    Product Description

    Levobetaxolol is an isomer of betaxolol (Item No. 18625) and antagonist of the β1-adrenergic receptor (β1-AR; Ki = 0.76 nM for the human receptor).1 It is selective for β1-ARs over β2-ARs (Ki = 32.6 nM), as well as a panel of 89 additional receptors (IC50s = >1 µM). Levobetaxolol inhibits cAMP production induced by isoproterenol (Item No. 15592) in human non-pigmented ciliary epithelial cells (Ki = 16.4 nM). Topical application of levobetaxolol (150 µg/eye) reduces intraocular pressure in a cynomolgus monkey model of ocular hypertension. Formulations containing levobetaxolol have been used in the treatment of glaucoma.

    WARNING This product is not for human or veterinary use.
