ABSTRACT
Cortexolone-17α-propionate (CP) is a topically active antiandrogen useful in the treatment of skin disorders. In the solid state, three anhydrous forms of this drug (CPI, CPII and CPIII) occur, together with one hydrated crystal (CPW). The single crystal structure of the monohydrated phase, CPW, compared with that of the anhydrous form CPIII, shows a markedly different solid state behavior. These latter pseudopolymorphic forms have also been fully characterized by spectroscopic methods.
