Avandia
Rosiglitazone (trade name Avandia) is an antidiabetic drug in the thiazolidinedione class. It works as an insulin sensitizer, by binding to the PPAR in fat cells and making the cells more responsive to insulin. It is marketed by the pharmaceutical company GlaxoSmithKline (GSK) as a stand-alone drug or for use in combination with metformin or with glimepiride. First released in 1999, annual sales peaked at approximately $2.5-billion in 2006; however, following a meta-analysis in 2007 that linked the drug's use to an increased risk of Myocardial infarction, heart attack, sales plummeted to just $9.5-million in 2012. The drug's patent expired in 2012. It was patented in 1987 and approved for medical use in 1999. Despite rosiglitazone's effectiveness at decreasing blood sugar in type 2 diabetes mellitus, its use decreased dramatically as studies showed apparent associations with increased risks of heart attacks and death. Adverse effects alleged to be caused by rosiglitazone were the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Metformin
Metformin, sold under the brand name Glucophage, among others, is the main first-line medication for the treatment of type 2 diabetes, particularly in people who are overweight. It is also used in the treatment of polycystic ovary syndrome. It is not associated with weight gain and is taken by mouth. It is sometimes used as an off-label adjunct to lessen the risk of metabolic syndrome in people who take antipsychotics. Metformin is generally well tolerated. Common adverse effects include diarrhea, nausea, and abdominal pain. It has a small risk of causing low blood sugar. High blood lactic acid level is a concern if the medication is used in overly large doses or prescribed in people with severe kidney problems. It is not recommended in those with significant liver disease. Metformin is a biguanide antihyperglycemic agent. It works by decreasing glucose production in the liver, increasing the insulin sensitivity of body tissues, and increasing GDF15 secretion, which redu ...

Thiazolidinedione
The thiazolidinediones , abbreviated as TZD, also known as glitazones after the prototypical drug ciglitazone, are a class of heterocyclic compounds consisting of a five-membered C3NS ring. The term usually refers to a family of drugs used in the treatment of diabetes mellitus type 2 that were introduced in the late 1990s. Mechanism of action Thiazolidinediones or TZDs act by activating PPARs (peroxisome proliferator-activated receptors), a group of nuclear receptors In the field of molecular biology, nuclear receptors are a class of proteins responsible for sensing steroids, thyroid hormones, vitamins, and certain other molecules. These receptors work with other proteins to regulate the expression of specif ..., specific for ''PPARγ'' (PPAR-gamma, PPARG). They are thus the PPARG agonists subset of PPAR agonists. The endogenous ligands for these receptors are free fatty acids (FFAs) and eicosanoids. When activated, the receptor binds to DNA in complex with the retinoid X ...

Boxed Warning
In the United States, a boxed warning (sometimes "black box warning", colloquially) is a type of warning that appears on the package insert for certain prescription drugs, so called because the U.S. Food and Drug Administration specifies that it is formatted with a 'box' or border around the text. The FDA can require a pharmaceutical company to place a boxed warning on the labeling of a prescription drug, or in literature describing it. It is the strongest warning that the FDA requires, and signifies that medical studies indicate that the drug carries a significant risk of serious or even life-threatening adverse effects. Economists and physicians have thoroughly studied the effects of FDA boxed warnings on prescription patterns. It is not necessarily true that a physician and patient will have a conversation about a drug's boxed warning after it is issued. For instance, an FDA-mandated boxed warning decreased rosiglitazone use by 70%, but that still meant 3.8 million people we ...

Antidiabetic Drug
Drugs used in diabetes treat diabetes mellitus by altering the glucose level in the blood. With the exceptions of insulin, most GLP receptor agonists ( liraglutide, exenatide, and others), and pramlintide, all are administered orally and are thus also called oral hypoglycemic agents or oral antihyperglycemic agents. There are different classes of anti-diabetic drugs, and their selection depends on the nature of the diabetes, age and situation of the person, as well as other factors. Diabetes mellitus type 1 is a disease caused by the lack of insulin. Insulin must be used in type 1, which must be injected. Diabetes mellitus type 2 is a disease of insulin resistance by cells. Type 2 diabetes mellitus is the most common type of diabetes. Treatments include agents that (1) increase the amount of insulin secreted by the pancreas, (2) increase the sensitivity of target organs to insulin, (3) decrease the rate at which glucose is absorbed from the gastrointestinal tract, and (4) i ...

David Graham (epidemiologist)
David J. Graham is an American epidemiologist who is the Associate Director of the Food and Drug Administration's Office of Drug Safety. Graham has spent his career at the FDA studying the safety of drugs, many of them after approval using data from medical insurance companies. He claims successes in removing from the U.S. market the unsafe drugs Omniflox an antibiotic, Rezulin, a diabetes treatment, Fen-Phen and Redux, weight-loss drugs, and phenylpropanolamine, an over-the-counter decongestant, and in restricting the use of Trovan, an antibiotic, to use in hospitals. He also had a part in the removal of Lotronex, Baycol, Seldane, and Propulsid. On November 18, 2004, Dr. Graham testified before the U.S. Senate Committee on Finance about Merck's withdrawal of the popular anti-inflammatory drug Vioxx the previous month because of serious safety concerns. In his testimony, he asserted his personal belief that the policies within the U.S. Food and Drug Administration were ins ...

Beecham Group
The Beecham Group plc was a British pharmaceutical company. It was once a constituent of the FTSE 100 Index. Beecham, after having merged with American pharmaceutical company SmithKline Beckman to become SmithKline Beecham, merged with Glaxo Wellcome to become GlaxoSmithKline (GSK). GSK still uses the Beechams brand name in the UK for its over-the-counter cold and flu relief products. Early history Beecham began as the family business of Thomas Beecham (1820–1907), a chemist. (Beecham would become the grandfather of music conductor Thomas Beecham, 1879–1961). As a boy, Beecham worked as a shepherd, selling herbal remedies as a sideline. He later became a travelling salesman or peddler full time. His first product was Beecham's Pills, a laxative, in 1842. Subsequent success enabled him to open a shop in Wigan in 1847. Beecham opened its first factory in 1849 in St Helens, Lancashire, for the rapid production of medicines. Under his son, Sir Joseph Beecham, 1st Baronet (184 ...

Racemic Mixture
In chemistry, a racemic mixture, or racemate (), is one that has equal amounts of left- and right-handed enantiomers of a chiral molecule or salt. Racemic mixtures are rare in nature, but many compounds are produced industrially as racemates. History The first known racemic mixture was racemic acid, which Louis Pasteur found to be a mixture of the two enantiomeric isomers of tartaric acid. He manually separated the crystals of a mixture by hand, starting from an aqueous solution of the sodium ammonium salt of racemate tartaric acid. Pasteur benefited from the fact that ammonium tartrate salt that gives enantiomeric crystals with distinct crystal forms (at 77 °F). Reasoning from the macroscopic scale down to the molecular, he reckoned that the molecules had to have non-superimposable mirror images. A sample with only a single enantiomer is an ''enantiomerically pure'' or ''enantiopure'' compound. Etymology From racemic acid found in grapes; from Latin ''racemus'', meani ...

Number Needed To Harm
In medicine, the number needed to harm (NNH) is an epidemiological measure that indicates how many persons on average need to be exposed to a risk factor over a specific period to cause harm in an average of one person who would not otherwise have been harmed. It is defined as the inverse of the absolute risk increase, and computed as 1/(I_e - I_u), where I_e is the incidence in the treated (exposed) group, and I_u is the incidence in the control (unexposed) group. Intuitively, the lower the number needed to harm, the worse the risk factor, with 1 meaning that every exposed person is harmed. NNH is similar to number needed to treat (NNT), where NNT usually refers to a positive therapeutic result and NNH to a detrimental effect or risk factor. A combined measure, the number needed to treat for an additional beneficial or harmful outcome (NNTB/H), is also used. Relevance The NNH is an important measure in evidence-based medicine and helps physicians decide whether it is prudent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
