Limited residence time of drugs in the ocular surface, poor bioavailability and side effects are the major challenges in ophthalmic treatment. From the last decade, the pharmaceutical industry is in search of a reliable ophthalmic drug delivery system. In the present study, we demonstrate amine‐functionalized mucoadhesive MIL88B(FeMOF) as a drug delivery cargo to encapsulate ophthalmic drug Timolol (TM) at a rate of 195 μg/mg. Invitro release of TM (only upto 63 %) from loaded FeMOF (TM@FeMOF) within 10 h without burst effect was a noticeable feature that anticipates enhanced preocular retention by the sustained release of TM through extensive H‐bonding of the amine group of MOFs with mucin. A novel and facile approach using Differential Pulse Voltammetry (DPV) were harnessed for rapid quantification of TM during in‐vitro release studies, further validated by HPLC measurement(<10 % deviation). The encouraging results from in‐vitro studies forecast the success story of TM@FeMOF as a biocompatible, biodegradable, and sustainable ophthalmic drug delivery system.
