In a double blind, placebo-controlled study the effects of daily oral administration of 3-cyano-imipramine on the 3H-serotonin uptake capacity of platelets were investigated in healthy volunteers. The initial dose was 1 mg, rising to 3 mg daily for 7 days. A rapid and profound inhibition of 3H-serotonin uptake was observed in platelets isolated from the treated subjects. During repeated administration, uptake was reduced to less than 10% of pre-drug values. Five days after the final dose uptake had only partially recovered, to 53% of pre-drug values. A similar inhibition profile was observed when serum from the treated subjects was incubated with normal platelets and 3H-serotonin. The results establish 3-cyano-imipramine as a potent inhibitor of platelet serotonin uptake in humans.

D012701 Serotonin A biochemical messenger and regulator, synthesized from the essential amino acid L-TRYPTOPHAN. In humans it is found primarily in the central nervous system, gastrointestinal tract, and blood platelets. Serotonin mediates several important physiological functions including neurotransmission, gastrointestinal motility, hemostasis, and cardiovascular integrity. Multiple receptor families (RECEPTORS, SEROTONIN) explain the broad physiological actions and distribution of this biochemical mediator. 5-HT,5-Hydroxytryptamine,3-(2-Aminoethyl)-1H-indol-5-ol,Enteramine,Hippophaine,Hydroxytryptamine,5 Hydroxytryptamine
