Amikacin is an aminoglycoside antibiotic used to treat bacterial infections. During the manufacturing process, impurities may be introduced into the drug substance, which can affect its safety and efficacy. Amikacin impurities are typically identified and quantified using analytical methods such as high-performance liquid chromatography (HPLC) or gas chromatography (GC). Understanding and controlling the levels of impurities in amikacin is essential to ensuring its quality and safety for use in patients.
