Metrosa

Metronidazole, the active ingredient in Metrosa, is a nitroimidazole antibiotic presented as a topical formulation for cutaneous use. It is employed to manage certain inflammatory skin conditions such as acne vulgaris and rosacea. GNH USA supplies Metrosa as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Metrosa, a nitroimidazole antibiotic, is applied to skin disorders where bacterial or protozoal involvement contributes to inflammation. - Acne vulgaris: reduces inflammatory lesions and bacterial colonisation on the skin. - Rosacea: diminishes papules, pustules and erythema associated with the condition. - Skin infections (e.g., susceptible bacterial or protozoal lesions): limits microbial growth and alleviates local inflammation.

Metrosa may cause local and systemic adverse reactions.

Common Side Effects: - Skin irritation: mild burning or stinging at the application site. - Dryness: increased transepidermal water loss causing flaky skin. - Itching: pruritus localized to treated areas. - Redness: transient erythema after application. - Allergic contact dermatitis: localized rash with swelling. - Peeling: desquamation of the outer skin layer.

Serious or Rare Side Effects: - Anaphylaxis: severe, systemic allergic reaction requiring emergency care. - Stevens‑Johnson syndrome or toxic epidermal necrolysis: extensive skin detachment. - Severe photosensitivity: exaggerated sunburn response. - Neurotoxicity: peripheral neuropathy or seizures with systemic absorption. - Hemolytic anemia in patients with G6PD deficiency. - Severe systemic infection: rare but possible if absorption is high.

Before using Metrosa, consider the following safety measures. - Pregnancy: consult a prescriber; safety data are limited. - Breastfeeding: use with caution; metronidazole may be excreted in milk. - Skin integrity: avoid application on open wounds or severely damaged skin. - Alcohol consumption: limit intake to reduce risk of disulfiram‑like reactions. - Hypersensitivity: discontinue immediately if signs of allergic reaction appear. - Store at below 25°C: keep in the original container, protect from moisture and light.

Metrosa can interact with other substances; monitor as indicated.

Major Interactions (Avoid): - Alcohol: may provoke a disulfiram‑like reaction with flushing and nausea. - Warfarin: can potentiate anticoagulant effects, increasing bleeding risk. - Lithium: concurrent use may heighten neurotoxic potential.

Moderate Interactions (Monitor Closely): - Cimetidine: may raise metronidazole plasma concentrations. - Phenobarbital: can reduce metronidazole efficacy through enzyme induction. - Oral contraceptives: possible reduction in hormonal effectiveness; consider backup contraception.
