<unk> , sold under the brand name Combigan, is a fixed-dose combination medication eye drop indicated for the treatment of glaucoma. It is a combination of<unk>  (an α2 adrenergic agonist) and timolol (a β adrenergic blocker), in concentrations of 0.2% and 0.5% respectively. Both substances work by decreasing the synthesis of aqueous humor. Combigan is marketed and sold by Allergan. It has been approved by regulatory authorities in Europe, Canada, and the United States for reduction of intraocular pressure (IOP) in patients with glaucoma or ocular hypertension. Although clinical studies showed that the IOP-lowering effect was slightly greater (1-2 mmHg) with concomitant administration of 0.5% timolol twice daily and 0.2%<unk>  tartrate three times daily than with Combigan twice daily, the safety profile of latter was more favorable.
