In the present study, we investigated the polymorphism of doxazosin mesylate. The polymorphs of doxazosin mesylate were characterized by determining powder Xray diffraction, DSC and TG patterns. MATERIALS AND METHODS Materials Doxazosin mesylate was donated by ChemGen Co., Ltd. (Korea). Other chemicals and solvents were of analytical reagent or special grade. Preparation of polymorphic. Doxazosin mesylate (DM) is a class II drug in the Biopharmaceutics Classification System (BCS) that is used in several types of hypertension treatments. DM presents almost 20 different polymorphs described in literature/patents, whose existence are usually supported by powder X-ray diffraction (PXRD) data. However, only the crystal form termed. Abstract. Seven polymorphic modifications of doxazosin mesylate, designed as forms A, D, E, F, G, H, I, and the amorphous state were studied by thermal methods (TG. Nine polymorphic modifications of doxazosin mesylate have been obtained by recrystallization in organic solvents under variable conditions. Different polymorphs of doxazosin mesylate were. Different polymorphs of doxazosin mesylate were characterized by powder X-ray crystallography diffractometry (PXRD), differential scanning calorimetry (DSC), and thermogravimetric analysis (TG.
