Tiospirone (TSP) is an atypical antipsychotic drug. Tiaspirone appeared to be a promising antipsychotic agent as it didn`t cause extrapyramidal syndromes. It has 5HT-2 antagonistic properties as well as affinity for D2, 5HT-1a, 5HT-6 and sigma receptors. Tiospirone was in phase III clinical trials for the treatment of attention hyperactivity disorder with Mead Johnson in the USA but its development appears to have been discontinued.

Sample Use Guides

In Vivo Use Guide

After a single 75 mg dose of tiospirone, demonstrable levels of dopamine binding activity were present. A variety of time points were sampled during the multiple dose study wherein subjects received 60 mg, t.i.d. for 28 days.

Route of Administration: Oral

In Vitro Use Guide

Tiaspirone was found to be a competitive, reversible inhibitor of the sodium-dependent high-affinity choline uptake (SDHACU) by crude hippocampal and striatal synaptosomal preparations, giving IC50 values of respectively 3.69 microM and 1.14 uM.
