INNO-8875 is an adenosine A1 receptor agonist.1,2 It binds to adenosine A1 receptors (Ki = 0.97 nM) and is greater than 10,000-fold selective for adenosine A1 over A2 receptors. Topical application of INNO-8875 (25 µg/eye) reduces intraocular pressure in a rabbit model of ocular hypertension.2 INNO-8875 (1-50 µg/kg) decreases atrial refractoriness and heart rate, as well as slows atrioventricular nodal conduction, in anesthetized rats.1
