Development &; Characterization Of Ofloxacin &; Prednisolone Loaded NLCs : A Nano-structured Lipid Carriers (NLCs)

The present study was designed to develop and characterize nanostructured lipid carriers (NLC) of Ofloxacin and Prednisolone for topical use in case of infections associated with inflammation. Ofloxacin was obtained as gift sample from Mankind Pharma Ltd, Vill Kyarta, P.O. Misserwal, Poonta Sahib, Sir Mour. H.P. Whereas Prednisolone was purchased from Yarrow chem., Mumbai. It was evaluated for its pre-formulation studies (organoleptic properties, melting point, solubility, compatibility, max. wavelength of absorption). In pre-formulation study, drugs were found having the similar properties as described in Indian Pharmacopoeia (IP) and United States Pharmacopoeia (USP). SEM photomicrograph revealed that NLCs were spherical with more or less smooth surface; particle size 512.3-1703 nm and PDI- 0.399-0.742 (ofloxacin) and particle size 539.3-1736.7 nm and PDI- 0.335 - 0.711 (prednisolone) etc. In conclusion, the prepared NLCs had prolonged release effects with good potential for topical delivery of NLC based gel formulation of ofloxacin & prednisolone.
