ABSTRACT
In this study, it was studied the thermal decomposition of pefloxacin mesylate and some mixture
with excipients containing the same active compound using DSC technique. The kinetic
parameters were obtained from DSC curves using nitrogen under dynamic atmosphere and
maintaining at constant temperature range. The data showed that the pefloxacin mesylate –active
substance is thermally more stable than the mixtures with any excipient. The decrease in stability
was attributed to the presence of excipients in formulation and to their possible interactions with
the pefloxacin mesylate the difference in stability is bigger between the pure substance and the
mixture with the magnesium stearate.
