Problems solved by technology

PNS is extremely water-soluble, and has poor permeability from the gastrointestinal tract to the mucous membrane. The strong acid environment in the stomach and the strong alkali environment in the intestinal tract also have a strong degradation effect on the drug, and the active monomers are very easy to be gastrointestinal enzymes and intestinal tract. Bacterial metabolism, thus leading to low bioavailability of oral formulations, where Rb 1 The oral absolute bioavailability of Rg1 is only 4.35%, the oral bioavailability of Rg1 is 18.40%, and it is eliminated quickly in the blood
Moreover, most of the efficacy of PNS comes from the original drug, rather than the product after metabolism or degradation, so oral administration is not a suitable route of administration for PNS.
