Oritavancin Disease Interactions

There are 4 disease interactions with oritavancin:

Moderate

Antibiotics (Includes Oritavancin) ↔ Colitis

Moderate Potential Hazard, Moderate plausibility

Applies to: Colitis/Enteritis (Noninfectious)

Pseudomembranous colitis has been reported with most antibacterial agents and may range in severity from mild to life-threatening, with an onset of up to two months following cessation of therapy. Antibiotic therapy can alter the normal flora of the colon and permit overgrowth of Clostridium difficile, whose toxin is believed to be a primary cause of antibiotic- associated colitis. The colitis is usually characterized by severe, persistent diarrhea and severe abdominal cramps, and may be associated with the passage of blood and mucus. The most common culprits are clindamycin, lincomycin, the aminopenicillins (amoxicillin, ampicillin), and the cephalosporins. Therapy with broad-spectrum antibiotics and other agents with significant antibacterial activity should be administered cautiously in patients with a history of gastrointestinal diseases, particularly colitis. There is some evidence that pseudomembranous colitis, if it occurs, may run a more severe course in these patients and that it may be associated with flares in their underlying disease activity. The offending antibiotic(s) should be discontinued if significant diarrhea occurs during therapy. Stool cultures for Clostridium difficile and stool assay for C. difficile toxin may be helpful diagnostically. A large bowel endoscopy may be considered to establish a definitive diagnosis in cases of severe diarrhea.

Moderate

Oritavancin (Includes Oritavancin) ↔ Bleeding

Moderate Potential Hazard, Moderate plausibility

Applies to: Coagulation Defect

Oritavancin has been shown to artificially prolong prothrombin time (PT) and international normalized ratio (INR) for up to 12 hours, making the monitoring of the anticoagulation effect of warfarin unreliable up to 12 hours after an oritavancin dose. Oritavancin has no effect on the coagulation system in vivo. Care should be taken when administering this agent to patients at risk for bleeding and they should be monitored for bleeding if concomitantly receiving warfarin. It is recommended to consider a non-phospholipid dependent coagulation test such as a Factor Xa (chromogenic) assay or an alternative anticoagulant not requiring aPTT monitoring for those patients requiring aPTT monitoring within 5 days of oritavancin dosing.

Moderate

Oritavancin (Includes Oritavancin) ↔ Hepatic Impairment

Moderate Potential Hazard, Moderate plausibility

Applies to: Liver Disease

No dosage adjustment of oritavancin is needed in patients with mild or moderate hepatic impairment. Care should be taken when administering oritavancin to patients with severe hepatic impairment as the pharmacokinetics of this agent have not been studied.

Moderate

Oritavancin (Includes Oritavancin) ↔ Renal Impairment

Moderate Potential Hazard, Moderate plausibility

Applies to: Renal Dysfunction

No dosage adjustment of oritavancin is needed in patients with mild or moderate renal impairment. Care should be taken when administering oritavancin to patients with severe renal impairment as the pharmacokinetics of this agent have not been evaluated. Oritavancin is not removed from blood by hemodialysis.

Drug Interaction Classification

The classifications below are a general guideline only. It is difficult to determine the relevance of a particular drug interaction to any individual given the large number of variables.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
