Two medicines, side by side

Pilocarpine vs timolol

Pilocarpine and timolol are both labeled for glaucoma. Drugs@FDA records approvals of pilocarpine since 1974 and of timolol since 1978. Pharmacies paid $0.338 per pilocarpine HCl 5 mg tablet and $0.774 per mL (Timolol maleate 0.5% eye drops) (NADAC, October 7, 2026); the strengths differ, so the two prices are not like for like. In FDA's classes, pilocarpine is a cholinergic receptor agonist and timolol a beta-adrenergic blocker.

Check it at the source: the pilocarpine FDA label on DailyMed (effective December 5, 2024); the timolol FDA label on DailyMed (effective June 27, 2025).
