The coprecipitate of anordrin-PVP wasprepared by solvent method. The differentialscanning calorimetry(DSC) revealed thatanordrin did not have crystalline structurein coprecipitetes(COPPT) of 1: 7- 1: 9、X--raydiffraction spectrum of 1:8 COPPT showedno crystalline structure of anordrin. Thedissolution rate fo anordrin in 20 min wasabout38t imes higher for 1:8 COPPT than that
