Mechanism of action

OM-85 BV is composed of lysates from eight common respiratory pathogens (Streptococcus pneumoniae, Streptococcus pyogenes, Staphylococcus aureus, Klebsiella pneumoniae, Klebsiella ozaenae, Haemophilus influenzae, Branhamella catarrhalis, and Neisseria catarrhalis). It stimulates mucosal and systemic immunity through pattern recognition receptors, promoting the production of immunoglobulins and enhancing phagocytic activity. This broad immune activation reduces the incidence and severity of recurrent respiratory infections.
