Abstract
Background: The emergence of antibiotic-resistant bacteria poses a significant global concern. The improper use of antibiotics, identified as a leading contributor to this problem, is a widespread issue in medical centers worldwide. Objectives: This study aimed to investigate the utilization pattern of levofloxacin, a commonly prescribed antibiotic. Methods: We conducted a retrospective descriptive study in Ahvaz, Iran, focusing on patients who had received levofloxacin over a 6-month period. Data collection involved a questionnaire comprising patient demographic details, diagnosis information, details concerning levofloxacin administration, and outcomes, all extracted from the patients' medical records. During the assessment, we considered factors such as the correct dosage, frequency of administration, potential drug interactions, and adverse effects. Data analysis was performed using SPSS v. 20. Results: A total of 35 patients, with a mean age of 55.17 ± 20.36 years, received levofloxacin during the study period, and 48.6% of them were women. On average, each patient received 3.20 ± 2.85 grams of levofloxacin, with a minimum dose of 0.500 grams and a maximum of 11.50 grams. The average treatment duration was 3.813 ± 4.26 days. In only 8.6% of cases, the prescribed dosage was deemed inappropriate, while in 40% of cases, the duration of antibiotic use was found to be inadequate. Conclusions: The utilization of levofloxacin was deemed irrational in 40% of cases. Although the prescribed dosage for the respective diagnoses was generally accurate, the treatment duration was often incorrect, potentially contributing to antibiotic resistance.
