This is a drug used in the treatment of cardiac failure and hypertension.
Mode of action:
There is a fall in blood pressure and consequent reflex tachycardia as a result of the peripheral arteriolar dilatation caused by hydralazine. Thus, in the treatment of hypertension, a beta-adrenoreceptor blocker is also is used. There is little reflex tachycardia when this drug is used to treat cardiac failure because there is no significant change in blood pressure.
