Application of propylene glyco (PG) in medicine
Release time:
2024-06-12
The main role of propylene glycol in injections is to act as a solvent, helping to improve the solubility and stability of the drug, thereby increasing the bioavailability of the drug.
1. Improve drug solubility: Injections have higher requirements on drug solubility, especially for some drugs with poor water solubility and good oil solubility. Since propylene glycol has good solubility, it can keep these drugs in injections at a higher content and improve the solubility of the drugs.
2. Enhance drug stability: In addition to good solubility, propylene glycol also has strong stability, which can prevent the drug from deteriorating due to chemical reactions or physical effects and maintain the stability of the drug.
3. Improve drug bioavailability: Propylene glycol has a small molecule and can easily pass through biological membranes, which can improve the bioavailability of drugs and exert better efficacy.
The use of propylene glycol in injections can improve the solubility and stability of the drug, thereby improving the bio-availability of the drug and giving full play to its efficacy. However, although propylene glycol is a widely used auxiliary ingredient, it should still be used under the guidance of a doctor to ensure safety while ensuring drug efficacy.
