Implication

Minoxidil may yield greater BP reduction than hydralazine in refractory hypertension; leaves open confirmation in randomized trials.

Key Points

This research aims to evaluate the efficacy and pharmacokinetics of minoxidil as an antihypertensive agent compared to hydrallazine.
Patients with refractory hypertension received combinations of minoxidil or hydrallazine with propranolol and hydrochlorothiazide.
Blood pressure was monitored before and after the addition of minoxidil and hydrallazine.
The study followed up to two years to assess efficacy and side effects.
Minoxidil reduced blood pressure to 142/92 mmHg compared to 168/108 mmHg with hydrallazine.
Patients experienced a prolonged duration of action with minoxidil without diminished response over two years.
Fewer side effects were observed with minoxidil in combination treatments, indicating its value in chronic hypertension therapy.
