Clostridioides difficile bacteria can cause life-threatening diarrhea and colitis owing to limited treatment options and unacceptably high recurrence rates among infected patients. This necessitates the development of alternative routes for C. difficile treatment. Drug repurposing with new indications represents a proven shortcut. Here, we present a refined focus on 16 FDA-approved drugs that would be suitable for further development as potential anti-C. difficile drugs. Of these drugs, clinical trials have been conducted on five currently used drugs; however, ursodeoxycholic acid is the only drug to enter Phase IV clinical trials to date. Thus, drug repurposing promotes the study of mechanistic and therapeutic strategies, providing new options for the development of next-generation anti-C. difficile agents.

Diarrhea associated with enteric infections, gut inflammation, and genetic defects poses a major health burden and results in significant morbidity and mortality. Impaired fluid and electrolyte absorption and/or secretion in the intestine are the hallmark of diarrhea. Electroneutral NaCl absorption in the mammalian GI tract involves the coupling of Na/H and Cl/HCO exchangers.

Introduction: We aimed to determine the impact of prior antimicrobial treatment on recurrent Clostridioides difficile infection (CDI) based on days of antibiotic spectrum coverage (DASC) and predict the risk of recurrence to guide the selection of appropriate initial therapeutic agents.
Methods: We assessed the antimicrobial treatment administered to 195 patients with a history of CDI for 28 days before testing positive for C. difficile using DASC and illness severity using ATLAS scores.
