For elderly patients with systolic hypertension without comorbidities, the preferred antihypertensive drugs are calcium channel blockers, which are commonly used clinically, such as nifedipine controlled-release tablets, nifedipine sustained-release tablets, amlodipine, nimodipine, etc. Calcium channel blockers have good antihypertensive efficacy for elderly patients. Diuretics also have good antihypertensive effects on hypertension in the elderly, especially salt-sensitive hypertension. Depending on the blood pressure level and condition, in addition to these two categories, the likes of beta-blockers, angiotensin-converting enzyme inhibitors, and angiotensin II receptor antagonists are also available. The more commonly used ones in the clinic are betalactam extended-release tablets, enalapril, valsartan, irbesartan and so on.
