Verapamil: A calcium channel blocker primarily used for chest angina, arterial hypertension, and supraventricular tachycardia. It can cause adverse reactions such as bradycardia, hypotension, and peripheral edema. Its effect is enhanced when combined with diuretics and vasodilators, and monitoring includes heart rate, blood pressure, and ECG for AV block (source).
Diltiazem: Similar to Verapamil, Diltiazem is used for chest angina, arterial hypertension, and supraventricular tachycardia. It shares adverse reactions like bradycardia, hypotension, and peripheral edema. Drug interactions include increased antihypertensive effects with diuretics and vasodilators, with monitoring of heart rate, blood pressure, and ECG for AV block (source).
Amlodipine: A calcium channel blocker indicated for chest angina and arterial hypertension. Common adverse reactions include dizziness, peripheral edema, and flushing. It interacts with protease inhibitors, azole antifungals, and macrolide antibiotics, which can increase its effects. Monitoring focuses on blood pressure and side effects like hypotension and bradycardia (source).
