DHA-clozapine
DHA-clozapine (tentative trade name Clozaprexin) is an atypical antipsychotic drug candidate that was created and originally tested by chemists at Protarga, a small pharmaceutical in Pennsylvania, and scientists at Harvard University. It is a prodrug of clozapine; the fatty acid docosahexaenoic acid (DHA) was added to clozapine in order to increase penetration of the blood–brain barrier.
