ATV should not be used in patients with moderate to severe hepatic impairment3 1. Lapadula G, et al. EACS 2007, Poster 9.6/03; 2. Lankisch TO, et al.

INDICATIONS: Antiretroviral combination treatment of HIV1 infected adults, adolescents or children over 6 years. DOSAGE: Oral. Administer once or twice daily at least 2 hours before or after a meal with 100ml of water. Adults: Recommended daily dose: 400mg for patients weighing 60kg and 250mg for patients weighing <60kg. Children (over 6 years): recommended daily dose based on body surface area is 240mg/m2 (180mg/m2 in combination with zidovudine). Dose adjustment required for patients with renal impairment. Refer to SPC for full details. CONTRAINDICATIONS: Hypersensitivity to contents. Children younger than 6 years. SPECIAL WARNINGS AND PRECAUTIONS: Not for sole use. Extreme caution in patients with history of pancreatitis. Where possible suspend dosing until a diagnosis of pancreatitis has been excluded and when treatment with other drugs known to cause pancreatic toxicity is required, suspend didanosine wherever possible. Dose suspension should be considered when biochemical markers of pancreatitis have increased, even in the absence of symptoms. Patients on didanosine may develop toxic peripheral neuropathy. Suspend Videx EC until resolution of symptoms. A reduced dose may then be tolerated. Liver failure has occurred rarely. Observe for liver enzyme elevations and suspend treatment if enzymes rise >5 times above the upper limit of normal. Re-challenge only if the potential benefits clearly outweigh the potential risks. Lactic acidosis has been reported with the use of nucleoside analogues. Retinal or optic nerve changes may occur rarely. Children should have a retinal examination every 6 months or if a change in vision occurs. Given lipodystrophy association with combination antiretroviral therapy, consider monitoring fasting serum lipids and blood glucose and manage as appropriate. Nucleoside and nucleotide analogues have been reported to cause mitochondrial dysfunction in HIV-negative infants exposed in-utero and/or post-natally. DRUG INTERACTIONS: Co-administration with drugs known to cause peripheral neuropathy or pancreatitis may increase the risk of these toxicities. Co-administration of didanosine and tenofovir disoproxil fumarate results in a 4060% increase in systemic exposure to didanosine and is therefore not recommended. Co-administration of didanosine with xanthine oxidase inhibitors, such as allopurinol, may result in increased systemic exposure to didanosine, therefore patients should be carefully monitored for didanosine-related adverse events. PREGNANCY & LACTATION: Avoid use in pregnancy and lactation. Use only when the potential benefit outweighs the possible risk. UNDESIRABLE EFFECTS: Common: Pancreatitis, peripheral neurologic symptoms, lipodystrophy and metabolic abnormalities, diarrhoea, nausea, vomiting, abdominal pain, rash, fatigue, allergic reactions, asthenia, headache, neutropenia. Increased uric acid, liver enzymes, bilirubin level. Rarely reported events post marketing are: chills and fever, flatulence, parotid gland enlargement, dry mouth, lactic acidosis, anorexia, diabetes mellitus, hypoglycaemia, hyperglycaemia, alopecia, hepatitis, liver failure, hepatic steatosis, sialoadenitis, anaemia, leukopenia, thrombocytopenia, anaphylactic reaction, dry eyes, retinal depigmentation, optic neuritis, myalgia, rhabdomyolysis.

Adverse events should also be reported to Bristol-Myers Squibb Pharmaceuticals Ltd Medical Information on 0800 731 1736, [email protected] ATRIPLA PRESCRIBING INFORMATION ATRIPLA® PRESCRIBING INFORMATION Presentation: Atripla film-coated tablet. Each tablet contains 600mg of efavirenz, 200mg of emtricitabine and 245mg of tenofovir disoproxil (as fumarate). Indications: For treatment of HIV-1 infected adults with virologic suppression to HIV-1 RNA levels of <50 copies/ml on their current combination therapy for more than 3 months. Patients must not have experienced virological failure on prior antiretroviral therapy and must not have resistance to any of the three components of Atripla. Dosage & Administration: Therapy should be initiated by a physician experienced in the management of HIV infection. Adults: One tablet once daily taken orally on an empty stomach at bedtime. Children and adolescents: not recommended. Elderly: Insufficient data are available on which to make dose recommendations for patients over the age of 65 years – caution should be exercised. Not recommended in patients with moderate or severe renal impairment (CrCl <50ml/min). No dose modification necessary in patients with mild to moderate liver disease. Contraindications: Hypersensitivity to efavirenz, emtricitabine, tenofovir, tenofovir disoproxil fumarate, or any of the excipients. Atripla must not be used in patients with severe hepatic impairment. It must not be administered concurrently with terfenadine, astemizole, cisapride, midazolam, triazolam, pimozide, bepridil or ergot alkaloids, because competition for CYP3A4 by efavirenz could result in inhibition of metabolism and create the potential for serious and/or life-threatening undesirable effects (e.g. cardiac arrhythmias, prolonged sedation or respiratory depression). Herbal preparations containing St. John’s wort must not be used while taking Atripla due to the risk of decreased plasma concentrations and reduced clinical effects of efavirenz. Atripla must not be administered concurrently with voriconazole because efavirenz significantly decreases voriconazole plasma concentrations, while voriconazole significantly increases efavirenz plasma concentrations. Warnings and Precautions: Atripla should not be administered concomitantly with other medicinal products containing any of the same active components, with other cytidine analogues such as lamivudine or with adefovir dipivoxil. Patients switched to Atripla from a PI-based regimen may have a reduced response to therapy – monitor viral load and adverse reactions. Appropriate precautions must be used to prevent the risk of transmission of HIV to others through sexual contact or contamination with blood. Hepatic: Discontinue Atripla in patients developing symptomatic hyperlactataemia, metabolic/lactic acidosis, progressive hepatomegaly or rapidly elevating aminotransferase levels. Use with caution in patients with hepatomegaly, hepatitis, other risk factors for liver disease and hepatic steatosis, co-infection with HCV and treatment with alpha interferon and ribavirin – monitor closely. Caution in administering Atripla to patients with mild or moderate liver disease. Patients with pre-existing liver dysfunction should be monitored; interruption or discontinuation of treatment must be considered if evidence of worsening liver disease or persistent elevations of serum transaminases >5 times ULN. HBV Co-infection: Patients with HIV co-infected with either HBV or HCV treated with combination antiretroviral therapy are at increased risk of severe and potentially fatal hepatic adverse reactions. Discontinuation of therapy may be associated with severe acute exacerbations of hepatitis. Co-infected HIV/HBV patients should be closely monitored for at least four months following discontinuation of Atripla for symptoms of severe acute exacerbations of hepatitis. Psychiatric: Advise patients to contact their doctor immediately if they experience psychiatric symptoms such as severe depression, psychosis or suicidal ideation. Nervous system symptoms such as dizziness, insomnia, somnolence, impaired concentration and abnormal dreams may begin during the first 1 or 2 days of therapy and generally resolve after the first 2 4 weeks. Exercise caution in any patient with a history of seizures. Renal: Atripla is not recommended for patients with moderate or severe renal impairment. Avoid use of Atripla with concurrent or recent use of nephrotoxic medicinal product. If concomitant use of Atripla with a nephrotoxic agent is unavoidable, monitor renal function weekly. Renal failure and impairment, elevated creatinine, hypophosphataemia and proximal tubulopathy (including Fanconi syndrome) have been reported with use of tenofovir disoproxil fumarate in clinical practice. It is recommended that CrCl is calculated in all patients prior to therapy initiation and renal function monitored every 4 weeks for the first year and every 3 months thereafter. In patients at risk of renal impairment, consideration should be given to more frequent monitoring of renal function. If CrCl is decreased to <50ml/min or serum phosphate is decreased to <1.5mg/dl, renal function should be reevaluated within one week. Treatment with Atripla should be interrupted if CrCl is confirmed to be <50ml/min or if serum phosphate is decreased to <1mg/dl. Refer to SPC for further recommendations regarding monitoring, dose adjustment and discontinuation of therapy. Skin reactions: Discontinue Atripla in patients who develop severe rash associated with blistering, desquamation, mucosal involvement or fever. Lipodystrophy and metabolic: Combination antiretroviral therapy has been associated with lipodystrophy in HIV patients. Consider monitoring fasting serum lipids and blood glucose and manage lipid disorders as appropriate. Other: Administration of Atripla with food may increase efavirenz exposure. Mitochondrial dysfunction. Immune Reactivation Syndrome. Osteonecrosis. Decreased bone mineral density and bone abnormalities (infrequently contributing to fractures), which may be associated with proximal renal tubulopathy. Coadministration of Atripla and didanosine is not recommended as exposure to didanosine is significantly increased. Avoid in antiretroviral experienced patients with strains harbouring K65R, M184V/I or K103N mutations. Contains sodium – consider in patients on sodium-restricted diet. Interactions: Efavirenz is an inducer of CYP3A4 and an inhibitor of some CYP450 isoenzymes including CYP3A4. Other compounds that are substrates of CYP3A4 may have decreased plasma concentrations when co-administered with efavirenz. Efavirenz exposure may also be altered when given with medicinal products or foods (e.g. grapefruit juice) which affect CYP3A4 activity – see contraindications above. Atripla should not be co-administered with adefovir dipivoxil, lamivudine, atazanavir/ritonavir or didanosine. Avoid co-administration of Atripla with medicinal products that reduce renal function or compete for active tubular secretion (e.g. cidofovir). Avoid use of Atripla with concurrent or recent use of nephrotoxic medicinal product. Refer to SPC for drug interaction details for protease inhibitors, NRTIs, NNRTIs, antimicrobial and antifungal agents, anticonvulsants, antidepressants, cardiovascular agents, lipid-lowering agents, hormonal contraceptives, opioids and herbal products. Use in pregnancy and lactation: Atripla should not be used in pregnancy unless clearly necessary. Barrier contraception should always be used in combination with other methods of contraception. Avoid breast-feeding. Side effects: Very commonly reported adverse events (≥1/10): dizziness, headache, diarrhoea, nausea, vomiting, elevated creatine kinase, rash (all grades), hypophosphataemia*.
