Study Evaluating Pantoprazole Sodium Enteric-Coated Spheroid Suspension In Infants With Presumed GERD

Study Evaluating Pantoprazole Sodium Enteric-Coated Spheroid Suspension In Infants With Presumed GERD

A Multicenter, Randomized, Open Label, Single and Multiple Dose Study of the Pharmacokinetics and Pharmacodynamics of 2 Dose Levels of Pantoprazole Sodium Enteric-Coated Spheroid Suspension in Infants Aged 1 Through 11 Months With Presumed GERD

The purpose of this study is to characterize the pharmacokinetic (PK) and pharmacodynamic (PD) profiles to determine the safety and tolerability of single and multiple doses of pantoprazole in infants aged 1 through 11 months.

Pharmacokinetic (PK) parameters, including peak plasma concentration, were determined following a single oral dose of pantoprazole

Pharmacokinetic (PK) parameters, including time to peak plasma concentration, were determined following a single oral dose of pantoprazole.

Pharmacokinetic (PK) parameters, including the terminal-phase disposition half-life, were determined following a single oral dose of pantoprazole. Half-life is the time required for half the quantity of absorbed drug to be metabolized or eliminated by normal biological processes.

Pharmacokinetic (PK) parameters, including AUC, were determined following a single oral dose of pantoprazole. AUC is a measure of the plasma concentration of the drug over time. It is used to characterize drug absorption.

Pharmacokinetic (PK) parameters, including apparent oral clearance, were determined following a single oral dose of pantoprazole. Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Clearance obtained after oral dose (apparent oral clearance) is influenced by the fraction of the dose absorbed.

Plasma concentration of pantoprazole after multiple doses was measured to see if there was any accumulation of the drug.

Intragastric pH is a method for evaluating gastric acidity scaled 0-9. A lower pH means more acidity. A longer duration of esophageal mucosa exposure to a gastric refluxate with a pH <4.0 correlates with more severe mucosal injury in patients with gastroesophageal reflux disease (GERD).

Normalized Area of Gastric Hydrogen Ion Activity Over Time is a measure of the area under the curve of the gastric hydrogen ion activity over time, which is normalized for a 24-hour period.
