Özet

Objective: Antimicrobial drugs are frequently used in the intensive care unit (ICU) and may cause drug-drug interactions (DDIs) which change treatment outcomes. This study aims to determine the frequency of potential DDIs (pDDIs) caused by antimicrobial drugs in the ICU, according to two databases, address the differences between these two databases, discuss the clinical significance of pDDIs and investigate their relationship with clinical outcomes. Materials and Methods: This study was designed as a 1-year retrospective cross-sectional study. Patients over the age of 18 who used antimicrobials for at least 72 hours were includ-ed. pDDIs between other drugs and antimicrobials were checked using the "drug interac-tions" modules of the Lexicomp and Micromedex databases. Data were collected from the hospital's records by a clinical pharmacist.Results: A total of 393 drug profiles were evaluated for 100 patients, of which 84.2% were antibacterial drugs. According to at least one database, 88% of patients had pDDIs. Of these, 62.4% were classified as major according to at least one database. Only 27.3% of pDDIs had the same level of interaction in both databases. Common pDDIs posed risks such as additive nephrotoxicity, excessive sedation, respiratory depression and QT interval prolongation.Conclusion: pDDIs should be checked not only by one database but by multiple databases, coupled with the input of an experienced clinical pharmacist.
