If you’re asking, “What is the brand name for chlorpromazine?” you’re likely curious about this widely used medication. As a pharmacist with deep experience in psychiatric drugs, I can tell you that chlorpromazine—a first-generation antipsychotic—has a few well-known brand names, depending on where you are. Let’s dive into its brand names, generic roots, and uses, drawing from my expertise and BNF chlorpromazine references.
What Is Chlorpromazine?
Chlorpromazine is a phenothiazine antipsychotic used to treat schizophrenia, bipolar mania, chlorpromazine for hiccups, and severe anxiety (chlorpromazine for anxiety). It works by blocking dopamine D2 receptors (how does chlorpromazine work) and comes as tablets (e.g., chlorpromazine 25mg), syrup, or injections, with doses from 25–1000mg daily (chlorpromazine dosage). While it’s available as a generic, its brand names are iconic in pharmacy history.
Quick Fact: It was the first antipsychotic, launched in the 1950s.
What Is the Brand Name for Chlorpromazine?
Chlorpromazine has two primary brand names, varying by region:
1. Thorazine
- Where: Primarily the United States.
- Maker: Originally developed by Smith, Kline & French (now part of GSK).
- Status: Widely recognized, though generic versions dominate today.
2. Largactil
- Where: United Kingdom, Australia, and parts of Europe.
