Influence of acute and chronic chlorimipramine treatment on the 5-HT receptor-mediated modulation of acetylcholine release from the cerebral cortex of freely moving guinea-pigs.

1. Acetylcholine (ACh) release from the cerebral cortex of freely moving guinea-pigs, implanted with epidural cups, was studied. 2. A single dose of chlorimipramine (Cl-Imip, 10 mg kg-1, s.c.), reduced the cortical ACh release both in normal and in chronically (10 mg kg-1 daily, s.c., for 14 days) Cl-Imip-treated guinea-pigs; the 5-HT3 antagonist MDL 72222… CONTINUE READING
