Its exact mechanism of action has not been entirely determined as yet. It has been proposed that an intermediate in the reduction of metronidazole, produced only in anaerobic bacteria and protozoa is bound to deoxyribonucleic acid and electron-transport proteins, inhibits subsequent nucleic acid synthesis. At present, the mechanism by which topical metronidazole reduces the lesions and erythema associated with acne rosacea is not precisely known. Despite the established antimicrobial effects of metronidazole, there is no evidence that the suppression of bacteria or parasitic mites harbored in the skin is directly responsible for its beneficial effects in rosacea. _In vitro_ and _in _ _vivo_ studies indicate that metronidazole has direct antiinflammatory activity and affects neutrophil chemotaxis and cell-mediated immunity. An antioxidant action via inhibition of neutrophil-generated reactive oxygen species has also been demonstrated; this action is believed to underlie its antiinflammatory effect. It has been proposed that the reduction in rosacea lesions and erythema is the result of antiinflammatory or immunosuppressive actions of metronidazole. Nystatin is an antifungal antibiotic, produced by a strain of _Streptomyces noursei_, active against yeasts and yeast like fungi, including Candida albicans. The antifungal activity is probably due to the binding of Lees het volledige document
