title: Nicardipine. A review of its pharmacology and therapeutic efficacy in older patients.
abstract: Nicardipine is a second generation dihydropyridine calcium antagonist which selectively inhibits vascular smooth muscle contraction. In elderly patients, the drug has demonstrated clinical efficacy in the management of hypertension, angina pectoris and ischaemia-related cerebrovascular disease. In particular, nicardipine effectively controls blood pressure in elderly hypertensive patients with or without coexistent disease. In noncomparative trials, a regimen containing nicardipine has been associated with an improvement of symptoms in hypertensive patients with concurrent coronary artery, cerebrovascular or peripheral vascular disease, while in essentially 'healthy' elderly hypertensive patients, nicardipine monotherapy has resulted in improved indices of mobility and cognitive function. As yet, however, there is no evidence that nicardipine (and/or other calcium channel antagonists) decreases cardiovascular morbidity and mortality in elderly patients, as has been demonstrated for more established antihypertensive therapies, namely diuretics and/or beta-blockers. The pharmacokinetic properties of nicardipine in elderly hypertensive patients appear to be similar to those in younger patients. The main adverse events associated with nicardipine in the elderly are related to the vasodilator properties of the drug and include pedal oedema, headache and flushing. However, the drug does not exacerbate spontaneous postural hypotension in the elderly, nor does it adversely affect the coronary artery disease risk profile, even in patients with type II diabetes mellitus. In summary, widespread clinical experience in the elderly indicates that nicardipine monotherapy or a regimen containing nicardipine is useful for the treatment of hypertension, particularly in patients with coexistent coronary artery, cerebrovascular or peripheral vascular disease. Nicardipine monotherapy has also demonstrated efficacy in angina pectoris and shown promise in the management of ischaemia-related cerebrovascular diseases, notably subarachnoid haemorrhage.
