Amfenac (AHR 5850) is a non-steroidal anti-inflammatory compound possessing antipyretic and analgesic properties. It is an inhibitor of cyclooxygenases. Amfenac sodium has been on the Japanese market since 1986 (as FENAZOX®, Meiji) in an oral dosage form (50 mg, four-times-daily) indicated for the treatment of pain and inflammation associated with rheumatoid and osteoarthritis and low back pain, as well as the treatment of pain and inflammation following surgery, injury or tooth extraction. Amfenac is an active moiety of nepafenac (amfenac amide), the prodrug has very weak cyclooxygenase inhibitory activity whereas amfenac exhibits more potent cyclooxygenase activity. Nepafenac at a concentration of 0.1% (NEVANAC) was approved for marketing in the US in 2005. Nepafenac is also approved for marketing in the European Union(EU) and Japan as well as over 60 other countries for the treatment of postoperative pain and inflammation associated with cataract surgery.

Trypan blue (trade name MembraneBlue, VisionBlue) is a vital stain used to selectively color dead tissues or cells blue. Live cells or tissues with intact cell membranes are not colored. Since cells are very selective in the compounds that pass through the membrane, in a viable cell trypan blue is not absorbed; however, it traverses the membrane in a dead cell. Hence, dead cells are shown as a distinctive blue color under a microscope. Since live cells are excluded from staining, this staining method is also described as a dye exclusion method. This dye may be a cause of certain birth defects such as encephalocele. Trypan blue is commonly used in microscopy (for cell counting) and in laboratory mice for assessment of tissue viability. The method cannot distinguish between necrotic and apoptotic cells. Trypan blue is also used in ophthalmic cataract surgery to stain the anterior capsule in the presence of a mature cataract, to aid in visualization, before creating the continuous curvilinear capsulorhexis.

Bendazac, (1-benzyl-1H-indazol-3-yl-oxy)-acetic acid, is structurally related to indomethacin. Its lysine salt has been reported to be absorbed better than the parent compound. It is applied topically as bendazac lysine 0.5% (wt/vol) aqueous solution for delaying the progression of cataract. Topical application of bendazac is associated with transient burning sensation. It reduces the secretion of the skin ulcer surface, promotes skin formation and accelerates tissue repair.
