Effects of amitriptyline and mianserin on psychomotor skills and memory in man. 1978

M J Mattila, and R Liljequist, and T Seppälä

1. Twenty volunteers were treated with amitriptyline 25 mg, mianserin 10 mg, and placebo, three times daily for 2 weeks each, in a double-blind cross-over study. Tests of psychomotor function and of learning and memory, were carried out after consumption of alcohol or a placebo drink at intervals during each treatment period. 2. Coordinative and reactive skills were affected by mianserin on the first day only, but by amitriptyline up to day 7 in most of the tests. Both drugs seemed to interact additively with alcohol. 3. Amitriptyline impaired short-term memory span and acquisition, and alcohol enhanced these effects. Mianserin did not affect learning and memory, and did not interact with alcohol in this respect. 4. The differing effects of amitripyline and mianserin are considered in relation to anticholinergic properties.

D008803	Mianserin	A tetracyclic compound with antidepressant effects. It may cause drowsiness and hematological problems. Its mechanism of therapeutic action is not well understood, although it apparently blocks alpha-adrenergic, histamine H1, and some types of serotonin receptors.

D010919	Placebos	Any dummy medication or treatment. Although placebos originally were medicinal preparations having no specific pharmacological activity against a targeted condition, the concept has been extended to include treatments or procedures, especially those administered to control groups in clinical trials in order to provide baseline measurements for the experimental protocol.
