The goal of this research was to design thermosensitive drug vehicles for glaucoma therapy. Thermosensitive ophthalmic drop was prepared by mixing linear poly(N-isopropylacrylamide-g-2-hydroxyethyl methacrylate) (PNIPAAm-g-PHEMA), PNIPAAm-g-PHEMA gel particles and antiglaucoma drug. This produced polymeric eyedrop containing the drug epinephrine was a clear solution at room temperature which became...
In this study, controlled release ophthalmic agents for glaucoma therapy were developed based on the thermosensitivity of poly-N-isopropylacrylamide (PNIPAAm). The clear solution of PNIPAAm was known to undergo phase transition when the temperature was raised from the room temperature to about 32 o C. The drug was entrapped in the tangled polymer chains or encapsulated within the crosslinked...
