PIDOTIMOD belongs to the group of medications called ‘immunostimulants’ primarily used to treat respiratory system infections. Respiratory tract infection (RTI) is any infectious disease of the upper or lower respiratory tract. PIDOTIMOD contains Pidotimod as the active ingredient. It is an immunostimulant that works by modulating the immune system to trigger a protective response against bacteria or viruses that cause recurrent airway infections. This boosts immunity against these infections.
