Prescribing notes

Digoxin is indicated for rate control in atrial fibrillation and symptomatic heart failure; it has
no role in the prophylaxis of atrial fibrillation.

For rapid rate control in atrial fibrillation, a loading dose of digoxin may be given
intravenously or orally.

Regular measurements of plasma digoxin concentrations are not usually required except to
confirm toxic or sub-therapeutic levels, or to check compliance.

Digoxin should be used with particular caution in the elderly and patients with renal
impairment.

Hypokalaemia predisposes to digoxin toxicity.

Digoxin levels may be increased by drugs such as amiodarone, calcium channel blockers,
quinine, hydroxychloroquine.
Older Patients - Digoxin
Loading and maintenance doses of digoxin should be adjusted according to renal function: age,
sex and weight need to be considered. A lower maintenance dose (i.e. 62.5-125 micrograms daily)
is usually adequate in older patients.

Prescribing notes

Amiodarone may cause corneal microdeposits, thyroid dysfunction, pneumonitis, peripheral
neuropathy and hepatotoxicity. Liver-function and thyroid-function tests should be performed
before treatment, and 6 monthly thereafter; chest X-ray should be done before treatment.

Patients receiving amiodarone should avoid exposure of the skin to direct sunlight or sun
lamps; a sunscreening product providing SPF 25 should be applied if amiodarone is
prescribed.

Amiodarone interacts with many drugs. There is a potential for drug interactions to occur for
several weeks (or even months) after treatment with it has been stopped.

Sotalol may cause atypical VT (torsades de pointes); it should be given with extreme caution
with drugs known to prolong the QT interval e.g. erythromycin, chloroquine, haloperidol,
lithium, tricyclic antidepressants, chlorpromazine. It should not be used for angina,
hypertension, thyrotoxicosis or secondary prevention after myocardial infarction. Sotalol
should be avoided in patients on diuretics or with hypokalaemia.

Prescribing notes

Sudden withdrawal of calcium-channel blockers may exacerbate angina; withdraw if
ischaemic pain occurs or worsens after starting treatment.

Short-acting formulations of nifedipine capsules have been associated with large variations in
blood pressure and reflex tachycardia; they are no longer recommended for angina or
hypertension.

Diltiazem is first choice calcium-channel blocker for angina if a beta-blocker cannot be used;
it is also given for hypertension. It has less negative inotropic effects than verapamil and
significant myocardial depression is rare. Use caution if given with beta-blockers due to risk
of bradycardia. The most cost-effective brand should be prescribed.

Verapamil is used for angina, hypertension and arrhythmia; it reduces cardiac output, slows
the heart rate and may affect atrioventricular conduction. It should not be used with betablockers.

efficacy in combination with other anti-anginal drugs.

Ivabradine is approved for use, on the initiation of a cardiologist, chronic stable angina in
patients for whom heart rate control is desirable and also have a contra-indication or
intolerance of beta-blockers and rate limiting calcium channel blockers.

Ivabradine is also approved for use, on the initiation of a specialist, for chronic heart failure
NHYA class II to IV with systolic dysfunction, in patients in sinus rhythm and whose heart
rate is ≥75 beats per minute (bpm), in combination with standard therapy including betablockers therapy or when beta-blockers therapy is contraindicated or not tolerated.

In patients prescribed ivabradine the resting ventricular rate should not drop below 50bpm.

Ranolazine is indicated as adjunctive therapy in the treatment of stable angina in patients
inadequately controlled or intolerant of first-line antianginal therapies.

Prescribing notes

See Trust “Unfractionated Heparin Dosing Guidelines”.

See Trust Thrombophylaxis guidelines on use of LMWHs.

Treatment with standard heparin is continued until no longer required, or until warfarin takes
effect (at least 3 days).

Heparin is monitored using activated partial thromboplastin time (APTT) to give a
patient/control ratio of 2.0-3.0.

Low molecular weight heparin does not require APTT monitoring; if necessary, anti-factor Xa
can be monitored.

Heparins may induce two types of thrombocytopenia: the first, usually develops within 1-4
days of initiation, is acute, usually mild, and may resolve spontaneously. The second type has
an immunological basis and is more serious: it usually occurs after 7-11 days, or more
quickly in previously exposed patients, and is often associated with serious thromboembolic
complications or bleeding. Serial platelet counts should be measured if heparin is given for
longer than 5 days (or sooner if previously exposed), and heparin stopped if
thrombocytopenia develops.

Protamine sulphate reverses the effects of standard heparin, but only partially reverses the
effects of low molecular weight heparins.


Rivaroxaban 10mg, 15mg and 20mg tablets - approved for use as per NICE TA157 as a treatment option
for the prevention of VTE after elective hip or knee replacement, and for use as per NICE TA249 as a
treatment option for the prevention of stoke & systemic embolism in patients with AF. For both indications
the preferred treatment options locally are warfarin or dabigatran, but rivaroxaban is in option in those
patients who require their medication in a compliance aid. The current commissioned pathway for DVT/PE
prevention or treatment does not yet include rivaroxaban so it should not be prescribed for this indication.


available on individual patient basis as per NICE Technology Appraisal TA245 for the prevention of VTE
after elective hip or knee replacement, OR as per NICE Technology Apprasisal TA275 for preventing
stroke and systemic embolism in people with nonvalvular atrial fibrillation.
Dose
- Warfarin tablets 500micrograms (white), 1mg (brown), 3mg (blue), 5mg (pink): induction dose
10mg daily for 2 days, then adjusted according to INR. A lower induction dose may be required by
some patients; see BNF for details.
Prescribing notes

See Trust “GUIDELINES FOR WARFARIN- INDUCTION and MAINTENANCE DOSES”

The warfarin dose is adjusted according to the international normalised ratio (INR). The
target INR should be clearly identified at initiation of therapy, and measured daily or on
alternate days initially, then at longer intervals (depending on response) then up to every 12
weeks.

Indication and duration of treatment should be clearly recorded at initiation of treatment; the
patient-held anticoagulant treatment booklet should be used. See BNF for details.

The plasma half-life of warfarin is 35 hours; a steady anticoagulant effect is achieved after
about one week. If immediate anticoagulation is required, heparin must be given
concomitantly.

There are many clinically important interactions with warfarin; clinicians are strongly advised
to consult BNF before prescribing.

Vitamin K (phytomenadione) can be given to reverse the effects of warfarin but takes 6-12
hours to become effective. Immediate reversal of the anticoagulant effect of warfarin may be
achieved with fresh frozen plasma or prothrombin complex concentrate; see BNF for details.
Specialist haematological advice should be sought.

Dabigatran is approved for use in hip and knee replacement surgery for prophylaxis of
venous thromboembolism.


Warfarin will continue to be the first line drug of choice for prevention of stroke in patients
with non-valvular AF but Dabigitran/Rivaroxaban/Apixaban be considered for patients with a
warfarin allergy or an absolute contra-indication to warfarin
(Dabigitran/Rivaroxaban/Apixaban may also be contra-indicated in some of these
indications). Please note that a bleeding risk that would lead to a contra-indication to
warfarin would also contra-indicate to Dabigitran/Rivaroxaban/Apixaban.
Older Patients - Warfarin
Warfarin should be used with caution in patients with confusion or a tendency to fall.

Dabigatran (Pradaxa▼): risk of serious haemorrhage – contraindications clarified and
reminder to monitor renal function
Article date: July 2012
Summary
Because of the risk of haemorrhage, dabigatran is contraindicated in a range of clinical conditions where the
patient is at significant risk of major bleeding (listed in the main article). Dabigatran is also now contraindicated with
dronedarone, and with the use of other anticoagulant agents, except when switching therapy to or from dabigatran,
or with the use of unfractionated heparin for maintenance of venous or arterial catheter patency.
In addition, as exposure to dabigatran is substantially increased in patients with renal insufficiency, renal function
should be assessed in all patients before starting dabigatran and at least once a year in patients older than 75
years or those with a suspected decline in renal function.Nicorandil is associated with a risk of
gastrointestinal ulceration, including perianal ulceration. Healthcare professionals should consider
nicorandil treatment as a possible cause in patients who present with symptoms of gastrointestinaltract ulceration

Dabigatran (Pradaxa▼): contraindicated in patients with prosthetic heart valve(s)
requiring anti-coagulant treatment, because of the risk of thrombosis and haemorrhage
Article date: March 2013
Summary
Dabigatran (Pradaxa) is now contraindicated in patients with prosthetic heart valves requiring anti-coagulant
treatment related to their valve surgery. This is regardless of the length of time elapsed since valve replacement
took place.
The contraindication is based on new clinical trial data in this population, which showed an increased frequency of
thromboembolic and bleeding events in the group of patients treated with dabigatran, compared with warfarin.

Prescribing notes

Lowering cholesterol is associated with reduced mortality and morbidity in patients at high
and moderate risk of, or with established, cardiovascular and cerebrovascular disease.

Pravastatin is less likely to interact with other drugs than atorvastatin or simvastatin and
may be preferred in certain situations, such as in patients receiving warfarin, digoxin or
ciclosporin.

Generic simvastatin is substantially lower cost than other lipid lowering agents.

Caution should be exercised when prescribing other drugs with statins. Simvastatin and
atorvastatin interact with many drugs including azole antifungals, macrolide antibiotics,
amiodarone, verapamil, grapefruit juice and warfarin. See BNF for full list of interactions.

Caution should be exercised when prescribing simvastatin 80mg daily due to the increased
risk of adverse effects.

Simvastatin: evidence supporting recent advice on dose limitations with concomitant
amlodipine or diltiazem
Article date: October 2012
Summary
In August 2012 we published advice that simvastatin is now contraindicated with concomitant use of certain
medicines, such as ciclosporin, danazol, and gemfibrozil. In addition, the recommendations for the maximum
dose of simvastatin have changed when used with a number of other medicines, including amlodipine and
diltiazem. These changes were driven primarily by concerns about an increased risk of myopathy and/or
rhabdomyolysis at higher plasma concentrations of simvastatin, which may result from such drug interactions.
Following further consideration by the Pharmacovigilance Expert Advisory Group of the Commission on Human
Medicines, this article summarises the evidence underlying the new advice that the maximum recommended
dose for simvastatin in conjunction with amlodipine and diltiazem is now 20 mg/day. The prescribed doses of
amlodipine and diltiazem need not be changed.

Simvastatin: evidence supporting recent advice on dose limitations with concomitant
amlodipine or diltiazem
Article date: August 2012
Summary
We have previously communicated on the increased risk of myopathy associated with use of high-dose simvastatin (80 mg
daily) – see Drug Safety Update May 2010.
Considering the risk of myopathy associated with simvastatin, recent analysis of clinical trial data, spontaneously reported
cases and drug- drug interaction studies has resulted in further changes to the simvastatin prescribing information.
The changes include contraindications to concomitant use with certain medicines and maximum dose recommendations
when simvastatin is taken with a number of other medicines, as these interactions may increase plasma concentrations of
simvastatin which is associated with an increased risk of myopathy and/or rhabdomyolysis. Key points to note are that:


Simvastatin is now contraindicated with ciclosporin, danazol and gemfibrozil
The maximum recommended dose for simvastatin in conjunction with amlodipine or diltiazem is now 20 mg/day


Statins: risk of hyperglycaemia and diabetes
Article date: January 2012
Summary
Statin use may be associated with a level of hyperglycaemia in some patients where formal diabetes care is
appropriate. The risk appears to be mainly in patients already at increased risk of developing diabetes.
However, the overall benefits of statins strongly outweigh any risks, including in those at risk of developing
diabetes or those with pre-existing diabetes.

There is an increased risk of myopathy associated with high-dose (80 mg) simvastatin. The 80-mg dose should
be considered only in patients with severe hypercholesterolaemia and high risk of cardiovascular complications
who have not achieved their treatment goals on lower doses, when the benefits are expected to outweigh the
potential risks.
