GENERIC NAME: timolol ophthalmic solution

BRAND NAME: Timoptic, Timoptic-XE, Timoptic in Ocudose

DRUG CLASS AND MECHANISM: Timolol is a beta-adrenergic blocking agent. Like other beta-adrenergic blocking agents, it mainly blocks the action of the sympathetic (adrenergic) nervous system, for example, on the heart. In addition to its effect on the heart, timolol causes a reduction of the pressure within the eye (intraocular pressure). This effect is may result from a reduction in production of the liquid (aqueous humor) within the eye. The precise mechanism of this effect is not known. The reduction in intraocular pressure reduces the risk of damage to the optic nerve and loss of vision in patients with glaucoma. Timolol was approved by the FDA for ocular use in 1978.

PRESCRIBED FOR: Timolol is used for the treatment of glaucoma. Oral timolol tablets are used for treating high blood pressure and angina, but this doage form is not discussed in this article.

SIDE EFFECTS: Common side effects include:

Ophthalmic timolol can cause irritation to the eye which may manifest as pain or dryness in some people.
