[Stability of 5-fluorouracil-folinic acid mixture: influence of concentrations, container and form of folinic acid].

Since the discovery of the superiority of the combination 5-fluorouracil (5FU)-folinic acid (FA) in comparison to 5FU alone in the treatment of gastrointestinal cancers, the interest of this association has been demonstrated in many other tumors. In the treatment of advanced colorectal carcinoma, FA is usually administered in 1 or 2 h infusion before 5FU. In treatment of other cancers, the two drugs are generally mixed together in the same container and administered as a continuous intravenous infusion over several days.
