Three methods for examining drug-drug interactions were compared to understand advantages and disadvantages of each: ePocrates; Interact; The Mount Sinai multiple source for the evaluation of drug-drug interactions (MS). ePocrates is a commonly employed software system utilized in a hand held computer, the PalmPilot. Interact is on a CD-ROM, and promoted by the American Psychiatric Association Press. The MS system was developed by the authors and utilizes six separate references sources to ascertain the presence and significance of drug-drug interactions. Commonly prescribed neurology and psychotropic medication interactions were compared using the three systems. ePocrates did not list the significance level of the interaction, e.g., (major, moderate, minor), often did not include a mechanism of action, and several commonly employed medications were not included. It did permit examining several drugs at the same time, and was easily carried on the person of the physician. Interact often contained old references, several drugs were not included, was not adapted to a hand held computer format, and had no update since 1999. The MS system listed level of significance, provided mechanism of action, and advice to the practitioner including recommendations. It is not portable, requiring a laptop or desk top computer or hard copy, and only searches one drug at a time. It is hoped that the advantages of each of these three systems may be incorporated into systems of the future.
