Levobetaxolol
Levobetaxolol is a potent and high affinity β-adrenergic antagonist with IC50 values of 33.2, 2970, 709 nM for guinea pig atrial β1, tracheal β2 and rat colonic β3 receptors, respectively. Levobetaxolol reduces IOP (intraocular pressure). Levobetaxolol exhibits a micromolar affinity for L-type Ca21-channels. Levobetaxolol decreases the effects of ischaemia/reperfusion injury in rats. Levobetaxolol has the potential for the research of glaucoma.
