Atropine (hydrobromide)

Atropine (Tropine tropate) hydrobromide is a competitive muscarinic acetylcholine receptor (mAChR) antagonist with IC50 values of 0.39 and 0.71 nM for Human mAChR M4 and Chicken mAChR M4, respectively. Atropine hydrobromide inhibits ACh-induced relaxations in human pulmonary veins. Atropine hydrobromide can be used for research of anti-myopia and bradycardia[1][2][3][4].
