Gallopamil hydrochloride (Methoxyverapamil hydrochloride), a methoxy derivative of Verapamil, is a phenylalkylamine calcium antagonist. Gallopamil hydrochloride inhibits acid secretion in a concentration-dependent manner with an IC 50 of 10.9 μM . Gallopamil hydrochloride is a potent antiarrhythmic and vasodilator agent . In Vivo Gallopamil hydrochloride (Methoxyverapamil hydrochloride; i.v.; 0.2 mg/kg; for 5 min) markedly reduces ventricular tachycardia (VT) and totally prevents fibrillation (VF). Gallopamil significantly reduces systolic and diastolic blood pressure measured 5 min after injection without markedly influencing heart rate. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Animal Model: Male Wistar rats weighing 290-370 gDosage: 0.2 mg/kg Administration: i.v.; 5 min Result: Markedly reduced VT and totally prevented VF. Form:Solid
