A method for achieving blood pressure control expeditiously with oral minoxidil.
Twelve patients with essential hypertension were treated aggressively with oral minoxidil in order to achieve blood pressure control as expeditiously as possible. Pretreatment blood pressure ranged from 159/109 to 238/161 mm Hg. Following an initial dose of 5 mg, subsequent dosage increments were administered every 6 hr until a fall in blood pressure was observed. The size of additional doses was determined by the magnitude of, and response to, the lowest effective dose and the therapeutic objective. Over a time interval of 24 to 42 hr, the blood pressure was reduced to normal or near normal in each case. Untoward hypotension was uniformly avoided. Analysis of the relationship between blood pressure response and cumulative dose indicates that at suboptimal blood pressure responses, it is safe and efficacious to give half the antecedent cumulative dose as a single dose in arriving at the therapeutic objective. The use of such a regimen should be considered as an alternative to parenteral drug administration in severe hypertension when immediate control of blood pressure is not required.
