Introduction
Hypertension affects nearly half of American adults. Fortunately, a wide range of effective blood pressure medications are available, and most are affordable generics.
ACE Inhibitors
Lisinopril, enalapril, and ramipril block the conversion of angiotensin I to II, relaxing blood vessels. Common side effect: dry cough in about 10% of patients.
ARBs
Losartan, valsartan, and olmesartan block angiotensin II receptors, providing similar benefits to ACE inhibitors without the cough. First choice for patients who develop ACE inhibitor cough.
Calcium Channel Blockers
Amlodipine and nifedipine relax blood vessel walls by preventing calcium from entering smooth muscle cells. Often combined with other agents for additive effect.
Thiazide Diuretics
Hydrochlorothiazide and chlorthalidone reduce blood volume and vessel resistance. Frequently used as first-line therapy or in combination regimens.
Beta-Blockers
Metoprolol, atenolol, and carvedilol reduce heart rate and output. Especially useful in patients with heart failure or post-myocardial infarction.
Combination Therapy
Most patients require two or more medications to reach target blood pressure of <130/80 mmHg. Fixed-dose combinations improve adherence.
Lifestyle Modifications
Reduce sodium intake, increase physical activity, maintain healthy weight, limit alcohol, and follow the DASH diet alongside medication therapy.
Monitoring Blood Pressure
Home blood pressure monitoring is recommended for most patients. Measure at the same time each day and keep a log to share with your healthcare provider.
Conclusion
Blood pressure control significantly reduces stroke, heart attack, and kidney disease risk. Work with your pharmacist to find the right regimen for your lifestyle.
