There is limited information on infant drug exposure via breastfeeding by mothers who are receiving antiepileptic therapy.To provide direct, objective through breast milk.This prospective cohort study was conducted between December 2012 to October 2016, with follow-up in children until 6 years of age at 20 sites across the United States. Data were collected an observational multicenter investigation (Maternal Outcomes and Neurodevelopmental Effects Antiepileptic Drugs [MONEAD]) outcomes...

Abstract Objective To evaluate the pharmacokinetics of a purified oral cannabidiol ( CBD ) capsule administered with and without food in adults refractory epilepsy. Methods Adult patients who were prescribed for seizures, had localization‐related intractable epilepsy ≥4 seizures per month, qualified Minnesota cannabis enrolled. A single dose 99% pure capsules was taken under both fasting (no breakfast) fed (high fat 840‐860 calorie) conditions. Blood sampling plasma concentrations performed...

Objective To determine how early lamotrigine clearance (LTG‐CL/F) increases during pregnancy in women with epilepsy and to quantify the relationship of LTG‐CL/F estradiol concentrations gestational week. Methods This was a multicenter, observational study pregnant on no interacting concomitant medications, employing frequent blood sampling prior pregnancy. A population mixed‐effects modeling approach used describe between week estradiol. Akaike information criterion (AIC) compared goodness...

Lamotrigine clearance can change drastically in pregnant women with epilepsy (PWWE) making it difficult to assess the need for dosing adjustments. Our objective was characterize lamotrigine pharmacokinetics PWWE during pregnancy and postpartum along a control group of nonpregnant (NPWWE). The Maternal Outcomes Neurodevelopmental Effects Antiepileptic Drugs (MONEAD) study prospective, observational, 20 site, cohort conducted United States (December 2012 February 2016).

Objectives: Several biotherapeutics modulating targets related to Th2 immunity have been investigated for the treatment of atopic dermatitis (AD) [1-3]. More recently, there has interest in exploring novel multi-pathway combination therapies with potential improved efficacy either through additive or synergistic combinations and alarmin pathways. A quantitative systems pharmacology-based approach incorporating disparate preclinical clinical information from monotherapies can be used...

Pharmacokinetic studies are vital in development and optimization of drugs. While blood samples can be collected either EDTA, heparin or citrate containing tubes for the estimation drug levels plasma, EDTA more commonly used. The purpose this study was to evaluate effects anticoagulants on bioanalysis Six drugs used extensively cancer therapy were selected. Albino wistar rats (N = 6 per drug) dosed with one following intraperitoneally-pemetrexed (50 mg/kg), imatinib erlotinib (25 meropenem...

Ritlecitinib is a small molecule in clinical development that covalently and irreversibly inhibits Janus kinase 3 (JAK3) the TEC family of kinases (BTK, BMX, ITK, TXK, TEC). This phase 1, open-label, parallel-group study assessed target occupancy functional effects ritlecitinib on JAK3 healthy participants aged 18-60 years who received 50 or 200 mg single doses day 1. Blood samples to assess pharmacokinetics, occupancy, pharmacodynamics were collected over 48 hours. Target was using mass...

Job's syndrome or hyper-immunoglobulin E (HIES) is a heterogeneous complex of immunodeficiencies distinguishes by skin abscesses, recurrent pneumatoceles staphylococcal infections, high serum immunoglobulin levels and eczematous dermatitis. It has two types depends on type gene involved; autosomal-dominant HIES (AD-HIES), which develops due to signal transducer activator transcription 3 autosomal recessive caused DOCK8 mutation.

ABSTRACT Background Paclitaxel is dosed according to body surface area (BSA) but there scant information on actual drug exposure in overweight and obese patients. Methods Early breast cancer patients receiving paclitaxel at 175 mg/m 2 every 3 weeks, two BMI groups (normal, 18–24.9 kg/m overweight/obese, ≥25 , respectively), matched for age, serum albumin bilirubin levels using minimization technique, were included. Sparse pharmacokinetic (PK) sampling was performed 7 time points from 0 h...

Abstract Introduction: Connective Tissue Disease Related Interstitial Lung (CTD-ILD) is often treated with immunosuppressant medications; common among these Mycophenolate Mofetil (MMF). We hypothesized that co-treatment corticosteroids would impact disease progression. Methods: examined a consecutive cohort of CTD-ILD patients followed at Temple University Hospital in Philadelphia, PA since 2015 who had pulmonary function tests (PFTs) performed by American Thoracic Society (ATS)/European...
