DISCUSSION 6.1 FTIR SPECTROSCOPY It was observed from the FTIR graph that there was no shifting of peaks of metronidazole i,e., characteristic peak of the amine group (N-H streching) present in imidazole nucleus at 1030 cm-1 and presence of NH2 group at 3298 cm-1 in formulation. Hence, there was no interaction between drug and polymer. 6.2 METRONIDAZOLE MICROSPHERES 6.2.1 Optimization of speed (rpm) for preparation of microspheres Metronidazole microspheres were prepared using emulsion…
