Abstract
The incorporation of polymeric excipients into an injectable hydrogel matrix, for example, methyl cellulose in the case of a hydrogel matrix comprising hyaluronan and methylcellulose (HAMC) has been found to increase the solubility of sparingly soluble hydrophobic drugs and tune their rate of release. The hydrogel matrix may also include other sparingly soluble hydrophobic food or cosmetic agents.
