| Bioactivity | Gallopamil hydrochloride (Methoxyverapamil hydrochloride), a methoxy derivative of Verapamil, is a phenylalkylamine calcium antagonist[1]. Gallopamil hydrochloride inhibits acid secretion in a concentration-dependent manner with an IC50 of 10.9 μM[2]. Gallopamil hydrochloride is a potent antiarrhythmic and vasodilator agent[3]. |
| 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[3]. Animal Model: |
