Targets:
Conditions:
Fomepizole (4-methylpyrazole) is a competitive ADH inhibitor. Fomepizole has been shown in vitro to block alcohol dehydrogenase enzyme activity in dog, monkey and human liver. Fomepizole is indicated as an antidote for ethylene glycol (such as antifreeze) or methanol poisoning, or for use in suspected ethylene glycol or methanol ingestion, either alone or in combination with hemodialysis. It should be given when a known or suspected toxic ethylene glycol or methanol ingestion has occurred and the patient has metabolic acidosis and elevated osmolar gap. The most frequent adverse events reported as drug-related or unknown relationship were headache (14%), nausea (11%), and dizziness, increased drowsiness, and bad taste/metallic taste. Reciprocal interactions may occur with concomitant use of fomepizole and drugs that increase or inhibit the cytochrome P450 system (e.g. phenytoin, carbamazepine, cimetidine, ketoconazole). Fomepizole has been shown to induce the expression of CYP2E1 and to inhibit its activity. These effects were enhanced in rats that had been exposed to ethanol. Fomepizole may also inhibit other CYP enzymes and therefore may alter the exposure to other drugs that are metabolised by CYP enzymes.

Sodium thiosulfate (sodium thiosulphate/STS) is a chemical and medication. As a medication, it is used in combination with sodium nitrite under the trade name to NITHIODOTE treat cyanide poisoning. The primary route of endogenous cyanide detoxification is by enzymatic transulfuration to thiocyanate (SCN- ), which is relatively nontoxic and readily excreted in the urine. Sodium thiosulfate is thought to serve as a sulfur donor in the reaction catalyzed by the enzyme rhodanese, thus enhancing the endogenous detoxification of cyanide. In addition, Sodium thiosulfate is used in calciphylaxis in hemodialysis patients with end-stage kidney disease. Calciphylaxis is vasculopathy characterized by ischemia and painful skin necrosis due to calcification and intimal fibroplasia of thrombosis of the panicular arterioles. Sodium thiosulfate is used as treatment due to its antioxidant activity and as a chelating. Sodium thiosulfate renders renal protection by modulating the mitochondrial KATP channel for preventing urolithiasis. Moreover, STS was assumed to play a vital role in on ischemia reperfusion injury (IR). The effectiveness of STS as a cardioprotective agent was attributed to the reduction of apoptosis by binding to the active site of caspase-3 in silico, which was substantiated by the reduced expression of caspase-3 and poly ADP ribose polymerase levels.
