    Uses

    Treatment of stable angina pectoris

    Nicorandil is indicated for the symptomatic treatment of patients with stable angina pectoris who are inadequately controlled or have a contraindication or intolerance to first-line antianginal therapies (such as beta-blockers and/or calcium antagonists).

    Dosage

    Adults

    The recommended starting dose is 10 mg twice daily. A lower starting dose of 5 mg twice daily may be employed in patients particularly susceptible to headache. Subsequently, the dosage should be titrated upward depending on the clinical response. The usual therapeutic dosage is in the range 10 to 20 mg twice daily, although up to 40 mg twice daily may be employed if necessary.

    Elderly

    The recommended starting dose is 10 mg twice daily. A lower starting dose of 5 mg twice daily may be employed in patients particularly susceptible to headache. Subsequently, the dosage should be titrated upward depending on the clinical response. The usual therapeutic dosage is in the range 10 to 20 mg twice daily, although up to 40 mg twice daily may be employed if necessary.

    The lowest effective dose is recommended.

    Precautions and Warnings

    G6PD deficiency
    Gastrointestinal diverticula
    New York Heart Association class III failure
    New York Heart Association class IV failure
    Pregnancy

    Advise patient ability to drive or operate machinery may be impaired
    Monitor for skin, mucosal, ocular or gastrointestinal ulceration
    Advise patient to report any eye irritation promptly
    Consider discontinuation if skin, mucosal, ocular or GI ulceration occurs
    Withdrawal of drug should take place under a cardiologist's supervision
    Advise patient that the effects of alcohol may be potentiated

    Nicorandil can cause serious skin, mucosal, and eye ulceration; including gastrointestinal ulcers, which may progress to perforation, haemorrhage, fistula or abscess. Stop treatment if ulceration occurs and consider an alternative.

    Gastrointestinal perforations in context of concomitant use of nicorandil and corticosteroids have been reported. Caution is advised when concomitant use is considered.

    The tablets are sensitive to moisture, hence the patient should be advised to keep the tablets in their blister until intake. Each blister contains active substance-free silica gel tablets as desiccant in a separate blister segment which is marked accordingly. The patient must be advised not to take these. Although accidental intake of this desiccant is usually harmless, it may alter the scheduled intake of the active tablets.

    Pregnancy and Lactation

    Pregnancy

    Use nicorandil with caution in pregnancy.

    At the time of writing, there is insufficient experience concerning exposed pregnancies and their outcomes. The manufacturers report that animal studies have not shown any teratogenic effects. Nicorandil should not be used in pregnancy unless there is no safer alternative.

    The use of all medication in pregnancy should be avoided whenever possible; particularly in the first trimester. Non-drug treatments should also be considered. When essential, a medication with the best safety record over time should be chosen, employing the lowest effective dose for the shortest possible time. Polypharmacy should be avoided. Teratogens taken in the pre-embryonic period, often quoted as lasting until 14 to 17 days post-conception, are believed to have an all-or-nothing effect. Where drugs have a short half-life, and when the date of conception is certain, this may allow women to be reassured where drug exposure has occurred within this time frame. Further advice may be available from the UK National Teratology Information Service (NTIS) and through ToxBase, available via password on the internet ( www.toxbase.org ) or if this is unavailable at the backup site ( www.toxbasebackup.org ).

    Lactation

    Nicorandil is contraindicated in breastfeeding.

    At the time of writing, there is insufficient experience concerning the use of nicorandil during breastfeeding. It is unknown if nicorandil is excreted in human breast milk. Animal studies have shown that nicorandil is excreted in small amounts into breast milk. Avoid breastfeeding whilst taking nicorandil therapy.

    Neonates, infants born prematurely, those with low birth weight, those with an unstable gastrointestinal function or who have serious illnesses may require special consideration. For any infant, if a drug is prescribed to the nursing mother, it should be at the lowest practical dose and for the shortest time. When drug administration is unavoidable and breastfeeding is to continue, minimisation of exposure of the infant to the drug may sometimes be achieved by timing the maternal doses to just after a feeding episode. Infants exposed to drugs via breast milk should be monitored for unusual signs or symptoms. Interactions between the drug received by the infant from the mother's milk and medication prescribed for the infant should also be considered, for example, when the drug given to the infant may prevent metabolism of the drug received via breast milk.
