Randomized Controlled Trial Multicenter Study Comparative Study
A double-blind, controlled, multicenter, randomized study comparing the antihypertensive effectiveness and tolerance of a daily dose of two nifedipine formulations: nifedipine microgranules versus nifedipine osmotic pump.
Controlled clinical studies have clearly established the advantages of blood pressure (BP) reduction. However, optimal control of BP in the population is still not adequate. Monotherapy is ineffective in the majority of hypertensive patients, and multidrug therapy increases costs. ⋯ Target BP was reached in more than 70% of patients receiving monotherapy with either formulation. Both formulations were tolerated well.
