By 2009, it had become the most popular metformin combination.In 2005, the stock of Avandamet was removed from the market, after inspections showed the factory where it was produced was violating good manufacturing practices. The medication pair continued to be prescribed separately, and Avandamet was again available by the end of that year. A generic formulation of metformin/rosiglitazone from Teva received tentative approval from the FDA and reached the market in early 2012.However, following a meta-analysis in 2007 that linked the medications use to an increased risk of heart attack,  concerns were raised over the safety of medicines containing rosiglitazone. In September 2010, the European Medicines Agency  recommended that the medication be suspended from the European market because the benefits of rosiglitazone no longer outweighed the risks.It was withdrawn from the market in the UK and India in 2010, and in New Zealand and South Africa in 2011. From November 2011 until November 2013 the FDA did not allow rosiglitazone or metformin/rosiglitazone to be sold without a prescription; moreover, makers were required to notify patients of the risks associated with its use, and the drug had to be purchased by mail order through specified pharmacies.In November 2013, the FDA lifted its earlier restrictions on rosiglitazone after reviewing the results of the 2009 RECORD clinical trial (a six-year, open-label randomized control trial), which failed to show elevated risk of heart attack or death associated with the medication.
Polyphagia or hyperphagia is an abnormally strong, incessant sensation of hunger or desire to eat often leading to overeating. In contrast to an increase in appetite following exercise, polyphagia does not subside after eating and often leads to rapid intake of excessive quantities of food. Polyphagia is not a disorder by itself; rather, it is a symptom indicating an underlying medical condition. It is frequently a result of abnormal blood glucose levels (both hyperglycemia and hypoglycemia), and, along with polydipsia and polyuria, it is one of the "3 Ps" commonly associated with uncontrolled diabetes mellitus. Etymology and pronunciation
The word polyphagia () uses combining forms of poly- + -phagia, from the Greek words πολύς (polys), "very much" or "many", and φαγῶ (phago), "eating" or "devouring". Underlying conditions and possible causes
Polyphagia is one of the most common symptoms of diabetes mellitus. It is associated with hyperthyroidism and endocrine diseases, e.g., Graves disease, and it has also been noted in Prader-Willi syndrome and other genetic conditions caused by chromosomal anomalies. It is only one of several diagnostic criteria for bulimia and is not by itself classified as an eating disorder. As a symptom of Kleine–Levin syndrome, it is sometimes termed megaphagia.Knocking out vagal nerve receptors has been shown to cause hyperphagia.Changes in hormones associated with the female menstrual cycle can lead to extreme hunger right before the period. Spikes in estrogen and progesterone and decreased serotonin can lead to cravings for carbohydrates and fats.
