Generic Chlorpromazine Information

Introduction

Chlorpromazine is a phenothiazine‑derived antipsychotic widely used for the management of mental‑illness disorders. The active compound, chlorpromazine, belongs to the group of low‑potency typical antipsychotics. In Hong Kong, the drug is prescribed by qualified physicians under the Pharmacy and Poisons Ordin and is available from licensed importers and pharmacies. Beyond its primary role in psychosis, chlorpromazine is also employed for severe nausea, hyperemesis, and certain movement disorders.

What is Chlorpromazine?

Chlorpromazine is the generic version of Thorazine, the original brand introduced by Janssen in the 195s. Both formulations contain the same active compound, chlorpromazine, and provide equivalent therapeutic effects. Our online pharmacy provides this generic alternative as a cost‑effective treatment option, sourcing the product from internationally accredited manufacturers that meet Hong Kong’s quality standards.

How Chlorpromazine Works

Chlorpromazine blocks dopamine D₂ receptors in the central nervous system, reducing dopaminergic transmission that underlies psychotic symptoms. It also antagonises serotonin 5‑HT₂, α‑adrenergic, histamine H₁, and muscarinic M₁ receptors, contributing to its sedative, anti‑emetic, and vasodilatory effects.

• Onset of action: Clinically observable effects on agitation or psychosis may appear within 30 minutes after oral administration, while full antipsychotic effect usually requires several days of continuous dosing.
• Duration: The drug’s half‑life ranges from 12–16 hours in adults, allowing twice‑daily dosing for most indications.
• Clearance: Hepatic metabolism via CYP2D6 and CYP1A2 is the principal route; renal excretion accounts for less than 10 % of the dose.

Conditions Treated with Chlorpromazine

• Schizophrenia and schizoaffective disorders – dopamine antagonism reduces positive symptoms such as hallucinations and delusions.
• Acute mania and bipolar disorder – sedation and reduction of psychomotor agitation aid stabilization.
• Severe agitation and delirium – rapid tranquilisation in intensive‑care or psychiatric settings.
• Nausea and vomiting (including chemotherapy‑induced) – anti‑dopaminergic action on the chemoreceptor trigger zone.
• Hyperemesis gravidarum (when other agents are contraindicated) – controlled under obstetric supervision.
• Restless‑leg syndrome and certain extrapyramidal disorders – off‑label use for symptom control.

In Hong Kong, the prevalence of schizophrenia is estimated at .5 % of the adult population, and psychiatric facilities frequently include chlorpromazine in formularies for its established efficacy and low acquisition cost.

Patient Groups Most Likely to Benefit

• Adults with first‑episode psychosis who require an initial, affordable antipsychotic.
• Patients with refractory agitation where rapid tranquillisation is essential.
• Individuals undergoing chemotherapy who experience breakthrough nausea despite standard anti‑emetics.
• Pregnant women with severe hyperemesis (after risk–benefit assessment by obstetricians).

Not appropriate for patients with a history of severe cardiovascular disease, uncontrolled glaucoma, or those taking medications that strongly inhibit CYP2D6 (e.g., fluoxetine) without dose adjustment.

Risks, Side Effects, and Interactions

Common

• Sedation / somnolence – dose‑related, may impair driving.
• Hypotension – orthostatic drops due to α‑adrenergic blockade.
• Dry mouth and constipation – anticholinergic effects.

Rare

• Photosensitivity reactions – skin erythema after exposure to strong light.
• Elevated serum prolactin – may cause galactorrhoea or menstrual disturbances.

Serious

• Neuroleptic malignant syndrome (NMS) – characterised by fever, rigidity, autonomic instability; requires immediate medical attention.
• Torsades de pointes – rare but possible with concomitant QT‑prolonging drugs.
• Severe hepatic impairment – can precipitate accumulation and toxicity.

Clinically Relevant Interactions

• CYP2D6 inhibitors (e.g., fluoxetine, paroxetine) – increase chlorpromazine plasma levels, raise risk of sedation and hypotension.
• Potent QT‑prolongers (e.g., ibutilide, certain macrolides) – additive risk of ventricular arrhythmias.
• Antihypertensive agents – may exacerbate orthostatic hypotension; blood pressure monitoring is advised.

Patients should disclose all current medications, including over‑the‑counter products and herbal supplements, to avoid harmful interactions.

Practical Use: Dosing, Missed Dose, Overdose

• Standard adult oral dose: 25 – 100 mg 2–3 times daily for psychosis; 10 mg 3 times daily for anti‑emetic purposes.
• Parenteral use: 10 mg intramuscular for acute agitation, repeat every 30 minutes as needed (max 30 mg in 24 h).

Missed dose: If a dose is remembered within 2 hours, take it; otherwise, skip and continue the regular schedule. Do not double the dose.

Overdose: Symptoms may include profound sedation, hypotension, and respiratory depression. Immediate medical attention is required; treatment focuses on supportive care, activated charcoal if within 1 hour, and monitoring of cardiac and respiratory function.

Precautions:

• Avoid alcohol, which potentiates central‑depressant effects.
• Take with food if gastrointestinal upset occurs; however, high‑fat meals may delay absorption slightly.
• Patients with hepatic or renal disease should start at the lowest dose and titrate cautiously.

FAQ

• Is chlorpromazine available in both brand‑name and generic forms in Hong Kong?
  Yes, chlorpromazine is marketed under the original brand Thorazine as well as generic versions produced by certified manufacturers. Our online pharmacy supplies the generic formulation, which contains the same active ingredient at a lower price.

• What storage conditions are recommended for chlorpromazine?
  The medication should be kept at controlled room temperature (20 – 25 °C), protected from light, moisture, and extreme heat. A standard pharmacy cabinet away from the bathroom is sufficient.

• Can chlorpromazine be imported for personal use in Hong Kong?
  Personal import of chlorpromazine is permitted only with a valid prescription from a licensed Hong Kong clinician and must comply with the Customs and Excise Department’s regulations on psychotropic substances.

• Does chlorpromazine have any formulation differences between regions (e.g., US vs EU vs Asia)?
  While the core active ingredient remains identical, excipients such as binders or fillers may vary by market. These differences rarely affect efficacy but can influence tolerability in patients with specific allergies.

• Are there specific manufacturer warnings for Asian populations?
  No region‑specific safety warnings have been issued for Asian patients. However, clinicians consider genetic variability in CYP2D6 metabolism, which can affect plasma levels and side‑effect risk.
