Application of the Thermal Analysis Method to Pharmaceutics

The termal Analysis method has many virtues of operating morosely:the quantity of the needed sample was very small and the reproductivity of this method was satisfactory,therefore it is used in the chemical industry,the mineral products,the metallurigical industry,the food products and medicincs,et al.The paper concisely introduces the application of the thermal analysis method to pharmaceutics in recent years.a.The study on the change from the amorphous form to the crystal morphology of a medicine in the pharmaceutical process.b.The effect of storage conditions on the change of crystal morphology.c.The distinction of the inclusion compound of a medicine with cyD and its derivation in the ointment containing propylene glycol.d.The study on solid dispersion of medicine in the controlledreleased tablet.e.The study on stabilization of tablets in the presence of excipients and in the presence of moisture.f.The distinction of the skin state for investigation of perculaneous absorption dosage.
