Ipratropium Impurities are impurities that may be present in Ipratropium, a medication used to treat bronchospasm associated with chronic obstructive pulmonary disease (COPD). These impurities can include residual solvents, degradation products, and other impurities that may have been introduced during the manufacturing process. It is important to monitor and control the levels of these impurities to ensure the safety and efficacy of the medication. Analytical methods such as HPLC and GC are commonly used to detect and quantify these impurities.
