Chlorpromazine: What It Is and Why It Matters

When working with chlorpromazine, a first‑generation antipsychotic prescribed for psychosis, severe nausea, and agitation. Also known as Thorazine, it blocks dopamine D2 receptors and helps calm symptoms. chlorpromazine belongs to the Typical antipsychotic class, which is a subset of Dopamine D2 receptor antagonists. These drugs are often the first line for managing schizophrenia and related disorders because they reduce dopamine‑driven hallucinations and delusions. At the same time, chlorpromazine’s anti‑emetic property makes it useful in oncology and post‑operative care. Understanding how it fits into these therapeutic areas helps patients and providers balance benefits with side‑effect risks.

Key Considerations When Using Chlorpromazine

First, dosage varies widely: adults may start at 25 mg daily and climb to 800 mg, split across multiple doses, depending on the condition and tolerance. Low‑dose regimens (25‑100 mg) are typical for nausea, while higher doses (200‑800 mg) target psychotic symptoms. Second, monitoring is crucial. Because chlorpromazine can trigger extrapyramidal symptoms—like tremor, stiffness, or tardive dyskinesia—regular movement assessments are a must. Blood pressure drops (orthostatic hypotension) also occur, so clinicians often check lying‑and‑standing vitals during the first weeks. Third, drug interactions matter: anticholinergics can mask early movement side‑effects, while CYP2D6 inhibitors (e.g., fluoxetine) can raise chlorpromazine levels, increasing sedation and cardiac risks. Fourth, patient education reduces surprises. Letting patients know that dry mouth, blurred vision, or constipation are common, but manageable with hydration, eye drops, or fiber, improves adherence. Finally, consider alternative agents when side‑effects become intolerable; newer atypical antipsychotics often have a lower EPS profile, though they bring their own metabolic concerns.

Putting these pieces together, chlorpromazine exemplifies how a single molecule can span several therapeutic worlds—psychosis control, nausea relief, and even short‑term sedation.
