Tindal (ACETOPHENAZINE)

Merck & Co. · FDA-approved approved Small molecule Quality 26/100

Tindal (acetophenazine) is a small molecule drug originally developed by Schering and currently owned by the same company. It targets the D(2) dopamine receptor and is used to treat psychotic disorders. Tindal was FDA-approved in 1961 and is now off-patent, meaning there are no active Orange Book patents. As a result, there are currently no generic manufacturers of the drug. Despite its off-patent status, key safety considerations for Tindal are not well-documented due to a lack of available information on its pharmacokinetics.
