What are the first-line treatments for essential hypertension in adults?
First-line pharmacotherapy for essential hypertension in adults typically includes thiazide-type diuretics, calcium channel blockers, ACE inhibitors, or angiotensin receptor blockers. The choice depends on patient-specific factors including comorbidities, age, and ethnic background. Lifestyle modifications—including sodium reduction, weight management, regular physical activity, and moderation of alcohol intake—remain foundational to all treatment approaches.

Pharmacologic Options
Thiazide diuretics, CCBs, ACE inhibitors, and ARBs are all appropriate first-line agents. Beta-blockers are no longer recommended as first-line unless specific indications exist.
Lifestyle Modifications
Dietary sodium reduction, maintaining healthy body weight, regular aerobic exercise, and limiting alcohol consumption are recommended for all patients.
Points of Disagreement
Minor disagreement exists regarding initial choice between drug classes in uncomplicated hypertension. Some guidelines prefer ACE inhibitors while others consider all four classes equivalent.
