Biochem/physiol Actions

Tizoxanide (TIZ) is the active metabolite of the broad-spectrum parasiticidal drug nitazoxanide (NTZ), a noncompetitive inhibitor against bacterial pyruvate-ferredoxin oxidoreductase (PFOR Ki 2 to 10 μM). NTZ deacetylates rapidly to TIZ in plasma (t1/2 ~6 min at 37°C in human plasma) and in the presence of liver microsomes. NTZ is also reported to exhibit antiviral activity against Hepatitis C, Norovirus, Paramyxovirus, Influenza, Vaccinia, and Zika.

F Mégraud et al.
Antimicrobial agents and chemotherapy, 42(11), 2836-2840 (1998-10-31)
Nitazoxanide, a thiazolide compound, and its desacetyl derivative, tizoxanide, have antimicrobial properties against anaerobic bacteria, as well as against helminths and protozoa. Because the treatment of Helicobacter pylori infection may be jeopardized by metronidazole resistance, nitazoxanide and tizoxanide were tested
Y Yamamoto et al.
Chemotherapy, 45(4), 303-312 (1999-07-08)
Nitazoxanide (NTZ), a synthesized drug of the nitrothiazolide class, was initially developed as an antiparasitic compound. This compound has recently been shown to have antibacterial activities against some bacterial pathogens. In the present study, NTZ and its main metabolite tizoxanide
L Dubreuil et al.
Antimicrobial agents and chemotherapy, 40(10), 2266-2270 (1996-10-01)
The antibacterial activities of nitazoxanide and its main metabolite, tizoxanide, were tested against a broad range of bacteria, including anaerobes. Metronidazole, amoxicillin, amoxicillin-clavulanic acid, piperacillin, cefoxitin, imipenem, and clindamycin were used as positive controls. MICs were determined by reference agar
J Broekhuysen et al.
International journal of clinical pharmacology and therapeutics, 38(8), 387-394 (2000-09-13)
Nitazoxanide (N), a new broad-spectrum parasiticidal agent, is rapidly deacetylated to tizoxanide (T). The objective of the study was to determine if metabolites other than T are present in the plasma and excreted after single dose oral administration of radiocarbon-labelled
A Stockis et al.
International journal of clinical pharmacology and therapeutics, 40(5), 213-220 (2002-06-08)
Nitazoxanide (N) is a new broad-spectrum intestinal antiparasitic agent. Deacetyl-N or tizoxanide (T) and its glucuronide (TG) are the major circulating species metabolites after oral administration of N. Bioavailability is substantially increased by food. The objectives of this phase IA
