近年来国内外文献对药物固体剂型释放性能的报导较多,认为它和药物的吸收密切相关。对于主药溶速较慢的药剂,体外释放度的测定可用来反映生物利用度,作为改进剂型或工艺的一项依据。但有关中药口服固体剂型释放性能的报导却很少。 In recent years, reports on the release properties of solid dosage forms of pharmaceuticals have been reported in domestic and foreign literatures, and it is believed that it is closely related to the absorption of drugs. For agents with slower main drug dissolution rates, in vitro release assays can be used to reflect bioavailability as a basis for improving the dosage form or process. However, there are few reports on the release properties of Chinese oral solid dosage forms.
