Description: Otenzepad, also known as AF-DX 116, is a selective M2 antagonist. Oral AF-DX 116 resulted in greater elevation of DBP than SBP in unstressed rats. In stressed rats, greater and more prolonged elevation of SBP than in unstressed rats was noted, particularly at higher doses. he effects of AF-DX 116 on blood pressure and heart rate thus may arise from peripheral action and AF-DX 116 may be useful for treating hypotension related to autonomic imbalance of the vagotonia type.

Product Data:
Biological target: Otenzepad (AF-DX 116) is a selective and competitive M2 muscarinic acetylcholine receptor antagonist.
In vitro activity: This study investigated the effect of the mAChR agonist carbachol (CCh) and various mAChR antagonists in human cortical slices (from tissue removed during neurosurgical treatment of epilepsy) by intracellular and extracellular recordings. AF-DX 116 prevented the CCh-induced depression of evoked EPSP when applied before CCh. CCh also depressed GABAergic transmission and this effect was antagonised by AF-DX 116. Reference: Neuroscience. 2012 Oct 25;223:399-411. https://pubmed.ncbi.nlm.nih.gov/22863677/
In vivo activity: The present study examined the effect of systemic post-training administration of the acetylcholine muscarinic M2 receptor antagonist AF-DX 116 on the acquisition of two 8-arm radial maze tasks. AF-DX 116 (0.5 and 1.0 mg/kg) significantly improved win-stay acquisition relative to vehicle-injected controls. AF-DX 116 (2.0 mg/kg) significantly improved retention relative to vehicle controls. The results demonstrate that post-training injection of the selective M2 receptor antagonist AF-DX 116 improves memory in a time-dependent manner.
