DEVELOPMENT AND EVALUATION OF CIPROFLOXACIN HYDROCHLORIDE LOADED OCULAR INSERT BY USING â€œPLANTAGO OVATAâ€ AS NATURAL POLYMER
Objective: The present work focus in the direction of â€œDevelopment and evaluation of Ciprofloxacin Hydrochloride loaded ocular insert by using â€œplantago ovataâ€ as natural polymerâ€. The current work was carried out to evaluate the control release profile of ocular insert. Natural polymer in ocular insert was used for studying the long acting property. Natural polymer is also used to enhance the bioavailability of drug and reduce toxicity. It is also used to increase the duration of action of drug for prolongs action and gives better in vitro performance as compare than to the conventional ocular formulation.
Methods: Solvent casting method was used in the formulation of Ciprofloxacin Hydrochloride loaded ocular inserts. Different ocular insert formulations of varying polymer concentration were prepared. Ocular insert formulation H-1 to H-3 was prepared by using different concentration of HPMC and formulation P-1 to P-4 was prepared by using different concentration of Plantago Ovata.
Results: The ocular inserts formulation was within the acceptable limits. All the pre formulation parameters of polymers such as derived properties, compressibility index, Hausnerâ€™s ratio, viscosity, melting point, swelling ratio, loss on drying, PH of mucilage solution and pre formulation of active pharmaceutical ingredient such as estimation of drug by using UV spectroscopy, determination of melting point, solubility, partition coefficient and FTIR for compatibility study of drug and excipient were evaluation. FTIR analysis also confirmed no drug-excipient interaction.Conclusion: Prepared inserts in the present study were semitransparent. The mixing of the drug in to the polymer is uniform, due to this; the drug content of all formulation is good. Formulation P4 was selected because it showed better release profile, drug content and other physicochemical properties than other formulated batch when compare. All the prepared inserts showed in vitro drug release for the period of 4 h as compare to the marketed formulation. An in vitro drug release study revealed that ocular formulation gives a prolong action. The formulation was found to be long acting.
