Abstract

Introduction: The rational use of drugs is one of the main elements of achieving the best pharmacotherapy method for patients. Linezolid is used for infections caused by gram-positive bacteria, including vancomycin-resistant staphylococci and vancomycin-resistant enterococci, but the inappropriate use of this drug has led to the emergence of linezolid-resistant strains. The purpose of this study was to investigate the manner of Linezolid prescription in Shahid Chamran Hospital of Isfahan City in 2021.

Methods: This cross sectional study was conducted during a period of 6 months (From September 1, 2021 to February 31, 2022) on 102 patients admitted to Shahid Chamran Hospital in Isfahan City. Patient information such as demographic information, indication and dosages of drugs, the basis of drug prescription, side effects and drug interactions, etc. were extracted from the medical records of patients and hospital systems and recorded in designed forms. After matching the information with the relevant guidelines, statistical analysis was performed using SPSS-16 software.

Results: Out of the 102 patients, who received linezolid, 75.1% were men and the rest were women. 99% of the cases were prescribed experimentally and 1% was based on culture. In 40.2% of the patients, drugs were prescribed irrationally in terms of prescription indications. In 84.3% of the cases, a change in treatment regimen was observed after receiving the culture results.

Conclusion: A large percentage of cases of linezolid drug prescription was not done correctly. Furthermore, it has not been attention to the side effects caused by the drug, especially thrombocytopenia.
