A mint green cap is most commonly associated with which product type?

• A. Fixed combination without beta-blocker
• B. Cholinergic agonist
• C. Prostaglandin analog
• D. Beta-blocker with prostaglandin

Answer: (A)

Cap color coding for glaucoma eye drops is a quick way clinicians identify the product type. A mint green cap signals a fixed combination without a beta-blocker, meaning two active ingredients are combined in one drop but neither is timolol or another beta-blocker. This distinction helps separate it from other product types: a cholinergic agonist is typically a single agent with its own cap color, a prostaglandin analog is usually a single agent with a different cap color, and a fixed combination that includes a beta-blocker would align with the cap color used for beta-blocker–containing products. So the mint green cap best matches a fixed combination without beta-blocker.
