When is discontinuation of antihypertensive therapy indicated?
1Department of Medicine, University of Erlangen-Nürnberg, Germany.
Insights
Discontinuing high blood pressure medication may be possible for some patients. Factors like younger age and lower initial blood pressure improve success rates for stopping antihypertensive therapy.
Area of Science:
- Cardiology
- Pharmacology
- Internal Medicine
Background:
- Recent advances in managing hypertensive vascular disease.
- Challenges with long-term antihypertensive therapy include drug compliance, cost, and side effects.
- Intermittent therapy or medication withdrawal is being explored as an alternative.
Purpose of the Study:
- To clarify controversial results regarding antihypertensive medication withdrawal.
- To identify selection criteria for patients who may benefit from stopping medication.
- To critically review the possibility of normalizing hypertension and evaluate success rates.
Main Methods:
- Review of case reports, controlled, and uncontrolled studies.
- Analysis of factors predicting successful withdrawal of antihypertensive medication.
- Evaluation of the impact of lifestyle modifications on non-pharmacologic treatment duration.
Main Results:
- Younger age, normal body weight, low salt intake, and lower pretreatment blood pressure were associated with successful withdrawal.
- Patients on single-drug therapy with minimal target organ damage showed better outcomes.
- Dietary modifications (low-salt, weight loss) extended non-pharmacologic treatment periods.
Conclusions:
- Patient selection is crucial for successful antihypertensive medication withdrawal.
- Lifestyle modifications can support extended periods off medication.
- Further research is needed to determine optimal treatment durations before considering discontinuation.
Abstract:
Major advances have been established in the handling of hypertensive vascular disease in recent years. However, drug compliance, drug costs, and the side effects of antihypertensive agents have prompted the question of whether intermittent therapy or even possible removal of medication represents an alternative to life-long antihypertensive therapy. Several case reports, and controlled and uncontrolled studies, have focused on this subject, delivering promising but inconsistent results. In this review the attempt is made to clarify the controversial results in order to provide possible selection criteria for patients who can be assumed to benefit from the withdrawal of antihypertensive medication. In addition, the issue of whether a genuine hypertensive can ever become normal is critically reviewed, and an evaluation of the reported success rates is performed. Factors that predicted a successful withdrawal of medication were young age, normal body weight, low salt intake, low pretreatment blood pressure, successful therapy with one drug, and only minimal signs of target organ damage. Additional modification, such as a low-salt or a weight-loss diet, were demonstrated to extend the period of nonpharmacologic treatment. Nevertheless, further studies would be of great help in elucidating how long and how intensively hypertensive patients should be treated before the discontinuation of medication can be tested.
