Pharmacokinetic analyses using absorption kinetics in low-alcohol dose cases of drunken driving

Mathematical modeling of the kinetics of multiple ethanol intake

The aim of the study is to construct a mathematical model of the kinetics of multiple ethanol intake based on the kinetic equation of zero-order ethanol elimination with absorption and irrevocable first-order absorption deficiency, as well as its implementation in the format of a computer program. Analytical mathematical modeling of the kinetics of multiple oral administration of ethanol is performed on the basis of this kinetic equation. In the course of modeling, a kinetic summation method was developed that allows to perform a mathematical description of the dynamics of ethanol content in the body in the case of repeated intake of alcoholic beverages of any volume and strength, separated by time intervals of any duration. The developed computational algorithm is implemented in the format of the Alcohol Calculator V 3.0 computer program. The conclusion is made about the expediency of using the developed information and computing technology in the forensic assessment of the quantitative alcohol content in the body at a legally relevant time. 

Mathematical modeling of the kinetics of a single intake of ethanol

The aim of the study is to construct a kinetic equation of zero-order ethanol elimination with first-order absorption, taking into account the presystemic metabolism of ethanol, with the possibility of determining the errors in estimating the parameters of the model, as well as the implementation of the model in the format of a computer program. Analytical mathematical modeling of the kinetics of a single oral intake of ethanol has been performed. A mathematical model of the kinetics of a single intake of ethanol with its zero-order elimination, absorption and first-order presystemic metabolism has been developed. A method is proposed for estimating the limiting absolute errors of the kinetic parameters of the constructed model based on the summation of the partial contributions of the initial physical quantities. The complex of the developed computational procedures is implemented in the format of the «Alcohol Calculator V 1.0» computer program. The conclusion is made about the expediency of using the developed information and computing technology in the forensic medical expert assessment of acute alcohol intoxication.
