Abstract
Aqueous gel drug delivery compositions and medical devices, useful for treating an eye condition, having hyperosmotic, iso-osmotic or hypo-osmotic characteristics in the gel state, are obtained by calculating the osmolality required in the liquid state to reach a desired osmotic force in the gelled state by assuming that a polyoxyalkylene block copolymer does not contribute to the osmolality in the gel state.
