What medication is commonly used to treat essential tremor?

• A. Propranolol
• B. Ibuprofen
• C. Acetaminophen
• D. Diazepam

Answer: (A)

Propranolol, a nonselective beta-adrenergic blocker, is commonly prescribed as a first-line treatment for essential tremor. By blocking beta receptors, it dampens peripheral adrenergic signaling that contributes to the tremor, often reducing tremor amplitude and improving handwriting and daily tasks. It’s well-supported for this use and frequently chosen before other options.

Ibuprofen and acetaminophen are pain relievers, not mechanisms that affect tremor. Diazepam can calm nerves and muscles but isn’t reliably effective for essential tremor and carries risks like dependence and sedation, making it a less favorable long-term choice. Propranolol’s targeted effect on the tremor makes it the best option among these.
