Description
Curator's Comment: Description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/22918191 | https://www.ncbi.nlm.nih.gov/pubmed/16432504

Thioperamide is an antihistamine at H3 and H4 receptors. Thioperamide behaves as both antagonist and inverse agonist.Thioperamide is under preclinical development with Glaxo Wellcome (UK) for the treatment of short-term memory impairment. It has also demonstrated antiarrhythmic effects in preclinical trials. Active development of thioperamide appears to have been discontinued.

CNS Activity

Curator's Comment: Thioperamide is CNS active in animals. No human data available.
