Captopril in combination with hydrochlorothiazide: comparative efficacy vs perceived best therapy

Area of Science:

• Cardiology
• Pharmacology
• Clinical Trials

Background:

• Mild-to-moderate hypertension requires effective and safe treatment strategies.
• Comparative effectiveness of combination therapy versus standard care needs evaluation.

Purpose of the Study:

• To compare the efficacy and safety of captopril plus hydrochlorothiazide (HCTZ) against perceived best therapy for mild-to-moderate hypertension.
• To assess blood pressure reduction, treatment adjustments, and patient-reported outcomes.

Main Methods:

• An open-label, randomized, multicentre trial involving 2128 patients.
• Patients were treated with either perceived best therapy or captopril plus HCTZ for 10 weeks.
• Blood pressure, side effects, and well-being were monitored.

Main Results:

• Captopril plus HCTZ demonstrated a statistically significant reduction in systolic (3 mmHg) and diastolic (2 mmHg) blood pressure compared to perceived best therapy within 6 weeks.
• Dose adjustments and switching to captopril plus HCTZ improved blood pressure control in non-responders.
• Although withdrawals due to side effects and non-compliance were higher in the captopril plus HCTZ group, this group also reported fewer side effects and improved general well-being.

Conclusions:

• Combination therapy with captopril plus HCTZ is effective in managing mild-to-moderate hypertension.
• The regimen offers potential benefits in patient well-being without a clear increase in known captopril-associated side effects.
• Further research may be needed to optimize treatment adjustments in clinical trial settings.
