Rifampicin (Rifadin, Rimactane)
Other Medications · Approved since 1971
Description
Rifampicin is a broad-spectrum antibiotic belonging to the rifamycin class that is used as part of oral antibiotic bowel preparation protocols prior to left-sided colorectal cancer surgery. This antimicrobial agent helps reduce bacterial load in the colon when combined with mechanical bowel preparation, potentially decreasing the risk of surgical site infections and anastomotic complications. Rifampicin's use in this perioperative setting represents supportive care aimed at optimizing surgical outcomes rather than direct cancer treatment.
Mechanism of Action
Rifampicin inhibits bacterial RNA synthesis by binding to the beta subunit of bacterial DNA-dependent RNA polymerase, preventing transcription initiation. This mechanism effectively reduces gram-positive and some gram-negative bacterial populations in the gastrointestinal tract when used as part of preoperative bowel preparation protocols.
