Significant cost-saving with modification of antihypertensive therapy
1Department of Medicine, University of Cape Town.
Summary
Switching from nifedipine to reserpine and thiazide improved blood pressure control and significantly reduced treatment costs for hypertension patients. This alternative therapy demonstrated a 73% cost saving per patient over six months.
Area of Science:
- Cardiology
- Pharmacology
- Public Health
Background:
- Nifedipine is commonly prescribed for hypertension and chest pain.
- Concerns exist regarding nifedipine's side-effect profile and cost.
- Alternative antihypertensive regimens require evaluation for efficacy and cost-effectiveness.
Purpose of the Study:
- To assess the efficacy and safety of an alternative antihypertensive regimen.
- To evaluate the cost reduction associated with the new treatment plan.
- To determine the impact of switching from nifedipine to reserpine and thiazide.
Main Methods:
- A 6-month follow-up study of 30 patients at Somerset Hospital Outpatient Department.
- Patients previously treated with nifedipine were switched to a new regimen.
- The new regimen primarily included reserpine combined with a thiazide.
Main Results:
- Improved blood pressure control was observed after the treatment change.
- No serious side-effects were reported during the follow-up period.
- The monthly cost per patient decreased by 73%, from R54 to R14.
Conclusions:
- Alternative antihypertensive therapy using reserpine and thiazide is effective and well-tolerated.
- Significant cost savings can be achieved by optimizing antihypertensive drug choices.
- A more considered approach to selecting antihypertensive agents is recommended, with careful attention to dosage, particularly for reserpine (max 0.1 mg/day).
