Generic Grisactin Information

Introduction

Grisactin is an oral antifungal medication whose active ingredient is Griseofulvin. It belongs to the class of antifungal agents that inhibit the growth of dermatophytes—the fungi that cause skin, hair and nail infections. In the United Kingdom, Grisactin is prescribed for a range of superficial mycoses, especially those that involve the keratinised tissues. The drug is supplied by a manufacturer that follows Good Manufacturing Practice (GMP) standards, and it is listed in the British National Formulary (BNF) as a recommended option for certain dermatophyte infections.

What is Grisactin?

Grisactin is a tablet formulation containing the antifungal agent Griseofulvin. It is classified as a synthetic polyene antifungal and is marketed for the treatment of dermatophyte infections of the skin, hair and nails. The medication was developed in the 195s and has been used worldwide for more than six decades. While the original brand‑name products such as Grifulvin V (Pfizer) and Gris-Actin have been available in several markets, Grisactin offers the same therapeutic molecule at a lower cost.

Grisactin is the generic version of Grifulvin V, containing the same active compound Griseofulvin. Our online pharmacy provides this generic alternative as a cost‑effective treatment option.

How Grisactin Works

Griseofulvin, the active component of Grisactin, interferes with fungal cell division by binding to tubulin, a protein that forms microtubules. This binding destabilises the fungal mitotic spindle, preventing the fungus from the normal segregation of chromosomes during mitosis. The result is a gradual inhibition of fungal growth rather than an immediate kill‑off.

Key pharmacological points:

• Absorption: Oral absorption is enhanced when taken with a fatty meal; bioavailability ranges from 30 % to 70 % depending on the formulation.
• Distribution: The drug is highly lipophilic and accumulates in keratinous tissues (skin, hair, nails), reaching concentrations up to 20‑times those in plasma, which underlies its efficacy for superficial infections.
• Onset of action: Clinical improvement is usually observed within 2‑4 weeks, but complete eradication can require 4‑12 weeks of therapy, especially for nail infections.
• Elimination: Griseofulvin is metabolised in the liver, primarily by oxidative pathways, and is excreted in urine and bile as both unchanged drug and metabolites. The terminal half‑life is approximately 6‑9 hours in healthy adults.

Conditions Treated with Grisactin

Grisactin is approved for the following dermatophyte infections, all of which are common in the UK population:

• Tinea corporis (ringworm of the body): Affects up to 5 % of the UK adult population annually, often presenting as circular erythematous plaques with raised borders.
• Tinea cruris (jock itch): Prevalence peaks in warm, humid climates; more common among men aged 20‑50.
• Tinea pedis (athlete’s foot): One of the most frequently reported skin conditions in primary care, affecting an estimated 10‑15 % of adults.
• Tinea capitis (scalp ringworm): Predominantly a paediatric condition but can persist into adulthood; caused mainly by Trichophyton and Microsporum species.
• Onychomycosis (fungal nail infection): Accounts for roughly 3 % of the UK adult population, with higher rates in individuals over 60 years.

Grisactin’s high affinity for keratinous tissue makes it particularly effective for infections where the fungus resides within thickened layers of skin or nail plate, allowing sustained drug levels at the site of infection.

Who is Grisactin For?

Grisactin is suitable for adult patients (≥ 18 years) who have been diagnosed with a dermatophyte infection that involves the skin, hair or nails, and for whom topical therapy alone is insufficient or impractical. Typical candidates include:

• Individuals with extensive or recurrent tinea corporis, cruris or pedis.
• Patients with scalp infection (tinea capitis) when systemic therapy is required.
• Adults with mild‑to‑moderate onychomycosis, especially when the infection is limited to a few nails.
• Persons who cannot tolerate or have contraindications to newer oral antifungals (e.g., terbinafine, itraconazole).

Grisactin is not recommended for:

• Patients with severe hepatic impairment (Child‑Pugh class C) because of reduced metabolism.
• Pregnant or breastfeeding women, as animal studies have shown potential fetal toxicity.
• Individuals taking drugs that strongly induce hepatic enzymes (e.g., rifampicin, carbamazepine) which can lower Griseofulvin concentrations.
• Patients with known hypersensitivity to Griseofulvin or any tablet excipients.

Risks, Side Effects, and Interactions

Common

• Gastrointestinal upset (nausea, abdominal cramps, loss of appetite) – reported in up to 20 % of users.
• Headache – mild to moderate intensity, often transient.
• Skin reactions (pruritus, mild erythema) – typically resolve without intervention.

Rare

• Photosensitivity – increased susceptibility to sunburn; patients should use sunscreen and protective clothing.
• Mild hepatotoxicity – transient elevation of liver enzymes (ALT, AST) in less than 2 % of patients; routine monitoring is advisable for long‑term courses.
• Hematologic changes – occasional leukopenia or thrombocytopenia; usually reversible after discontinuation.

Serious

• Severe hepatic injury – rare cases of acute hepatitis have been documented; discontinue immediately if jaundice or severe fatigue develops.
• Hypersensitivity reactions – urticaria, angioedema, or anaphylaxis; requires emergency medical attention.
• Peripheral neuropathy – extremely uncommon, presenting as tingling or numbness in extremities.

Drug–Drug Interactions

• Cytochrome P450 inducers (e.g., rifampicin, phenobarbital, carbamazepine) – may reduce Griseofulvin plasma levels, compromising efficacy.
• Oral contraceptives – Griseofulvin can decrease estrogen levels, reducing contraceptive effectiveness; supplemental non‑hormonal contraception is recommended.
• Warfarin – potential increase in anticoagulant effect; INR should be monitored closely.
• Antacids containing aluminium or magnesium – may impair absorption; separate administration by at least 2 hours.

Practical Use: Dosing, Missed Dose, Overdose

• Standard adult dosing: 500 mg to 1 g taken orally once daily for tinea corporis, cruris, pedis; for tinea capitis or onychomycosis, typical regimens involve 500 mg twice daily for 6‑12 weeks.
• Administration: Swallow tablets whole with a full glass of water; taking the dose with a fatty meal improves absorption.
• Missed dose: If a dose is forgotten, take it as soon as remembered unless it is close to the next scheduled dose; do not double‑dose.
• Overdose: Symptoms may include nausea, vomiting, dizziness, and headache. Seek immediate medical attention; supportive care is the mainstay of treatment.
• Precautions: Avoid alcohol, which can exacerbate hepatotoxicity. Patients with chronic liver disease should have baseline liver function tests and periodic monitoring.

FAQ

• Is Grisactin available in both brand‑name and generic forms in the UK?
  Yes. The original brand‑name versions such as Grifulvin V have been marketed historically, while generic Grisactin provides the same active ingredient, Griseofulvin, at a lower cost.

• Does Grisactin require any special storage conditions?
  The tablets should be kept at room temperature, between 15 °C and 30 °C, protected from moisture and direct sunlight. No refrigeration is needed.

• What does a Grisactin tablet look like?
  Grisactin tablets are round, typically white or off‑white, and bear a printed imprint identifying the manufacturer and dosage strength (e.g., “500 mg”).

• Can I travel with Grisactin on an international flight?
  Yes, provided you keep the medication in its original packaging, carry a copy of the prescription (if required by the destination country), and comply with the UK’s personal import allowances (up to 90 days’ supply).

• Are there any differences in inactive ingredients between UK‑produced and overseas Grisactin?
  In the UK formulation, common excipients include microcrystalline cellulose, lactose monohydrate, and magnesium stearate. Some overseas suppliers may use alternative fillers, but all are pharmaceutically approved and listed on the product label.

• Does taking Grisactin affect drug testing for employment or sports?
  Griseofulvin is not listed on standard doping panels, and it does not produce a positive result for common illicit substance screens. However, athletes should confirm with their governing body.

• What regulatory agency oversees Grisactin in the UK?
  The Medicines and Healthcare products Regulatory Agency (MHRA) is responsible for licensing, safety monitoring, and quality assurance of all medicines, including Grisactin, sold in the United Kingdom.

• Can Grisactin be used in patients with chronic kidney disease?
  Griseofulvin is partially excreted unchanged in urine; dose adjustment is not routinely required for mild to moderate renal impairment, but severe renal failure warrants careful monitoring and consultation with a renal specialist.

• How does Grisact as a treatment option compared with newer antifungals?
  While newer agents such as terbinafine have a shorter treatment duration, Griseofulvin remains useful for infections where cost is a major consideration or when contraindications to newer drugs exist. Its high keratin affinity is advantageous for nail infections.

• Is there any risk of developing resistance to Griseofulvin?
  Resistance is relatively rare but has been reported in some Trichophyton species after prolonged exposure. Proper dosing and adherence to the full treatment course minimise this risk.
