The exact mechanism by which levobetaxolol lowers intraocular pressure is not known. It it thought that antagonism of β-adrenergic receptors may reduce the production of aqueous humour stimulated via the cyclic adenosine monophosphate-protein kinase A pathway . It is also thought that the vasoconstriction produced by antagonism of β adrenergic receptors reduces blood flow to the eye and therefore the ultrafiltration responsible for aqueous humour production. β1 selective antagonists are less effective than non-selective β adrenergic receptor antagonists because β2 receptors make up the bulk of the population in the eye. They do, however, come with the benefit of reduced respiratory complications.
Used in the treatment of open-angle glaucoma and ocular hypertension .
