Ali, K. A. published the artcileThe thermal analysis of felodipine and ramipril: application to quality control, Quality Control of 72509-76-3, the main research area is Triacor felodipine ramipril quality control thermogravimetry.
Thermal behavior of Felodipine (FEL) and Ramipril (RAM) drugs was studied in drug substance, binary mixture and co-formulated tablets. Some thermal anal. methods such as thermogravimetric anal. (TGA), derivative thermogravimetry (DrTGA), DTA (DTA) and differential scanning calorimetry (DSC) were used to investigate the thermal behavior of both drugs. The thermogravimetric data allowed the determination of different thermodn. and kinetic parameters such as: Ea, ΔH, ΔS and ΔG. The drugs purity was found to be 99.88% and 99.92% for FEL and RAM, resp. The simplicity, speed and low cost of the thermal anal. justify its application in the quality control of pharmaceutical drugs.
