[Therapeutic effects of trazodone in the treatment of tremor. Multicentric double-blind study].

A 30 days therapeutical trial with trazodone has been performed in 47 patients suffering from different types of tremor. No significant improvement was detected in patients suffering from parkinsonian syndromes, multiple sclerosis, psycogenic tremor and hyperthyroidism. After the double-blind trial with trazodone, a significant improvement (p less than 0.025) was, instead, evident in 5 out of 6 patients with essential tremor, while the score did not change in the 3 patients with essential tremor who were treated with placebo.
