Metronidazol Braun (Metronidazole)

Metronidazol Braun, a nitroimidazole antibiotic, is indicated for several anaerobic and protozoal infections.

• Anaerobic bacterial infections: effective in treating infections caused by anaerobic organisms such as intra‑abdominal and pelvic infections.
• Bacterial vaginosis: restores normal vaginal flora by eliminating Gardnerella and related anaerobes.
• Trichomoniasis: eradicates Trichomonas vaginalis in genital infections.
• Amebic liver abscess: resolves hepatic lesions caused by Entamoeba histolytica.
• Clostridioides difficile infection: reduces toxin‑producing C. difficile in the colon.

• Metronidazole is reduced inside anaerobic microorganisms by electron‑transport proteins, generating nitro radicals that bind to DNA. These reactive intermediates cause strand breakage and inhibit nucleic acid synthesis, leading to bacterial and protozoal cell death while sparing aerobic cells. The selective activation occurs under low redox potential conditions typical of anaerobic environments, confining its antimicrobial activity to target organisms.

Metronidazol Braun may cause a range of adverse reactions, varying from mild to severe.

Common Side Effects

• Nausea: mild to moderate upset stomach.
• Headache: transient cranial discomfort.
• Diarrhea: loose stools during therapy.
• Metallic taste: transient alteration of taste perception.

Serious or Rare Side Effects

• Seizures: rare neurologic events requiring immediate attention.
• Peripheral neuropathy: tingling or numbness in extremities.
• Stevens‑Johnson syndrome: severe skin and mucosal reactions.
• Anaphylaxis: acute allergic response with respiratory compromise.
• Severe neutropenia: marked reduction in white blood cells.

When prescribing Metronidazol Braun, clinicians should consider several safety considerations.

• Renal impairment: adjust therapy in patients with reduced kidney function.
• Hepatic impairment: monitor liver enzymes and consider dose modification.
• Alcohol consumption: avoid alcohol to prevent disulfiram‑like reactions.
• Pregnancy: use only if clearly needed, as safety data are limited.
• Lactation: assess risk versus benefit before use while breastfeeding.
• Store at room temperature: keep in original container, protect from light and moisture.

Metronidazol Braun can interact with other medicines, requiring careful management.

Major Interactions (Avoid)

• Alcohol: may cause severe disulfiram‑like reaction.
• Warfarin: potentiates anticoagulant effect, increasing bleeding risk.
• Lithium: may raise lithium levels, leading to toxicity.

Moderate Interactions (Monitor Closely)

• Phenytoin: may reduce metronidazole concentrations.
• Cimetidine: can increase metronidazole plasma levels.
• Carbamazepine: may lower metronidazole effectiveness.
