Problems solved by technology

[0004] ①Slow disintegration rate of solid oral preparations (such as tablets, capsules, etc.) and low release rate of active ingredients
Such a long time is undoubtedly not helpful for the rapid release of the active ingredients of the drug
[0005] ②First-pass effect problem
Due to its own reasons, oral preparations are mostly absorbed in the gastrointestinal tract, which is prone to first-pass effect, which reduces the active ingredients
