卡马西平(Carbamazepine;简称 CBZ)是治疗癫癎大发作,部分性发作,顽固性癫癎、三叉神经痛的首选药物。据反映,国产CBZ片疗效较差。由于CBZ在胃肠道吸收迅速,几乎完全吸收,因此CBZ的溶出情况将是吸收的关键,而药物吸收速度主要取决于制剂中药物释放速度,故其体外释放度的测试,将能在一定程度上较好地反映其生物利用度,为此我们对不同剂型不同处方的CBZ制剂进行了体外释放度的测试。
Carbamazepine (CBZ) is the first choice for the treatment of seizures, partial seizures, intractable epilepsy and trigeminal neuralgia. It is reported that domestic CBZ film less effective. Since CBZ absorbs rapidly and almost completely in the gastrointestinal tract, the dissolution of CBZ will be the key to absorption, and the rate of drug absorption depends mainly on the rate of release of the drug in the formulation. Therefore, the in vitro release test of CBZ will, to a certain extent To better reflect its bioavailability, for which we have different formulations of different formulations of CBZ formulations in vitro release test.
