Metronidazol Viaflo Baxter (Metronidazole)

Metronidazole is employed for infections where anaerobic bacteria play a key pathogenic role.

• Intra‑abdominal infections: eradicates mixed aerobic‑anaerobic flora to control peritonitis and postoperative sepsis.
• Bacterial sepsis due to anaerobes: provides rapid systemic coverage in critically ill patients.
• Pelvic inflammatory disease: eliminates anaerobic organisms responsible for tubo‑ovarian abscesses.
• Bacterial meningitis (anaerobic etiology): penetrates the cerebrospinal fluid to treat resistant strains.
• Necrotizing skin and soft‑tissue infections: targets deep‑seated anaerobes in fasciitis and gangrene.

• Metronidazole is reduced within susceptible microorganisms, generating reactive nitro radicals that damage DNA and inhibit nucleic acid synthesis. This leads to strand breakage and cell death, selectively affecting anaerobic bacteria and protozoa while sparing most human cells.

Metronidazole may cause a range of adverse reactions.

Common Side Effects

• Nausea: mild to moderate upset stomach.
• Metallic taste: transient metallic sensation in the mouth.
• Headache: occasional dull or throbbing pain.
• Diarrhoea: loose stools, sometimes watery.
• Abdominal pain: cramping or discomfort.
• Rash: mild skin erythema or itching.

Serious or Rare Side Effects

• Seizures: neurologic events requiring immediate care.
• Peripheral neuropathy: tingling or numbness in extremities.
• Stevens‑Johnson syndrome: severe skin blistering and mucosal involvement.
• Anaphylaxis: acute allergic reaction with airway compromise.
• Hepatotoxicity: elevated liver enzymes or jaundice.
• Blood dyscrasias: neutropenia, thrombocytopenia, or aplastic anaemia.

Metronidazol Viaflo Baxter requires careful clinical consideration.

• Renal impairment: adjust dosing in patients with reduced kidney function.
• Hepatic dysfunction: monitor liver enzymes and consider dose modification.
• Alcohol consumption: avoid due to disulfiram‑like reaction causing flushing and tachycardia.
• Pregnancy: category unknown; use only if potential benefit outweighs risk.
• Neonates: avoid in premature infants because of reduced metabolic capacity.
• Store at ambient temperature: keep in original container, protect from light and moisture.

Metronidazol Viaflo Baxter can interact with several medicines.

Major Interactions (Avoid)

• Alcohol: may cause severe disulfiram‑like reaction.
• Warfarin: potentiates anticoagulant effect, increasing bleeding risk.
• Lithium: can raise lithium serum levels, leading to toxicity.
• Cyclosporine: may increase cyclosporine concentrations.
• Phenytoin: reduces metronidazole levels, compromising efficacy.

Moderate Interactions (Monitor Closely)

• Cimetidine: may increase metronidazole plasma concentration.
• Oral contraceptives: possible reduction in contraceptive effectiveness.
• Carbamazepine: may lower metronidazole levels.
• Rifampin: can decrease metronidazole exposure.
• Theophylline: may raise theophylline levels, requiring monitoring.
