生物利用度(Bioavailabilty)同一个药物以不同的制剂给与时,往往会产生药理效应的强度、起效时间和持续时间的差异。对于产生全身作用的药物,只有被吸收入血液循环才能产生药效。因此制剂的质量好坏,不仅与药物含量有关,还与制剂中的药物能否被机体吸收有关。生物利用度 Bioavailability (Bioavailabilty) When the same drug is given in different formulations, the intensity of the pharmacological effect, the difference between the onset and the duration of the effect, often results. For drugs that produce systemic effects, they can only be eaten when they are absorbed into the bloodstream. Therefore, the quality of preparation is good or bad, not only with the drug content, but also with the preparation of the drug can be absorbed by the body. bioavailability
