Abstract

Kolon telah dilaporkan sebagai tapak sasaran yang sesuai bagi penyerapan sistemik protein dan peptida terapeutik drug kerana aktiviti peptidase yang lebih rendah, meghampiri pH neutral dan keadaan ‘perbalahan’ yang kurang jika dibandingkan dengan kawasan lain daripada saluran pencernaan. Bentuk dosaj yang diformulasikan mesti melalui saluran pencernaan bahagian atas dalam bentuk utuh sebelum penghantaran drug kepada kolon. Penggunaan polimer disulfida sebagai satu penghantaran responsif bakteria merupakan salah satu strategi untuk menyasarkan drug kepada kolon bagi melepaskan drug secara khusus dalam kolon. Colon has been reported as a favourable target site for the systemic absorption of therapeutic protein and peptide drugs, because of its lower peptidase activity, near neutral pH and less hostile conditions as compared with other regions of gastrointestinal tract. The formulated dosage form must pass through the upper gastrointestinal tract in intact form before delivering the drug to the colon. The use of disulphide polymers, a bacteria responsive delivery, is one of the strategies for targeting drugs to the colon and to release drug specifically in the colon.
