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].

Target	IC50: 0.39 nM (Human mAChR M4) and 0.71 nM (Chicken mAChR M4)[3]
In Vitro	Atropine (Tropine tropate; 1 μM; pulmonary veins and arteries) hydrobromide inhibits ACh-induced relaxations in human pulmonary veins[4].
In Vivo	Atropine (Tropine tropate; 10 mg/kg; i.p.; once, for 40 minutes; Peromyscus sp.) hydrobromide inhibits the cardiac arrhythmia which normally occurs throughout torpor[2]. Animal Model: White-footed mice (Peromyscus sp.)[2] Dosage: 10 mg/kg Administration: Intraperitoneal injection; once, for 40 minutes Result: Increased heart rate was a decrease in cardiac arrhythmia.
