Patient's question:
No.Doctor's answer:
Hello, Isoptin is a selective calcium channel blocker that inhibits calcium ions from entering cells, with significant efficacy. The adverse effects include hypotension and can exacerbate atrioventricular block. The drug increases blood pressure, which excites the vagus nerve, making it more suitable for patients with paroxysmal supraventricular tachycardia accompanied by hypotension.
