Attachment of lectin to the Ethylcellulose microspheres significantly increased the mucoadhesiveness and also controls the release of Clarithromycin in simulated GI fluids. Conjugation aggregation assay suggesting that the lectin can be able to target in the treatment of Helicobacter pylori infection in peptic ulcer disease. Gamma scintigraphy study suggesting that Con-A lectin conjugated Ethylcellulose microspheres have gained considerable attention due to their ability to adhere to the mucus layer, as well as to release the drug in a controlled manner.
