Abstract: Sustained release formulation containing tacrolimus or its hydrate is provided. The time (T63.2%) required for 63.2% of the maximum amount of tacrolimus or its hydrate to be dissolved is 0.7 to 15 hours. The time is measured in accordance to the Japanes Pharmacopocia, the 13-th edition, Dissolution Test, No. 2 (Puddles method, 50 rpm) using an aqueous 0.005% hydroxypropyl cellulose solution. This aqueous test solution is adjusted to pH 4.5, accordingly. The formulation further comprises a solid base which is a water-soluble or water-insoluble polymer. The formulation is in the form of a powder, fine powder, granule, tablet or capsule. The formulation is administered to a patient once a day for preventing organ or tissue rejection by transplantation or autoimmune disease. In addition, a solid dispersion composition is provided. The solid dispersion comprises tacrolimus or its hydrate in a mixture containing water-soluble or water-insoluble polymer and an excipient.
Abstract translation: 提供含他克莫司或其水合物的缓释制剂。 最高量的他克莫司或其水合物溶解63.2%所需的时间(T63.2%)为0.7〜15小时。 该时间根据Japanes Pharmacopocia,第13版,溶出度试验,2号(Puddles法,50rpm),使用0.005%羟丙基纤维素水溶液测量。 相应地将该水性测试溶液调节至pH 4.5。 该制剂还包含固体碱,其为水溶性或水不溶性聚合物。 制剂为粉末,细粉,颗粒,片剂或胶囊的形式。 该制剂每天一次施用于患者,以通过移植或自身免疫疾病预防器官或组织排斥反应。 此外,提供了固体分散体组合物。 固体分散体包含他克莫司或其水合物,其含有水溶性或水不溶性聚合物和赋形剂的混合物。
