Objective: The envisaged research work aims to develop a nanosponge loaded gel for the treatment of Streptococcal gangrene.
Methods: In the present study, permeability is enhanced by targeted drug release formulation of topical clindamycin phosphate nanosponges were prepared by emulsion solvent diffusion method using ethyl cellulose as release retardant polymer and PVA as surfactant or emulsifier. Nanosponges were prepared by emulsion solvent diffusion method by changing drug polymer ratio (1:0.05, 1:0.1, and 1:0.15) and process parameters were optimized using 32 full factorial central design. CP nanosponges were then incorporated into a hydrogel prepared using Carbopol 934.
Results and Discussion: The drug loaded nanosponges were evaluated for physical appearance, drug content, entrapment efficiency, and particle size. Characterization of CP nanosponges was done by SEM for the formulation. In vitro release study indicated that the release of CP varied according to the concentration of matrix forming polymer. The best standardized formulation G5 and G6 were further evaluated for microbiological studies. Microbial studies were done using Staphylococcus aureus as the strain organism and the activity of the gel against the organism was evaluated by measuring the zone of inhibition. It was also found to be stable for 2 months during its stability studies.
Conclusion: Thus, it was concluded that CP can be formulated as nanosponge hydrogel that can release the drug up to 24 h with increased permeability and targeted release. Therefore, clindamycin phosphate nanosponges prepared are promising drug delivery for topical application as being more useful than conventional formulation therapy.
