Antihypertensives 🧯
💡 Overview
- Antihypertensives are medications used to lower blood pressure and reduce cardiovascular risk.
- Classes include ACE inhibitors, ARBs, beta-blockers, calcium channel blockers, and diuretics.
- Choice depends on comorbidities, side-effect profile, and patient-specific factors.
📋 Common Considerations
- Monitor renal function and electrolytes, especially with ACEi/ARBs and diuretics.
- Be aware of postural hypotension in elderly patients.
- Titrate doses carefully and assess for side effects like cough (ACEi), bradycardia (beta-blockers), or edema (CCBs).
