Full Prescribing Info
Contents
Metronidazole.
Description
Each gram of gel contains: Metronidazole 10 mg.
Excipients/Inactive Ingredients: Preservatives: Methyl Paraben 0.032% w/w, Propyl Paraben 0.04% w/w, Water soluble gel base q.s.
Action
Pharmacology: Pharmacodynamics: Metronidazole is an effective, broad-spectrum antiprotozoal and antibacterial drug from the group of nitroimidazole. It is effective for the clinical treatment of patients with pyro-inflammatory diseases.
Pharmacokinetics: Bioavailability studies on the topical administration of 1 gram of Metronidazole of gel to face of 10 rosacea patients showed a maximum serum concentration of 66 nanograms per mililiter in one patient. This concentration is approximately 100 times less than concentration afforded by a single 250mg oral tablet. The serum metronidazole concentrations were below the detectable limits of the assay at the majority of time points in all patients. Three of the patients detectable serum concentration of metronidazole at any time point. The mean dose of gel applied during clinical studies was 600mg which represents 4.5mg of metronidazole per application. Therefore, under normal usage levels, the formulation affords minimal serum concentration of metronidazole.
Indications/Uses
Metrogyl Gel is indicated for topical application in the treatment of inflammatory papules, pustules and erythema of rosacea.
Dosage/Direction for Use
Apply and rub in a thin film of metrogyl gel twice daily, morning and evening to entire affected areas after washing. Significant therapeutic results should be noticed within three weeks. Clinical studies have demonstrated continuing improvement through nine weeks of therapy.
Overdosage
Not reported.
Contraindications
Metrogyl Gel is contraindicated in individuals with a history of hypersensitivity to metronidazole.
Special Precautions
Because of the minimum absorption of metronidazole and consequently its insignificant plasma concentration after topical administration, the adverse experiences reported with oral form of the drug have not been reported with metrogyl gel.
Information for the Patients: This medication is to be used as directed by the Physician. It is for external use only. Avoid contact with the eyes.
Use In Pregnancy & Lactation
The safety of topically applied metronidazole in pregnancy and lactation has not been adequately established. It should be used only if clearly needed.
Adverse Reactions
Adverse conditions reported include watery (tearing) eyes, if the gel is applied too closely to this area, transient redness, and mild dryness, burning and skin irritation. None of the side effect exceeded an incidence of 2% of patients.
Drug Interactions
Drug Interactions are less likely with topical administration but should be kept in mind when metrogyl gel is prescribed for patients who are receiving anticoagulant treatment. Oral metronidazole has been reported to potentiate the anticoagulant effect of coumarin and warfarin resulting in a prolongation of prothrombin time.
Storage
Store in a cool place, below 30°C. Protect from light.
Shelf-Life: 36 months from the date of manufacture.
