Uses of Card 2.5mg Tablet 10s

Amlodipine belongs to group of drugs called calcium channel blockers. Amlodipine relaxes (widens) blood vessels and improves blood flow. Amlodipine is used to treat high blood pressure (hypertension) or chest pain (angina) and other conditions caused by coronary artery disease.

Side Effects of Card 2.5mg Tablet 10s

Headache, peripheral oedema, fatigue, somnolence, nausea, abdominal pain, flushing, dyspepsia, palpitations, dizziness. Rarely pruritus, rash, dyspnoea, asthenia, muscle cramps. Potentially Fatal: Hypotension, bradycardia, conductive system delay and CCF.

Drug Interactions

Increased metabolism with rifampin. Reduced hypotensive effect with calcium. Potentiates effects of thiazide diuretics and ACE inhibitors. Avoid combination with β-blockers in patients with markedly impaired left ventricular function. May increase serum levels of CYP1A2 substrates e.g. aminophylline, fluvoxamine, ropinirole. CYP3A4 inhibitors (e.g. clarithromycin, doxycycline, isoniazid, nicardipine) may increase the effects of amlodipine. Additive BP-lowering effects when used with sildenafil, tadalafil or vardenafil.

Contraindications

Known hypersensitivity to dihydropyridines.

Mechanism of Action

Amlodipine relaxes peripheral and coronary vascular smooth muscle. It produces coronary vasodilation by inhibiting the entry of Ca ions into the voltage-sensitive channels of the vascular smooth muscle and myocardium during depolarisation. It also increases myocardial O2 delivery in patients with vasospastic angina. Absorption: Well absorbed from the GI tract (oral); peak plasma concentrations after 6-12 hr. Distribution: Protein-binding: 97.5%. Metabolism: Hepatic: Extensive. Excretion: Via urine (mainly as metabolites, 10% as unchanged); 35-50 hr (elimination half-life).

Special Precautions

Impaired liver or renal function, CHF, sick-sinus syndrome, severe ventricular dysfunction, hypertrophic cardiomyopathy, severe aortic stenosis. Caution when used in patients with idiopathic hypertrophic subaortic stenosis. Elderly, children. Pregnancy, lactation.
