Daflon
Daflon is an oral micronized purified phlebotonic flavonoid fraction containing 90% diosmin and 10% hesperidin. It is manufactured by Laboratoires Servier and often used to treat or manage disorders of the blood vessels. Flavonoids are a type of phytochemical that have been associated with various effects on human health and are a component of many different pharmaceutical, nutraceutical, and cosmetic preparations. Diosmin is a flavone glycoside that is derived from hesperidin. Hesperidin is a flavone that is extracted from citrus fruits. Vein diseases and hemorrhoids Daflon is not an FDA-approved medication, and therefore it cannot be advertised for treatment of diseases in the United States. Daflon is under preliminary research for its potential use in treating vein diseases, or hemorrhoids. It is sold as a drug in France, Spain, Malaysia, Portugal and Belgium. There is moderate certainty evidence for the effectiveness of daflon for slightly reducing oedema compared to placebo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diosmin
Diosmin (diosmetin 7-O-rutinoside), a flavone glycoside of diosmetin, is manufactured from citrus fruit peels as a phlebotonic non-prescription dietary supplement used to aid treatment of hemorrhoids or chronic venous diseases, mainly of the legs. Uses Diosmin is a dietary supplement used to aid treatment of hemorrhoids and venous diseases, i.e., chronic venous insufficiency including spider and varicose veins, leg swelling (edema), stasis dermatitis and venous ulcers. The mechanism of action of Diosmin and other phlebotonics is undefined, and clinical evidence of benefit is limited. Diosmin is not recommended for treating the rectal mucosa, skin irritations, or wounds, and should not be used to treat dermatitis, eczema, or urticaria. Diosmin is not recommended for use in children or women during pregnancy. There is moderate-quality evidence that diosmin or other phlebotonics improved leg and ankle swelling and lower leg pain, and low-quality evidence for treating hemorrhoi ...

Chronic Venous Insufficiency
Chronic venous insufficiency (CVI) is a medical condition characterized by blood pooling in the veins, leading to increased pressure and strain on the vein walls. The most common cause of CVI is superficial venous reflux, which often results in the formation of varicose veins, a treatable condition. Since functional venous valves are necessary to facilitate efficient Venous return, blood return from the lower extremities, CVI primarily affects the legs. When impaired vein function leads to significant symptoms such as oedema (swelling) or venous ulcer formation, the condition is referred to as chronic venous disease. It is also known as ''chronic peripheral venous insufficiency'' and should not be confused with post-thrombotic syndrome, a separate condition caused by damage to the deep veins following deep vein thrombosis (DVT). Most cases of CVI can be managed or improved through treatments targeting the superficial venous system or stenting the deep venous system. For instanc ...

Flavonoid
Flavonoids (or bioflavonoids; from the Latin word ''flavus'', meaning yellow, their color in nature) are a class of polyphenolic secondary metabolites found in plants, and thus commonly consumed in the diets of humans. Chemically, flavonoids have the general structure of a 15-carbon skeleton, which consists of two phenyl rings (A and B) and a Heterocyclic compound, heterocyclic ring (C, the ring containing the embedded oxygen). This carbon structure can be abbreviated C6-C3-C6. According to the IUPAC nomenclature, they can be classified into: *flavonoids or bioflavonoids *isoflavonoids, derived from 3-phenylchromone, chromen-4-one (3-phenyl-1,4-benzopyran, benzopyrone) structure *neoflavonoids, derived from 4-phenylcoumarin (4-phenyl-1,2-benzopyran, benzopyrone) structure The three flavonoid classes above are all ketone-containing compounds and as such, anthoxanthins (flavones and flavonols). This class was the first to be termed bioflavonoids. The terms flavonoid and bioflavo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drug Interaction
In pharmaceutical sciences, drug interactions occur when a drug's mechanism of action is affected by the concomitant administration of substances such as foods, beverages, or other drugs. A popular example of drug–food interaction is the effect of grapefruit on the metabolism of drugs. Interactions may occur by simultaneous targeting of receptors, directly or indirectly. For example, both Zolpidem and alcohol affect GABAA receptors, and their simultaneous consumption results in the overstimulation of the receptor, which can lead to loss of consciousness. When two drugs affect each other, it is a drug–drug interaction (DDI). The risk of a DDI increases with the number of drugs used. A large share of elderly people regularly use five or more medications or supplements, with a significant risk of side-effects from drug–drug interactions. Drug interactions can be of three kinds: * additive (the result is what you expect when you add together the effect of each drug take ...

Gastric Disorder
Stomach diseases include gastritis, gastroparesis, Crohn's disease and various cancers. The stomach is an important organ in the body. It plays a vital role in digestion of foods, releases various enzymes and also protects the lower intestine from harmful organisms. The stomach connects to the esophagus above and to the small intestine below. It is intricately related to the pancreas, spleen and liver. The stomach does vary in size but its J shape is constant. The stomach lies in the upper part of the abdomen just below the left rib cage. The term ''gastropathy'' means "stomach disease" and is included in the name of the diseases portal hypertensive gastropathy, hyperplastic hypersecretory gastropathy (Ménétrier's disease), and others. However, not all stomach diseases are labeled with the word "gastropathy"; examples include peptic ulcer disease, gastroparesis, and dyspepsia. Many stomach diseases are associated with infections. In the past it was widely but incorrectly beli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thromboxane
Thromboxane is a member of the family of lipids known as eicosanoids. The two major thromboxanes are thromboxane A2 and thromboxane B2. The distinguishing feature of thromboxanes is a 6-membered ether-containing ring. Thromboxane is named for its role in blood clot formation (thrombosis). Production Thromboxane-A synthase, an enzyme found in platelets, converts the arachidonic acid derivative prostaglandin H2 to thromboxane. People with asthma tend to have increased thromboxane production, and analogs of thromboxane act as bronchoconstrictors in patients with asthma. Mechanism Thromboxane acts by binding to any of the thromboxane receptors, G-protein-coupled receptors coupled to the G protein Gq. Functions Thromboxane is a vasoconstrictor and a potent hypertensive agent, and it facilitates platelet aggregation. It is in homeostatic balance in the circulatory system with prostacyclin, a related compound. The mechanism of secretion of thromboxanes from platelets is s ...

Prostaglandin E2
Prostaglandin E2 (PGE2), also known as dinoprostone, is a naturally occurring prostaglandin with oxytocic properties that is used as a medication. Dinoprostone is used in labor induction, bleeding after delivery, termination of pregnancy, and in newborn babies to keep the ductus arteriosus open. In babies it is used in those with congenital heart defects until surgery can be carried out. It is also used to manage gestational trophoblastic disease. It may be used within the vagina or by injection into a vein. PGE2 synthesis within the body begins with the activation of arachidonic acid (AA) by the enzyme phospholipase A2. Once activated, AA is oxygenated by cyclooxygenase (COX) enzymes to form prostaglandin endoperoxides. Specifically, prostaglandin G2 (PGG2) is modified by the peroxidase moiety of the COX enzyme to produce prostaglandin H2 (PGH2) which is then converted to PGE2. Common side effects of PGE2 include nausea, vomiting, diarrhea, fever, and excessi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Venous Stasis
Venous stasis, or venostasis, is a condition of slow blood flow in the veins, usually of the legs. Presentation Complications Potential complications of venous stasis are: * Venous ulcers * Blood clot formation in veins (venous thrombosis), that can occur in the deep veins of the legs (deep vein thrombosis, DVT) or in the superficial veins * Id reactions Causes Causes of venous stasis include: * Obesity * Pregnancy * Previous damage to leg * Blood clot * Smoking * Swelling and inflammation of a vein close to the skin * Congestive heart failure. * Long periods of immobility that can be encountered from driving, flying, bed rest/hospitalization, or having an orthopedic cast. Recommendations by clinicians to reduce venous stasis and DVT/PE often encourage increasing walking, calf exercises, and intermittent pneumatic compression Intermittent pneumatic compression is a therapeutic technique used in medical devices that include an air pump and inflatable auxiliary sleeves, gloves ...

Edema
Edema (American English), also spelled oedema (British English), and also known as fluid retention, swelling, dropsy and hydropsy, is the build-up of fluid in the body's tissue (biology), tissue. Most commonly, the legs or arms are affected. Symptoms may include skin that feels tight, the area feeling heavy, and joint stiffness. Other symptoms depend on the underlying cause. Causes may include Chronic venous insufficiency, venous insufficiency, heart failure, kidney problems, hypoalbuminemia, low protein levels, liver problems, deep vein thrombosis, infections, kwashiorkor, angioedema, certain medications, and lymphedema. It may also occur in immobile patients (stroke, spinal cord injury, aging), or with temporary immobility such as prolonged sitting or standing, and during menstruation or pregnancy. The condition is more concerning if it starts suddenly, or pain or shortness of breath is present. Treatment depends on the underlying cause. If the underlying mechanism involve ...

Perivascular
Mural cells are the generalized name of cell population in the microcirculation that is comprised of vascular smooth muscle cells (vSMCs), and pericytes. Both types are in close contact with the endothelial cells lining the capillaries, and are important for vascular development and stability. The vasculature is a system of small, interconnected tubes that ensure there is proper blood flow to all of the organs.Mural cells are involved in the formation of normal vasculature and are responsive to factors including platelet-derived growth factor B (PDGFB) and vascular endothelial growth factor (VEGF). The weakness and disorganization of tumor vasculature is partly due to the inability of tumors to recruit properly organized mural cells. Function during angiogenesis Mural cells, like pericytes, are important for how blood vessels work. During the growth of new blood vessels (a process called angiogenesis), pericytes help guide how endothelial cells grow and divide. This process rel ...
