Aim This study aimed to evaluate the dosing regimen and therapeutic drug monitoring of vancomycin in this patient population. Method The study included 100 pediatric patients (3 months to 15 years) with various gram-positive bacterial infections. All patients received the initial vancomycin dose of 15 mg/kg every 6 hours. The researchers evaluated the incidence of achieving desired trough levels with this dosing regimen. Results The results revealed that patients between 1.0 and 5.9 years of age were less likely to achieve the desired trough levels with the initial vancomycin dose. Consequently, dose adjustments were made for patients with sub-therapeutic trough levels. These adjustments involved a 25% increase in the vancomycin dose. Importantly, the study found that the higher vancomycin dosing did not have any harmful effects on kidney function in pediatric patients, and no significant adverse effects were observed. Conclusion The dosing regimen of 15 mg/kg every 6 hours was unlikely to achieve the desired trough concentrations in pediatric patients with complicated infections and oncological diseases. The study recommends dose adjustments for the treatment of different infections in this population to increase the likelihood of reaching therapeutic steady-state concentrations of vancomycin.
