Options in antihypertensive drug therapy. Help in choosing from among the many agents
1Overlake Internal Medicine, Bellevue, WA 98004, USA.
Insights
Diuretics and beta blockers are recommended first-line treatments for hypertension, but other drug classes offer effective alternatives. Personalized pharmacotherapy choice is crucial for optimal patient outcomes in managing high blood pressure.
Area of Science:
- Cardiology
- Pharmacology
- Internal Medicine
Background:
- The Joint National Committee V (JNC V) guidelines recommend diuretics and beta blockers as primary agents for hypertension treatment.
- These recommendations are based on their proven efficacy in reducing morbidity and mortality in long-term controlled trials.
Purpose of the Study:
- To highlight the importance of considering alternative antihypertensive drug classes beyond diuretics and beta blockers.
- To emphasize personalized pharmacotherapy selection based on individual patient profiles and comorbidities.
Main Methods:
- Review of existing hypertension treatment guidelines and clinical trial data.
- Discussion of the utility of various antihypertensive drug classes in specific patient populations.
Main Results:
- While diuretics and beta blockers are established first-line agents, other drug classes are effective and well-tolerated.
- Angiotensin-converting enzyme inhibitors are beneficial for patients with hypertension and heart failure or diabetic nephropathy.
- Calcium channel blockers may be advantageous for patients with hypertension and angina.
Conclusions:
- Practitioners should consider a broader range of antihypertensive medications.
- Individual patient factors and comorbidities should guide the selection of pharmacotherapy for hypertension.
- Future prospective studies comparing drug classes are needed to further guide hypertension management.
Abstract:
The fifth report of the Joint National Committee on Detection, Evaluation, and Treatment of High Blood Pressure (JNC V) states that "because diuretics and beta blockers are the only classes of drugs that have been used in long-term controlled trials and shown to reduce morbidity and mortality, they are recommended as first choice agents unless they are contraindicated or unacceptable." These guidelines are important, but practitioners should remember that many effective and well-tolerated classes of drugs are available for treating hypertension, and one may have greater usefulness than another in a given patient. For example, an angiotensin-converting enzyme inhibitor may be appropriate in a patient with hypertension and congestive heart failure or diabetic nephropathy. A calcium channel blocker may be beneficial in a patient with hypertension and concomitant angina. Results of prospective studies comparing classes of antihypertensive drugs and measuring clinically significant end points may help guide pharmacotherapy in the future.
