Description
Sources: http://www.allergan.com/assets/pdf/betagan_pi
Curator's Comment: description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/11572462 | https://www.drugs.com/pro/levobunolol.html | https://www.ncbi.nlm.nih.gov/pubmed/3019819 | https://www.ncbi.nlm.nih.gov/pubmed/17459374

Levobunolol is a non-cardioselective beta-adrenoceptor blocking agent, equipotent at both beta1 and beta2 adrenergic receptors. Levobunolol is greater than 60 times more potent than its dextro isomer in its beta-blocking activity, yet equipotent in its potential for direct myocardial depression. Accordingly, the levo isomer, levobunolol, is used. Levobunolol does not have significant local anesthetic (membrane-stabilizing) or intrinsic sympathomimetic activity. Levobunolol, sold under the brand name Betagan, has been shown to be an active agent in lowering elevated as well as normal intraocular pressure (IOP) whether or not accompanied by glaucoma. Levobunolol is contraindicated in those individuals with bronchial asthma or with a history of bronchial asthma, or severe chronic obstructive pulmonary disease sinus bradycardia; second and third-degree atrioventricular block; overt cardiac failure cardiogenic shock; or hypersensitivity to any component of these products.

Sample Use Guides

In Vivo Use Guide

The recommended starting dose is one to two drops of BETAGAN (Levobunolol) ophthalmic solution 0.5% in the affected eye(s) once a day. Typical dosing with BETAGAN® 0.25% is one to two drops twice daily. In patients with more severe or uncontrolled glaucoma, BETAGAN® 0.5% can be administered b.i.d. As with any new medication, careful monitoring of patients is advised. Dosages above one drop of BETAGAN® 0.5% b.i.d. are not generally more effective.

Route of Administration: Topical

In Vitro Use Guide

The ability of levobunolol to relax ciliary artery rings pre-contracted with other agents, including phenylephrine and in Ca2+-free media was determined by isometric tension recording method. The pre-contraction was maintained for 20 min, then levobunolol was applied every 10 min in a cumulative manner. Levobunolol at 30 mkM and at 100 mkM significantly reduced the contractile response to phenylephrine.
