Metrogalen

Metronidazole, the active ingredient in Metrogalen, is a nitroimidazole antibiotic presented as a topical formulation for cutaneous use. It treats bacterial skin infections and certain protozoal conditions, such as rosacea and acne vulgaris, in adult patients.

GNH USA supplies Metrogalen as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The product meets European Union quality standards and is manufactured under GMP conditions.

Metronidazole is a nitroimidazole antibiotic used topically to manage bacterial and protozoal skin disorders.

- Rosacea: reduces inflammatory lesions and erythema associated with the condition. - Acne vulgaris: decreases acne lesions by targeting anaerobic bacteria and reducing inflammation. - Bacterial skin infections: treats localized infections such as impetigo and folliculitis by eradicating susceptible organisms.

Topical metronidazole may cause local and systemic adverse reactions, which are categorized by frequency and severity.

Common Side Effects: - Skin irritation: mild redness, burning, or stinging at the application site. - Dryness: localized dryness or flaking of the treated skin. - Pruritus: itching sensation that may accompany irritation. - Contact dermatitis: allergic skin reaction presenting as rash or swelling.

Serious or Rare Side Effects: - Severe allergic reaction: anaphylaxis, angioedema, or widespread urticaria. - Stevens‑Johnson syndrome: rare severe mucocutaneous reaction. - Systemic toxicity: rare systemic absorption leading to neurotoxicity or hepatic effects.

When using Metrogalen, consider the following safety measures.

- Limit application area: apply only to the prescribed skin region to minimize systemic absorption. - Avoid broken skin: do not apply on open wounds or extensive dermatitis. - Monitor for allergy: discontinue use if signs of hypersensitivity develop. - Pregnancy and lactation: use only if clearly indicated and prescribed by a healthcare professional. - Interactions with alcohol: advise patients to avoid alcohol consumption to reduce risk of disulfiram‑like reactions. - Store below 25°C: keep in the original container, protect from moisture and light.

Metronidazole can interact with other substances; awareness of the interaction level helps guide safe use.

Major Interactions (Avoid): - Alcohol: concurrent intake may cause a disulfiram‑like reaction with flushing, nausea, and tachycardia. - Warfarin: may potentiate anticoagulant effect, increasing bleeding risk.

Moderate Interactions (Monitor Closely): - Lithium: concurrent use may increase lithium levels; monitor serum concentrations. - Cytochrome P450 inducers (e.g., rifampicin, carbamazepine): may reduce metronidazole efficacy. - Other topical antibiotics: concurrent use may increase local irritation; assess skin tolerance.
