Intestinal alkalization as a possible preventive mechanism in irinotecan (CPT-11)-induced diarrhea.
The therapeutic efficacy of irinotecan (CPT-11), a DNA topoisomerase inhibitor, is often limited by the induction of severe late-onset diarrhea. This prodrug and its active metabolite, 7-ethyl-10-hydroxy-camptothecin (SN-38), have a labile alpha-hydroxy-lactone ring that undergoes pH-dependent reversible hydrolysis. At physiological pH and higher, equilibrium favors the less toxic carboxylate f...
متن کاملIrinotecan hydrochloride (CPT-11) in dialysis patients with gastrointestinal cancer.
We investigated changes in drug disposition and toxicities with CPT-11 in 15 dialysis patients with gastrointestinal cancers to clarify whether CPT-11 could be administered safely in such patients. For comparison, the same parameters were also investigated in 10 cancer patients not undergoing dialysis. Items investigated included (1) plasma concentrations of SN-38, SN-38G and CPT-11 at 0, 1, 12...
متن کاملIrinotecan (CPT-11) metabolism and disposition in cancer patients.
The objective of this study was to determine the metabolic fate and disposition of the antitumor camptothecine derivative irinotecan (CPT-11). Ten patients with histological proof of malignant solid tumor received 200 mg/m2 CPT-11 as a 90-min i.v. infusion, followed by a 1.5-h i.v. infusion of cisplatin (60 or 80 mg/m2). Plasma, urine, and feces were collected for 56 h and analyzed by a specifi...
متن کاملSubstantial activity of budesonide in patients with irinotecan (CPT-11) and 5-fluorouracil induced diarrhea and failure of loperamide treatment.
BACKGROUND Diarrhea is one of the most disturbing effects of chemotherapy, affecting quality of life on the one hand and limiting applicable doses on the other. Irinotecan (CPT-11) and 5-fluorouracil (5-FU) are associated with an elevated risk of developing severe diarrhea. Standard therapy consists of high-dose loperamide, but is associated with frequent failure. Other therapeutic regimens are...
