Prokinetic medications are used in premature infants to promote motility and decrease time to full enteral feeding. Erythromycin and metoclopramide are the most commonly used prokinetic medications in the neonatal intensive care unit (NICU), but their safety profile is not well defined.

Obesity affects nearly one-sixth of US children and results in alterations to body composition and physiology that can affect drug disposition, possibly leading to therapeutic failure or toxic side effects. The depth of available literature regarding obesity’s effect on drug safety, pharmacokinetics, and dosing in obese children is unknown.

Safety of octreotide in hospitalized infants

Octreotide is used off-label in infants for treatment of chylothorax, congenital hyperinsulinism, and gastrointestinal bleeding. The safety profile of octreotide in hospitalized infants has not been described; we sought to fill this information gap.

Pharmacokinetics, Pharmacodynamics, and Safety of Lisinopril in Pediatric Kidney Transplant Patients: Implications for Starting Dose Selection

Hypertension in pediatric kidney transplant recipients contributes to long-term graft loss, yet treatment options–including angiotensin-converting enzyme inhibitors–are poorly characterized in this vulnerable population. We conducted a multicenter, open-label pharmacokinetic (PK) study of daily oral lisinopril in 22 children (ages 7-17 years) with stable kidney transplant function. Standard noncompartmental PK analyses were performed at steady state.

Treatment of supraventricular tachycardia in infants: Analysis of a large multicenter database

Early Human Development June 2015

Access article on PubMed.

Chu PY, Hill KD, Clark RH, Smith PB, Hornik CP

This study used data from a large clinical database to better understand current practices in Supraventricular tachycardia (SVT) management, safety of commonly used medications, and outcomes of hospitalized infants treated for SVT. Significant variation in SVT treatment and suboptimal outcomes warrant future clinical trials to determine best practices in treating SVT in infants.

Fluconazole population pharmacokinetics and dosing for prevention and treatment of invasive Candidiasis in children supported with extracorporeal membrane oxygenation

Candida infections are a leading cause of infectious disease-related death in children supported by extracorporeal membrane oxygenation (ECMO). The ECMO circuit can alter drug pharmacokinetics (PK); thus, standard fluconazole dosing may result in suboptimal drug exposures. The objective of our study was to determine the PK of fluconazole in children on ECMO. Forty children with 367 PK samples were included in the analysis.

Rifampin use and safety in hospitalized infants

This study aims to examine the use and safety of rifampin in hospitalized infants. Observational study of clinical and laboratory adverse events among infants exposed to rifampin from 348 neonatal intensive care units managed by the Pediatrix Medical Group between 1997 and 2012.

Pharmacokinetics and safety of recently approved drugs used to treat methicillin-resistant Staphylococcus aureus infections in infants, children and adults

Expert Review of Clinical Pharmacology May 2015

Methicillin-resistant Staphylococcus aureus (MRSA) remains a significant cause of morbidity in hospitalized infants. Over the past 15 years, several drugs have been approved for the treatment of S. aureus infections in adults. The use of there majority of these drugs has extended into the treatment of MRSA infections in infants, frequently with minimal safety or dosing information. Here, we review current pharmacokinetic, safety, and efficacy data of these drugs with a specific focus in infants.

Simultaneous determination of trimethoprim and sulfamethoxazole in dried plasma and urine spots

Bioanalysis • May 2015

Trimethoprim-sulfamethoxazole (TMP-SMX) is an antimicrobial drug combination commonly prescribed in children and adults. The study objectives were to validate and apply an HPLC-MS/MS method to quantify TMP-SMX in dried plasma spots (DPS) and dried urine spots (DUS), and perform a comparability analysis with liquid matrices.
