Safety of capecitabine: a review

Abstract

Importance of the field: Fluoropyrimidines, in particular 5-fluorouracil (5-FU), have been the mainstay of treatment for several solid tumors, including colorectal, breast and head and neck cancers, for > 40 years.

Areas covered in this review: This article reviews the pharmacology and efficacy of capecitabine with a special emphasis on its safety.

What the reader will gain: The reader will gain better insight into the safety of capecitabine in special populations such as patients with advanced age, renal and kidney disease. We also explore different dosing and schedules of capecitabine administration.

Take home message: Capecitabine is an oral prodrug of 5-FU and was developed to fulfill the need for a more convenient therapy and provide an improved safety/efficacy profile. It has shown promising results alone or in combination with other chemotherapeutic agents in colorectal, breast, pancreaticobiliary, gastric, renal cell and head and neck cancers. The most commonly reported toxic effects of capecitabine are diarrhea, nausea, vomiting, stomatitis and hand-foot syndrome. Capecitabine has a well-established safety profile and can be given safely to patients with advanced age, hepatic and renal dysfunctions.
