The aim of the present work is to formulate suitable ocular films of timolol maleate for the treatment of primary open angle glaucoma which remains in the cul-de-sac, and achieve the sustained release of the drug during the desired period of the treatment. Method includes optimization of the formulation using various polymers and plasticizers. The drug timolol maleate is used among other things in eye-drops for the treatment of glaucoma but topically applied ophthalmic solutions often exhibit low bioavailability due to rapid tear fluid turn-over and drainage. In this article various physicochemical properties of timolol maleate is given ad formulation of film with its absorption maxima, standard curve and solubility profile is mentioned.
