Hypersensitivity and infusion-site adverse events with intravenous fosaprepitant after anthracycline-containing chemotherapy: a retrospective study.

ABSTRACT

AIM: Fosaprepitant, an intravenous neurokinin-1 receptor antagonist for chemotherapy-induced nausea and vomiting, contains polysorbate 80, which is associated with infusion-site adverse events (ISAEs) and hypersensitivity systemic reactions (HSRs). This study investigated ISAEs/HSRs following fosaprepitant with anthracycline-containing chemotherapy. PATIENTS & METHODS: This retrospective chart review noted ISAEs/HSRs following the anthracycline doxorubicin+cyclophosphamide and a three-drug fosaprepitant regimen, via peripheral line. RESULTS: 35/127 patients (28%) developed ISAEs/HSRs with chemotherapy and antiemetic therapy 32 developed 137 individual ISAEs, primarily erythema, pain and catheter-site swelling; 16 developed 50 individual HSRs, primarily edema/swelling, erythema or dermatitis (no anaphylaxis). CONCLUSION: Fosaprepitant is associated with a significant ISAE/HSR rate following anthracycline-containing chemotherapy via peripheral line. Polysorbate 80-free intravenous neurokinin-1 receptor antagonist may provide a safer chemotherapy-induced nausea and vomiting prophylaxis option.
