Thiothixene (sold as Navane) is a thioxanthene drug used as a typical antipsychotic medication. It is a thioxanthene derivative and is the cis isomer of N,Ndimethyl- 9-[3-(4-methyl-1-piperazinyl)-propylidene] thioxanthene-2-sulfonamide.
Navane is a first generation of antipsychotics, known as typical antipsychotics. Drugs in the second generation, known as atypical antipsychotics, have more recently been developed. Both classes of medication tend to block receptors in the brain's dopamine pathways, but antipsychotic drugs encompass a wide range of receptor specificity.
