本发明属于药物组合物研发技术领域,具体是涉及一种含托法替尼药学上可接受的盐的药物组合物、制剂及应用。The invention belongs to the technical field of research and development of pharmaceutical compositions, in particular to a pharmaceutical composition, preparation and application containing a pharmaceutically acceptable salt of tofacitinib.
背景技术Background technique
托法替尼(Tofacitinib),化学名为3-{(3R,4R)-4-甲基-3-[甲基(7H-吡咯并[2,3-d]嘧啶-4-基)氨基]哌啶-1-基}-3-氧代丙腈:

托法替尼是一种JAK抑制剂,可用于器官移植,异种移植,狼疮,多发性硬化症,类风湿性关节炎,牛皮癣,银屑病关节炎,1型糖尿病以及其他类型糖尿病,癌症,哮喘,特应性皮炎(Atopic Dermatitis,又称特异性皮炎),自身免疫性甲状腺疾病,溃疡性结肠炎,克罗恩氏病,阿尔茨海默氏病,白血病和其他需要免疫抑制的适应症的疗法的免疫抑制剂。Tofacitinib is a JAK inhibitor indicated for organ transplantation, xenotransplantation, lupus, multiple sclerosis, rheumatoid arthritis, psoriasis, psoriatic arthritis, type 1 diabetes and other types of diabetes, cancer, Asthma, Atopic Dermatitis (also known as atopic dermatitis), autoimmune thyroid disease, ulcerative colitis, Crohn's disease, Alzheimer's disease, leukemia and other indications requiring immunosuppression of immunosuppressive therapy.
目前枸橼酸托法替尼已经在美国获批。以片剂形式销售,每片含8mg枸橼酸托法替尼,每日两次,用以治疗类风湿关节炎等。目前研究证明,口服枸橼酸托法替尼有较多副作用。例如上呼吸道感染、感冒、头痛等症状。目前学界已有提出使用局部制剂来避免口服所造成的副作用。例如专利文献CN103459394B公开了游离态托法替尼制作的油膏用于治疗牛皮癣。专利文献TW201940174A公开了枸橼酸托法替尼制作的局部配方用于治疗白癜风与特应性皮炎。专利文献CN103459394B中提出以游离态托法替尼制作油膏,在实施例15中,游离态托法替尼的稳定性较差,在40℃储存4周,纯度仅为97.3%。Tofacitinib citrate is currently approved in the United States. Sold in tablet form, each tablet contains 8 mg of tofacitinib citrate twice daily for the treatment of rheumatoid arthritis, among others. Current studies have shown that oral tofacitinib citrate has many side effects. Such as upper respiratory tract infection, cold, headache and other symptoms. At present, the academic community has proposed to use topical preparations to avoid the side effects caused by oral administration. For example, patent document CN103459394B discloses that an ointment made from free state tofacitinib is used for the treatment of psoriasis. Patent document TW201940174A discloses a topical formulation made of tofacitinib citrate for the treatment of vitiligo and atopic dermatitis. Patent document CN103459394B proposes to use free state tofacitinib to make ointment. In Example 15, free state tofacitinib has poor stability, and the purity is only 97.3% when stored at 40° C. for 4 weeks.
专利文献TW201940174A中,以二甲基亚砜作为其原料药的溶剂使用,使用量在45%,用量较大。二甲基亚砜作为一种常见的万能溶剂,有局部毒性作用和低的全身毒性。二甲基亚砜主要刺激皮肤,产生红肿、灼烧、瘙痒、结垢、引起荨麻疹等(R.C.罗,P.J.舍斯基,P.J.韦勒.药物辅料手册[M].北京:化学工业出版社,2005:256)。In the patent document TW201940174A, dimethyl sulfoxide is used as the solvent of its bulk drug, and the usage amount is 45%, which is relatively large. As a common universal solvent, dimethyl sulfoxide has local toxicity and low systemic toxicity. Dimethyl sulfoxide mainly stimulates the skin, causing redness, burning, itching, scaling, urticaria, etc. (RC Luo, PJ Shesky, PJ Weller. Handbook of Pharmaceutical Excipients [M]. Beijing: Chemical Industry Press , 2005: 256).
考虑专利文献CN103459394B与TW201940174A的局限性,在本领域中需要具有更高保留率、低刺激性、高稳定性的托法替尼外用制剂以治疗自身免疫性疾病。Considering the limitations of patent documents CN103459394B and TW201940174A, topical tofacitinib formulations with higher retention rate, low irritation and high stability are needed in the art to treat autoimmune diseases.

注:其中“皮肤内潴留量(μg/g)”由“皮肤内潴留量(μg/cm2)”转化而来,我们采用的小香猪皮其每平方厘米的皮肤为0.196g。Note: The "skin retention (μg/g)" is converted from the "skin retention (μg/cm2)", and the skin per square centimeter of the pig skin we use is 0.196g.
根据透皮实验数据,B1、B3、B13、B16、C1、C2、C3、C5处方在皮肤内潴留量明显高于枸橼酸托法替尼处方(B4),说明在促渗剂二乙二醇单乙基醚的作用下,对酒石酸托法替尼透过皮肤有明显的促进作用。而与游离态托法替尼的处方E1相比,B1、B3、B13、C1、C3处方在扩散池内药物浓度很低(皮肤内潴留量/透过量比值为50倍以上,E1仅为1.5倍),说明采用二乙二醇单乙基醚作为促渗剂时,离子态托法替尼过度吸收至循环***的风险显著降低,增加了药物使用过程中的安全性。同样的,相比于E1处方,硫酸托法替尼(处方D1)和磷酸托法替尼(处方D2)的皮肤内潴留量/透过量也大幅度提高,其安全性较E1也明显提高。According to the transdermal test data, the skin retention of B1, B3, B13, B16, C1, C2, C3, and C5 formulations was significantly higher than that of tofacitinib citrate formulation (B4), indicating that in the penetration enhancer diethylenediol Under the action of alcohol monoethyl ether, tofacitinib tartrate can significantly promote the penetration of tofacitinib through the skin. Compared with prescription E1 of free tofacitinib, prescriptions B1, B3, B13, C1, and C3 have very low drug concentrations in the diffusion cell (the ratio of retention/permeation in the skin is more than 50 times, and E1 is only 1.5 times). , indicating that when diethylene glycol monoethyl ether is used as a penetration enhancer, the risk of excessive absorption of ionic tofacitinib into the circulatory system is significantly reduced, which increases the safety of the drug during use. Similarly, compared with the E1 prescription, tofacitinib sulfate (formulation D1) and tofacitinib phosphate (formulation D2) have significantly improved skin retention/penetration, and their safety is also significantly improved compared to E1.
