title: Meta-analysis of three trials with quinapril in the treatment of mild-to-moderate hypertension in the Mexican population.
abstract: A meta-analysis was performed to examine the therapeutic effect of quinapril in the treatment of patients with mild-to-moderate hypertension. Data from three clinical trials conducted in Mexico and including a total of 426 patients were examined using a retrospective approach and statistical methods. The meta-analysis proved that quinapril induces positive diastolic and systolic responses at all the doses studied, particularly at the 10-mg dose. At this dose, 94.1% of patients reduced their diastolic blood pressure (DBP) by 10 mm Hg or attained a DBP of < or = 90 mm Hg. Overall, quinapril reduced DBP by between 14.8 and 24.8 mm Hg proportionally to the baseline DBP. Systolic blood pressure decreased 16 to 35.7 mm Hg from baseline levels. We conclude that the meta-analysis allowed a clearer and more dependable handling of the results regarding effectiveness and optimum dose of quinapril.
