Aspartame-Direct Compression Excipients: Preformulation Stability Screening Using Differential Scanning Calorimetry

Abstract

Differential scanning calorimetry was used as a screening technique for assessing the compatibility of Aspartame with some of the currently available direct compression excipients. AsDartame was found to be compatible with Avicel PH 101, Avicel PH 105, Elcema F 150, Elcema G 250, Sta-Rx 1500, Cab-O-Sil, Sorbitol, Di-Pac and Brownex Sugar, while incompatible with dicalcium phosphate dihydrate. It appears that stearic acid can be used as a lubricant in formulations containing Aspartame while magnesium stearate cannot.
