Generic Compazine Information

Introduction

Compazine contains the anti‑dopamine agent prochlorperazine. It is classified among medications used for mental illness, primarily for its anti‑emetic and antipsychotic properties. In Hong Kong, prochlorperazine is prescribed for severe nausea, vomiting, and certain psychotic disorders. The drug is marketed by several manufacturers worldwide; local supply is limited, leading many patients to seek alternative sources.

What is Compazine?

Compazine is a brand‑name product whose active ingredient is prochlorperazine, a phenothiazine derivative. Prochlorperazine was first synthesized in the 195s and is approved for both anti‑emetic and antipsychotic indications. The medication is produced by multiple pharmaceutical companies that hold valid licences in their respective jurisdictions.

How Compazine Works

Prochlorperazine exerts its therapeutic effect by blocking dopamine D₂ receptors in the chemoreceptor trigger zone of the medulla and in the basal ganglia. Inhibition of dopamine signaling reduces the stimulation of the vomiting centre, thereby suppressing nausea and vomiting. The same dopaminergic blockade in the central nervous system produces antipsychotic activity, alleviating symptoms such as hallucinations and agitation.

Typical oral absorption occurs within 30 – 60 minutes, reaching peak plasma concentrations in about 2 hours. The drug’s elimination half‑life ranges from 5 to 8 hours, and hepatic metabolism through CYP2D6 results in renal excretion of inactive metabolites.

Conditions Treated with Compazine

• Acute and chemotherapy‑induced nausea and vomiting – Prochlorperazine is a first‑line anti‑emetic for patients undergoing cancer therapy or postoperative recovery.
• Vertigo and motion sickness – By acting on the vestibular nuclei, it diminishes dizziness and associated nausea.
• Schizophrenia and other psychotic disorders – The dopamine antagonism reduces positive psychotic symptoms such as delusions and auditory hallucinations.
• Severe anxiety‑related agitation – In emergency settings, low‑dose prochlorperazine can calm patients with acute agitation.

In Hong Kong, cancer incidence is high, and the local healthcare system often manages chemotherapy‑related emesis in public hospitals. Consequently, demand for effective anti‑emetics like prochlorperazine remains substantial.

Patient Groups Most Likely to Benefit

• Oncologic patients receiving highly emetogenic chemotherapy.
• Post‑operative patients with persistent nausea despite standard anti‑emetic regimens.
• Individuals with diagnosed schizophrenia or schizoaffective disorder who require an oral dopamine antagonist.
• Elderly patients with vestibular disorders where alternative anti‑vertigo agents are contraindicated.

Patients with a history of severe cardiac arrhythmia, prolonged QT interval, or known hypersensitivity to phenothiazines should avoid prochlorperazine unless a specialist determines a risk‑benefit advantage.

Risks, Side Effects, and Interactions

Common

• Drowsiness or somnolence
• Dry mouth
• Constipation
• Light‑headedness, especially when standing (orthostatic hypotension)

Rare

• Extrapyramidal symptoms (e.g., akathisia, dystonia)
• Restlessness or akathisia persisting after drug discontinuation
• Mild elevation of liver enzymes

Serious

• Neuroleptic malignant syndrome – a life‑threatening reaction characterized by fever, muscle rigidity, autonomic instability, and altered mental status.
• Torsades de pointes or other ventricular arrhythmias, particularly in patients with pre‑existing QT prolongation.
• Severe hypersensitivity reactions, including angioedema or anaphylaxis.

Drug‑Drug Interactions

• Anticholinergic agents (e.g., atropine) may worsen constipation and urinary retention.
• CYP2D6 inhibitors (e.g., fluoxetine, quinidine) can increase plasma concentrations of prochlorperazine, raising the risk of adverse events.
• Other dopamine antagonists may produce additive extrapyramidal effects.
• QT‑prolonging drugs (e.g., certain macrolide antibiotics, anti‑arrhythmics) heighten the chance of cardiac arrhythmias.

Patients must disclose all current medications, including over‑the‑counter products and herbal supplements, to their prescriber.

Practical Use: Dosing, Missed Dose, Overdose

Standard dosing (adult, oral or intramuscular):

• Nausea/vomiting: 5 – 10 mg every 6 hours as needed; maximum 40 mg per day.
• Schizophrenia: 5 – 10 mg three times daily; may be increased up to 30 mg per day based on response.

The tablet form should be swallowed whole with water. Intramuscular injection is reserved for severe nausea when oral intake is not possible.

Missed dose – Take the missed dose as soon as remembered unless the next scheduled dose is within 2 hours. In that case, skip the missed dose and resume the regular schedule; do not double‑dose.

Overdose – Symptoms may include severe drowsiness, hypotension, cardiac arrhythmia, and extrapyramidal signs. Immediate medical attention is required. Activated charcoal may be administered if presentation is early; supportive care with monitoring of cardiac rhythm is standard.

Precautions – Avoid alcohol, which can potentiate sedative effects. Use caution in patients with hepatic impairment, as metabolism is reduced. Pregnant women should only use prochlorperazine after risk assessment; it is classified as Pregnancy Category C in many jurisdictions.

FAQ

• Is Compazine available in both brand‑name and generic forms in Hong Kong?
  Yes. The brand‑name product is marketed as Compazine, while the same active ingredient, prochlorperazine, is also sold as a generic tablet. Generic versions are typically less expensive and are provided by multiple international manufacturers.

• Can I store Compazine at home without refrigeration?
  Compazine tablets should be kept at room temperature, away from direct sunlight, moisture, and heat sources. Refrigeration is not required and may cause condensation that could affect tablet integrity.

• What packaging does Compazine come in when ordered online?
  Orders from our online pharmacy are shipped in tamper‑evident, sealed blister packs or bottles with child‑resistant caps. Each package includes a medication information leaflet in English and traditional Chinese.

• Is it legal to import Compazine for personal use into Hong Kong?
  Importation of medication for personal use is permitted under Hong Kong regulations provided the product is accompanied by a valid prescription and conforms to the Personal Importation Scheme. Our service ensures all legal requirements are met before shipment.

• Are there specific manufacturer warnings for Asian populations?
  Some manufacturers note that Asian patients may exhibit a higher incidence of extrapyramidal symptoms at standard doses. Clinicians often start with the lower end of the dosing range and monitor closely for movement disorders.

• Does the formulation of Compazine differ between regions such as the US, EU, and Asia?
  The core active ingredient, prochlorperazine, remains the same worldwide. However, excipients such as fillers and binders can vary. Asian‑marketed tablets may contain lactose‑free formulations to accommodate local dietary preferences.

• Can Compazine be incorporated into a telemedicine treatment plan?
  Yes. Telemedicine providers can evaluate patients remotely, prescribe prochlorperazine, and coordinate fulfillment through our online pharmacy. All prescriptions undergo a professional evaluation to ensure safety.

• How long does it take for Compazine to relieve severe nausea after the first dose?
  Oral prochlorperazine usually begins to reduce nausea within 30 – 60 minutes, with maximal effect seen at about 2 hours. Intramuscular administration provides a faster onset, often within 15 minutes.

• What should I do if I experience a new rash after starting Compazine?
  A rash may indicate an allergic reaction. Discontinue the medication immediately and seek medical attention, especially if the rash is accompanied by swelling, difficulty breathing, or fever.

• How does Compazine interact with anti‑psychotic medications like risperidone?
  Concomitant use of two dopamine antagonists can increase the risk of extrapyramidal symptoms and QT prolongation. Clinicians typically adjust doses or select alternative agents to minimize additive effects.
