PEG (Polyethylene glycol) is a polymer widely used in the medical field. PEG has good solubility and biocompatibility and can be used to prepare drugs, medical supplies and medical equipment. Its low toxicity and immunogenicity make it an excellent drug carrier and oral drug absorption enhancer. PEG binds closely to water molecules and is not easily metabolized in the body, thereby prolonging the residence time of drugs in the body and increasing drug efficacy.
PEG has a wide range of applications. In addition to pharmaceutical preparation, it can also be used to manufacture medical equipment and medical testing reagents. For example, in the manufacture of medical devices such as artificial joints and heart stents, PEG can improve the biocompatibility, antioxidant and anti-thrombotic properties of the material, thereby extending its service life. In addition, PEG can also be used to prepare enzyme analysis reagents and antibody purification reagents, which can greatly improve the accuracy and sensitivity of biological detection.
Although PEG plays an important role in the medical field, its presence may also cause some side effects. When using PEG drugs, adverse reactions such as digestive system reactions, liver damage, and kidney damage often occur. At the same time, long-term use of PEG may also cause blood lesions, neurotoxicity and immune reactions. Therefore, when using PEG, it is necessary to follow the recommendations of medical experts and conduct personalized treatment based on the patient's specific situation to ensure the patient's safety and health.
