Avandamet (Rosiglitazone Maleate) - Summary



Rosiglitazone maleate: CONGESTIVE HEART FAILURE

  • Thiazolidinediones, including rosiglitazone, cause or exacerbate congestive heart failure in some patients [see Warnings and Precautions]. After initiation of AVANDAMET®, and after dose increases, observe patients carefully for signs and symptoms of heart failure (including excessive, rapid weight gain, dyspnea, and/or edema). If these signs and symptoms develop, the heart failure should be managed according to current standards of care. Furthermore, discontinuation or dose reduction of AVANDAMET must be considered.
  • AVANDAMET is not recommended in patients with symptomatic heart failure. Initiation of AVANDAMET in patients with established NYHA Class III or IV heart failure is contraindicated. [See Contraindications (4), Warnings and Precautions .]

Metformin hydrochloride: LACTIC ACIDOSIS

  • Lactic acidosis is a rare, but serious complication that can occur due to metformin accumulation. The risk increases with conditions such as sepsis, dehydration, excess alcohol intake, hepatic insufficiency, renal impairment, and acute congestive heart failure. [See Warnings and Precautions .]
  • Symptoms include malaise, myalgias, respiratory distress, increasing somnolence, and nonspecific abdominal distress. Laboratory abnormalities include low pH, increased anion gap and elevated blood lactate. [See Warnings and Precautions .]
  • If acidosis is suspected, discontinue AVANDAMET and hospitalize the patient immediately [see Warnings and Precautions].


AVANDAMET contains 2 oral antidiabetic drugs: rosiglitazone maleate and metformin hydrochloride. Rosiglitazone maleate is an oral antidiabetic agent, which acts primarily by increasing insulin sensitivity. Rosiglitazone improves glycemic control while reducing circulating insulin levels.

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

Important Limitations of Use:

  • •Due to its mechanism of action, rosiglitazone is active only in the presence of endogenous insulin. Therefore, AVANDAMET should not be used in patients with type 1 diabetes.
  • •Coadministration of AVANDAMET with insulin is not recommended [see Warnings and Precautions (5.2, 5.3)].

Published Studies Related to Avandamet (Rosiglitazone)

Rosiglitazone decreases plasma levels of osteoprotegerin in a randomized clinical trial with type 2 diabetes patients. [2011.12]
Cardiovascular disease is the leading cause of death in patients with type 2 diabetes mellitus (T2DM). We suggested that plasma osteoprotegerin (OPG), a strong, independent predictor of cardiovascular disease, could discriminate between anti-diabetic treatments depending on their benefits regarding cardiovascular disease...

Rosiglitazone decreases fasting plasma peptide YY(3-36) in type 2 diabetic women: a possible role in weight gain? [2011.11.19]
Rosiglitazone often results in weight gain. We hypothesized that rosiglitazone may modulate circulating levels of ghrelin and peptide YY(3-36) and this modulation may be related to weight-gaining effect of this agent... Rosiglitazone-induced decrease in fasting peptide YY(3-36) levels may in part contribute to orexigenic and weight-gaining effect of this thiazolidinedione derivative.

Rosiglitazone and pioglitazone for the treatment of Alzheimer's disease. [2011.11]
CONCLUSIONS: Results from clinical trials and current safety data suggest that rosiglitazone should not be used for the treatment of AD. Application of results from trials evaluating pioglitazone in the treatment of AD is limited because of major trial limitations; therefore, it should not be recommended at this time. Although these drugs are not commonly used in the treatment of AD, further pharmacoepidemiologic studies are warranted before their use can be recommended.

Effect of lifestyle intervention plus rosiglitazone or placebo therapy on left ventricular mass assessed with cardiovascular magnetic resonance in the metabolic syndrome. [2011.10.28]
ABSTRACT: BACKGROUND: To evaluate the effect of lifestyle intervention in conjunction with rosiglitazone or placebo therapy on left ventricular (LV) mass, using cardiovascular magnetic resonance (CMR) in the metabolic syndrome... CONCLUSIONS: Lifestyle intervention resulted in a reduction of LV mass-I in the metabolic syndrome, indicating reverse remodeling. However, rosiglitazone therapy may have inhibited this positive reverse remodeling. TRIAL REGISTRATION: Current Controlled Trials ISRCTN54951661.

A randomized controlled trial of the effect of rosiglitazone and clomiphene citrate versus clomiphene citrate alone in overweight/obese women with polycystic ovary syndrome. [2011.10.04]
Background: In women suffering from polycystic ovary syndrome, correction of hyperinsulinemia results in enhanced responsiveness to ovulation induction agents. The effect of rosiglitazone was investigated on ovulation induction in obese women with PCOS... Conclusions: Short term administration of rosiglitazone to overweight and obese PCOS women results in enhancement of CC induced ovulation as well as improvement of insulin sensitivity.

Clinical Trials Related to Avandamet (Rosiglitazone)

AVANDAMET Versus Metformin And Sulphonylurea In People With Poorly Controlled Type 2 Diabetes [Completed]
This study compares the effects of Avandamet (rosiglitazone maleate/metformin) treatment and metformin plus sulphonylurea treatment in overweight people with type 2 diabetes.

AVANDAMET Versus Metformin For Type 2 Diabetes Mellitus [Completed]
This 48-week study will compare AVANDAMET vs. Metformin monotherapy for blood glucose control in patients with Type 2 Diabetes Mellitus.

Study Of AVANDAMET With Or Without Insulin In Type II Diabetes Mellitus Patients [Completed]
This study was designed to test the safety and efficacy (how well it works) of AVANDAMET in combination with insulin in improving the control of blood sugar when compared with taking insulin on its own. AVANDAMET capsules contain a fixed dose of AVANDIA and metformin. Both AVANDIA and metformin are medicines which are individually licensed for the treatment of type II diabetes mellitus. Because they act in different ways, it is thought that combining them may give an increased benefit of treating diabetes and reducing blood sugar.

Avandia™ + Amaryl™ or Avandamet™ Compared With Metformin (AVALANCHE™ Study) [Completed]
The incidence of type 2 diabetes is on the increase. According to recent Canadian Diabetes Association guidelines glucose control, based on the A1C measurement, needs to be achieved within a 6-12 month period of time after the initial diagnosis of type 2 diabetes. The guidelines on the use of antihyperglycemic agents identify the potential benefits of sub-maximal oral combination therapy in order to achieve more rapid and improved glycemic control compared with higher dose monotherapy. Furthermore, many patients on prolonged oral antihyperglycemic monotherapy who then start on combination therapy may not achieve the required target glycemic control. Indeed early initiation of combination therapies may be necessary to achieve and maintain glycemic targets because of the progressive deterioration of pancreatic β cell function and glycemic control.

Rosiglitazone and Metformin: Outcomes Trial in Nondiabetic Patients With Stable Coronary Syndromes (Romance) Pilot Study [Recruiting]
Nearly half of all Americans will die from cardiovascular disease caused by the build up of atherosclerotic plaque within coronary arteries. Most deaths in these patients arise from the development of acute coronary syndromes (ACS) such as myocardial infarction, unstable angina, or sudden death. ACS is characterized by coronary plaque erosion or rupture, which is triggered by endothelial changes, including inflammation, and thrombosis. Diabetes, with insulin resistance as a major component, has been shown to engender adverse metabolic events within the endothelial cell [1], including impaired endothelial function, augmented vasoconstriction, increased inflammation and thrombosis. Activation of the transcription factors nuclear factor KB (NF-KB) and activator protein 1 (AP-1) induces inflammatory gene expression, with liberation of leukocyte-attracting chemokines, increased production of inflammatory cytokines, and augmented expression of cellular adhesion molecules. These metabolic processes may therefore play a significant role in the development of ACS. The hypothesis is that rosiglitazone and metformin, or the combination of both may provide positive anti-atherogenic effect, even among patients without diabetes. This pilot study proposes to evaluate the effect of placebo vs. combined rosiglitazone/metformin (Avandamet®) on surrogate blood markers of atherosclerosis activity among non-diabetic and pre-diabetic patients with known stable coronary syndromes. This will provide further evidence justifying a large definitive outcomes-based clinical trial.
