Pharmacokinetics of Apixaban in Patients With Short Bowel Syndrome Requiring Long Term Parenteral Nutrition
Short bowel syndrome (SBS) is defined as a loss of function of the small intestine resulting in a malabsorptive disorder. In SBS, oral drug absorption may be altered due to extensive intestinal resection. It remains unclear to what extent apixaban exposure is impacted in SBS.Therefore this study tries to investigate the pharmacokinetics (PK) of apixaban in adult patients with SBS requiring long-term parenteral nutrition (PN).
• patients with SBS (small bowel length of <2m after Treitz ligament) on long term (>3 months) PN or fluids who are anticoagulation and teduglutide naive
• patients with SBS (small bowel length of <2m after Treitz ligament) on long term (>3 months) PN or fluids who are teduglutide naive and who are already taking apixaban 2,5 mg or 5 mg twice daily for ≥ 4 days
• healthy individuals without history of GI resections or other conditions associated with impaired absorption, who are anticoagulation naive
• patients without history of gastrointestinal resections or other conditions associated with impaired absorption (= controls), who are already taking apixaban 2,5 mg or 5 mg twice daily for ≥ 4 days
