The gel comprises an ophthalmic drug carried in a gel which provides good ocular retention while avoiding burst release of medicament and yet at the same time providing controlled release of the medicament. The gel contains in combination sodium carboxymethyl-cellulose and colloidal magnesium aluminum silicate. A combination of these ingredients in the gel provides the desired effects.
