🧠 Introduction to Chlorpromazine
Chlorpromazine is a first-generation antipsychotic from the phenothiazine class, manufactured by Sun Pharma. It blocks dopamine D2 receptors in the mesolimbic pathway, reducing hallucinations, agitation, and psychotic symptoms. Beyond psychiatry, it’s used off-label for:
-
🤢 Chemotherapy-induced nausea/vomiting (25–50mg every 4–6h)
-
😮 Intractable hiccups (25–50mg TID)
-
🌀 Tetanus-associated muscle spasms (IV administration)
Historically termed “chemical lobotomy” for its sedative effects, it remains vital in low-resource settings due to low cost.

🩺 Expert Commentary
Dr. Priya Mehta, Psychopharmacologist:
*”Chlorpromazine’s potent alpha-blockade makes it effective for acute agitation but demands caution in cardiac patients. For maintenance therapy, newer agents like [seroquel] (Quetiapine) offer better metabolic profiles. Always monitor QT interval with doses >100mg/day.”*
📌 Disclaimer
This information does not replace medical advice. Consult a healthcare provider before use. Sun Pharma’s Chlorpromazine is not FDA-approved for hiccups or nausea.
💡 Clinical Pearls:
-
Emergency Use: IM injection (25–50mg) for acute psychosis (onset: 15–30 min).
-
Antidote for Overdose: Norepinephrine (NEVER epinephrine due to reversed alpha effects).
