🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionNitazoxanide is rapidly absorbed from the gastrointestinal tract after oral administration and is hydrolyzed to its active metabolite, tizoxanide. Ofloxacin is well absorbed orally, with bioavailability approaching 95-100%.
DistributionTizoxanide is highly protein-bound and distributes widely into body tissues and fluids. Ofloxacin distributes widely into most body tissues and fluids, including lung, kidney, prostate, and bile.
Protein BindingTizoxanide is approximately 99% protein-bound. Ofloxacin is approximately 20-30% protein-bound.
MetabolismNitazoxanide is rapidly hydrolyzed to tizoxanide, which undergoes glucuronidation and renal excretion. Ofloxacin is minimally metabolized in the liver, with less than 10% metabolized.
Half-LifeThe elimination half-life of tizoxanide is approximately 1.5 hours. The elimination half-life of ofloxacin is approximately 4-5 hours in adults with normal renal function.
ExcretionTizoxanide and its metabolites are excreted primarily in urine and feces. Ofloxacin is excreted largely unchanged in urine (70-80%) and feces (20%).
BioavailabilityNitazoxanide oral bioavailability is approximately 70% as tizoxanide. Ofloxacin oral bioavailability is approximately 95-100%.
Onset of ActionOnset of action for nitazoxanide is within 1-2 hours after oral administration. Ofloxacin onset is also within 1-2 hours.
Peak Plasma TimePeak plasma concentration of tizoxanide is reached in about 1-2 hours. Peak plasma concentration of ofloxacin is reached in about 1-2 hours.
Duration of ActionThe duration of action for nitazoxanide is approximately 12 hours. For ofloxacin, it is approximately 12-24 hours depending on the dose and renal function.

How It Works

This medicine combines two active ingredients with distinct mechanisms. Nitazoxanide is a thiazolide antiprotozoal that inhibits pyruvate:ferredoxin oxidoreductase (PFOR), an enzyme essential for anaerobic energy metabolism in protozoa and anaerobic bacteria. This disrupts their energy production and leads to cell death. Ofloxacin is a fluoroquinolone antibiotic that inhibits bacterial DNA gyrase and topoisomerase IV, enzymes required for DNA replication, transcription, repair, and recombination. This leads to inhibition of bacterial DNA synthesis and cell death. The combination provides broad coverage against both protozoal and bacterial pathogens.

Mechanism Steps

1
Nitazoxanide uptake and activation: Nitazoxanide is taken up by protozoal and anaerobic bacterial cells and is rapidly metabolized to its active form, tizoxanide.
2
Inhibition of PFOR: Tizoxanide inhibits pyruvate:ferredoxin oxidoreductase, blocking electron transfer and ATP production in anaerobic organisms.
3
Ofloxacin entry into bacteria: Ofloxacin penetrates bacterial cell walls and binds to DNA gyrase and topoisomerase IV.
4
Inhibition of DNA replication: Ofloxacin prevents DNA supercoiling and replication, leading to bacterial cell death.

💡 How to Take nixide o tablet

Strength: Each tablet contains Nitazoxanide 500 mg and Ofloxacin 200 mg.

1Take this medicine orally with a full glass of water.
2Swallow the tablet whole. Do not crush, chew, or break it.
3Take it with food to reduce stomach upset.
4Do not take antacids, iron, or zinc supplements within 2 hours of this medicine.

6If you miss a dose, follow the missed dose instructions.

Dosage Information

Adult DosageThe usual adult dose of this medicine is one tablet taken orally twice daily, preferably with food. The exact dose and duration depend on the type and severity of the infection, your age, weight, kidney and liver function, and your response to treatment. 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.
Elderly DosageElderly patients may be more sensitive to the side effects of this medicine, especially dizziness, tendon problems, and kidney-related effects. Dose adjustment may be necessary based on renal function. Consult your doctor for appropriate dosing.
Renal ImpairmentIn patients with renal impairment, dose adjustment of ofloxacin is required. For creatinine clearance between 20-50 mL/min, the usual dose may be reduced or the dosing interval extended. For creatinine clearance less than 20 mL/min, further dose reduction is needed. Nitazoxanide does not require dose adjustment in renal impairment. Consult your doctor for personalized dosing.
Hepatic ImpairmentNo specific dose adjustment is established for nitazoxanide in hepatic impairment. Ofloxacin is minimally metabolized in the liver, so dose adjustment is generally not required for mild to moderate hepatic impairment. Use with caution in severe hepatic impairment. Consult your doctor.
Maximum Daily DoseThe maximum recommended daily dose is one tablet twice daily (total 1000 mg nitazoxanide and 400 mg ofloxacin). Do not exceed this dose unless specifically instructed by your doctor.
