Abstract:

BACKGROUND: Polylactic acid copolymer composite sustained-release drug materials can reduce the toxic side effects of drugs, extend the action time and improve the effect of the drugs, and it is the hot spot of the drug research recently.
OBJECTIVE: To identify the characteristics and experimental application of various polylactic acid copolymer composite sustained-release drug materials.
METHODS: Different types of drugs were copolymerized with the polylactic acid to form the polylactic acid copolymer composite sustained-release drug materials, and the drug release characteristics and the treatment effect of various polylactic acid copolymer composite sustained-release drug materials in the animal experimental studies were analyzed.
RESULTS AND CONCLUSION: Studies have found that many types of drug can be copolymerized with the polylactic acid and form the polylactic acid copolymer composite sustained-release drug material system, including the anti-tumor drugs, anti-bacterial drugs, anti-viral drugs, anti-tuberculosis drugs, drugs for the prevention and treatment of cardiovascular and cerebrovascular diseases and the metabolic drugs. The drugs above can prolong the action time, effectively stabilize the plasma concentration, obtain the role of targeted therapy and significantly improve the treatment effect after copolymerized with the polylactic acid and form the polylactic acid copolymer composite sustained-release drug material system.
