Prazosin ('Peripress'): a long-term study.
Current Medical Research and Opinion
|January 1, 1984
Summary
Prazosin effectively controlled hypertension in most patients, especially when combined with beta-blockers. Long-term use showed decreasing dosage needs and good tolerability, with most side effects occurring early.
Area of Science:
- Cardiology
- Pharmacology
Background:
- Moderate to severe hypertension requires effective long-term management.
- Prazosin is an antihypertensive agent with varying efficacy profiles.
Purpose of the Study:
- To evaluate the long-term effectiveness and tolerability of prazosin in hypertension.
- To determine optimal combination therapy for blood pressure control with minimal side effects.
Main Methods:
- Long-term follow-up study of 90 patients with moderate to severe hypertension.
- Prazosin administered alone or in combination with other antihypertensives (beta-blockers, diuretics).
- Average follow-up period of 5.3 years for 79 patients.
Main Results:
- Prazosin monotherapy was adequate for 6 patients.
- Over 80% achieved satisfactory blood pressure control (<90 mmHg diastolic) with prazosin and beta-blockers, with diuretics as needed.
- Decreasing prazosin dosage requirements observed over time, most notably after 2 years.
- Most side effects occurred within the first year; treatment generally well-tolerated.
Conclusions:
- Prazosin, particularly in combination with beta-blockers, is effective for long-term hypertension management.
- Adjustable dosing and decreasing requirements suggest potential for optimized long-term therapy.
- Early side effects are common, but overall tolerability is good for sustained use.
