIP MAX ALL NIGHT FLU RELIEF TABLETS LEMSIP MAX ALL NIGHT FLU RELIEF NUROFEN ALL NIGHT COLD AND FLU TABLETS NUROFEN ALL NIGHT FLU RELIEF TABLETS NUROFEN ALL NIGHT FLU RELIEF STEPS TAKEN FOR ASSESMENT 1 The MHRA received the marketing authorisation applications on 19/03/2008. 2 Following standard checks and communication with the applicant the MHRA considered the application valid on 27/03/2008. 3 Following assessment of the application the MHRA requested further information relating to the pharmaceutical dossier on 25/06/2008, relating to the preclinical dossier on 25/09/2008, and further information relating to the clinical dossier on 16/07/2008. 4 The applicant responded to the MHRA’s requests, providing further information relating to the pharmaceutical and clinical dossiers on 09/09/2008, and relating to the preclinical dossier on 29/10/2008. 5 The applications were determined on 17/11/2008 - 18 - Lemsip Max/Nurofen All Day/Night Cold and Flu Tablets/Flu Relief Tablets/Flu Relief PL 00063/0541 and 0556 LEMSIP MAX ALL DAY COLD AND FLU TABLETS LEMSIP MAX ALL DAY FLU RELIEF TABLETS LEMSIP MAX ALL DAY FLU RELIEF NUROFEN ALL DAY COLD AND FLU TABLETS NUROFEN ALL DAY FLU RELIEF TABLETS NUROFEN ALL DAY FLU RELIEF LEMSIP MAX ALL NIGHT COLD AND FLU TABLETS LEMSIP MAX ALL NIGHT FLU RELIEF TABLETS LEMSIP MAX ALL NIGHT FLU RELIEF NUROFEN ALL NIGHT COLD AND FLU TABLETS NUROFEN ALL NIGHT FLU RELIEF TABLETS NUROFEN ALL NIGHT FLU RELIEF STEPS TAKEN AFTER ASSESSMENT Date submitted Application Scope type Outcome - 19 - Lemsip Max/Nurofen All Day/Night Cold and Flu Tablets/Flu Relief Tablets/Flu Relief PL 00063/0541 and 0556 LEMSIP MAX ALL DAY COLD AND FLU TABLETS LEMSIP MAX ALL DAY FLU RELIEF TABLETS LEMSIP MAX ALL DAY FLU RELIEF NUROFEN ALL DAY COLD AND FLU TABLETS NUROFEN ALL DAY FLU RELIEF TABLETS NUROFEN ALL DAY FLU RELIEF LEMSIP MAX ALL NIGHT COLD AND FLU TABLETS LEMSIP MAX ALL NIGHT FLU RELIEF TABLETS LEMSIP MAX ALL NIGHT FLU RELIEF NUROFEN ALL NIGHT COLD AND FLU TABLETS NUROFEN ALL NIGHT FLU RELIEF TABLETS NUROFEN ALL NIGHT FLU RELIEF SUMMARY OF PRODUCT CHARACTERISTICS 1 NAME OF THE MEDICINAL PRODUCT Lemsip Max All Day Cold & Flu Tablets, or Lemsip Max All Day Flu Relief Tablets, or Lemsip Max All Day Flu Relief, or Nurofen All Day Cold & Flu Tablets or Nurofen All Day Flu Relief Tablets, or Nurofen All Day Flu Relief. 2 QUALITATIVE AND QUANTITATIVE COMPOSITION Active Ingredients Quantity Ibuprofen BP 200.0mg Phenylephrine hydrochloride 5.0mg For full list of excipients, see Section 6.1. 3 PHARMACEUTICAL FORM Yellow film coated tablet, printed with an identifying motif (IPE) in black ink. 4 4.1 CLINICAL PARTICULARS Therapeutic indications For the relief of symptoms of cold and 'flu with associated congestion, including aches and pains, headache, fever, sore throat, blocked nose and sinuses. 4.2 Posology and method of administration For oral administration and short-term use only. Adults, the elderly and children over 12 years: The lowest effective dose should be used for the shortest duration necessary to relieve symptoms. The patient should consult a doctor if symptoms persist or worsen, or if the product is required for more than 10 days. Two tablets every 8 hours. Leave at least 4 hours between doses and do not exceed six tablets in any 24 hour period. Not to be given to children under 12 years. 4.3 Contraindications Hypersensitivity to ibuprofen, phenylephrine or any of the excipients in the product. Hypertension and severe coronary heart disease. - 20 - Lemsip Max/Nurofen All Day/Night Cold and Flu Tablets/Flu Relief Tablets/Flu Relief PL 00063/0541 and 0556 Patients who have previously shown hypersensitivity reactions (e.g. asthma, rhinitis, angioedema or urticaria) in response to aspirin or other non-steroidal anti-inflammatory drugs (NSAIDs). Active or history of recurrent peptic ulcer/haemorrhage (two or more distinct episodes or proven ulceration or bleeding). History of gastrointestinal bleeding or perforation, related to previous NSAIDs therapy. Severe heart failure, renal failure or hepatic failure (see Section 4.4). Last trimester of pregnancy. Use with concomitant NSAIDs including cyclo-oxygenase-2 specific inhibitors (see Section 4.5). 4.4 Special warnings and precautions for use Ibuprofen Undesirable effects may be minimised by using the lowest effective dose for the shortest duration necessary to control symptoms (see gastrointestinal and cardiovascular risks below). The elderly are at increased risk of consequence of adverse reactions to NSAIDs, especially gastrointestinal bleeding and perforation which may be fatal. Respiratory: Bronchospasm may be precipitated in patients suffering from or with a previous history of bronchial asthma or allergic disease. Other NSAIDs: The use of this product with concomitant NSAIDs, including cyclo-oxygenase-2 selective inhibitors, should be avoided (see Section 4.5). SLE and mixed connective tissue disease: Systemic lupus erythematosus and mixed connective tissue disease - increased risk of aseptic meningitis (see Section 4.8). Renal: Renal impairment as renal function may further deteriorate (see Sections 4.3 and 4.8). Hepatic: Hepatic dysfunction (see Sections 4.3 and 4.8). Cardiovascular and cerebrovascular effects: Caution (discussion with doctor or pharmacist) is required prior to starting treatment in patients with a history of hypertension and/or heart failure as fluid retention, hypertension and oedema have been reported in association with NSAID therapy. Clinical trial and epidemiological data suggest that use of ibuprofen, particularly at high doses (2400 mg daily) and in long-term treatment, may be associated with a small increased risk of arterial thrombotic events (for example, myocardial infarction or stroke). Overall, epidemiological studies do not suggest that low dose ibuprofen (≤1200 mg daily) is associated with an increased risk of myocardial infarction. Impaired female fertility: There is limited evidence that drugs which inhibit cyclooxygenase/prostaglandin synthesis may cause impairment of female fertility by an effect on ovulation. This is reversible on withdrawal of treatment. Gastrointestinal: NSAIDs should be given with care to patients with a history of gastrointestinal disease (ulcerative colitis, Crohn's disease) as these conditions may be exacerbated (see Section 4.8). GI bleeding, ulceration or perforation, which can be fatal, has been reported with all NSAIDs at any time during treatment, with or without warning symptoms or a previous history of serious GI events. The risk of GI bleeding, ulceration or perforation is higher with increasing NSAID doses, in patients with a history of ulcer, particularly if complicated with haemorrhage or perforation (see Section 4.3), and in the elderly. These patients should commence treatment on the lowest dose available. - 21 - Lemsip Max/Nurofen All Day/Night Cold and Flu Tablets/Flu Relief Tablets/Flu Relief PL 00063/0541 and 0556 Patients with a history of GI toxicity, particularly the elderly, should report any unusual abdominal symptoms (especially GI bleeding), particularly in the initial stages of treatment. Caution should be advised in patients receiving concomitant medications which could increase the risk of ulceration or bleeding, such as oral corticosteroids, anticoagulants such as warfarin, selective serotonin-reuptake inhibitors or anti-platelets agents such as aspirin (see Section 4.5). When GI bleeding or ulceration occurs in patients receiving ibuprofen, the treatment should be withdrawn. Dermatological: Serious skin reactions, some of them fatal, including exfoliating dermatitis, Stevens-Johnson Syndrome, and toxic epidermal necrolysis, have been reported very rarely in association with the use of NSAIDs (see Section 4.8). Patients appear to be at highest risk of these reactions early in the course of therapy: the onset of the reaction occurring in the majority of cases within the first month of treatment. This product should be discontinued at the first appearance of skin rash, mucosal lesions or any other sign of hypersensitivity. The label will include: Read the enclosed leaflet before taking this product. Do not take if you: • Have (or have had two or more episodes of) a stomach ulcer, perforation or bleeding. • Are allergic to ibuprofen or any other ingredient of the product, aspirin or other related painkillers. • Are taking other NSAID painkillers, or aspirin with a daily dose above 75 mg. Speak to a pharmacist or your doctor before taking if you: • Have or have had asthma, diabetes, high cholesterol, high blood pressure, a stroke, heart, liver, kidney or bowel problems. • Are a smoker. • Are pregnant. If symptoms persist or worsen, consult your doctor. Phenylephrine Phenylephrine should be used with care in patients with hyperthyroidism, cardiovascular disease, diabetes mellitus, closed angle glaucoma, prostatic enlargement and hypertension. 4.5 Interaction with other medicinal products and other forms of interaction Ibuprofen Ibuprofen should not be used in combination with: Aspirin: Unless low-dose aspirin (not above 75 mg daily) has been advised by a doctor, as this may increase the risk of adverse reactions (see Section 4.4). Other NSAIDs including cyclo-oxygenase-2 selective inhibitors: Avoid concomitant use of two or more NSAIDs as this may increase the risk of adverse reactions (see Section 4.4). Ibuprofen should be used with caution in combination with: Anti-coagulants: NSAIDs may enhance the effects of anticoagulants such as warfarin (see Section 4.4). Antihypertensives and diuretics: NSAIDs may diminish the effect of these drugs. Diuretics can increase the risk of nephrotoxicity. Corticosteroids: Increased risk of gastrointestinal ulceration or bleeding (see Section 4.4). Anti-platelet agents and selective serotonin-reuptake inhibitors (SSRIs): Increased risk of gastrointestinal bleeding (see Section 4.4). - 22 - Lemsip Max/Nurofen All Day/Night Cold and Flu Tablets/Flu Relief Tablets/Flu Relief PL 00063/0541 and 0556 Cardiac glycosides: NSAIDs may exacerbate cardiac failure, reduce GFR and increase plasma glycoside levels. Lithium: There is evidence for potential increase in plasma levels of lithium. Methotrexate: There is potential for an increase in plasma methotrexate. Ciclosporin: Increased risk of nephrotoxicity. Mifepristone: NSAIDs should not be used for 8-12 days after mifepristone administration as NSAIDs can reduce the effect of mifepristone. Tacrolimus: Possible increased risk of nephrotoxicity when NSAIDs are given with tacrolimus. Zidovudine: Increased risk of haematological toxicity when NSAIDs are given with zidovudine. There is evidence of an increased risk of haemarthroses and haematoma in HIV(+) haemophiliacs receiving concurrent treatment with zidovudine and ibuprofen. Quinolone antibiotics: Animal data indicate that NSAIDs can increase the risk of convulsions associated with quinolone antibiotics. Patients taking NSAIDs and quinolones may have an increased risk of developing convulsions. Phenylephrine Phenylephrine may adversely interact with other sympathomimetics, vasodilators and beta-blockers. Phenylephrine is not recommended for patients currently receiving or within two weeks of stopping therapy with monoamine oxidase inhibitors (MAOIs). 4.6 Pregnancy and lactation Ibuprofen Whilst no teratogenic effects have been demonstrated to in animal experiments, the use of this product should, if possible, be avoided during the first six months of pregnancy. During the third trimester, ibuprofen is contraindicated as there is a risk of premature closure of the fetal ductus arteriosus with possible persistent pulmonary hypertension. The onset of labour may be delayed and the duration increased with an increased bleeding tendency in both mother and child (see Section 4.3). In limited studies, ibuprofen appears in the breast milk in very low concentrations and is unlikely to affect the breast-fed infant adversely. See Section 4.4 regarding female fertility. Phenylephrine Due to the vasoconstrictive properties of phenylephrine, the product should be used in caution in patients with a history of pre-eclampsia. Phenylephrine may reduce placental perfusion and the product should be used in pregnancy only if the benefits outweigh this risk. There is no information on use of phenylephrine in lactation. 4.7 Effects on ability to drive and use machines No adverse effects known. - 23 - Lemsip Max/Nurofen All Day/Night Cold and Flu Tablets/Flu Relief Tablets/Flu Relief PL 00063/0541 and 0556 4.8 Undesirable effects Ibuprofen Hypersensitivity reactions have been reported following treatment with ibuprofen and these may consist of: (a) Non-specific allergic reaction and anaphylaxis. (b) Respiratory tract reactivity, e.g. asthma, aggravated asthma, bronchospasm or dyspnoea. (c) Various skin reactions, e.g. pruritis, urticaria, angioedema and, more rarely, exfoliative and bullous dermatoses (including epidermal necrolysis and erythema multiforme). The following list of adverse effects relates to those experienced with ibuprofen at OTC doses, for short-term use. In the treatment of chronic conditions, under long-term treatment, additional effects may occur. Hypersensitivity reactions Uncommon: Hypersensitivity reactions with urticaria and pruritus. Very rare: Severe hypersensitivity reactions. Symptoms could be: facial, tongue and laryngeal swelling, dyspnoea, tachycardia, hypotension (anaphylaxis, angioedema or severe shock). Exacerbation of asthma and bronchospasm. Gastrointestinal The most commonly-observed adverse events are gastrointestinal in nature. Uncommon: Abdominal pain, nausea and dyspepsia. Rare: Diarrhoea, flatulence, constipation and vomiting. Very rare: Peptic ulcer, perforation and gastrointestinal haemorrhage, melaena, haematemesis, sometimes fatal, particularly in the elderly. Ulcerative stomatitis, gastritis and mouth ulceration. Exacerbation of colitis and Crohn's disease (see Section 4.4). Nervous System Uncommon: Headache, dizziness and tinnitus. Very rare: Aseptic meningitis - single cases have been reported very rarely. Renal Very rare: Acute renal failure, papillary necrosis, especially in long-term use, associated with increased serum urea and oedema. Hepatic Very rare: Liver disorders. Haematological Very rare: Haematopoietic disorders (anaemia, leucopenia, thrombocytopenia, pancytopenia, agranulocytosis). First signs are: fever, sore throat, superficial mouth ulcers, flu-like symptoms, severe exhaustion, unexplained bleeding and bruising. Dermatological Uncommon: Various skin rashes. Very rare: Severe forms of skin reactions such as bullous reactions, including Stevens-Johnson Syndrome, erythema multiforme and toxic epidermal necrolysis, can occur. Immune System In patients with existing auto-immune disorders (such as systemic lupus erythematosus, mixed connective tissue disease) during treatment with ibuprofen, single cases of symptoms of aseptic meningitis, such as stiff neck, headache, nausea, vomiting, fever or disorientation, have been observed (see Section 4.4). Cardiovascular and Cerebrovascular Oedema, hypertension and cardiac failure have been reported in association with NSAID treatment. - 24 - Lemsip Max/Nurofen All Day/Night Cold and Flu Tablets/Flu Relief Tablets/Flu Relief PL 00063/0541 and 0556 Clinical trial and epidemiological data suggest that use of ibuprofen, particularly at high doses (2400 mg daily) and in long-term treatment, may be associated with a small increased risk of arterial thrombotic events (for example, myocardial infarction or stroke) (see Section 4.4). Phenylephrine High blood pressure with headache, vomiting and rarely, palpitations. Also, rare reports of allergic reactions. 4.9 Overdose Ibuprofen In children, ingestion of more than 400 mg/kg may cause symptoms. In adults, the dose response rate effect is less clear cut. The half-life in overdose is 1.5-3 hours. Symptoms Patients who have ingested clinically important amounts of NSAIDs will develop no more than nausea, vomiting, epigastric pain, or more rarely diarrhoea. Tinnitus, headache and gastrointestinal bleeding are also possible. In more serious poisoning, toxicity is seen in the central nervous system, manifesting as drowsiness, occasionally excitation and disorientation or coma. Occasionally patients develop convulsions. In serious poisoning metabolic acidosis may occur and prothrombin time/INR may be prolonged, probably due to interference with the actions of circulating clotting factors. Acute renal failure and liver damage may occur. Exacerbation of asthma is possible in asthmatics. Management Management should be symptomatic and supportive and include the maintenance of a clear airway and monitoring of cardiac and vital signs until stable. Consider oral administration of activated charcoal if the patient presents within 1 hour of ingestion of a potentially toxic amount. If frequent or prolonged, convulsions should be treated with intravenous diazepam or lorazepam. Give bronchodilators for asthma. Phenylephrine Features of severe overdosage of phenylephrine include haemodynamic changes and cardiovascular collapse with respiratory depression. Treatment includes early gastric lavage and symptomatic and supportive measures. Hypertensive effects may be treated with an intravenous alpha-receptor blocking agent. 5 5.1 PHARMACOLOGICAL PROPERTIES Pharmacodynamic properties M01AE51 - Ibuprofen, combinations. Ibuprofen Ibuprofen is a propionic acid derivative NSAID that has demonstrated its efficacy by inhibition of prostaglandin synthesis. In humans ibuprofen reduces inflammatory pain, swellings and fever. Furthermore, ibuprofen reversibly inhibits platelet aggregation. The therapeutic effect of ibuprofen in symptoms relating to the common cold and influenza has a duration of up to 8 hours. Phenylephrine Phenylephrine is a post-synaptic alpha-receptor agonist with low cardioselective beta-receptor affinity and minimal central stimulant activity. It is a recognised decongestant and acts by vasoconstriction to reduce oedema and nasal swelling. - 25 - Lemsip Max/Nurofen All Day/Night Cold and Flu Tablets/Flu Relief Tablets/Flu Relief PL 00063/0541 and 0556 5.2 Pharmacokinetic properties Ibuprofen Ibuprofen is rapidly absorbed following administration and is rapidly distributed throughout the whole body. The excretion is rapid and complete via the kidneys. Maximum plasma concentrations are reached 45 minutes after ingestion if taken on an empty stomach. When taken with food, peak levels are observed after 1-2 hours. These times may vary with different dosage forms. The half-life of ibuprofen is about 2 hours. In limited studies, ibuprofen appears in the breast milk in very low concentr-ations. Phenylephrine Phenylephrine is absorbed from the gastrointestinal tract, but has reduced bioavailability by the oral route due to first-pass metabolism. It retains activity as a nasal decongestant when given orally, the drug distributing through the systemic circulation to the vascular bed of the nasal mucosa. When taken by mouth as a nasal decongestant, phenylephrine is usually given at intervals of 4-6 hours. Ibuprofen and Phenylephrine Combination The ibuprofen component of this fixed combination (ibuprofen 200 mg plus phenylephrine hydrochloride 5 mg) is absorbed faster than standard ibuprofen 200 mg tablets, with therapeutic levels being reached in 26.4 minutes (from the fixed combination) as opposed to 55.2 minutes (for standard ibuprofen). 5.3 Preclinical safety data There are no findings of relevance to the prescriber other than those already mentioned elsewhere in the SPC. 6 6.1 PHARMACEUTICAL PARTICULARS List of excipients Microcrystalline cellulose Sodium starch glycolate Type A Hypromellose Magnesium stearate Talc Water, purified Industrial methylated spirits Mastercote yellow FA 0156 Black printing ink 6.2 Incompatibilities Not applicable. 6.3 Shelf life Two years. 6.4 Special precautions for storage Store in a dry place.

Symptoms Patients who have ingested clinically important amounts of NSAIDs will develop no more than nausea, vomiting, epigastric pain, or more rarely diarrhoea. Tinnitus, headache and gastrointestinal bleeding are also possible. In more serious poisoning, toxicity is seen in the central nervous system, manifesting as drowsiness, occasionally excitation and disorientation or coma. Occasionally patients develop convulsions. In serious poisoning metabolic acidosis may occur and prothrombin time/INR may be prolonged, probably due to interference with the actions of circulating clotting factors. Acute renal failure and liver damage may occur. Exacerbation of asthma is possible in asthmatics. - 32 - Lemsip Max/Nurofen All Day/Night Cold and Flu Tablets/Flu Relief Tablets/Flu Relief PL 00063/0541 and 0556 Management Management should be symptomatic and supportive and include the maintenance of a clear airway and monitoring of cardiac and vital signs until stable. Consider oral administration of activated charcoal if the patient presents within 1 hour of ingestion of a potentially toxic amount. If frequent or prolonged, convulsions should be treated with intravenous diazepam or lorazepam. Give bronchodilators for asthma. Phenylephrine Features of severe overdosage of phenylephrine include haemodynamic changes and cardiovascular collapse with respiratory depression. Treatment includes early gastric lavage and symptomatic and supportive measures. Hypertensive effects may be treated with an intravenous alpha-receptor blocking agent. 5 5.1 PHARMACOLOGICAL PROPERTIES Pharmacodynamic properties M01AE51 - Ibuprofen, combinations. Ibuprofen Ibuprofen is a propionic acid derivative NSAID that has demonstrated its efficacy by inhibition of prostaglandin synthesis. In humans ibuprofen reduces inflammatory pain, swellings and fever. Furthermore, ibuprofen reversibly inhibits platelet aggregation. The therapeutic effect of ibuprofen in symptoms relating to the common cold and influenza has a duration of up to 8 hours. Phenylephrine Phenylephrine is a post-synaptic alpha-receptor agonist with low cardioselective beta-receptor affinity and minimal central stimulant activity. It is a recognised decongestant and acts by vasoconstriction to reduce oedema and nasal swelling. 5.2 Pharmacokinetic properties Ibuprofen Ibuprofen is rapidly absorbed following administration and is rapidly distributed throughout the whole body. The excretion is rapid and complete via the kidneys. Maximum plasma concentrations are reached 45 minutes after ingestion if taken on an empty stomach. When taken with food, peak levels are observed after 1-2 hours. These times may vary with different dosage forms. The half-life of ibuprofen is about 2 hours. In limited studies, ibuprofen appears in the breast milk in very low concentr-ations. Phenylephrine Phenylephrine is absorbed from the gastrointestinal tract, but has reduced bioavailability by the oral route due to first-pass metabolism. It retains activity as a nasal decongestant when given orally, the drug distributing through the systemic circulation to the vascular bed of the nasal mucosa. When taken by mouth as a nasal decongestant, phenylephrine is usually given at intervals of 4-6 hours. Ibuprofen and Phenylephrine Combination The ibuprofen component of this fixed combination (ibuprofen 200 mg plus phenylephrine hydrochloride 5 mg) is absorbed faster than standard ibuprofen 200 mg tablets, with therapeutic - 33 - Lemsip Max/Nurofen All Day/Night Cold and Flu Tablets/Flu Relief Tablets/Flu Relief PL 00063/0541 and 0556 levels being reached in 26.4 minutes (from the fixed combination) as opposed to 55.2 minutes (for standard ibuprofen). 5.3 Preclinical safety data There are no findings of relevance to the prescriber other than those already mentioned elsewhere in the SPC. 6 6.1 PHARMACEUTICAL PARTICULARS List of excipients Microcrystalline cellulose Sodium starch glycolate Type A Hypromellose Magnesium stearate Talc Water, purified Industrial methylated spirits Mastercote yellow FA 0156 Black printing ink 6.2 Incompatibilities Not applicable. 6.3 Shelf life Two years. 6.4 Special precautions for storage Store in a dry place.
