Doxazosin as Combination Therapy for Patients with Stage 1 and Stage 2 Hypertension

The purpose of this paper is to review the role of doxazosin, a long-acting alpha(1)-blocker, as a component of combination therapy for patients with stage 1 and stage 2 hypertension and for patients with concomitant hypertension and hyperlipidemia or glucose intolerance. Recent studies that evaluated doxazosin as combination therapy in the treatment of patients with inadequately controlled hypertension and patients with concomitant hypertension and other disorders were reviewed. Data extraction was based on the tolerability and efficacy data of doxazosin in patients with hypertension. Compared with placebo, doxazosin combination therapy leads to significant improvements in sitting and standing blood pressure. Doxazosin is well tolerated, with only minor adverse effects (e.g., headache, dizziness) as the most commonly reported treatment-related complications. The studies described demonstrate that doxazosin is effective as combination therapy for patients with stage 1 and stage 2 hypertension. The positive effects of doxazosin on serum lipids make combination therapy with doxazosin an attractive treatment option for patients who have concomitant hyperlipidemia or glucose intolerance.
