Metoprolol in the treatment of neuroleptic-induced tremor: case report.

A case report is presented documenting definite beneficial effect of metoprolol, a beta-selective adrenoceptor antagonist, in alleviating neuroleptic-induced coarse tremors. The tremors could not be controlled with antiparkinsonian agents. Metoprolol may prove to be an effective alternative in managing such side effects as tremors. The possible mechanisms of action are discussed.
