Abstract

Objective: The study focus on the drug-drug and drug-polymer interaction and their estimation at stoichiometry when such systems were formed. In this discovery we tried to make use of the latest research and novel concepts to explore the drug-polymer-polymer Ionic ternary Interaction

Methods: Partial ternary phase diagrams were constructed and the stoichiometry of the ciprofloxacin/anionic polymer interaction was assessed in distilled water by means of dialysis equilibrium. The polymers were completely hydrated in distilled water by gentle stirring at room temperature and studied for viscosity and turbidimetric measurements.

Results: Comparing the partial ternary phase diagrams of the different anionic to each other. PAA exhibited the largest gel area even with low polymer content. The anionic polymers HA and PAA showed good capability to interact with the drug giving soluble drug/polymer complexes; moreover they were able to form polymer/polymer complexes with Poloxamer and HCS, with a stoichiometry depending on the polymers involved.

Conclusion: From the results of the present study, it can be concluded that formulations were made isotonic and favours corneal permeation of both the drug. Ocular Irritancy denotes formulations were quite stable & useful in novel format of sol-gel transformations.
