What does this imprint mean?

Active ingredient

Verapamil

Uses and warnings

No boxed warning. Contraindications include severe left ventricular dysfunction, hypotension (systolic BP <90 mmHg) or cardiogenic shock, sick sinus syndrome or second-/third-degree AV block without a pacemaker, and atrial fibrillation/flutter with an accessory bypass tract (e.g., WPW syndrome), where verapamil can paradoxically accelerate ventricular rate. Major warnings cover negative inotropic/chronotropic effects risking heart failure or bradycardia/AV block, elevated hepatic transaminases, and the need for caution in hepatic or renal impairment since verapamil's half-life is prolonged.

Verapamil Hydrochloride Tablets are indicated for management of vasospastic (Prinzmetal's variant) angina, unstable angina, and chronic stable angina; treatment of supraventricular tachyarrhythmias, including control of ventricular rate in atrial fibrillation or flutter and prevention of paroxysmal supraventricular tachycardia; and essential hypertension, to lower blood pressure, alone or in combination with other antihypertensives.
