Zesorisaz Tablet is used for supporting immune health in prescribed medical settings. It is primarily used in clinical situations where careful regulation of the immune system is required. By influencing the way immune cells multiply and function, it helps achieve a controlled immune balance and reduces the risk of immune-related complications. Azathioprine works by interfering with purine synthesis, which is essential for DNA formation in rapidly dividing immune cells such as T and B lymphocytes. Through this mechanism, it helps reduce excessive immune activation that may otherwise result in tissue or organ inflammation. This allows physicians to manage conditions that require suppression of immune hyperactivity in a controlled and sustained manner.
