By affecting the absorption, distribution, metabolism and elimination of drug compounds, various drug delivery technologies improve the therapeutic effect at the intended site of action while minimizing possible adverse effects.
Functions of Drug Delivery Systems
- Controlled release of drugs. With the development of technology, controlled release technologies are now able to achieve not only slow release of drugs, but also more precise and intelligent regulation of the space, time and release profile of drugs.
- Drug targeting. Targeted drug is to make the drug aim at specific lesion sites and form a relatively high concentration locally to reduce the damage to normal tissues and cells.
- Enhance the water solubility and stability of drugs, and regulate drug metabolism time.
- Promote drug absorption and passage through biological barriers.
