| Outline of Final Research Achievements |
Our analytical findings on drugs in forensic autopsy cases demonstrated that: (1) basic drugs such as methamphetamine and ephedrine that are excreted into urine as unmetabolized form into urine at a large proportion appear at a higher concentration in urine than in the stomach when administered intravenously, and basic drugs that are mostly excreted into urine as metabolized form appear at a higher concentration in the stomach than in urine after intravenous administration; and (2) metabolites of a basic drug which increase gradually in blood are rapidly excreted into the stomach if they preserve basic character.
An animal experiment using rabbits demonstrated that flecainide, a basic drug, is rapidly excreted into the stomach when it is intravenously administered. We established an animal model using rats for investigating excretion patterns of methamphetamine into the stomach.
