Hypothesis
Does the aldosterone: renin ratio predict the efficacy of spironolactone over bendroflumethiazide in hypertension?
Conclusion
The study aims to determine if the aldosterone: renin ratio can predict better blood pressure control with spironolactone compared to bendroflumethiazide in hypertensive patients.
Supporting Evidence
- The study will include 120 hypertensive subjects.
- It aims to compare the effects of spironolactone and bendroflumethiazide on blood pressure.
- Randomisation will be stratified by aldosterone: renin ratio.
Takeaway
This study is trying to find out if a specific blood test can help doctors choose the best medicine for people with high blood pressure.
Methodology
A double-blind, randomised, crossover, controlled trial comparing spironolactone and bendroflumethiazide over 12 weeks each, with a 2-week washout period.
Potential Biases
Potential bias from including patients already on medication, which may affect the generalizability of the results.
Limitations
The study may be biased towards a secondary care population due to the inclusion of patients already on antihypertensive therapy.
Participant Demographics
Hypertensive subjects with varying aldosterone: renin ratios.
