WARNING
  • Thiazolidinediones, including Pioglitazone, cause or exacerbate congestive heart failure in some patients.
  • After initiation of Pioglitazone, and after dose increases, monitor patients carefully for signs and symptoms of heart failure (e.g., excessive, rapid weight gain, dyspnea, and/or edema). If heart failure develops, it should be managed according to current standards of care and discontinuation or dose reduction of Pioglitazone must be considered.
  • Pioglitazone is not recommended in patients with symptomatic heart failure.
  • Initiation of Pioglitazone in patients with established New York Heart Association (NYHA) Class III or IV heart failure is contraindicated ecessary to aid in prevention of lactic acidosis, particularly in the elderly.
Indication(s)

Monotherapy and Combination Therapy

Pioglitazone is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus in multiple clinical settings.

Important Limitations of Use

Pioglitazone exerts its antihyperglycemic effect only in the presence of endogenous insulin. Pioglitazone should not be used to treat type 1 diabetes or diabetic ketoacidosis, as it would not be effective in these settings. Use caution in patients with liver disease.

Dosage & Administration

Recommendations for All Patients

Pioglitazone should be taken once daily and can be taken without regard to meals.

The recommended starting dose for patients without congestive heart failure is 15 mg or 30 mg once daily.

The recommended starting dose for patients with congestive heart failure (NYHA Class I or II) is 15 mg once daily.

The dose can be titrated in increments of 15 mg up to a maximum of 45 mg once daily based on glycemic response as determined by HbA1c.

After initiation of Pioglitazone or with dose increase, monitor patients carefully for adverse reactions related to fluid retention such as weight gain, edema, and signs and symptoms of congestive heart failure.

Liver tests (serum alanine and aspartate aminotransferases, alkaline phosphatase, and total bilirubin) should be obtained prior to initiating Pioglitazone. Routine periodic monitoring of liver tests during treatment with Pioglitazone is not recommended in patients without liver disease. Patients who have liver test abnormalities prior to initiation of Pioglitazone or who are found to have abnormal liver tests while taking Pioglitazone should be managed as described under Warnings and Precautions.

Concomitant Use with an Insulin Secretagogue or Insulin

If hypoglycemia occurs in a patient co-administered Pioglitazone and an insulin secretagogue (e.g., sulfonylurea), the dose of the insulin secretagogue should be reduced.

If hypoglycemia occurs in a patient co-administered Pioglitazone and insulin, the dose of insulin should be decreased by 10% to 25%. Further adjustments to the insulin dose should be individualized based on glycemic response.

Concomitant Use with Strong CYP2C8 Inhibitors

Coadministration of Pioglitazone and gemfibrozil, a strong CYP2C8 inhibitor, increases pioglitazone exposure approximately 3-fold. Therefore, the maximum recommended dose of Pioglitazone is 15 mg daily when used in combination with gemfibrozil or other strong CYP2C8 inhibitors.
Contraindications Hypersensitivity. Type 1 diabetes mellitus, symptomatic or history of heart failure, diabetic ketoacidosis, childn <18 yr. Lactation.
Special Precautions Increased risk of hypoglycaemia when used with insulin or oral hypoglycaemics. Oedema, congestive heart failure, hepatic dysfunction, jaundice, anaemia. May cause ovulation in premenopausal, anovulatory women. Monitor liver function before and during treatment. Monitor glycaemic control. Pregnancy. Caution when oral contraceptives or hormonal replacement therapy is used in diabetics due to increased risk of arterial diseases. Stop treatment if ALT increases and remains >3 times above the upper limit of normal or if jaundice develops.
Adverse Drug Reaction(s) Pharyngitis, oedema, headache, upper resp tract infection, sinusitis, anaemia; GI disturbances, wt gain, visual disturbances, dizziness, arthralgia, haematuria, impotence.
Drug Interactions Ketoconazole and gemfibrozil may increase the plasma concentrations of pioglitazone while enzyme inducers such as rifampicin may decrease the plasma concentrations. Increased risk of fluid retention when used with NSAIDs.
Lab Interference Transient elevations in creatine phosphokinase levels were observed.
Pregnancy Category (FDA) Category C: Either studies in animals have revealed adverse effects on the foetus (teratogenic or embryocidal or other) and there are no controlled studies in women or studies in women and animals are not available. Drugs should be given only if the potential benefit justifies the potential risk to the foetus.
Storage Store at 25°C.
Pharmacology Pioglitazone is as a potent and highly selective agonist for the peroxisome proliferator activated receptor-gamma (PPAR). Activation of these receptors promotes the production of gene products involved in lipid and glucose metabolism. It also improves insulin response to target cells witho increasing the pancreatic secretion of insulin.
Onset: Delayed.
Absorption: Peak plasma concentrations after 2 hr.
Distribution: Protein-binding: >99%.
Metabolism: Extensively metabolised by hydroxylation and oxidation.
Excretion: Urine (15-30%); faeces (as metabolites); 3-7 hr (elimination half-life, parent drug).
ATC Classification A10BG03 - pioglitazone; Belongs to the class of thiazolidinediones. Used in the treatment of diabetes.

IMPORTANT WARNING:

Pioglitazone and other similar medications for diabetes may cause or worsen congestive heart failure (condition in which the heart is unable to pump enough blood to the other parts of the body). Before you start to take pioglitazone, inform your doctor if you have or have ever had congestive heart failure, especially if your heart failure is so severe that you must limit your activity and are only comfortable when you are at rest or you must remain in a chair or bed. Also inform your doctor if you were born with a heart defect, and if you have or have ever had swelling of the arms, hands, feet, ankles, or lower legs; heart disease; high cholesterol or fats in the blood; high blood pressure; coronary artery disease (narrowing of the blood vessels that supply blood to the heart); a heart attack; an irregular heartbeat; or sleep apnea. Your doctor may inform you not to take pioglitazone or may monitor you carefully during your treatment.

If you develop congestive heart failure, you may experience certain symptoms. inform your doctor immediately if you have any of the following symptoms, especially when you first start taking pioglitazone or after your dose is increased: large weight gain in a short period of time; shortness of breath; swelling of the arms, hands, feet, ankles, or lower legs; swelling or pain in the stomach; waking up short of breath during the night; needing to sleep with extra pillows under your head in order to breathe easier while lying down; frequent dry cough or wheezing; difficulty thinking clearly or confusion; fast or racing heart beat; not able to walk or exercise as well; or increased tiredness.

Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with pioglitazone and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http:www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer's website to obtain the Medication Guide.

Talk to your doctor about the risks of taking pioglitazone.

 

Why is Pioglitazone prescribed?

Pioglitazone is used with a diet and exercise program and sometimes with other medications, to treat type 2 diabetes (condition in which the body does not use insulin normally and therefore cannot control the amount of sugar in the blood). Pioglitazone is in a class of medications called thiazolidinediones. It works by increasing the body's sensitivity to insulin, a natural substance that helps control blood sugar levels. Pioglitazone is not used to treat type 1 diabetes (condition in which the body does not produce insulin and, therefore, cannot control the amount of sugar in the blood) or diabetic ketoacidosis (a serious condition that may develop if high blood sugar is not treated).

How should Pioglitazone be used?

Pioglitazone comes as a tablet to take by mouth. It is usually taken once daily with or without meals. Take pioglitazone at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take pioglitazone exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Your doctor may start you on a low dose of pioglitazone and gradually increase your dose.

Pioglitazone controls type 2 diabetes but does not cure it. It may take 2 weeks for your blood sugar to decrease and 2 to 3 months for you to feel the full effect of pioglitazone. Continue to take pioglitazone even if you feel well. Do not stop taking pioglitazone without talking to your doctor.

Other uses for Pioglitazone

Pioglitazone may be prescribed for other uses; ask your doctor or pharmacist for more information.
