Blood pressure (BP) is the pressure of circulating blood against the walls of blood vessels. Most of this pressure results from the heart pumping blood through the circulatory system. When used without qualification, the term "blood pressure" refers to the pressure in the large arteries. Blood pressure is usually expressed in terms of the systolic pressure over diastolic pressure in the cardiac cycle. It is measured in millimeters of mercury (mmHg) above the surrounding atmospheric pressure.
Loperamide, sold under the brand name Imodium, among others, is a medication used to decrease the frequency of diarrhea. It is often used for this purpose in inflammatory bowel disease and short bowel syndrome. It is not recommended for those with blood in the stool, mucus in the stool, or fevers. The medication is taken by mouth.
Mercury poisoning is a type of metal poisoning due to exposure to mercury. Symptoms depend upon the type, dose, method, and duration of exposure. They may include muscle weakness, poor coordination, numbness in the hands and feet, skin rashes, anxiety, memory problems, trouble speaking, trouble hearing, or trouble seeing. High-level exposure to methylmercury is known as Minamata disease. Methylmercury exposure in children may result in acrodynia in which the skin becomes pink and peels. Long-term complications may include kidney problems and decreased intelligence. The effects of long-term low-dose exposure to methylmercury are unclear.
Pulmonary edema(PE), also known as pulmonary congestion, is liquid accumulation in the tissue and air spaces of the lungs. It leads to impaired gas exchange and may cause respiratory failure. It is due to either failure of the left ventricle of the heart to remove blood adequately from the pulmonary circulation, or an injury to the lung tissue or blood vessels of the lung.
Septic shock is a potentially fatal medical condition that occurs when sepsis, which is organ injury or damage in response to infection, leads to dangerously low blood pressure and abnormalities in cellular metabolism. The Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3) defines septic shock as a subset of sepsis in which particularly profound circulatory, cellular, and metabolic abnormalities are associated with a greater risk of mortality than with sepsis alone. Patients with septic shock can be clinically identified by requiring a vasopressor to maintain a mean arterial pressure of 65 mm Hg or greater and having serum lactate level greater than 2 mmol/L (>18 mg/dL) in the absence of hypovolemia. This combination is associated with hospital mortality rates greater than 40%.
Rosiglitazone 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 heart attack, sales plummeted to just $9.5-million in 2012. The drug's patent expired in 2012.
Pergolide, sold under the brand name Permax and Prascend (veterinary) among others, is an ergoline-based dopamine receptor agonist used in some countries for the treatment of Parkinson's disease. Parkinson's disease is associated with reduced dopamine activity in the substantia nigra of the brain. Pergolide acts on many of the same receptors as dopamine to increase receptor activity.
Chelation therapy is a medical procedure that involves the administration of chelating agents to remove heavy metals from the body. Chelation therapy has a long history of use in clinical toxicology and remains in use for some very specific medical treatments, although it is administered under very careful medical supervision due to various inherent risks, including the mobilization of mercury and other metals through the brain and other parts of the body by the use of weak chelating agents that unbind with metals before elimination, exacerbating existing damage. To avoid mobilization, some practitioners of chelation use strong chelators, such as selenium, taken at low doses over a long period of time.
Nimodipine, sold under the brand name Nimotop among others, is calcium channel blocker used in preventing vasospasm secondary to subarachnoid hemorrhage. It was originally developed within the calcium channel blocker class as it was used for the treatment of high blood pressure, but is not used for this indication.
Methylmercury (sometimes methyl mercury) is an organometallic cation with the formula [CH3Hg]+. Methylmercury is extremely toxic, and its derivatives are the major source of organic mercury for humans. It is a bioaccumulative environmental toxicant.
Glycopyrronium bromide is a medication of the muscarinic anticholinergic group. It does not cross the blood–brain barrier and consequently has few to no central effects. It is available in oral, intravenous, topical, and inhaled forms. It is a synthetic quaternary ammonium compound.
Isosorbide dinitrate/hydralazine is a fixed dose combination drug treatment specifically approved by the US FDA to be used to treat self-identified black people with congestive heart failure. It is a combination of hydralazine and isosorbide dinitrate. It is the first race-based prescription drug in the United States.
Dronedarone, sold under the brand name Multaq, is a medication by Sanofi-Aventis, mainly for the indication of cardiac arrhythmias. It was approved by the FDA on July 2, 2009. It was recommended as an alternative to amiodarone for the treatment of atrial fibrillation and atrial flutter in people whose hearts have either returned to normal rhythm or who undergo drug therapy or electric shock treatment i.e. direct current cardioversion (DCCV) to maintain normal rhythm. It is a class III antiarrhythmic drug. In the United States, the FDA approved label includes a claim for reducing hospitalization, but not for reducing mortality, as a reduction in mortality was not demonstrated in the clinical development program. A trial of the drug in heart failure was stopped as an interim analysis showed a possible increase in heart failure deaths, in patients with moderate to severe CHF.
Dental amalgam is a liquid mercury and metal alloy mixture used in dentistry to fill cavities caused by tooth decay. Low-copper amalgam commonly consists of mercury (50%), silver (~22–32%), tin (~14%), zinc (~8%) and other trace metals.
Dapagliflozin, sold under the brand names Farxiga (US) and Forxiga (EU) among others, is a medication used to treat type 2 diabetes. It is also used to treat adults with certain kinds of heart failure and chronic kidney disease.
Mercury is a chemical element with the symbol Hg and atomic number 80. It is commonly known as quicksilver and was formerly named hydrargyrum. A heavy, silvery d-block element, mercury is the only metallic element that is liquid at standard conditions for temperature and pressure; the only other element that is liquid under these conditions is the halogen bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature.
Empagliflozin, sold under the brand name Jardiance among others, is a medication used together with diet and exercise to treat type 2 diabetes. It can be prescribed instead of metformin and has benefits over sulfonylureas. It may be used together with other medications such as metformin or insulin. It is not recommended for type 1 diabetes. It is taken by mouth. In view of recent trial evidence, it is expected to soon receive licence to be used for patients with heart failure, irrespective of diabetic status. Jardiance can also be used in the treatment of coronary heart failure to reduce cardiovascular mortality.
Hurair Vasken Aposhian was a Ph.D. toxicologist and an emeritus professor of molecular and cell biology at the University of Arizona, a post he held beginning in 1975. He is also a former professor of pharmacology at the medical school at said university. He received his bachelor's degree in chemistry, at Brown University, 1948. He received a master's degree and a PhD in physiological chemistry at the University of Rochester, where he published some scientific studies about the synthesis of isoalloxazine ring-containing compounds. He did a postdoctoral with Nobel Laureate Arthur Kornberg in the department of biochemistry at Stanford University School of Medicine. He has done sabbatical scholar-in-residence at MIT and at the University of California at San Diego. He is best known for his pioneering work on Succimer and Unithiol in the treatment of arsenic, mercury, lead and other heavy metals leading to FDA approval of succimer in childhood lead poisoning at levels over 40 ug/dl. Previous posts he had held include at Vanderbilt, Tufts University, and the University of Maryland. His views about mercury in vaccines and in dental amalgams go against the consensus of the medical community and are controversial.
Finerenone, sold under the brand name Kerendia, is a medication used to reduce the risk of kidney function decline, kidney failure, cardiovascular death, non-fatal heart attacks, and hospitalization for heart failure in adults with chronic kidney disease associated with type 2 diabetes. Finerenone is a non-steroidal mineralocorticoid receptor antagonist (MRA).
Ventricular natriuretic peptide or brain natriuretic peptide (BNP), also known as B-type natriuretic peptide, is a hormone secreted by cardiomyocytes in the heart ventricles in response to stretching caused by increased ventricular blood volume.
