Which medication is commonly used to treat essential tremor?

Dantrolene
Propranolol
Clonazepam
Amphetamine

The correct answer is: Propranolol

Propranolol is commonly used to treat essential tremor because it is a non-selective beta-blocker that has been shown to reduce the amplitude of tremors in many patients. The mechanism by which propranolol works is believed to involve the inhibition of the excitatory adrenergic stimulation that can exacerbate tremors. This medication is particularly effective for task-specific tremors and helps improve the quality of life for those affected by this condition. Dantrolene is primarily used for conditions like muscle spasticity and malignant hyperthermia, while clonazepam, a benzodiazepine, is often used for anxiety disorders and certain seizure disorders but is not a first-line treatment for essential tremor. Amphetamine, a central nervous system stimulant, is used to treat ADHD and narcolepsy and is not indicated for tremors, making it unsuitable for treating essential tremor. Thus, propranolol stands out as the most appropriate choice for managing this condition.
