Generic name: Glipizide
Brand name: Glucotrol Xl
Glucotrol Xl is an oral antidiabetic drug prescribed to treat type 2 (non-insulin-dependent) diabetes. In diabetics either the body doesn’t make enough insulin or the insulin that is produced no longer works properly. Glucotrol Xl controls diabetes by stimulating the pancreas to secrete more insulin. If you suffer from type 1 diabetes, you will need to use insulin and will not be able to use Glucotrol Xl. Occasionally, type 2 diabetics must take insulin injections on a temporary basis, especially during stressful periods or times of illness. Controlling high blood sugar helps prevent kidney disease, strokes, heart disease, circulation problems, blindness as well as sexual function problems (impotence). Bioavailability is 100% (immediate-release); 90% (extended-release). Tmax is 1 to 3 h (immediate-release); 6 to 12 h (extended-release). Food delays absorption by about 40 min.
Be aware that Glucotrol Xl is not an oral form of insulin, it cannot substitute insulin.
