    Metformin chemistry


    Metformin hydrochloride is an insulin-sensitizing agent used to treat type 2 diabetes. It is increasingly being used with other diseases featuring insulin resistance, like polycystic ovary syndrome and non-alcoholic steatohepatitis. Metformin is an oral antidiabetic drug in the biguanide class. It is the first-line drug of choice for the treatment of type 2 diabetes, in particular, in overweight and obese people and those with normal kidney function. Its use in gestational diabetes has been limited by safety concerns. It is also used in the treatment of polycystic ovary syndrome, and has been investigated for other diseases where insulin resistance may be an important factor. Metformin works by suppressing glucose production by the liver. Metformin is the only antidiabetic drug that has been conclusively shown to prevent the cardiovascular complications of diabetes. It helps reduce LDL cholesterol and triglyceride levels, and is not associated with weight gain First synthesized and found to reduce blood sugar in the 1920s, metformin was forgotten for the next two decades as research shifted to insulin and other antidiabetic drugs.

    After eating a meal) plasma glucose and is not chemically or pharmacologically related to any other classes of oral antihyperglycemic agents. Two guanide molecules joined together are known as biguanides, which is a name that was given by Rathke in 1879 when he obtained a new compound after a condensation reaction of thiourea and phosphorus trichloride with guanidine. The synthesis was henceforth improved by using a condensation reaction at 110 ºC of cyanoguanidine with an ammoniac solution of cupric sulfate in a sealed tube. In 1892 it was discovered that biguanides can be obtained via direct fusion of ammonium chloride with cyanoguanidine at 195 ºC for a couple of minutes. This procedure is still employed in the synthesis of substituted bigunaides to detect the presence of biguanide. To achieve ecofriendly synthesis of the target molecule, the starting materials are made to react by adjusting the reaction conditions in such a way that the by-products and wastes are eliminated, with minimal use of organic solvents. Thin layer chromatography has been described as a tool for reaction optimization in microwave assisted synthesis. The UK Prospective Diabetes Study, a large clinical trial performed in 1980-90s, provided evidence that metformin reduced the rate of adverse cardiovascular outcomes in overweight patients with type 2 diabetes relative to other antihyperglycemic agents. Treatment guidelines for major professional associations including the European Association for the Study of Diabetes, the European Society for Cardiology and the American Diabetes Association, now describe evidence for the cardiovascular benefits of metformin as equivocal. In 2017, the American College of Physicians's guidelines were updated to recognize metformin as the first-line treatment for type-2 diabetes. For example, a 2014 review found tentative evidence that people treated with sulfonylureas had a higher risk of severe low blood sugar events (RR 5.64), though their risk of non-fatal cardiovascular events was lower than the risk of those treated with metformin (RR 0.67). There was not enough data available at that time to determine the relative risk of death or of death from heart disease. study known as the Diabetes Prevention Program, participants were divided into groups and given either placebo, metformin, or lifestyle intervention and followed for an average of three years. Metformin treatment of people at a prediabetes stage of risk for type 2 diabetes may decrease their chances of developing the disease, although intensive physical exercise and dieting work significantly better for this purpose. The intensive program of lifestyle modifications included a 16-lesson training on dieting and exercise followed by monthly individualized sessions with the goals of decreasing weight by 7% and engaging in physical activity for at least 150 minutes per week. The incidence of diabetes was 58% lower in the lifestyle group and 31% lower in individuals given metformin. Among younger people with a higher body mass index, lifestyle modification was no more effective than metformin, and for older individuals with a lower body mass index, metformin was no better than placebo in preventing diabetes.

    The infant's medication exposure can be limited by prescribing medications to the breast-feeding mother that are poorly absorbed orally, by avoiding breast-feeding during times of peak maternal serum drug concentration and by prescribing topical therapy when possible. D., Conemaugh Memorial Medical Center, Johnstown, Pennsylvania LUIS S. D., Conemaugh Memorial Medical Center, Johnstown, Pennsylvania DONNA J. The transfer of medications into breast milk depends on a concentration gradient that allows passive diffusion of nonionized, non-protein-bound drugs. A drug that is safe for use during pregnancy may not be safe for the nursing infant. Prescribing medications for a breast-feeding mother requires weighing the benefits of medication use for the mother against the risk of not breast-feeding the infant or the potential risk of exposing the infant to medications. Mothers of premature or otherwise compromised infants may require altered dosing to avoid drug accumulation and toxicity in these infants. The most accurate and up-to-date sources of information, including Internet resources and telephone consultations, should be used. Physicians receive little education about breast-feeding and even less training on the effects of maternal medications on the nursing infant.1 Yet, concern about potential harm to the nursing infant from maternal medications is often cited as a reason to advise discontinuation of breastfeeding.

    Nolvadex (Tamoxifen) belongs to a category and class of drugs known as selective Estrogen receptor modulators (SERMs). Selective Estrogen receptor modulators belong to an even broader class of drugs known as anti-estrogens. The other subcategory of drug under the anti-estrogens category is known as aromatase inhibitors (AIs), such as Aromasin (Exemestane) and Arimidex (Anastrozole). Aromatase inhibitors differ greatly from SERMs in their action and how they deal with the issues of estrogen control. The misunderstanding that SERMs, such as Nolvadex and Clomid, serve to lower estrogen levels must first be addressed before delving into any further details. This is a persistent rumor among the anabolic steroid using community that has begun to erode as of late, but the rumor still persists. SERMs serve to block the action of Estrogen at the receptor sites in breast tissue by occupying the receptor sites in place of Estrogen so that Estrogen itself cannot exert its effects there through receptor site binding. Conversely, SERMs will also act as Estrogens at receptor sites at other cells in other areas of the body (the liver, for example in Nolvadex’s case).
