Abstract

This study was aimed to evaluate the efficacy and tolerability of bisoprolol, in Indian patients diagnosed with stage I essential hypertension as first-line drug. This was an open-label, phase IV, multicentric prospective study. 239 outpatient centres across India. After ethical approval, patients who were willing to sign informed consent, who are newly diagnosed with JNC VII stage I essential hypertension (systolic blood pressure 140-159 mm Hg or diastolic blood pressure 90-99 mm Hg) and who are prescribed bisoprolol were enrolled in the study. Patients with significant organ disease or complications, women of childbearing age refusing reliable contraceptive method, patients with known contraindications (like symptomatic bradycardia, significant atrioventricular blockade, sick sinus syndrome) and patients with known hypersensitivity reactions to bisoprolol and unwilling patients were excluded. PRIMARY AND SECONDARY OUTCOMES MEASURES: The primary outcome measure was percentage of patients achieving blood pressure (BP) ≤140/90 mm Hg at the end of 12 weeks, while multiple secondary outcome measures were assessed. Of 2418 patients screened, 2161 patients were recruited (66.64% men, mean age 51.7±9.8 years, smokers 19.19%) and 2...Continue Reading
