Pridinol is a muscle relaxant drug used to treat muscle spasms and stiffness. However, like any other drug, it may contain impurities that can affect its efficacy, stability, and safety. Pridinol impurities are unwanted or unintended substances that may result from the manufacturing, storage, or transportation of the drug. These impurities may include degradation products, residual solvents, or other contaminants that can potentially harm patients' health. It is therefore crucial for pharmaceutical companies to monitor and control the levels of Pridinol impurities in their products to ensure their safety and effectiveness.
