Formulation,Stability and Compatibility of Iodixanol

Abstract

Iodixanol (Visipaque) is an isotonic, electrolyte-balanced roentgen contrast medium for intravascular use. The patented and well-proven formulation and the rationale for it are described, and the efficacy and safety are documented. The stability of iodixanol is well within the specifications under all relevant conditions, both in glass and polypropylene bottles; the product has a recommended shelf-life of at least 36 months when stored at room temperature and protected from light. Heating to body temperature before use is acceptable and recommendable, and storage at 37°C for 1 month does not jeopardize product quality. Iodixanol has no apparent immediate in vitro incompatibility reactions with drugs often used in connection with roentgen contrast examinations.
