ABSTRACT
The prevalence rates of obesity, metabolic syndrome, and type 2 diabetes in children are increasing at an alarming rate. The potential impact of these conditions on the individual, the family, and society, especially in regard to the costs and utilization of health care resources, are very serious. Strategies aimed at reducing caloric intake, increasing caloric expenditure through regular exercise, and treating cardiovascular risk factors and type 2 diabetes early and aggressively are necessary to meet the challenges they impose.

This study was designed to compare the pharmacokinetic and short-term pharmacodynamic profile of extended-release glipizide GITS (Glucotrol XL) given in a dosage of 20 mg once daily with that of immediate-release glipizide (Glucotrol) 10mg twice daily in patients with type II diabetes mellitus. In an open-label, randomized, two-way crossover study, each glipizide formulation was administered for 5 days. Serial blood samples were drawn at baseline and on the 5th day of each treatment phase for measurement of glipizide, glucose, insulin, and C-peptide concentrations. At steady state, the mean Cmax after immediate-release glipizide was significantly greater than after glipizide GITS, and the tmax was considerably shorter. Although the mean Cmin with glipizide GITS was about 80% higher than with immediate-release glipizide, the mean AUC0-24 was significantly lower. Despite the lower plasma concentrations with glipizide GITS in this short-term study, the two formulations had similar effects on serum concentrations of glucose, insulin, and C-peptide. The absence of a pronounced peak plasma concentration with the GITS formulation might confer advantages in terms of maintaining clinical effectiveness and reducing the potential to cause adverse effects.
