[Application of thermal analysis to quality evaluation tests of drugs].

Thermal analysis method can be applied to the quality evaluation tests of drugs. Recent advances in the technology and the data-processing system on the apparatus have accelerated the utilization of this analytical techniques in the field of drug quality control. In this report, various application techniques of the thermal analysis such as DSC, DTA, TG and the impurity analysis by DSC, were reported and discussed from the viewpoints of a general test in the Japanese Pharmacopoeia. Further the present situations of this analytical method in the US Pharmacopoeia 23 and the British Pharmacopoeia 1993 are also explained.
