Summary

The aim of this study was to evaluate the medium term effects of the selective α1-adrenenergic-blocker terazocin on atrial natriuretic peptide (ANP) levels in patients with moderate essential hypertension. The drug was give orally for 30 days. The daily dose was 1 mg for the first 7 days, 2mg for the next 7 days and 5mg for the remaining period of this clinical trial. At the end of this clinical trial, plasma ANP levels increased by 16.40% despite the drop in blood pressure while left atrial and ventricular diameters remained unchanged. These findings indicate that the increase of ANP plasma levels is not the result of a mechanical load on the left cardiac chambers but the result of a pharmacological action. These observations also indicate that terazocin exerts part of its antihypertensive action by increasing ANP plasma levels.
