Pharmacokinetic properties

Coated tabletsCapsulesPillsIt is rapidly absorbed when taken orally. When taken orally at doses of 400-500 mg, the Cmax is 3.5-4 mcg/ml. It is rapidly distributed in organs and tissues. The average retention time of the drug in the body when taken orally is 4.9–5.2 hours. It is metabolized in the liver by glucuronconjugation. 5 metabolites were identified: 3-oxypyridine phosphate-is formed in the liver and, with the participation of alkaline phosphatase, breaks down into phosphoric acid and 3-oxypyridine

With intravenous administration, the drug quickly (within 0.5–1.5 hours) passes from the bloodstream to organs and tissues, and therefore its concentration in unchanged form quickly decreases. When administered in therapeutic doses, the Cmax of the drug in the blood plasma is reached in 30-40 minutes and is 2.5-3 mcg/ml, while its metabolites are determined in the blood plasma for 7-9 hours.

The drug is excreted from the body in the urine in glucuronoconjugated form, as well as in small amounts in unchanged form.

Suction and distribution. It is rapidly absorbed when taken orally (the half-absorption period is about 1 h). Tmax when taken orally is 0.5 h. Cmax when taken orally is 50-100 ng / ml. It is rapidly distributed in organs and tissues. The average retention time of ethylmethylhydroxypyridine succinate in the body when taken orally is about 5 hours.

Metabolism. Метаболизируется в печени путем глюкуронирования. Идентифицировано 5 метаболитов: 3-оксипиридина фосфат — образуется в печени и при участии ЩФ распадается на фосфорную кислоту и 3-оксипиридин; 2-й метаболит — фармакологически активный, образуется в больших количествах и обнаруживается в моче на 1–2-е сут после введения; 3-й — выводится в больших количествах с мочой; 4-й и 5-й — глюкуронконъюгаты.

Output. T1/2 when taken orally-4-5 hours. It is rapidly excreted in the urine mainly in the form of metabolites (50% in 12 hours) and in a small amount (0.3% in 12 hours) - in an unchanged form. It is most intensively excreted during the first 4 hours after taking the drug. Indicators of urinary excretion of unchanged drug and metabolites have individual variability.
