Side Effects & Adverse Reactions
The most common adverse effects of amlodipine are associated with vasodilatory action, such as dizziness, flushing, headache, hypotension and peripheral edema. Gastrointestinal disturbances, increased micturition frequency, lethargy, eye pain and mental depression may also occur. A paradoxical increase in ischaemic chest pain may occur at the start of the treatment and in a few patients excessive fall in blood pressure has led to cerebral or myocardial ischaemia or transient blindness. Rashes, fever and abnormalities in liver function due to hypersensitivity reaction of Acudipin may occur.
Warnings & Precautions
Precaution should be taken in patients with hepatic impairment and during pregnancy and breast feeding.
Pharmacology & Mechanism of Action
Amlodipine is a dihydropyridine calcium-channel blocker, with a long duration of action, used for the treatment of hypertension and angina pectoris. Amlodipine influences the myocardial cells, the cells within the specialized conducting system of the heart, and the cells of vascular smooth muscle. Administration of Amlodipine results primarily in vasodilation, with reduced peripheral resistance, blood pressure and afterload, increased coronary blood flow and a reflex increase in coronary heart rate. This in turn results in an increase in myocardial oxygen supply and cardiac output.
