Homatropine Bromide is muscarinic AChR antagonist that is an anticholinergic medication.Target: mAChRHomatropine is an anticholinergic medication that is an antagonist at muscarinic acetylcholine receptors and thus the parasympathetic nervous system. Homatropine (20 μM) alone produces a dose ratio of 259 in atrium from guinea-pigs. Homatropine (20 μM) produces a dose ratio of only 95.0 when combined with hexamethonium in atrium from guinea-pigs [1]. Homatropine has similar affinities for muscarinic receptors in stomach (pA2 = 7.13) and for those in atria mediating force (pA2 = 7.21) and rate (pA2 = 7.07) responses [2]. Homatropine [14C]methylbromide administrated rectal achieves higher and rapid peak plasma concentrations than by the other routes in rats whether HMB-14C is administered in a water-soluble suppository base or in aqueous solution, retained 28% of the 14C has been excreted in the urine while 56% remained in the large intestine after 12 hours. Unlabelled Homatropine methylbromide, given in rectal suppositories to anaesthetized rats, causes prompt blockade of the effects of vagal stimulation on pulse rate and of intravenous acetylcholine on blood pressure [3].

计算结果:
工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
