Which cap color is shared by Dorzolamide (Trusopt) and Brinzolamide (Azopt)?

• A. White
• B. Yellow
• C. Purple
• D. Orange

Answer: (D)

Cap color in ophthalmic bottles is a practical visual cue used by manufacturers to help quickly identify drug classes. Dorzolamide and Brinzolamide are both topical carbonic anhydrase inhibitors that lower intraocular pressure by reducing aqueous humor production. In many brand lines, these two medications share an orange cap, so they have the same cap color. This color helps clinicians and patients recognize they belong to the same drug class, even if the exact brand name differs. The color is a packaging convention, not a difference in how the drug works.
