Mechanism of action

Timolol blocks beta-1 and beta-2 adrenergic receptors on the ciliary body epithelium, which reduces the rate of aqueous humor secretion. This leads to a decrease in intraocular pressure, making it effective for treating glaucoma and ocular hypertension. The 0.5% topical formulation is applied directly to the eye for local therapeutic effect.
