Medications used to treat tremors

Tremor is one of the most common movement disorders, though it can arise in the context of several unrelated neurological disorders whose pharmacology and anatomical origins differ greatly. Treatment of tremors can take advantage of several medications and neurosurgical treatments. Medications useful for treating tremor are discussed in this review, including those for action tremor as seen in essential tremor, the resting tremor of Parkinson's disease, orthostatic tremor, cerebellar tremor, Holmes tremor, dystonic tremor, and drug-induced tremors. A medication that is useful for most types of tremors is the beta-blocker propranolol, though even in essential tremor it can fail to be effective at tremor control.
