Vancomycin: Predictive Performance of a Population Pharmacokinetic Model and Optimal Dose in Neonates and Young Infants

Clinical Pharmacology in Drug Development
Amélie MarsotN Simon


Model evaluation is an important issue in population pharmacokinetic analyses. The objectives were to evaluate the predictive performance of previously published pediatric population pharmacokinetic models for vancomycin in a new data set and to propose an optimal dose to obtain a vancomycin concentration target. External evaluation was conducted for all the published models of vancomycin in neonates and young infants with a new data set of 70 patients. Bias and accuracy were calculated. Advanced analyses were performed to evaluate the predictive performance of the best model. This population pharmacokinetic analysis was performed to simulate doses of vancomycin according to the appropriate target concentration. All models gave almost the same results, except 2 that were not acceptable. Nevertheless, the model described by Oudin et al presented the best results with a bias and accuracy of 4.0% and 27.8%, respectively. Simulations showed that the maintenance dose should be adjusted more precisely to each neonate based on his or her weight and serum creatinine value. Simulations have allowed the authors to describe new dosage schedules, and a chart was created to help clinicians to adapt dosage of vancomycin. Because of pharmacok...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.


Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
