Timolol maleate is a non-selective beta-adrenergic receptor blocker. In its oral form (Blocadren), it is used to treat high blood pressure and prevent heart attacks, and occasionally to prevent migraine headaches. In its ophthalmic form (brand names Timoptol in Italy; Timoptic), it is used to treat open-angle and occasionally secondary glaucoma by reducing aqueous humour production through blockade of the beta receptors on the ciliary epithelium.
