R278474 对所有研究的单突变体和双突变体 (EC50=0.1-2.0 nM) 以及 HIV-1 野生型 (EC50=0.4 nM) 均有效[1]。 R278474（10-5000 nM；30 d）在 30 天的过程中，没有看到野生型 HIV-1 在 1 μM 浓度上突破的迹象 [1]。在抑制浓度 (EC50) 低于 1 nM 时，R278474 可抑制 81% 的临床分离株（约 1200 种重组临床分离株），在 EC50 低于 10 nM 时抑制 94% [1]。对于野生型 HIV-1 M 成分分离株，TMC278 具有亚纳摩尔 EC50 值 (0.07–1.01 nM) [2]。

用 R278474（10-160 mg/kg；口服 1 个月）治疗的大鼠没有表现出任何异常作用，但较高剂量水平下肝脏重量增加和物种特异性甲状腺肥大除外[1]。 R278474 (iv) 的 AUCinf 值范围为大鼠 3.1 μg h/mL (4 mg/kg)、狗 8.7 μg h/mL (1.25 mg/kg)、猴子 1.4 μg h/mL (1.25 mg/kg) ，和 44 μg h/mL (1.25 mg/kg) 在兔子中。消除半衰期范围从大鼠的 4.4 小时到狗的 31 小时[1]。在大鼠和狗中，R278474 (po) 的半衰期分别为 2.8 和 39 小时，口服生物利用度分别为 32% 和 31%[1]。

Effects During Pregnancy and Lactation
◉ Summary of Use during Lactation
Limited information indicates that maternal rilpivirine doses of 25 mg daily produce low levels in milk and infant serum. Until more data become available, an alternate drug may be preferred, especially while nursing a newborn or preterm infant. Achieving and maintaining viral suppression with antiretroviral therapy decreases breastfeeding transmission risk to less than 1%, but not zero. Individuals with HIV who are on antiretroviral therapy with a sustained undetectable viral load and who choose to breastfeed should be supported in this decision. If a viral load is not suppressed, banked pasteurized donor milk or formula is recommended.

Rilpivirine hydrochloride is a hydrochloride obtained by reaction of rilpivirine with one equivalent of hydrochloric acid. Used for treatment of HIV. It has a role as a prodrug, a HIV-1 reverse transcriptase inhibitor and an EC 2.7.7.49 (RNA-directed DNA polymerase) inhibitor. It contains a rilpivirine(1+).
Rilpivirine (brand names: Edurant and Edurant PED) is a prescription medicine approved by the U.S. Food and Drug Administration (FDA) for use with other HIV medicines for the treatment of HIV infection in adults and children 2 years of age and older who weigh at least 31 lb (14 kg) who have never taken HIV medicines before and who meet certain requirements, as determined by a health care provider.
Rilpivirine (brand name: Edurant) is also FDA-approved for use with oral cabotegravir (brand name: Vocabria) for the short-term treatment of HIV infection in adults and children 12 years of age and older who weigh at least 77 lb (35 kg) and who meet certain requirements, as determined by a health care provider.
A diarylpyrimidine derivative and REVERSE TRANSCRIPTASE INHIBITOR with antiviral activity against HIV-1 that is used in the treatment of HIV INFECTIONS. It is also used in combination with other ANTI-HIV AGENTS, since ANTIVIRAL DRUG RESISTANCE emerges rapidly when it is used alone.

Drug Indication
Edurant, in combination with other antiretroviral medicinal products, is indicated for the treatment of human immunodeficiency virus type 1 (HIV‑1) infection in antiretroviral treatment‑naïve patients 12 years of age and older with a viral load ≤ 100,000 HIV‑1 RNA copies/ml. , , As with other antiretroviral medicinal products, genotypic resistance testing should guide the use of Edurant. ,

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;
