Explanation

Also known as a drug delivery system. A system that can control and regulate the release rate and delivery mode of drugs (including chemical drugs, peptide drugs, nucleic acid drugs, etc.). Usually composed of drugs and carriers, the purpose is to release drugs into specific tissues, organs, cells, and organelles at designed doses and in specific ways, in order to achieve optimal therapeutic effects. Compared with conventional administration, its main advantages include maintaining a stable drug level within the allowable range of treatment, prolonging the duration of action, reducing the frequency of administration, reducing the peak valley phenomenon of blood drug concentration, reducing toxic side effects, reducing drug resistance, and increasing drug stability. It is particularly suitable for some drugs or biological agents with significant toxic side effects (such as anticancer drugs) or easily inactivated (such as protein and peptide drugs). It has a variety of forms, including nano and micro particles, gel, fiber, film, etc. The drug release system can be administered through different routes, such as injection, oral administration, transdermal, inhalation, etc.
