Toza 100 mg/5 ml Powder for Suspension
Toza 100 mg/5 ml Powder for Suspension Uses, Dosage, Side Effects, Food Interaction and all others data.
Toza 100 mg/5 ml Powder for Suspension, a synthetic antiprotozoal agent. Toza 100 mg/5 ml Powder for Suspension is well absorbed from GIT. It interferes with the Pyruvate Ferredoxin Oxidoreductase (PFOR) enzyme dependent electron transfer reaction which is essential to anaerobic glucose energy metabolism. This results in cell swelling, membrane damage resulting in dysfunction of the parasite.
The general effect of this medication is the prevention of microbe activity through disruption of important energy pathways for survival and proliferation . Toza 100 mg/5 ml Powder for Suspension exhibits antiprotozoal activity by interfering with the pyruvate ferredoxin/flavodoxin oxidoreductase dependent electron transfer reaction, an essential reaction need for anaerobic energy metabolism of various microorganisms. Sporozoites of Cryptosporidium parvum and trophozoites of Giardia lamblia are therefore inhibited, relieving symptoms of diahrrea . Interference with the PFOR enzyme-dependent electron transfer reaction may only be one of the many pathways by which nitazoxanide exhibits antiprotozoal activity .

How Toza 100 mg/5 ml Powder for Suspension works
The most widely accepted mechanism of NTZ is believed to be the disruption of the energy metabolism in anaerobic microbes by inhibition of the pyruvate: ferredoxin/flavodoxin oxidoreductase (PFOR) cycle . In parasitic-protozoa, Toza 100 mg/5 ml Powder for Suspension also induces lesions in the cell membranes and depolarizes the mitochondrial membrane while inhibiting quinone oxidoreductase NQO1, nitroreductase-1 and protein disulphide isomerase enzymes. In addition, this drug also inhibits the glutathione-S-transferase (a major detoxifying enzyme) and modulates the Avr-14 gene, encoding for the alpha-type subunit of glutamate-gated chloride ion channel present in nematodes. Aside from its well understood non-competitive inhibition of the PFOR in anaerobic bacteria, NTZ also demonstrates various other antibacterial mechanisms. It inhibits pyruvate dehydrogenase in E Coli, disrupts the membrane potential and pH homeostasis in the Mycobacterium tuberculosis, suppresses the chaperone/usher (CU) pathway of the gram-negative bacteria, and stimulates host macrophage autophagy in tuberculosis patients . NTZ also suppresses viral replication by inhibiting the maturation of the viral hemagglutinin and the viral transcription factor immediate early 2 (IE2) as well as by activating the eukaryotic translation initiation factor 2α (an antiviral intracellular protein). Lastly, NTZ exhibits an inhibitory effect on tumor cell progression by altering drug detoxification (glutathione-S-transferase P1), unfolded protein response, autophagy, anti-cytokines activity, and c-Myc inhibition .

Interaction
Toza 100 mg/5 ml Powder for Suspension is highly bound to plasma protein (>99.9%). Therefore, caution should be used when administering Toza 100 mg/5 ml Powder for Suspension concurrently with other highly plasma-protein bound drugs.
Food Interaction
- Take with food. Food improves oral bioavailability.
[Moderate] ADJUST DOSING INTERVAL: Food enhances the bioavailability of the pharmacologically active metabolite tizoxanide (desacetyl-nitazoxamide) from nitazoxanide administration.
According to the product labeling, administration of nitazoxanide tablets with food increases the area under the plasma concentration-time curve (AUC) of tizoxanide and tizoxanide glucuronide in plasma by almost 2-fold and the peak plasma concentration (Cmax) by almost 50%.
