Butamide
Tolbutamide is a first-generation potassium channel blocker, sulfonylurea oral hypoglycemic medication. This drug may be used in the management of type 2 diabetes if diet alone is not effective. Tolbutamide stimulates the secretion of insulin by the pancreas. It is not routinely used due to a higher incidence of adverse effects compared to newer, second-generation sulfonylureas, such as Glibenclamide. It generally has a short duration of action due to its rapid metabolism, so is safe for use in older people. It was discovered in 1956. Side effects # Hypoglycemia # Weight gain # Hypersensitivity: cross-allergicity with sulfonamides # Drug interactions (especially first-generation drugs): Increased hypoglycemia with cimetidine, insulin, salicylates, and sulfonamides Salicylates displace tolbutamide from its binding site on plasma binding proteins which lead to increase in free tolbutamide concentration, thus hypoglycemic shock. History Orinase was developed by Upjohn Co. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liver
The liver is a major Organ (anatomy), organ only found in vertebrates which performs many essential biological functions such as detoxification of the organism, and the Protein biosynthesis, synthesis of proteins and biochemicals necessary for digestion and growth. In humans, it is located in the quadrant (anatomy), right upper quadrant of the abdomen, below the thoracic diaphragm, diaphragm. Its other roles in metabolism include the regulation of Glycogen, glycogen storage, decomposition of red blood cells, and the production of hormones. The liver is an accessory digestive organ that produces bile, an alkaline fluid containing cholesterol and bile acids, which helps the fatty acid degradation, breakdown of fat. The gallbladder, a small pouch that sits just under the liver, stores bile produced by the liver which is later moved to the small intestine to complete digestion. The liver's highly specialized biological tissue, tissue, consisting mostly of hepatocytes, regulates a w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Convulsions
A convulsion is a medical condition where the body muscles contract and relax rapidly and repeatedly, resulting in uncontrolled shaking. Because epileptic seizures typically include convulsions, the term ''convulsion'' is sometimes used as a synonym for ''seizure''. However, not all epileptic seizures lead to convulsions, and not all convulsions are caused by epileptic seizures. Convulsions are also consistent with an electric shock and improper enriched air scuba diving. Non-epileptic convulsions have no relation with epilepsy, and are caused by non-epileptic seizures. Convulsion is a common term generally describing uncontrollable muscle contractions. The term convulsion has been used interchangeably with the word "seizure". Seizures may cause a person to have convulsions, but this is not always the case. Convulsion is a type of seizure that involves bursts of electrical activity in the brain. Occasionally the reason for a convulsion is unfamiliar. A convulsion may be caused ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potassium Channel Blockers
Potassium channel blockers are agents which interfere with conduction through potassium channels. Medical uses Arrhythmia Potassium channel blockers used in the treatment of cardiac arrhythmia are classified as class III antiarrhythmic agents. Mechanism Class III agents predominantly block the potassium channels, thereby prolonging repolarization. More specifically, their primary effect is on IKr. Since these agents do not affect the sodium channel, conduction velocity is not decreased. The prolongation of the action potential duration and refractory period, combined with the maintenance of normal conduction velocity, prevent re-entrant arrhythmias. (The re-entrant rhythm is less likely to interact with tissue that has become refractory). Examples and uses *Amiodarone is indicated for the treatment of refractory VT or VF, particularly in the setting of acute ischemia. Amiodarone is also safe to use in individuals with cardiomyopathy and atrial fibrillation, to main ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disulfiram-like Drugs
A disulfiram-like drug is a drug that causes an adverse reaction to alcohol leading to nausea, vomiting, flushing, dizziness, throbbing headache, chest and abdominal discomfort, and general hangover-like symptoms among others. These effects are caused by accumulation of acetaldehyde, a major but toxic metabolite of alcohol formed by the enzyme alcohol dehydrogenase. The reaction has been variously termed a ''disulfiram-like reaction'', ''alcohol intolerance'', and ''acetaldehyde syndrome''.Mutalik, M., & Sanghavi, D. (2014). ''Review of Drug Interactions: A Comprehensive Update''. The prototypical drug of this group is disulfiram (brand name Antabuse), which acts as an acetaldehyde dehydrogenase inhibitor, preventing the metabolism of acetaldehyde into acetic acid, and is used in the treatment of alcoholism. A variety of other drugs cause disulfiram-like reactions upon consumption of alcohol as unintended drug interactions and side effects. Many disulfiram-like drugs act as inh ...

Chlorpropamide
Chlorpropamide is a drug in the sulfonylurea class used to treat diabetes mellitus type 2. It is a long-acting first-generation sulfonylurea. Mechanism of action Like other sulfonylureas, chlorpropamide acts to increase the secretion of insulin, so it is only effective in patients who have some pancreas, pancreatic beta cell function. It can cause relatively long episodes of hypoglycemia; this is one reason why shorter-acting sulfonylureas such as gliclazide or tolbutamide are used instead. The risk of hypoglycemia makes this drug a poor choice for the Old age, elderly and patients with mild to moderate liver, hepatic and kidney, renal impairment. Chlorpropamide is also used in partial central diabetes insipidus. Pharmacokinetics Cmax (pharmacology), Maximal plasma concentrations are reached 3 to 5 hours after quick and nearly complete (>90%) resorption from the gut. Blood plasma, Plasma half life is 36 hours; the drug is effective for about 24 hours, longer than other sulfonylur ... [...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 ...

Hoechst AG
Hoechst AG () was a German chemicals then life-sciences company that became Aventis Deutschland after its merger with France's Rhône-Poulenc S.A. in 1999. With the new company's 2004 merger with Sanofi-Synthélabo, it became a subsidiary of the resulting Sanofi-Aventis pharmaceuticals group. History The company was founded in 1863 as "Teerfarbenfabrik Meister, Lucius & Co." in Höchst, near Frankfurt and changed its name some years later to "Teerfarbenfabrik Meister Lucius & Brüning". In 1880 it became a stock company "Farbwerke vorm. Meister Lucius & Brüning AG". For the international market the name was simplified to "Farbwerke Hoechst AG". Until 1925 the Hoechst AG was independent. In 1916, the Hoechst AG was one of the co-founders of IG Farben, an advocacy group of Germany's chemicals industry to gain industrial power during and after World War I.

Pharmacia
Pharmacia was a pharmaceutical and biotechnological company in Sweden that merged with the American pharmaceutical company Upjohn in 1995. History Pharmacia company was founded in 1911 in Stockholm, Sweden by pharmacist Gustav Felix Grönfeldt at the ''Elgen'' Pharmacy. The company is named after the Greek word φαρμακεία, transliterated ''pharmakeia'', which means 'sorcery'. In the company's early days, much of its profits were derived from the "miracle medicine" Phospho-Energon. During World War II, Swedish chemist Björn Ingelman (who worked for Arne Tiselius at Uppsala university) researched various uses for the polysaccharide dextran. Together with the medical researcher Anders Grönwall, he discovered that dextran could be used as a replacement for blood plasma in blood transfusions, for which there could be a large need in wartime. Pharmacia, which then was still a small company, was contacted in 1943 and its CEO Elis Göth was very interested. The product Macrod ...
