Publication number: 20210259253Abstract: Systems and methods for sterilizing iodophor compositions are described. In some cases, the iodophor composition comprises a complex comprising iodine and a polymer (i.e., an iodine-polymer complex). The iodine-polymer complex may be polyvinylpyrrolidone iodine (also referred to as “povidone-iodine” or “PVP-I”) or iodine povacrylex. Methods are described for heating an initial iodophor composition to produce a sterilized iodophor composition. The resulting sterilized iodophor composition may have a relatively high assurance of sterility (e.g., a sterility assurance level of 10?3 or less, 10?6 or less). In some cases, heating the initial iodophor composition comprises exposing at least a portion of a container containing the initial iodophor composition to a heated liquid. In certain cases, the heated liquid is part of a moving liquid stream (e.g., a cascading waterfall stream produced by a cascading waterfall sterilizer).Type: ApplicationFiled: February 19, 2021Publication date: August 26, 2021Applicant: CareFusion CorporationInventors: Nathan Sieracki, Christopher McGinley, Moises Ortiz
