Thermal analysis study of antihypertensive drugs telmisartan and cilazapril.

Purpose: The aim of the present work is to study the thermal analysis of telmisartan and cilazapril.

Methods: Thermogravimetry (TGA), derivative thermogravimetry (DTG) and differential thermal analysis (DTA) were used through the work to achieve the thermal analysis study of some antihypertensive drugs, telmisartan and cilazapril.

Results: The results led to thermal stability data and also to the interpretation concerning the thermal decomposition.
