Abstract

Two crystalline polymorphic forms (7s,9as)-7-[3-cyanophenoxy]methyl-2-(5-fluoropyrimidin-2-yl)-2,3,4,6,78,9a-octahydro-1h pyrido [1,2-a]pyrazine-monochloride (the monohydrochloride)are form a and form b. The pharmaceutical composition containing at least one of these polymorphs has advantageous stability for formulation to treat anxiety, depression and psychotic diseases such as affective psychosis, schizophreia, and schizo-affective diorders. The administration of this pharmaceutical composition is oral by preferably by tablet or capsule. A method of making a and b forms is also disclosed.
