2
Advise patients to take the suspension with food to minimize gastrointestinal upset.
3
Warn patients strictly against alcohol consumption during and for 48 hours after treatment.
4
Instruct patients to separate antacids, iron, or zinc supplements by at least 2 hours from this medicine.

🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionMetronidazole is rapidly and almost completely absorbed from the gastrointestinal tract after oral administration. Norfloxacin is absorbed moderately, with bioavailability of about 30-40%, and absorption is reduced by food, antacids, and metal ions.
DistributionMetronidazole distributes widely into body tissues and fluids, including cerebrospinal fluid, saliva, breast milk, and crosses the placenta. Norfloxacin distributes into kidney, prostate, and bile, but has limited penetration into cerebrospinal fluid.
Protein BindingMetronidazole is less than 20% bound to plasma proteins. Norfloxacin is approximately 10-15% bound to plasma proteins.
MetabolismMetronidazole is metabolized in the liver by cytochrome P450 enzymes, primarily CYP2C9, to hydroxy and acid metabolites. Norfloxacin undergoes limited hepatic metabolism.
Half-LifeMetronidazole half-life is approximately 6-8 hours in adults with normal renal and hepatic function. Norfloxacin half-life is approximately 3-4 hours.
ExcretionMetronidazole and its metabolites are excreted mainly in urine (60-80%) and feces (6-15%). Norfloxacin is excreted primarily unchanged in urine (up to 30%) and bile.
BioavailabilityMetronidazole oral bioavailability is nearly 100%. Norfloxacin oral bioavailability is approximately 30-40%.
Onset of ActionAntibacterial effects begin within 1-2 hours after oral administration, but clinical improvement may take 24-48 hours.
Peak Plasma TimeMetronidazole peak plasma concentration occurs 1-2 hours after oral dose. Norfloxacin peak plasma concentration occurs 1-2 hours after oral dose.
Duration of ActionThe antimicrobial effect persists for approximately 8-12 hours for metronidazole and 6-8 hours for norfloxacin, depending on the dose and susceptibility of the organism.

How It Works

This medicine combines two antibiotics with different mechanisms. Metronidazole enters anaerobic organisms and protozoa, where its nitro group is reduced to reactive intermediates that damage DNA and inhibit nucleic acid synthesis, leading to cell death. Norfloxacin inhibits DNA gyrase and topoisomerase IV, enzymes essential for bacterial DNA replication, repair, and transcription, thereby stopping bacterial growth and causing cell death. Together, they cover a broader spectrum of bacteria and parasites than either agent alone.

Mechanism Steps

1
Metronidazole uptake and activation: Metronidazole diffuses into anaerobic bacteria and protozoa, where its nitro group is reduced by ferredoxin-like electron transport proteins.
2
DNA damage by metronidazole: The reduced metronidazole forms reactive radicals that bind to DNA, causing strand breakage and inhibiting nucleic acid synthesis.
3
Norfloxacin binding to DNA gyrase: Norfloxacin binds to the DNA gyrase enzyme complex, stabilizing the enzyme-DNA cleavage complex and blocking DNA replication.
4
Inhibition of topoisomerase IV: Norfloxacin also inhibits topoisomerase IV, preventing separation of daughter DNA strands and causing bacterial cell death.
5
Combined antimicrobial effect: The two mechanisms act on different targets, providing broad coverage against mixed aerobic and anaerobic infections.

Dosage Information

Adult DosageThe usual adult dose of this medicine is 5 mL to 10 mL (providing 100 mg metronidazole and 100 mg norfloxacin per 5 mL) taken orally every 12 hours, or as directed by your doctor. The exact dose and duration depend on the type and severity of infection, your kidney and liver function, and your overall health. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. Do not self-adjust the dose. Complete the full course as prescribed.
Pediatric DosagePediatric dosing is not established from available information. Consult a pediatrician. Norfloxacin is generally not recommended in children under 18 years due to potential risk of cartilage and tendon damage.
Elderly DosageElderly patients may be more sensitive to the side effects of this medicine, especially tendon rupture, kidney problems, and neurological effects. Dose adjustment may be needed based on kidney function. Use with caution and monitor closely.
Renal ImpairmentIn patients with reduced kidney function, dose adjustment is required, especially for the norfloxacin component. Consult your doctor for appropriate dosing. Monitoring of renal function is recommended.
Hepatic ImpairmentIn patients with liver disease, metronidazole dose may need to be reduced. Norfloxacin also requires caution. Consult your doctor for appropriate dosing and monitoring.
Maximum Daily DoseThe maximum daily dose should not exceed 400 mg metronidazole and 400 mg norfloxacin, or as prescribed by your doctor. Do not exceed the recommended dose.
