Effects During Pregnancy and Lactation
◉ Summary of Use during Lactation Ulipristal is a selective progesterone receptor modulator used in a single dose as an emergency postcoital contraceptive. No information is available on the clinical use of ulipristal during breastfeeding; however, amounts in milk are low. If ulipristal is required by the mother, it is not a reason to discontinue breastfeeding. Some older sources recommend withholding breastfeeding for 24 hours after a dose, but this is no longer a requirement according to current FDA-approved labeling. ◉ Effects in Breastfed Infants Relevant published information was not found as of the revision date. ◉ Effects on Lactation and Breastmilk Relevant published information was not found as of the revision date. Protein Binding >94% bound to plasma proteins such as albumin, alpha1-acid glycoprotein, lipoproteins (VLDL, LDL, and HDL- due to its lipophillic nature) |

Pharmacodynamics
Ulipristal is a selective, reversible progestin receptor modulator and its tissue targets include the uterus, cervix, ovaries, and hypothalamus. Ulipristal may act as an agonist or antagonist in the presence or absence of progesterone based on the tissue target. If given mid-follicular phase, development of the follicle growth is delayed and estradiol concentrations decrease. If given at the time when luteinizing hormone peaks, follicular rapture is delayed by several days. If given early-luteal phase, a decrease in endometrial thickness can be observed. |

| 溶解度 (体内实验) |
配方 1 中的溶解度: ≥ 6.25 mg/mL (14.41 mM) (饱和度未知) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (这些助溶剂从左到右依次添加，逐一添加), 澄清溶液。
例如，若需制备1 mL的工作液，将 100 μL 62.5 mg/mL 澄清 DMSO 储备液加入 900 μL 20% SBE-β-CD 生理盐水溶液中，混匀。 *20% SBE-β-CD 生理盐水溶液的制备（4°C，1 周）：将 2 g SBE-β-CD 溶解于 10 mL 生理盐水中，得到澄清溶液。 配方 2 中的溶解度: ≥ 6.25 mg/mL (14.41 mM) (饱和度未知) in 10% DMSO + 90% Corn Oil (这些助溶剂从左到右依次添加，逐一添加), 澄清溶液。 例如，若需制备1 mL的工作液，可将 100 μL 62.5 mg/mL 澄清 DMSO 储备液添加到 900 μL 玉米油中并混合均匀。 请根据您的实验动物和给药方式选择适当的溶解配方/方案： 1、请先配制澄清的储备液(如：用DMSO配置50 或 100 mg/mL母液(储备液)); 2、取适量母液，按从左到右的顺序依次添加助溶剂，澄清后再加入下一助溶剂。以 下列配方为例说明 (注意此配方只用于说明，并不一定代表此产品 的实际溶解配方): 10% DMSO → 40% PEG300 → 5% Tween-80 → 45% ddH2O (或 saline); 假设最终工作液的体积为 1 mL, 浓度为5 mg/mL: 取 100 μL 50 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中，混合均匀/澄清；向上述体系中加入50 μL Tween-80，混合均匀/澄清；然后继续加入450 μL ddH2O (或 saline)定容至 1 mL； 3、溶剂前显示的百分比是指该溶剂在最终溶液/工作液中的体积所占比例; 4、 如产品在配制过程中出现沉淀/析出，可通过加热(≤50℃)或超声的方式助溶; 5、为保证最佳实验结果，工作液请现配现用！ 6、如不确定怎么将母液配置成体内动物实验的工作液，请查看说明书或联系我们; 7、 以上所有助溶剂都可在 Invivochem.cn网站购买。 |
| 制备储备液 | 1 mg | 5 mg | 10 mg | |
| 1 mM | 2.3064 mL | 11.5319 mL | 23.0638 mL | |

1、根据实验需要选择合适的溶剂配制储备液 (母液)：对于大多数产品，InvivoChem推荐用DMSO配置母液 (比如：5、10、20mM或者10、20、50 mg/mL浓度），个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;
2、如果您找不到您想要的溶解度信息，或者很难将产品溶解在溶液中，请联系我们;
3、建议使用下列计算器进行相关计算（摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等）;
4、母液配好之后，将其分装到常规用量，并储存在-20°C或-80°C，尽量减少反复冻融循环。
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)。如该浓度超过该批次药物DMSO溶解度，请首先与我们联系。
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 ddH2O，混匀澄清。
(1) 请确保溶液澄清之后，再加入下一种溶剂 (助溶剂) 。可利用涡旋、超声或水浴加热等方法助溶；
(2) 一定要按顺序加入溶剂 (助溶剂) 。
