The effect of nimodipine on essential tremor.

We investigated the effect of nimodipine (30 mg qid) in 16 de novo patients with essential tremor in a double-blind placebo-controlled study in which we assessed tremor by clinical scorings, tremorgraphic recordings, and patient self-evaluation. Of the 15 patients who completed the study, eight improved. We conclude that nimodipine is effective in some patients with essential tremor.
