METHOD AND APPARATUS FOR PREPARING A MEDICINAL SUBSTANCE

Provided are a system and method for presenting information related to a drug dilution. A computer memory stores a drug database with a plurality of drug entries, each of which includes an identification and concentration of a drug stored in an originating container. A reader is operable to read a barcode associated with the drug identifier of the originating drug container and the concentration and/or dose and volume of the drug in the container. A user selects or enters a desired drug preparation that may include one or more preparations of the originating drug requested for administration to a patient. A computer processor interprets the concentrate signal, identifies the concentration of the originating drug based on content included in the drug database, and determines a recipe to be presented to the user for preparing the drug including any required dilutions.
