Mical interactions amongst the drugs plus the microparticles. The diffractogram of BM showed two peaks at 13.72 and 232, whereas the diffractograms of MSO and MOG showed only one peak at 232 (Fig. 4c). The peak at 13.72 of BM was not visible in MSO and MOG. On the other hand, the peak at 232 was intensified. This may possibly be resulting from the interactions among the alginate plus the internal phase molecules, which resulted inside the alteration in the molecular packing in the alginate molecules. The alteration inside the molecular packing may well have already been linked using the formation of typical crystallites (18). The drug containing microparticles showed feeble peaks associated with all the drugs (Fig. 4d). This suggested that the physical nature of your drugs was not altered for the duration of encapsulation. Incorporation on the drugs inside the microparticles has altered the intensity in the peak at 232. This suggestedBM blank microparticles, MSO microparticles with sunflower oil, BMSA salicylic acid containing blank microparticles, BMMZ metronidazole containing blank microparticles, MSOSA microparticles with salicylic acid containing sunflower oil, MSOMZ microparticles with metronidazole containing sunflower oil, MOG microparticles with organogel, MOGSA microparticles with organogel containing salicylic acid, MOGMZ microparticles with organogel containing metronidazolemetronidazole, were observed in metronidazole containing microparticles (22). Even though the peaks on the drugs wereFig. 2.

Thermal Studies Figure 5a shows the thermograms of the organogel and created microparticles. The thermogram of sunflower oilshowed an endothermic peak at 34 . The organogel showed a broad endothermic peak at 95 . This can be due to the combined impact of melting of the organogel and evaporation of water present in the organogel (18). BM showed an endothermic peak at 100 which may possibly be attributed to the evaporation on the bound water linked using the alginate. While dried microparticles have been utilised, the thermal profile recommended that it was not feasible to take away the bound water totally. Related observations have also been reported earlier (23). MSO and MOG have shown endothermic peaks at 60 . This endothermic peak could be connected together with the heating of sunflower oil. In our previous study, we have discovered that the gel to sol transition temperature ofTable III.
