BRIEF REVIEW ON NOVEL CONTROL DRUG DELIVERY SYSTEM OF OCULAR INSERT

There are several eye illnesses that can affect the eye and cause vision loss. As a result, there are numerous ophthalmic drug delivery systems accessible. There are two types of medication delivery systems; conventional and non-conventional. About 70% of the eye dose formulations on the market are eye drops and ointments, which are the most regularly accessible ophthalmic medications. Significant guidelines have been directed toward newer drug delivery systems for ophthalmic administration to improve ocular drug bioavailability. To avoid frequent drug administration, the researcher has always used an ocular insert to deliver the drug at a controlled rate. The ocular insert is made up of numerous layers of controlled, delayed, or sustained release biodegradable implantable components. According to their solubility, inserts can be classified as insoluble, soluble, or biodegradable. The drug's release from the insert is determined by diffusion, osmosis, and bio-erosion.
