Pharmacokinetics

AbsorptionNitazoxanide: Well absorbed orally; Ofloxacin: Well absorbed orally
DistributionNitazoxanide: Widely distributed; Ofloxacin: Widely distributed, high tissue penetration
Protein BindingNitazoxanide: >99% (to albumin); Ofloxacin: 20-32%
MetabolismNitazoxanide: Hydrolyzed to active metabolite tizoxanide; Ofloxacin: Minimally metabolized (hepatic)
Half-LifeNitazoxanide: 1-1.5 hours (tizoxanide: 7-8 hours); Ofloxacin: 4-5 hours
ExcretionNitazoxanide: Renal (tizoxanide) and fecal; Ofloxacin: Renal (80-90% unchanged)
BioavailabilityNitazoxanide: ~70%; Ofloxacin: ~98%
Onset of ActionNitazoxanide: Rapid; Ofloxacin: 1-2 hours
Peak Plasma TimeNitazoxanide: 1-4 hours (tizoxanide); Ofloxacin: 1-2 hours
Duration of ActionNitazoxanide: 12-24 hours; Ofloxacin: 12-24 hours

How It Works

Nitazoxanide: Interferes with pyruvate:ferredoxin oxidoreductase (PFOR) enzyme-dependent electron transfer reaction, inhibiting anaerobic metabolism; Ofloxacin: Inhibits DNA gyrase and topoisomerase IV, preventing bacterial DNA replication

Mechanism Steps

1Nitazoxanide is hydrolyzed to active metabolite tizoxanide
2Tizoxanide inhibits pyruvate:ferredoxin oxidoreductase (PFOR) enzyme in anaerobic organisms
3Inhibition of PFOR disrupts anaerobic energy metabolism, leading to cell death
