NCT05320068

Brief Summary

A phase III randomized clinical trial in proportion 2:1 in favor of oral vancomycin (experimental treatment), multicentric, national, double-blinded, controlled with placebo. The main objective is to evaluate the effectiveness of treatment with oral vancomycin to reduce the incidence of Clostridioides difficile infection (CDI) in patients who suffered previous CDI and who need further hospitalization and treatment with systemic antibiotic therapy in the 90 days after the first CDI.
