Application of Carbomer in Ophthalmic Gel Preparation

Application of Carbomer in Ophthalmic Gel Preparation
Due to the special eye protection mechanism, such as tear flushing, blinking movement, corneal low permeability and many other physiological factors, ordinary eye drops will be quickly eliminated, drug absorption is limited, and the bioavailability after eye administration is restricted. Improving the bioavailability of drugs in ophthalmic preparations mainly depends on the retention time of drugs in the eye (cornea). The longer the time, the greater the amount of drugs absorbed and the better the curative effect. Some dosage forms such as suspension or eye ointment can stay in the eyes, but solid or semi-solid will make the patient uncomfortable. Carbomer gel has good adhesion, non-toxic and non irritant. It can extend the time of action and increase the absorption and utilization of drugs. The study showed that the contact time between Carbomer gel and eye was concentration dependent.
