Medical Uses
ZINPLAVA (bezlotoxumab), from Merck, is indicated to reduce the recurrence of Clostridioides difficile infection (CDI) in patients 1 year of age and older who are receiving antibacterial drug treatment for CDI and are at high risk for recurrence.
Bezlotoxumab is a monoclonal antibody that binds to and neutralizes C. difficile toxin B, preventing the toxin from damaging intestinal cells and reducing the likelihood of CDI recurrence — it does not treat the active infection itself, which requires antibacterial therapy.
