GLIPIZIDE XL- GLIPIZIDE TABLET, EXTENDED RELEASE ST MARYS MEDICAL PARK PHARMACY ---------- GLIPIZIDE XL (GLIPIZIDE) EXTENDED-RELEASE TABLETS _FOR ORAL USE_ DESCRIPTION Glipizide is an oral blood-glucose-lowering drug of the sulfonylurea class. The Chemical Abstracts name of glipizide is 1-cyclohexyl-3-[[p-[2-(5- methylpyrazinecarboxamido)ethyl] phenyl]sulfonyl]urea. The molecular formula is C H N O S; the molecular weight is 445.55; the structural formula is shown below: Glipizide is a whitish, odorless powder with a pKa of 5.9. It is insoluble in water and alcohols, but soluble in 0.1 _N_ NaOH; it is freely soluble in dimethylformamide. Glipizide XL is the Greenstone brand name for glipizide GITS. Glipizide GITS (Gastrointestinal Therapeutic System) is formulated as a once-a-day controlled release tablet for oral use and is designed to deliver 2.5, 5, or 10 mg of glipizide. Inert ingredients in the 2.5 mg, 5 mg and 10 mg formulations are: polyethylene oxide, hypromellose, magnesium stearate, sodium chloride, red ferric oxide, cellulose acetate, polyethylene glycol, Opadry blue (OY-LS-20921)(2.5 mg tablets), Opadry white (YS-2-7063)(5 mg and 10 mg tablet) and black ink (S-1-8106). SYSTEM COMPONENTS AND PERFORMANCE Glipizide XL extended-release tablet is similar in appearance to a conventional tablet. It consists, however, of an osmotically active drug core surrounded by a semipermeable membrane. The core itself is divided into two layers: an "active" layer containing the drug, and a "push" layer containing pharmacologically inert (but osmotically active) components. The membrane surrounding the tablet is permeable to water but not to drug or osmotic excipients. As water from the gastrointestinal tract enters the tablet, pressure increases in the osmotic layer and "pushes" against the drug layer, resulting in the release of drug through a small, laser-drilled orifice in the membrane on the drug side of the tablet. 21 27 5 4 ® ® The Glipizide XL extended-release tablet is designed to provide a controlled rate of קרא את המסמך השלם
