When working with Compazine, the brand name for the phenothiazine drug prochlorperazine used to treat nausea, vomiting, and certain psychotic conditions. Also known as prochlorperazine, it belongs to the phenothiazine class of medications, which act by blocking dopamine receptors in the brain. This class also includes other antipsychotics and antiemetics that share similar mechanisms but differ in dosing and safety profiles. In short, Compazine is a type of anti‑nausea drug that requires careful dosing and monitoring because it can affect mood and movement.
Compazine works by blocking dopamine D2 receptors, a key step in the pathway that triggers nausea and psychotic symptoms. Because of this action, clinicians often prescribe it for chemotherapy‑induced vomiting, migraine‑related nausea, and acute psychosis. The drug’s phenothiazine backbone also gives it sedative properties, making it useful in emergency settings where rapid symptom control is needed. While the primary goal is to stop vomiting, the dopamine blockade can also calm agitation, which is why you’ll see it listed alongside other sedatives in hospital formularies. Understanding this dual role helps you anticipate both the benefits and the potential side effects like drowsiness or extrapyramidal symptoms.
When you consider side effects, think of the three main categories that keep appearing in clinical notes: neurological, cardiovascular, and metabolic. Neurological issues include dry mouth, blurred vision, and the infamous “tremor‑like” movements that can happen if the dose is too high. Cardiovascular concerns revolve around orthostatic hypotension, especially in older adults, and occasional changes in heart rhythm. Metabolic effects are usually mild but can involve weight gain or increased prolactin levels, which might lead to breast tenderness or menstrual changes. Because Compazine interacts with other dopamine‑blocking drugs, it’s essential to review a patient’s full medication list before adding it. This is where knowledge of drug interactions becomes critical for safe prescribing.
