Description
技术领域
本发明属于医药技术领域,具体涉及塞来昔布与厄贝沙坦按摩尔比1∶1结合形成的塞来昔布厄贝沙坦共无定形物及其制备方法。
背景技术
塞来昔布(CX),化学名称是4-[5-(4-苯甲基)-3-(三氟甲基)-1氢-1-吡唑-1-基]本磺酰胺,属于非甾体类抗炎药(NSAIDs),用于治疗风湿性关节炎、骨关节炎,多种发热和各种疼痛症状的缓解,其对环氧合酶2(cox-2)的抑制作用是cox-1的400倍。塞来昔布呈长针状晶体,导致其堆密度低,可压性较差等,使其很难制备成理想固体剂型。而且Cx属于BCSII的弱酸性药物,pKa为11.1,在水中几乎不溶,口服后生物利用度较低,可通过改善其溶解性改善其吸收。
厄贝沙坦(IBS),化学名称是2-丁基-3-4-2-(1H-四唑-5-基)苯基苄基-1,3-二氮杂螺-4.4壬-1-烯-4-酮,是一类口服有效的高选择性的血管紧张素II受体拮抗剂,临床用于治疗高血压及II型糖尿素病中的原发性高血压及肾脏疾病的药物。IBS属于BCS II类药物,在水中几乎不溶,口服生物利用度极低,可通过改善其溶解性使其吸收得到较大程度的改善。
类风湿关节炎和高血压病虽是不同系统的疾病,却在中老年人群中时常共存。我们通过大量研究,发现可以将塞来昔布与厄贝沙坦两种药物制成一种共无定形物,达到同时治疗关节炎和高血压的目的,提高患者的顺应性,这种共无定形物中塞来昔布和厄贝沙坦的溶解度均得到显著的提高。
