Lacidipine is a calcium channel blocker used in the treatment of hypertension. However, during its synthesis, some impurities may be formed. These impurities are unwanted by-products that can affect the quality, safety, and efficacy of the drug. Therefore, it is important to identify and control these impurities to ensure the purity and stability of the final product. Some of the potential impurities in Lacidipine include related substances, degradation products, and residual solvents. Analytical methods such as HPLC and GC are used to detect and quantify these impurities. The limits for impurities are set by regulatory agencies to ensure the safety and efficacy of the drug.
