De tre vigtigste metaboliseringsveje er følgende: monohydroxylering i dihydrobenzfuranringen; åbning af dihydrobenzfuranringen og; N- dealkylering af nitrogen i pyrrolidin.
The three main metabolic routes are as follows: monohydroxylation in the dihydrobenzofuran ring; dihydrobenzofuran ring opening and N-dealkylation of the pyrrolidine nitrogen.
