glipizide, Glipizide XL, Glucotrol: Drug Side Effects

What is glipizide, and how does it work (mechanism of action)?

Glipizide is an oral drug that is used for treating patients with
type 2 diabetes. It belongs to the sulfonylurea class of drugs which also includes glimepiride (Amaryl), glyburide (Diabeta, Glynase), tolbutamide and tolazamide. Insulin is a hormone that is made in the pancreas that when released into the blood causes cells in the body to remove sugar (glucose) from the blood and reduces the formation of glucose by the liver. Patients with type 2 diabetes have high glucose (sugar) levels in their blood because the cells in their bodies are resistant to the glucose-removing effect of the insulin, and the liver produces too much glucose. In addition, in type 2 diabetes the pancreas is unable to produce the increased amounts of insulin that are necessary to overcome the resistance. Glipizide reduces blood glucose by stimulating the pancreas to produce more insulin.

Glipizide is not a cure for diabetes.

The FDA approved glipizide in May 1984.

What is the dosage for glipizide?

• The usual starting dose when using immediate release tablets is 5 mg daily administered 30 minutes before a meal.
• The maximum dose is 40 mg daily.
• Doses higher than 15 mg per day should be divided and given in divided doses daily.
• The starting dose when using extended-release tablets is 5 mg daily up to a maximum dose of 20 mg daily.
• Patients using immediate release tablets may be converted to the nearest equivalent extended-release dose.

Which drugs or supplements interact with glipizide?

:

• Alcohol may prolong the action of glipizide by delaying the absorption and elimination of glipizide. Patients taking glipizide should keep alcohol consumption to a minimum.
• Cholestyramine (Questran, Questran Light) may reduce both the absorption and effects of glipizide. Glipizide should therefore be administered 1-2 hours before cholestyramine is given.
• Fluconazole (Diflucan) also can increase the absorption and effects of glipizide.
• Many drugs can potentially increase or decrease glucose levels thus increasing or decreasing the effects of glipizide. Drug interactions
  that cause low blood glucose (hypoglycemia) can occur with:
  • nonsteroidal anti-inflammatory drugs
    (for example [ibuprofen]),
  • sulfa drugs,
  • warfarin (Coumadin),
  • miconazole (Oravig),
  • fluconazole (Diflucan),
  • voriconazole (Vfend),
  • beta-blockers (for example,
    propranolol [Inderal, Inderal LA, Innopran XL]),
  • androgens (for example fluoxymesterone [Androxy]),
  • chloramphenicol,
  • cimetidine (Tagamet HB),
  • ranitidine (Zantac),
  • clarithromycin (Biaxin),
  • MAO Inhibitors
    (for example, isocarboxazid [Marplan] and phenelzine [Nardil]),
  • mifepristone (Mifeprex),
  • probenecid,
  • quinolone antibiotics, and
  • selective
    serotonin reuptake inhibitors (for example
    paroxetine
    [Paxil],
    fluoxetine
    [Prozac], and
    sertraline
    [Zoloft].
• Drug interactions involving glipizide which can result in high blood glucose (hyperglycemia) can occur with:
  • thiazide diuretics (for example,
    hydrochlorothiazide
    [Microzide]),
  • loop diuretics (for example,
    furosemide
    [Lasix]),
  • corticosteroids such as
    prednisone and
    methylprednisolone (Medrol),
  • phenytoin (Dilantin),
  • colesevelam (Welchol),
  • danazol and somatropin (Genotropin).
• Rifampin may reduce the blood levels of glipizide and this may result in higher levels of sugar in the blood.

Insulin is preferred. In the event that glipizide is used during pregnancy, the manufacturer recommends that it be stopped at least 1 month before the expected date of delivery.

According to reports, glipizide is not found in breast milk. However, the risk of developing hypoglycemia in the nursing infant should be weighed against the potential benefit to the monther of taking glipizide and a decision should be made to discontinue the drug or to discontinue
breastfeeding.
