In vitro comparison test for chemical solid oral generic drugs administered by nasogastric tubes / 国际药学研究杂志

ABSTRACT

At present, the dosage and administration items in the marketing instructions of some oral solid brand drugs approved in China include related contents for administration via nasogastric tube. In order to achieve consistency with the original drugs in quality and efficacy, the generic drugs investigators should confirm whether the generic drugs and the original drugs have the same in vitro characteristics under the conditions of administration by nasogastric tube. The purpose is to eliminate the clinical risks brought by the way of administration. This article summarizes the experimental design and evaluation points for the in vitro comparative study of the solid oral generic drugs which can be administered by nasogastric tube, while referring to the individual drug guidelines issued by FDA and the related literature published, so as to provide a reference for the technical system construction for the consistency evaluation of oral solid dosage forms.
