[Biotransformation of the anticholinesterase agent, 9-amino-7-methoxy-1,2,3,4-tetrahydroacridine].

Biotransformation of the anticholinesterasic agent 9-amino-7-methoxy-1,2,3,4-tetrahydroacridine was studied in the laboratory rat. In the animal urine, the main identified metabolites were 9-amino-7-hydroxy-1,2,3,4-tetrahydroacridine and its conjugate with glucuronic acid, or sulfuric acid, as well as 9-amino-1-hydroxy-7-methoxy-1,2,3,4-tetrahydroacridine and 9-amino-2-hydroxy-7-methoxy-1,2,3,4-tetrahydroacridine. A part of the drug was excreted in an unchanged form.
