Metronidazol Altan (Metronidazole)

Metronidazol Altan is employed to manage infections caused by anaerobic microorganisms and certain protozoa.

• Intra‑abdominal infections: eliminates anaerobic bacteria and supports recovery after surgery or perforation.
• Pelvic inflammatory disease: eradicates causative anaerobes and improves pelvic health.
• Bacterial sepsis caused by susceptible anaerobes: provides rapid systemic antimicrobial action.
• Skin and soft‑tissue infections with anaerobic involvement: reduces bacterial load and promotes wound healing.
• Bone and joint infections (osteomyelitis) with anaerobic pathogens: assists in infection control and tissue repair.

• Metronidazole is reduced inside anaerobic microorganisms, generating reactive nitro radicals that damage DNA and inhibit nucleic acid synthesis. This leads to strand breakage and bacterial or protozoal cell death, while aerobic cells remain largely unaffected due to the lack of reduction.

Metronidazol Altan may cause a range of adverse reactions, most of which are dose‑related and reversible upon discontinuation.

Common Side Effects

• Nausea: mild to moderate upset stomach.
• Metallic taste: transient metallic sensation in the mouth.
• Headache: mild to moderate cephalgia.
• Diarrhea: loose stools, usually self‑limiting.
• Abdominal pain: cramping or discomfort.
• Dizziness: occasional light‑headedness.

Serious or Rare Side Effects

• Seizures: rare neurologic events, especially with high doses.
• Peripheral neuropathy: tingling or numbness in extremities.
• Stevens‑Johnson syndrome: severe skin reactions.
• Anaphylaxis: acute allergic response requiring emergency care.
• Hepatic toxicity: elevated liver enzymes or hepatitis.
• Severe neutropenia: marked reduction in white blood cells.

Metronidazol Altan requires careful consideration of patient‑specific factors and proper handling to ensure safety.

• Renal impairment: adjust dose or monitor renal function closely.
• Hepatic dysfunction: use with caution; monitor liver enzymes.
• Alcohol consumption: avoid due to disulfiram‑like reaction.
• Hematologic disorders: watch for neutropenia or thrombocytopenia.
• Pregnancy and breastfeeding: assess risk‑benefit; limited data available.
• Store at ambient temperature: keep in original container, protect from moisture and light.

Metronidazol Altan can influence or be influenced by several concomitant medicines.

Major Interactions (Avoid)

• Alcohol: may cause severe flushing, tachycardia, and hypotension.
• Warfarin: potentiates anticoagulant effect, increasing bleeding risk.
• Lithium: may raise lithium serum levels, leading to toxicity.
• Carbamazepine: reduces metronidazole concentrations, diminishing efficacy.

Moderate Interactions (Monitor Closely)

• Phenytoin: may lower metronidazole levels; monitor therapeutic response.
• Phenobarbital: similar enzyme‑inducing effect as phenytoin.
• Rifampin: decreases metronidazole exposure; adjust dose if needed.
• Oral contraceptives: may reduce hormonal efficacy; advise additional contraception.
• Cyclosporine: can increase cyclosporine concentrations; monitor renal function.
