Dose Optimization of Antibiotics in Renally Impaired Patients in Indian
Settings: A Prospective Observational Study
Abstract
Rationale: In renal impairment, the pharmacokinetic properties of the
drug are altered, and the systemic clearance is reduced. The current
study aimed to assess the optimization of antibiotics dosing in renally
impaired patients in a healthcare setting. Methodology: A prospective
study was conducted on in-patients in the nephrology department,
prescribed with antibiotics in a tertiary care hospital. The creatinine
clearance was calculated by Cockroft-Gault and Jelliffe method. The dose
appropriateness was cross-checked using standard databases and
literature from the manufacturer data. Results: Of 139 participants 112
(80.6%) had CKD and 27(19.4%) had AKI. Urinary tract infection was
most common. Monotherapy (62) was the most preferred choice, followed by
dual in (43) and triple in (7%). A positive clinical outcome of 79.1%
was achieved. Cefoperazone-sulbactam was most widely used antibiotic.
The mean difference in creatinine clearance was 4.55ml/min in AKI
patients. Conclusion: Dose appropriateness is a significant factor in
achieving favorable clinical outcomes.
