Blood Pressure Medication
Antihypertensives are a class of drugs that are used to treat hypertension (high blood pressure). Antihypertensive therapy seeks to prevent the complications of high blood pressure, such as stroke, heart failure, kidney failure and myocardial infarction. Evidence suggests that a reduction of blood pressure by 5 mmHg can decrease the risk of stroke by 34% and of ischaemic heart disease by 21%. It can reduce the likelihood of dementia, heart failure, and mortality from cardiovascular disease. There are many classes of antihypertensives, which lower blood pressure by different means. Among the most important and most widely used medications are thiazide diuretics, calcium channel blockers, angiotensin-converting enzyme inhibitors (ACE inhibitors), angiotensin II receptor blockers or antagonists (ARBs), and beta blockers. Which type of medication to use initially for hypertension has been the subject of several large studies and resulting national guidelines. The fundamental ...

Medication
Medication (also called medicament, medicine, pharmaceutical drug, medicinal product, medicinal drug or simply drug) is a drug used to medical diagnosis, diagnose, cure, treat, or preventive medicine, prevent disease. Drug therapy (pharmacotherapy) is an important part of the medicine, medical field and relies on the science of pharmacology for continual advancement and on pharmacy for appropriate management. Drugs are Drug class, classified in many ways. One of the key divisions is by level of controlled substance, control, which distinguishes prescription drugs (those that a pharmacist dispenses only on the medical prescription) from over-the-counter drugs (those that consumers can order for themselves). Medicines may be classified by mode of action, route of administration, biological system affected, or therapeutic effects. The World Health Organization keeps a list of essential medicines. Drug discovery and drug development are complex and expensive endeavors undertake ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
First-line Treatment
A therapy or medical treatment is the attempted remediation of a health problem, usually following a medical diagnosis. Both words, ''treatment'' and ''therapy'', are often abbreviated tx, Tx, or Tx. As a rule, each therapy has indications and contraindications. There are many different types of therapy. Not all therapies are effective. Many therapies can produce unwanted adverse effects. ''Treatment'' and ''therapy'' are often synonymous, especially in the usage of health professionals. However, in the context of mental health, the term ''therapy'' may refer specifically to psychotherapy. Semantic field The words ''care'', ''therapy'', ''treatment'', and ''intervention'' overlap in a semantic field, and thus they can be synonymous depending on context. Moving rightward through that order, the connotative level of holism decreases and the level of specificity (to concrete instances) increases. Thus, in health-care contexts (where its senses are always noncount), th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bendroflumethiazide
Bendroflumethiazide, formerly bendrofluazide, trade name Aprinox, is a thiazide diuretic used to treat hypertension. Bendroflumethiazide is a thiazide diuretic which works by inhibiting sodium reabsorption at the beginning of the distal convoluted tubule (DCT). Water is lost as a result of more sodium reaching the collecting ducts. Bendroflumethiazide has a role in the treatment of mild heart failure although loop diuretics are better for reducing overload. The main use of bendroflumethiazide currently is in hypertension (part of the effect is due to vasodilation). It was patented in 1958 and approved for medical use in 1960. Adverse effects Common adverse effects: * feeling dizzy due to orthostatic hypotension *dry mouth or feeling thirsty *nausea * stomach ache *fatigue *diarrhea or constipation *joint pain due to gout Rare adverse effects: * thrombocytopenia * agranulocytosis * photosensitivity rash * pancreatitis * chronic kidney disease Chronic kidney disease (CKD ...

Chlorothiazide
Chlorothiazide, sold under the brand name Diuril among others, is an organic compound used as a diuretic and as an antihypertensive. It is used both within the hospital setting or for personal use to manage excess fluid associated with congestive heart failure. Most often taken in pill form, it is usually taken orally once or twice a day. In the ICU setting, chlorothiazide is given to diurese a patient in addition to furosemide (Lasix). Working in a separate mechanism from furosemide and absorbed enterically as a reconstituted suspension administered through a nasogastric tube (NG tube), the two drugs potentiate one another. It was patented in 1956 and approved for medical use in 1958. It is on the World Health Organization's List of Essential Medicines. Indications * Large amount of excess fluid including: **Heart failure **Peripheral edema **Hypertension Contraindications *Anuria * Allergies to sulfa drugs Side effects * Nausea / Vomiting * Headache * Dizziness * ...

Hydrochlorothiazide
Hydrochlorothiazide, sold under the brand name Hydrodiuril among others, is a diuretic medication used to treat hypertension and swelling due to fluid build-up. Other uses include treating diabetes insipidus and renal tubular acidosis and to decrease the risk of kidney stones in those with a high calcium level in the urine. Hydrochlorothiazide is taken by mouth and may be combined with other blood pressure medications as a single pill to increase effectiveness. Hydrochlorothiazide is a thiazide medication which inhibits reabsorption of sodium and chloride ions from the distal convoluted tubules of the kidneys, causing a natriuresis. This initially increases urine volume and lowers blood volume. It is believed to reduce peripheral vascular resistance. Potential side effects include poor kidney function, electrolyte imbalances, including low blood potassium, and, less commonly, low blood sodium, gout, high blood sugar, and feeling lightheaded with standing.

Thiazide
Thiazide () refers to both a class of sulfur-containing organic molecules and a class of diuretics based on the chemical structure of benzothiadiazine. The thiazide drug class was discovered and developed at Merck and Co. in the 1950s. The first approved drug of this class, chlorothiazide, was marketed under the trade name Diuril beginning in 1958. In most countries, thiazides are the least expensive antihypertensive drugs available. Thiazide organic molecules are bi-cyclic structures that contain adjacent sulfur and nitrogen atoms on one ring. Confusion sometimes occurs because thiazide-like diuretics such as indapamide are referred to as thiazides despite not having the thiazide chemical structure. When used this way, "thiazide" refers to a drug which acts at the thiazide receptor. The thiazide receptor is a Sodium-chloride symporter, sodium-chloride transporter that pulls Sodium chloride, NaCl from the Lumen (anatomy), lumen in the distal convoluted tubule.

Torsemide
Torasemide, also known as torsemide, is a diuretic medication used to treat fluid overload due to heart failure, kidney disease, and liver disease. It is a less preferred treatment for high blood pressure. It is taken by mouth or by injection into a vein. Common side effects include headache, increased urination, diarrhea, cough, and dizziness. Other side effects may include hearing loss and low blood potassium. Torasemide is a sulfonamide and loop diuretic. Use is not recommended in pregnancy or breastfeeding. It works by decreasing the reabsorption of sodium by the kidneys. Torasemide was patented in 1974 and came into medical use in 1993. It is on the World Health Organization's List of Essential Medicines. It is available as a generic medication. In 2022, it was the 184th most commonly prescribed medication in the United States, with more than 2million prescriptions. Medical uses It is used to treat fluid overload due to heart failure.

Furosemide
Furosemide, sold under the brand name Lasix among others, is a loop diuretic medication used to treat edema due to heart failure, liver scarring, or kidney disease. Furosemide may also be used for the treatment of high blood pressure. It can be taken intravenously or orally. When given intravenously, furosemide typically takes effect within five minutes; when taken orally, it typically metabolizes within an hour. Common side effects include orthostatic hypotension (decrease in blood pressure while standing, and associated lightheadedness), tinnitus (ringing in the ears), and photosensitivity (sensitivity to light). Potentially serious side effects include electrolyte abnormalities, low blood pressure, and hearing loss. It is recommended that serum electrolytes (especially potassium), serum , creatinine, BUN levels, and liver and kidney functioning be monitored in patients taking furosemide. It is also recommended to be alert for the occurrence of any potential blood d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethacrynic Acid
Etacrynic acid ( INN) or ethacrynic acid ( USAN), trade name Edecrin, is a loop diuretic used to treat high blood pressure and the swelling caused by diseases like congestive heart failure, liver failure, and kidney failure. A disadvantage with ethacrynic acid, compared to the other loop diuretic drugs such as furosemide, is that it has a significantly steep dose-response curve. This means the drug's dosing is very important as small variance in dose can cause a significant difference in the biological response. Unlike the other loop diuretics, etacrynic acid is not a sulfonamide and may thus be used in individuals with sulfa allergies in whom the sulfonamide loop diuretics would be contraindicated. Structural features Ethacrynic acid is a phenoxyacetic acid derivative, and contains an α,β-unsaturated ketone group. Medical use Ethacrynic acid is a diuretic that is used to treat edema when a stronger agent is required. It is available as a pill or injected form. The pill i ...

Loop Diuretic
Loop diuretics are pharmacological agents that primarily inhibit the Na-K-Cl cotransporter located on the luminal membrane of cells along the thick ascending limb of the loop of Henle. They are often used for the treatment of hypertension and edema secondary to congestive heart failure, liver cirrhosis, or chronic kidney disease. While thiazide diuretics are more effective in patients with normal kidney function, loop diuretics are more effective in patients with impaired kidney function. Mechanism of action Loop diuretics are 90% bonded to proteins and are secreted into the proximal convoluted tubule through organic anion transporter 1 (OAT-1), OAT-2, and ABCC4. Loop diuretics act on the Na+-K+-2Cl− symporter (NKCC2) in the thick ascending limb of the loop of Henle to inhibit sodium, chloride and potassium reabsorption. This is achieved by competing for the Cl− binding site. Loop diuretics also inhibit NKCC2 at macula densa, reducing sodium transported into macula ...
