Suction
Mebeverin is quickly and completely absorbed after ingestion. The modified release dosage form allows to use the dosing regimen 2 times a day.
Distribution
When taking repeated doses of the drug, significant accumulation does not occur.
Metabolism
Mebeverina hydrochloride is mainly metabolized by esterases, which in the first stage split the ether into veratric acid and mebeverine alcohol. The main metabolite circulating in the blood plasma is demethylated carboxylic acid. The half-life in the equilibrium state of the demethylated carboxylic acid is approximately 5.77 hours. When taking repeated doses (200 mg twice a day), the maximum concentration of demethylated carboxylic acid in the blood plasma (Cmax) is 804 ng / ml, the time to reach the maximum concentration of demethylated carboxylic acid in the blood (TmOh) - about 3 hours.
The average value of the relative bioavailability of the drug in the modified release capsule is about 97%.
Excretion
Mebeverin as such is not excreted from the body, but is completely metabolized; its metabolites are almost completely eliminated from the body. Veratric acid is excreted by the kidneys. Mebeverine alcohol is also excreted by the kidneys, partly in the form of a carboxylic acid and partly as a demethylated carboxylic acid.
