Areas to be treated should be cleansed before application of metronidazole gel USP (topical), 0.75%. Patients may use cosmetics after application of metronidazole gel USP (topical), 0.75%.

The following adverse experiences have been reported with the topical use of metronidazole: burning, skin irritation, dryness, transient redness, metallic taste, tingling or numbness of extremities and nausea.

Oral metronidazole has been reported to potentiate the anticoagulant effect of coumarin and warfarin resulting in a prolongation of prothrombin time. The effect of topical metronidazole on prothrombin time is not known.

Metronidazole gel USP (topical), 0.75%, contains metronidazole, at a concentration of 7.5 mg per gram (0.75%) in a gel consisting of carbopol 980, edetate disodium, methylparaben, propylene glycol, propylparaben, purified water, and sodium hydroxide. Metronidazole is classified therapeutically as an antiprotozoal and anti-bacterial agent. Chemically, metronidazole is named 2-methyl-5-nitro-1H-imidazole-1- ethanol and has the following structure:

Bioavailability studies on the topical administration of 1 gram of metronidazole gel USP (topical), 0.75%, (7.5 mg of metronidazole) to the face of 10 rosacea patients showed a maximum serum concentration of 66 nanograms per milliliter in one patient. This concentration is approximately 100 times less than concentrations afforded by a single 250 mg 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 had no detectable serum concentrations of metronidazole at any time point. The mean dose of gel applied during clinical studies was 600 mg which represents 4.5 mg of metronidazole per application. Therefore, under normal usage levels, the formulation affords minimal serum concentrations of metronidazole. The mechanisms by which metronidazole gel USP (topical), 0.75%, acts in the treatment of rosacea are unknown, but appear to include an anti-inflammatory effect.
