Which medication is most commonly used to treat essential tremor in older adults?

The most commonly used medication for treating essential tremor in older adults is long-acting propranolol. Propranolol is a non-selective beta-blocker that has been found to be effective in reducing the amplitude of tremors associated with essential tremor. Its efficacy in this context makes it a preferred choice, especially for older adults, who may be more vulnerable to the side effects of other medications.

Additionally, propranolol is generally well-tolerated, and its side effects can be managed effectively, which is particularly important in the geriatric population. The property of long-acting formulations helps maintain steady blood levels of the medication, leading to consistent therapeutic effects throughout the day.

Other medications mentioned, such as lisinopril, carbamazepine, and dopamine agonists, are not typically first-line treatments for essential tremor. While they may be used for other conditions or specific cases, they do not have the same established efficacy as propranolol for managing essential tremor symptoms. Thus, the preference for propranolol in clinical practice for treating this condition is well-supported by research and clinical guidelines.
