To study the effects of SKF-525A, an inhibitor of cytochrome P-450, and of sodium phenobarbital (PB), a drug-metabolizing enzyme inducer, on the teratogenicity of thiabendazole (TBZ), pregnant mice were given ip either a single dose of 40 mg SKF-525A/kg 1 hr before oral dosing with 250 or 500 mg TBZ/kg or a dose of 75 mg PB/kg/day on three consecutive days before oral administration of a dose of 500 or 1000 mg TBZ/kg.

The effect of sulfur-containing benzimidazoles (thiabendazole, 5-hydroxy-thiabendazole, cambendazole) and sulfur-free derivatives (benzimidazole, carbendazim and 5-hydroxycarbendazim) on cytochrome P450 enzymes was investigated in primary cultures of rabbit hepatocytes considered 72 h after plating.

In order to characterize precisely the cytochrome P450 isozyme (s) involved in its major route of metabolism, a rapid and sensitive spectrofluorimetric method was developed for the simultaneous determination of thiabendazole and its main hepatic metabolite 5-hydroxythiabendazole. 2.

In experiments carried out in vitro, the binding of [14C] thiabendazole to microsomal protein of the liver was proportional to time and protein concentration, was dependent upon the presence of oxygen and NADPH and was inhibited by carbon monoxide or SKF-525A, indicating that it was mediated by the cytochrome P-450-dependent monooxygenase system.

Using the CL (H) predicted from the in vitro data, the compounds could be classified into three different categories: high-clearance drugs (> 70% liver blood flow; amodiaquine, praziquantel, albendazole, thiabendazole), low-clearance drugs (<30% liver blood flow; chloroquine, dapsone, diethylcarbamazine, pentamidine, primaquine, pyrantel, pyrimethamine, tinidazole) and intermediate clearance drugs (artemisinin, artesunate, quinine).

Treatment with three inhibitors of renal microsomal cytochrome P-450-dependent monooxygenases, piperonyl butoxide, methoxsalen and carbon disulphide, all equally prevented the nephrotoxicity of TBZ given in combination with BSO.

Conversely, thiabendazole (TBZ) and fenbendazole (FBZ) did not affect the oxidative metabolism of both incubated substrates.
TCBZ sulphoxidative metabolism was also reduced (24% inhibition, P < 0.05) by the cytochrome P450 inhibitor piperonyl butoxide (PB).

Moreover, the protein-bound residues in these cells, which could be related to cytochrome P450-dependent oxidation, were formed in 4 times greater amounts than in the other animal cells.

Drug Metab Dispos. 2006 Aug;34(8):1376-85. Epub 2006 May 19.

Cytochrome P450 (P450) enzymes metabolize the membrane lipid arachidonic acid to stable biologically active epoxides [eicosatrienoic acids (EETs)] and 20-hydroxyeicosatetraenoic acid (20-HETE).
We report here that imidazole derivative drugs: the anthelminthics, albendazole and thiabendazole; the proton pump inhibitor, omeprazole; the thromboxane synthase inhibitor, benzylimidazole; and the aromatase (CYP19) inhibitor vorozole (R76713, racemate; and R83842, (+) enantiomer) increased hepatic microsomal EET formation in a chick embryo model.

Many drugs have been found to increase or decrease the clearance of theophylline, probably by interaction with one or more of the variants of the cytochrome P450 drug-metabolising system.
Its clearance has been found to be decreased (typically by around 25%, but often by far more) by erythromycin, troleandomycin (triacetyloleandomycin), roxithromycin, enoxacin, ciprofloxacin, pefloxacin, norfloxacin, ofloxacin, fluoroquinolone T-3262, pipemidic acid, cimetidine, etintidine, propranolol, verapamil, diltiazem, nifedipine, furosemide (frusemide), at least some anovulent agents, viloxazine, allopurinol, ticlopidine, idrocilamide, thiabendazole, disulfiram, influenza- and BCG-vaccination, interferon, and caffeine (half-life increase).

At the highest concentrations and without apparent cellular toxicity, the drug provokes a dose-dependent increase in total microsomal cytochrome P450 and a rise in EROD activity which was correlated to a specific increase in P4501A1 level.

Furthermore, continuous exposure to 540 ug/l thiabendazole [2-(thiazol-4'-yl) benzimidazole] in a flow-through system for 4 days significantly increased the gill glutathione S-transferase (GST) activity towards CDNB, whilst hepatic GST and cytochrome P450 (CYP 1A) activities were not increased by the treatment.

Second, infection of lambs by H contortus may have triggered an inductive response in hepatic cytochrome P-450-mediated activities, which might result via a generalized enhancement in hepatic protein synthesis associated with the physiologic response to replace plasma proteins and other blood components lost through gastrointestinal hemorrhage caused by the active feeding of adult worms.
Clearance of antipyrine was enhanced by the infection, and thiabendazole treatment did not alter this effect.
