Iso-osmotic, hyperosmotic, or hypo-osmotic, pH balanced, thermoreversible gels are ideal medical devices or vehicles for drug delivery to the skin of a mammal. The osmolality in the gel state can be calculated by assuming that a polyoxyalkylene block copolymer or polyether present in said gel does not contribute to the osmolality in the gel state, although it does contribute to the measured osmolality in the liquid state. |
