pantoprazole has been researched along with Body Weight in 6 studies

Pantoprazole: 2-pyridinylmethylsulfinylbenzimidazole proton pump inhibitor that is used in the treatment of GASTROESOPHAGEAL REFLUX and PEPTIC ULCER.
pantoprazole : A member of the class of benzimidazoles that is 1H-benzimidazole substituted by a difluoromethoxy group at position 5 and a [(3,4-dimethoxypyridin-2-yl)methyl]sulfinyl group at position 2.

Body Weight: The mass or quantity of heaviness of an individual. It is expressed by units of pounds or kilograms.

The CYP2C19 Genotype and Its Association With CYP2C19 Phenotype

To examine the association of CYP2C19 genotype and its association with CYP2C19 phenotypes. To characterize the ability of the CYP2C19 genotype to predict pantoprazole plasma clearance, a correlation with CYP2C19 phenotype was explored using both standard linear and nonlinear regression techniques and their respective tests for significance and goodness of fit. In addition, the impact of all covariates on pantoprazole systemic exposure and apparent plasma clearance (e.g., demographic determinants of extent of obesity such as the waist:hip ratio, CYP2C19 genotype, BMI, and REE) was explored using validated population-based PK methods (NONMEM).

Harmonic Mean of Precision and Recall (F1) of the Breath Test to Discriminate the CYP2C19 Extensive Metabolizer (EM) From Intermediate Metabolizer (IM) Phenotype

Children with common CYP2C19 genotypes (*1/*1, *1*17, *1/*2, *2/*17) who had evaluable breath test data (n=59) were included to evaluate the breath test's precision in discriminating the CYP2C19 Extensive Metabolizer (EM; *1/*1, *1*17) from the Intermediate Metabolizer (IM; *1/*2, *2/*17) phenotype in the first 3 hrs after study drug administration. A 3-hour window was chosen for convenience. A predictive model using breath test features (change in ratio of C12-to-C13 in exhaled CO2) was build and validated to predictphenotype for each child. We drew bootstrap samples, each stratified to preserve the observed prevalence of EM/IMs in the original cohort (n=59). Sampling with replacement left out 38% of the original sample to use as a test dataset to validate model performance. For each bootstrap sample, a 500-tree Extremely randomized Extra-Tree Forest was constructed after seeding. Using phenotypes predicted by the forest, predictive accuracy was assessed by computing the F1. (NCT01887743)
