Long-term antihypertensive therapy with prazosin plus a diuretic
Journal of Cardiovascular Pharmacology
|November 1, 1979
Summary
Prazosin effectively lowers blood pressure in mild hypertensives for up to one year. This study found sustained blood pressure reduction with prazosin, showing little tolerance and no significant change in heart rate.
Area of Science:
- Cardiovascular medicine
- Pharmacology
Background:
- Mild hypertension requires effective long-term management.
- Diuretic therapy is common but may need augmentation.
Purpose of the Study:
- To evaluate the efficacy and tolerability of prazosin in diuretic-treated mild hypertensives.
- To assess blood pressure and heart rate changes over a 1-year period.
Main Methods:
- Prazosin was administered to 21 patients with mild hypertension already on diuretics.
- Blood pressure and pulse rate were monitored at 1, 6, and 12 months.
- Patient compliance and side effects were recorded.
Main Results:
- Blood pressure was reduced by 9-12% at all follow-up points (1, 6, 12 months).
- Pulse rate remained essentially unchanged throughout the study.
- Three patients discontinued the study due to side effects, noncompliance, or relocation.
Conclusions:
- Prazosin demonstrates sustained efficacy in lowering blood pressure for up to 1 year in mild hypertensives.
- Little evidence of tolerance to prazosin was observed.
- Prazosin did not significantly alter heart rate during the treatment period.
