Infor share: New drug carrier material

It has been a difficult problem for the biomedicalfield to develop new drug carriers to improve oral drug’s bioavailability anddrug targeting. By oral administration in mice experiments, tracking andmonitoring anionic G6.0 PAMAM-COOH transport changes in the body through themouth, we can get the following conclusions: (1) PAMAM-COOH as a drug carrierin mice body is stable. (2) PAMAM-COOH can enter mice through the oraladministration, while maintaining the biological stability it can also enterthe body circulation, distribute to a certain organ with the targeting. (3)1mg/kg PAMAM-COOH taken by mouth has no drug toxicity, and thereis no difference in the state of growth with normal mice. Based onthis, we can determine PAMAM as a drug carrier has huge potential applicationsto improve oral drug’s bioavailability and drug targeting.
