| pubmed-article:6227228 | pubmed:abstractText | Trimazosin, a selective alpha-1-adrenoceptor-blocking agent, has been extensively evaluated in over 1000 patients. In hypertensive patients, reduction in elevated blood pressure in both supine and standing positions, consequent to a reduction in systemic vascular resistance, persisted in long-term therapy. Progression of hypertension target organ damage did not occur. Improvement in blood lipids with decreased total serum cholesterol was noted in long-term therapy. In long-term studies, 74% of patients responded at a trimazosin dose of 300 mg/day or less; the maximum dose was 300 mg/day or less in 52% of patients and 200 mg/day or less in 36%. Most patients received twice a day therapy. The side effect profile of trimazosin was comparable to placebo and significantly better than that of either methyldopa or propranolol. Concomitant disease or therapy did not adversely affect the trimazosin safety profile. Hematology, clinical chemistry, and urinary parameters did not indicate deleterious effects. Because of its excellent safety and toleration profile, trimazosin may be particularly suitable in first-line therapy of patients with mild or moderate hypertension. | lld:pubmed |
