Olivan TS 0.3% Ophthalmic Suspension is an eye drop manufactured by Opsonin Pharma Limited in Bangladesh. It contains Nepafenac, a non-steroidal anti-inflammatory drug (NSAID) that, upon application, is converted into its active form, Amfenac, within the eye. Amfenac inhibits cyclooxygenase enzymes, thereby reducing the production of prostaglandins responsible for inflammation and pain.
