Generic Mellaril Information

Introduction

Mellaril (thioridazine) is a phenothiazine antipsychotic used primarily to treat schizophrenia and other psychotic disorders. In Hong Kong, it is classified under the “Mental illness” medication group and is available through specialty pharmacies and, increasingly, through online pharmacy services. The active compound, thioridazine, exerts dopaminergic antagonism, which helps alleviate hallucinations, delusions, and severe agitation. Although thioridazine has largely been supplanted by newer agents with more favorable safety profiles, it remains an option for patients who have not responded to alternative therapies or who experience intolerable side effects from other antipsychotics.

What is Mellaril?

• Classification: Thioridazine belongs to the phenothiazine class of typical antipsychotics.
• Development: First synthesized in the 195s, thioridazine was marketed under the brand name Mellaril by Hoffmann‑La Roche.
• Manufacturer: The original brand was produced by Roche; generic thioridazine is supplied by various international manufacturers that meet Good Manufacturing Practice (GMP) standards.

Mellaril contains the same active compound as generic thioridazine. While the brand name is still recognized in some markets, generic formulations are widely used to reduce cost.

How Mellaril Works

Thioridazine blocks dopamine D₂ receptors in the mesolimbic pathway, diminishing the neurotransmission that underlies psychotic symptoms. It also exhibits antagonism at histamine H₁, α₁‑adrenergic, and muscarinic receptors, contributing to its sedative and anticholinergic effects.

• Onset of action: Clinical improvement typically appears within 2–3 weeks of initiation, although full therapeutic effect may require 6–8 weeks.
• Duration: The drug’s half‑life is approximately 20 hours, allowing once‑daily dosing in most patients.
• Clearance: Thioridazine is metabolized primarily by hepatic CYP2D6; variations in CYP2D6 activity can affect plasma concentrations and risk of adverse events.

By reducing dopaminergic signaling, thioridazine alleviates positive psychotic symptoms (hallucinations, delusions) and, to a lesser extent, negative symptoms (social withdrawal, apathy).

Conditions Treated with Mellaril

• Schizophrenia (including chronic and treatment‑resistant forms).
  • Prevalence in Hong Kong is estimated at .5–1 % of the adult population, aligning with global rates.
• Acute psychotic episodes associated with bipolar disorder or substance‑induced psychosis.
  • Thioridazine’s sedative properties can be valuable during severe agitation.
• Behavioral disturbances in dementia when other options are contraindicated.
  • Use is limited to short‑term, low‑dose regimens due to safety concerns.

The drug’s potency at dopamine receptors makes it effective for the core symptoms of schizophrenia, while its additional receptor activity provides calming effects in acute agitation.

Who Is Mellaril For?

• Patients with schizophrenia who have not achieved adequate response with newer atypical antipsychotics (e.g., risperidone, olanzapine).
• Individuals who experience intolerable side effects (e.g., metabolic disturbances) from atypical agents.
• Those requiring a highly sedating option for short‑term management of severe agitation or psychotic crises.

Contraindications include:

• Known hypersensitivity to thioridazine or phenothiazines.
• Pre‑existing QT‑interval prolongation or cardiac arrhythmias.
• Severe hepatic impairment (due to altered metabolism).

Patients with a history of extrapyramidal symptoms, elderly patients with dementia, and those taking other QT‑prolonging drugs should be evaluated carefully before initiating Mellaril.

Risks, Side Effects, and Interactions

Common

• Sedation – Drowsiness, especially at the start of therapy.
• Anticholinergic effects – Dry mouth, constipation, blurred vision.
• Weight gain – Mild to moderate increase in appetite.

Rare

• Extrapyramidal symptoms (EPS) – Tremor, rigidity, akathisia.
• Hyperprolactinemia – Menstrual irregularities, galactorrhea.
• Photosensitivity – Increased risk of skin reactions on sun exposure.

Serious

• QT prolongation and torsades de pointes – Potentially fatal cardiac arrhythmia.
• Neuroleptic malignant syndrome (NMS) – Life‑threatening hyperthermia, muscle rigidity, autonomic instability.
• Severe hypotension – Resulting from α₁‑adrenergic blockade, particularly with rapid dose escalation.

Clinically relevant drug–drug interactions

• CYP2D6 inhibitors (e.g., fluoxetine, quinidine) may raise thioridazine plasma levels, increasing risk of QT prolongation.
• Other QT‑prolonging agents (e.g., sotalol, erythromycin, fluoroquinolones) have additive cardiotoxic effects.
• Anticholinergic drugs (e.g., diphenhydramine) may exacerbate dry mouth and constipation.

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

Practical Use: Dosing, Missed Dose, Overdose

• Starting dose: 25 mg orally once daily, usually administered at bedtime to mitigate sedation.
• Titration: Incremental increases of 25 mg every 3–5 days, targeting 200–800 mg/day depending on response and tolerability.
• Maximum recommended dose: 800 mg per day; higher doses have not demonstrated additional benefit and increase toxicity risk.

Missed dose: If a dose is missed and it is less than 12 hours until the next scheduled dose, take the missed dose; otherwise skip it and continue with the regular schedule. Do not double‑dose.

Overdose: Symptoms may include profound sedation, hypotension, and cardiac arrhythmias. Seek immediate medical attention; treatment focuses on supportive care, cardiac monitoring, and possible administration of activated charcoal if ingestion was recent.

Precautions:

• Take with food if gastrointestinal upset occurs; however, high‑fat meals may slightly delay absorption.
• Avoid alcohol or sedating antihistamines while initiating therapy, as additive CNS depression can occur.
• Monitor ECG regularly, especially in patients with cardiovascular risk factors or concomitant QT‑prolonging drugs.

FAQ

• What is the typical appearance of Mellaril tablets?
  Mellaril tablets are usually round, white to off‑white, bearing the imprint “THIO 25” for 25 mg strength. The appearance may vary slightly by manufacturer, but the imprint remains consistent for identification.

• Can Mellaril be stored at room temperature, or does it require refrigeration?
  Thioridazine tablets are stable at ambient temperatures (15–30 °C). They should be kept away from excessive heat, direct sunlight, and moisture; refrigeration is unnecessary.

• Is Mellaril subject to any special import restrictions in Hong Kong?
  Personal import of prescription medications for self‑use is permitted under Hong Kong customs regulations, provided the quantity does not exceed a three‑month supply and the importer retains a valid prescription copy. Our online pharmacy assists customers in complying with these requirements.

• How does thioridazine differ from newer atypical antipsychotics like olanzapine?
  Thioridazine is a typical antipsychotic with stronger dopamine D₂ antagonism and higher risk of cardiac and extrapyramidal side effects. Atypical agents generally have broader receptor profiles and lower propensity for EPS, but may cause metabolic disturbances.

• What clinical trials established the efficacy of thioridazine for schizophrenia?
  Early randomized controlled trials in the 196s demonstrated significant reduction in Positive and Negative Syndrome Scale (PANSS) scores compared with placebo. Subsequent meta‑analyses confirm modest efficacy, particularly in treatment‑resistant populations.

• Does thioridazine affect drug testing for employment or legal matters?
  Standard drug screens do not routinely test for phenothiazines. However, specialized forensic assays can detect thioridazine metabolites if specifically requested.

• Can I travel internationally while taking Mellaril?
  Yes, but maintain a supply sufficient for the duration of travel plus a buffer. Carry the medication in its original packaging with a copy of the prescription to avoid customs complications.

• Are there known differences in formulation between regions (e.g., US vs EU vs Asia)?
  The active ingredient remains thioridazine, but excipients such as lactose or magnesium stearate may vary. Regional formulations comply with local pharmacopeial standards; these differences rarely affect therapeutic outcome.

• What dietary considerations should I follow while on Mellaril?
  Avoid large amounts of grapefruit juice, which can inhibit CYP3A4 and indirectly affect thioridazine metabolism. Maintain a balanced diet, and stay hydrated to lessen anticholinergic constipation.

• Is there any evidence of thioridazine use in children or adolescents?
  Thioridazine is not approved for pediatric use; limited data exist, and safety concerns—particularly cardiac toxicity—preclude routine prescribing in younger populations.
