verapamil/ve·rap·a·mil/ (vĕ-rap´ah-mil) a calcium channel blocker that dilates coronary arteries and decreases myocardial oxygen demand, used as the hydrochloride salt in the treatment of angina pectoris and of hypertension and the treatment and prophylaxis of supraventricular tachyarrhythmias.
A calcium channel blocker drug, C27H38N2O4, that acts as a coronary vasodilator and is used in its hydrochloride form to treat hypertension and certain cardiac arrhythmias.
a calcium channel blocker.
indications It is prescribed for the treatment of vasospastic and exertional angina, supraventricular tachycardia, atrial fibrillation, and atrial flutter.
contraindications Severe left ventricular dysfunction, hypotension, cardiogenic shock, sick sinus syndrome, or second- or third-degree atrioventricular (AV) block prohibits its use.
adverse effects Among the more serious adverse effects are hypotension, peripheral edema, AV block, bradycardia, congestive heart failure, pulmonary edema, constipation, and dizziness.
verapamilCardiology A CCB antiarrhythmic that slows transmission of impulses across the AV node and supresses the sinus node's intrinsic rhythm Indications Tachycardial supraventricular arrhythmias–eg, paroxysmal supraventricular tachycardia, A Fib with tachyarrhythmias, atrial flutter with rapid conduction, and is the parenteral emergency drug of choice Adverse effects Constipation, slowed AV conduction and sinus node automaticity, peripheral edema; it is a standard agent for managing HTN, especially in Pts with angina; it improves pain linked to obstructive cardiomyopathy, and prevents migraines Contraindications Severe left ventricular dysfunction, hypotension, sick sinus syndrome, 2º or 3º AV block, WPW, heart failure, or in Pts with accessory bypass tracts, WPW syndrome, peripheral edema; caution in renal failure.

verapamilA calcium channel blocker drug used to correct irregularities in the heart beat. There is evidence that verapamil and other calcium channel blockers are anti-atherogenic and can prevent recurrent narrowing of arteries, such as the coronary arteries after these have been widened by CORONARY ANGIOPLASTY. The drug is on the WHO official list. Brand names are Cordilox, Securon, Univer and Vertab SR. Formulated with trandolapril it is marketed as Tarka.
a calcium channel blocking agent used as a vasodilator and in the treatment of cardiac arrhythmias.
