描述 | Ritodrine hydrochloride (DU21220 hydrochloride) is a β-2 adrenergic receptor agonist. In treating preterm labour, ritodrine can significantly prolong a short interval more quickly but with relatively more side effects than magnesium sulphate[3]. Multivariable analysis showed that the total dose of ritodrine was significantly associated with pulmonary oedema. Consideration of the total dose of ritodrine hydrochloride is helpful in the management of patients with threatened preterm labour in twin pregnancy[4]. However, long-term tocolysis with intravenous infusion of ritodrine hydrochloride, a betamimetic, can be selected as the first-line tocolytic treatment in Japan[5]. |

溶解方案 |
DMSO: 115 mg/mL(355.14 mM),配合低频超声助溶,注意:DMSO长时间开封后,会吸水并导致溶解能力下降,请避免使用长期开封的DMSO H2O: 100 mg/mL(308.82 mM) 以下溶解方案都请先按照体外实验的方式配制澄清的储备液,再依次添加助溶剂: ——为保证实验结果的可靠性,澄清的储备液可以根据储存条件,适当保存;体内实验的工作液,建议现用现配,当天使用; 以下溶剂前显示的百分比是指该溶剂在终溶液中的体积占比;如在配制过程中出现沉淀、析出现象,可以通过加热和/或超声的方式助溶
