Treatment of tardive dyskinesia with ceruletide.
1. Seven patients with TD were treated with a single dose of ceruletide 0.8 microgram/kg i.m. 2. EMG and MV were recorded, and the average power spectrum was computed. 3. Effect of ceruletide on TD within 2 hr after injection was varied (3 cases: inhibitory, 2 cases: facilitatory, 2 cases: no effect). 4. Two patients with severe TD, who showed improvement after a single administration, received repeated administration of ceruletide (0.6 microgram/kg i.m.) and their TD symptoms were recorded on videotape for blind consensus ratings. In both patients ceruletide caused a marked decrease in severity of TD, and the effects lasted for several weeks. 5. The present findings might contribute to further understanding of the role of CCK in the brain and to the treatment of TD.
