Final answer:
If a patient is unable to take ACE inhibitors or ARBs, alternative medications for treating hypertension include beta-blockers, calcium channel blockers, and diuretics.
Step-by-step explanation:
If a patient is unable to take ACE inhibitors (ACE-I) or angiotensin receptor blockers (ARBs), alternative medications can be considered to treat hypertension. One option is to prescribe beta-blockers, which work by blocking the effects of adrenaline and reducing heart rate and blood pressure. Another option is to use calcium channel blockers, which relax and widen blood vessels, thereby reducing blood pressure. A third option is diuretics, which help remove excess fluid from the body, also leading to a decrease in blood pressure.
