Torsemide is a pyridine-sulfonyl urea type loop diuretic.Target: OthersTorasemide is a pyridine-sulfonylurea type loop diuretic mainly used in the management of edema associated with congestive heart failure. It is also used at low doses for the management of hypertension. Torsemide significantly reduced total HF readmissions (relative risk [RR]: 0.41, 95% CI: 0.28-0.61, p < 0.0001) and HF readmissions (RR: 0.53, 95% CI: 0.33-0.84, p = 0.008) as well as CV readmissions (RR: 0.77, 95% CI: 0.60-0.98, p = 0.03) in patients with "at least 1 readmission." Torsemide caused a 14% reduction in all-cause mortality (RR: 0.86 [0.53-1.39], p = 0.54). Torsemide significantly reduces HF and CV-related hospital readmissions in systolic HF. Furthermore, torsemide is associated with a trend in reducing all-cause mortality [1]. Torsemide has several characteristics that make it suitable for treatment of advanced heart failure including longer half-life, increased potency of diuretic action, and anti-aldosterone effects. This case report details the administration of torsemide in 3 dogs with advanced heart failure and apparent furosemide resistance [2].

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。
