Abstract

Polymorf form (l) finasterid blir fremstilt ved først å danne et vesentlig uoppløselig kompleks av finasterid og et gruppe (l) eller gruppe (II) -metallsalt, så som litiumbromid, og deretter dissosiering av komplekset ved å løse bort saltkomponenten med vann, for å oppnå vesentlig ren form (l) polymorf, krystallinsk finasterid.
