Design and Characterization of pH Responsive Ophthalmic In-situ Gel containing Cromolyn Sodium for Enhanced Drug Delivery
Cromolyn sodium, a mast cell stabilizer, is widely used in VKC management but suffers from poor patient compliance due to frequent dosing. In-situ gel systems offer a promising alternative for sustained ocular drug delivery, with polymers like chitosan and HPMC enabling pH-sensitive sol-to-gel transitions upon contact...
