title: Possible drug-associated pancreatitis after paclitaxel-cremophor administration.
abstract: Paclitaxel, a relatively new antineoplastic agent, is associated with numerous side effects, including two reported cases of pancreatitis. Our patient also developed paclitaxel-associated pancreatitis. Several companion drugs, including steroids, diphenhydramine, histamine2 blockers, serotonin type 3 antagonists, and other chemotherapeutic agents administered with paclitaxel, must be considered as possible causes of pancreatitis. In addition, paclitaxel is a hydrophobic agent that requires a vehicle, cremophor (CrEL), for solubility. Intravenous cyclosporine also requires CrEL and has been associated with pancreatitis. In the cerulein-induced pancreatitis rat model, paclitaxel with dimethyl sulfoxide as a vehicle prevents pancreatitis, suggesting that another causal agent is responsible. Animal studies of CrEL as a single agent may be required to settle this question, but for now, awareness that paclitaxel may be associated with pancreatitis may lead to earlier treatment of this potentially fatal complication.
