Beta blockade in lithium tremor.
نویسندگان
چکیده
Practolol, propranolol, and placebo have been tested on an objective test of lithium induced tremor. Both beta-blocking agents produced significantly more tremor than the placebo. It is argued that lithium induced tremor is closer to essential than to physiological tremor.

Beta-adrenoreceptor mechanisms in essential tremor: a comparative single dose study of the effect of a non-selective and a beta-2 selective adrenoreceptor antagonist.
In order to study the mode of action of beta-adrenoreceptor antagonists in essential tremor the efficacy of single oral doses of 2, 4 and 10 mg LI 32-468, a peripherally acting, selective beta-2 adrenoreceptor antagonist, was compared with a single oral dose of 120 mg propranolol in a randomised, double blind, placebo controlled trial. Both the lowest dose of LI and propranolol were shown to be...
متن کاملMetoprolol and propranolol in essential tremor: a double-blind, controlled study.
Single oral doses of propranolol (120 mg), metoprolol (150 mg) and placebo were given in a randomised, double-blind fashion to 23 patients with essential tremor. Both beta blockers were significantly more effective than placebo in reducing the magnitude of tremor. The decrease in tremor produced by metoprolol (47, sem 9%, n = 23) was not significantly different from that observed propranolol (5...
متن کاملBeta-adrenoreceptor mechanisms in essential tremor; a double-blind placebo controlled trial of metoprolol, sotalol and atenolol.
In order to elucidate the mode of action of beta-adrenoreceptor antagonists in essential tremor, the efficacy of chronic oral administration of metoprolol, atenolol and sotalol was compared in a randomised, double-blind placebo controlled trial in twenty-four patients. Only sotalol proved superior to placebo on both subjective and "objective" assessments. Metoprolol and sotalol produced compara...
متن کاملA Comparison of Serum Lithium Levels for Maintenance Therapy of Bipolar Mood Disorder
Numerous studies have been done on using low serum lithium levels for maintenance therapy of bipolar mood disorder over the past 30-40 years. In this study we sought for the most suitable serum lithium level that having longer relapse's interval periods and less side effects as to recommended it as a maintenance serum lithium level. Thus, we studied 90 patients with bipolar mood disorder (accor...
متن کاملEvaluation of the beta 2 adrenoceptor agonist/antagonist activity of formoterol and salmeterol.
BACKGROUND Salmeterol and formoterol have a lower intrinsic activity at beta 2 receptors than isoprenaline in human bronchus in vitro. The aim of the present study was to evaluate in vivo the beta 2 agonist/antagonist activity of salmeterol and formoterol at rest with low endogenous adrenergic tone, on exercise with raised endogenous adrenergic tone, and in the presence of fenoterol, an exogeno...
