Brief Summary:
A total of 440 patients meeting enrollment criteria with a primary episode of C. Difficile Infection (CDI) will be enrolled across 3 sites. The total study time period for study procedures followed by clinical monitoring is anticipated to be about 24 months (biomarker assays and other analyses may be completed after the 24 month time period). All participants will receive oral vancomycin under the care of their physician. After consenting to participate in the study, participants will be randomized to receive either misoprostol (200 mcg po BID) or matching placebo for 14 days. Participants will be monitored for a total time-period of approximately 9 weeks with the goal of monitoring for recurrence of CDI during an 8-week follow-up period from the time that the course of vancomycin is completed. Patients will have blood and stool samples (or rectal swabs if participants are unable to provide a stool sample) collected throughout the study to assess adherence, biomarkers, and to confirm recurrence of CDI (if necessary).

Drug Information available for: Misoprostol

Arm Intervention/treatment
Experimental: Study Drug (Misoprostol) Drug: Misoprostol 100Mcg Tab
Two 100mcg capsules twice per day

Placebo Comparator: Placebo Other: Placebo
Two capsules twice per day

Primary Outcome Measures :
  1. Rate of clinical recurrence of CDI in patients aged 50 years or older during the first 8 weeks after vancomycin therapy is stopped. [ Time Frame: 8 weeks ]
    Rate of recurrence among misoprostol treated participants will be compared with that of placebo treated participants to determine if misoprostol has efficacy in preventing rCDI. rCDI will be defined as people who meet criteria for CDI in the 8 week follow-up period.

Secondary Outcome Measures :
  1. Number of recurrences during the follow-up period [ Time Frame: 8 weeks ]
    Number of recurrences during the follow-up period (for those who have a first recurrence during the follow-up time period)

  2. Time to resolution of diarrhea [ Time Frame: 8 weeks ]
    Time to resolution of diarrhea (TTROD; for those with recurrence)
