Nicardipine versus propranolol in essential tumor.

To evaluate effect of the calcium-channel blocker nicardipine in essential tremor (ET), 14 patients with ET affecting upper limbs underwent a cross-over study with nicardipine (1 mg/Kg/day) and propranolol (160 mg/day). Evaluation (baseline and 1 month after each drug) was done by using the Fahn-Tolosa-Marin scale. Two patients withdrawed nicardipine (pretibial edema and palpitations) and other 2 propranolol (dyspnea and hypotension). Both drugs improved ET, with a non-significantly higher efficacy of propranolol. These results suggest that nicardipine might be efficacious for ET.
