Celiprolol is a β1 adrenergic receptor antagonist and β2 adrenergic receptor partial agonist.

β2 adrenergic receptor agonists, also known as adrenergic β2 receptor agonists, are a class of drugs acting on the β2 adrenergic receptor. Like other β adrenergic agonists, they cause smooth muscle relaxation.

In vitro: The ability of celiprolol to induce the regulation of beta adrenergic receptors was investigated in S49 lymphoma cells. Results showed that celiprolol did not stimulate adenylate cyclase in membranes from wild-type (WT) S49 cells or induced the sequestration of beta adrenergic receptors on intact cells. Moreover, exposure of WT S49 cells to celiprolol led to the loss of around half of the total cellular beta adrenergic receptors [1].

In vivo: In a previous study, Japanese white rabbits underwent 30 min of ischemia and 48 h of reperfusion. Celiprolol was administered 20 min before ischemia with or without pretreatment with N(omega)-nitro-L-arginine methylester (L-NAME) or 5-hydroxydecanoic acid sodium salt (5-HD). Results showed that celiprolol could significantly reduce the infarct size dose-dependently. The infarct size-reducing effect of celiprolol was found to be completely blocked by L-NAME but not by 5-HD. In addition, celiprolol could increase the myocardial interstitial levels of NOx and reduce the intensity of myocardium staining [2].

Clinical trial: In a previous clinical study, the authors suggested that celiprolol might be the treatment to prevent major complications in patients with vascular Ehlers-Danlos syndrome [3].
