Cetirizine Impurities

Cetirizine is a second-generation antihistamine widely used to relieve allergy symptoms such as sneezing, runny nose, and itching associated with hay fever, urticaria, and other allergic conditions. It works by selectively blocking histamine H1 receptors without causing significant drowsiness, making it a preferred choice over first-generation antihistamines. Maintaining the pharmaceutical quality of Cetirizine is essential to ensure patient safety, therapeutic effectiveness, and compliance with regulatory standards. Impurity profiling is crucial in detecting and controlling unwanted substances that may arise during manufacturing, storage, or degradation. Here are some of its known impurities listed below.
