ABSTRACT
Acyclovir is an Anti-viral drug, widely used in the treatment of Ocular herpes simplex. Ophthalmic insert of acyclovir formulated using Methyl cellulose (MC A4CP), polyvinylpyrrolidone (PVP K30) and polyvinyl alcohol as polymers and glycerin use as plasticizer by solvent casting method with aim of increasing the contact time, achieving sustained release drug. The prepared ophthalmic insert were evaluated for uniformity of thickness, weight uniformity, drug content, % moisture absorption, % moisture loss, folding endurance and surface pH. In vitro drug release of formulated batches was performed using Modified Franz Diffusion cell. A 32 full factorial design was applied to systematically optimize the ocular insert. FTIR spectroscopy was performed to study the drug interaction effect in formulation using KBr disc method. On the basis of all physicochemical parameters and in vitro drug release studies, and overall Desirability, the formulation (F8) was found to vary significantly depending on the type of polymers used and their combinations and it was selected for sterility, stability, ocular irritancy study. The result of invitro diffusion study of formulation exhibited non-fickian in nature. From stability studies inserts were remained stable both physically and chemically. The formulation was found to be practically nonirritant in ocular irritation studies using hen's egg chorioallantoic membrane.
