Flunarizine Impurities refer to the unwanted substances that may be present in Flunarizine drug samples. These impurities can arise due to various factors such as manufacturing processes, storage conditions or degradation over time. It is important to identify and quantify these impurities to ensure the safety and efficacy of the drug. Analytical techniques such as HPLC, GC, and NMR are used to detect and characterize Flunarizine Impurities.
