An Investigation into Some Pharmaceutical Interactions by Differential Scanning Calorimetry

Abstract
Differential scanning calorimetry has been used to investigate the interactions between the drugs indomethacin and chlorproparaide with some tablet excipients, and also between the excipients themselves. Chlorpropamide was found to interact with both sodium starch glycolate and magnesium stearate, indomethacin with magnesium stearate and the tablet binder polyethylene glycol 6000 with microfine cellulose.
