Pravastatin Or Atorvastatin Evaluation And Infection Therapy - Thrombolysis In Myocardial Infarction
Pravastatin, sold under the brand name Pravachol among others, is a statin medication, used for preventing cardiovascular disease in those at high risk and treating abnormal lipids. It should be used together with diet changes, exercise, and weight loss. It is taken by mouth. Common side effects include joint pain, diarrhea, nausea, headaches, and muscle pains. Serious side effects may include rhabdomyolysis, liver problems, and diabetes. Use during pregnancy may harm the baby. Like all statins, pravastatin works by inhibiting HMG-CoA reductase, an enzyme found in liver that plays a role in producing cholesterol. Pravastatin was patented in 1980 and approved for medical use in 1989. It is on the World Health Organization's List of Essential Medicines. It is available as a generic medication. In 2020, it was the 34th most commonly prescribed medication in the United States, with more than 17million prescriptions. Medical uses Pravastatin is primarily used for the treatment o ...

Oral Administration
Oral administration is a route of administration where a substance is taken through the mouth. Per os abbreviated to P.O. is sometimes used as a direction for medication to be taken orally. Many medications are taken orally because they are intended to have a systemic effect, reaching different parts of the body via the bloodstream, for example. Oral administration can be easier and less painful than other routes, such as injection. However, the onset of action is relatively low, and the effectiveness is reduced if it is not absorbed properly in the digestive system, or if it is broken down by digestive enzymes before it can reach the bloodstream. Some medications may cause gastrointestinal side effects, such as nausea or vomiting, when taken orally. Oral administration can also only be applied to conscious patients, and patients willing and able to swallow. Terminology ''Per os'' (; ''P.O.'') is an adverbial phrase meaning literally from Latin "through the mouth" or "by mouth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jaundice
Jaundice, also known as icterus, is a yellowish or greenish pigmentation of the skin and sclera due to high bilirubin levels. Jaundice in adults is typically a sign indicating the presence of underlying diseases involving abnormal heme metabolism, liver dysfunction, or biliary-tract obstruction. The prevalence of jaundice in adults is rare, while jaundice in babies is common, with an estimated 80% affected during their first week of life. The most commonly associated symptoms of jaundice are itchiness, pale feces, and dark urine. Normal levels of bilirubin in blood are below 1.0 mg/ dl (17 μmol/ L), while levels over 2–3 mg/dl (34–51 μmol/L) typically result in jaundice. High blood bilirubin is divided into two types – unconjugated and conjugated bilirubin. Causes of jaundice vary from relatively benign to potentially fatal. High unconjugated bilirubin may be due to excess red blood cell breakdown, large bruises, genetic conditions s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Darunavir
Darunavir (DRV), sold under the brand name Prezista among others, is an antiretroviral medication used to treat and prevent HIV/AIDS. It is generally recommended for use with other antiretrovirals. It is often used with low doses of ritonavir or cobicistat to increase darunavir levels. It may be used for prevention after a needlestick injury or other potential exposure. It is taken by mouth once to twice a day. Common side effects include diarrhea, nausea, abdominal pain, headache, rash and vomiting. Severe side effects include allergic reactions, liver problems, and skin rashes such as toxic epidermal necrolysis. While poorly studied in pregnancy it appears to be safe for the baby. It is of the protease inhibitor (PI) class and works by blocking HIV protease. Developed by pharmaceutical company Tibotec, darunavir is named after Arun K. Ghosh, the chemistry professor who discovered the molecule at the University of Illinois at Chicago. It was approved by the Food and Drug Adm ...

Ritonavir
Ritonavir, sold under the brand name Norvir, is an antiretroviral drug used along with other medications to treat HIV/AIDS. This combination treatment is known as highly active antiretroviral therapy (HAART). Ritonavir is a protease inhibitor and is used with other protease inhibitor (pharmacology), protease inhibitors. It may also be used in combination with other medications to treat hepatitis C and COVID-19. It is taken Oral administration, by mouth. Tablets of ritonavir are not bioequivalent to capsules, as the tablets may result in higher peak plasma concentrations. Common side effects include nausea, vomiting, loss of appetite, diarrhea, and numbness of the hands and feet. Serious side effects include liver problems, pancreatitis, allergic reactions, and arrythmias. Serious interactions may occur with a number of other medications including amiodarone and simvastatin. At low doses it is considered to be acceptable for use during pregnancy. Ritonavir is of the protease inh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lopinavir
Lopinavir is an antiretroviral of the protease inhibitor class. It is used against HIV infections as a fixed-dose combination with another protease inhibitor, ritonavir (lopinavir/ritonavir). It was patented in 1995 and approved for medical use in 2000. Side effects Side effects, interactions, and contraindications have only been evaluated in the drug combination lopinavir/ritonavir. Pharmacology Lopinavir is highly bound to plasma proteins (98–99%). Reports are contradictory regarding lopinavir penetration into the cerebrospinal fluid (CSF). Anecdotal reports state that lopinavir cannot be detected in the CSF; however, a study of paired CSF-plasma samples from 26 patients receiving lopinavir/ritonavir found lopinavir CSF levels above the IC50 in 77% of samples. Research A 2014 study indicates that lopinavir is effective against the human papilloma virus (HPV). The study used the equivalent of one tablet twice a day applied topically to the cervices of women with high- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HIV Protease Inhibitor
Protease inhibitors (PIs) are medications that act by interfering with enzymes that cleave proteins. Some of the most well known are antiviral drugs widely used to treat HIV/AIDS and hepatitis C. These protease inhibitors prevent viral replication by selectively binding to viral proteases (e.g. HIV-1 protease) and blocking proteolytic cleavage of protein precursors that are necessary for the production of infectious viral particles. Protease inhibitors that have been developed and are currently used in clinical practice include: * Antiretroviral HIV-1 protease inhibitors—class stem ** Amprenavir ** Atazanavir ** Darunavir ** Fosamprenavir ** Indinavir ** Lopinavir ** Nelfinavir ** Ritonavir ** Saquinavir ** Tipranavir * Hepatitis C virus NS3/ 4A protease inhibitors—class stem ** Asunaprevir ** Boceprevir ** Grazoprevir ** Glecaprevir ** Paritaprevir ** Simeprevir ** Telaprevir * Severe acute respiratory syndrome coronavirus 2 3-chymotrypsin-like protease inhibitors ** ...

Niacin (substance)
Niacin, also known as nicotinic acid, is an organic compound and a form of vitamin B3, an essential human nutrient. It can be manufactured by plants and animals from the amino acid tryptophan. Niacin is obtained in the diet from a variety of whole and processed foods, with highest contents in fortified packaged foods, meat, poultry, red fish such as tuna and salmon, lesser amounts in nuts, legumes and seeds. Niacin as a dietary supplement is used to treat pellagra, a disease caused by niacin deficiency. Signs and symptoms of pellagra include skin and mouth lesions, anemia, headaches, and tiredness. Many countries mandate its addition to wheat flour or other food grains, thereby reducing the risk of pellagra. The amide derivative nicotinamide (niacinamide) is a component of the coenzymes nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP+). Although niacin and nicotinamide are identical in their vitamin activity, nicotinamide doe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cholestyramine
Colestyramine ( INN) or cholestyramine ( USAN) (trade names Questran, Questran Light, Cholybar, Olestyr) is a bile acid sequestrant, which binds bile in the gastrointestinal tract to prevent its reabsorption. It is a strong ion exchange resin, which means it can exchange its chloride anions with anionic bile acids in the gastrointestinal tract and bind them strongly in the resin matrix. The functional group of the anion exchange resin is a quaternary ammonium group attached to an inert styrene- divinylbenzene copolymer. Colestyramine removes bile acids from the body by forming insoluble complexes with bile acids in the intestine, which are then excreted in the feces. As a result of this loss of bile acids, more plasma cholesterol is converted to bile acids in the liver to normalise levels.http://livertox.nih.gov/Cholestyramine.htm, United States National Institutes of Health (page visited on 22 June 2016). This conversion of cholesterol into bile acids lowers plasma cholesterol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gemfibrozil
Gemfibrozil, sold under the brand name Lopid among others, is a medication used to treat abnormal blood lipid levels. It is generally less preferred than statins. Use is recommended together with dietary changes and exercise. It is unclear if it changes the risk of heart disease. It is taken by mouth. Common side effects include headache, dizziness, feeling tired, and intestinal upset. Serious side effects may include angioedema, gallstones, liver problems, and muscle breakdown. Use in pregnancy and breastfeeding is of unclear safety. It belongs to the fibrates group of medications and works by decreasing the breakdown of lipids in fat cells. Gemfibrozil was patented in 1968 and came into medical use in 1982. It is available as a generic medication. In 2020, it was the 189th most commonly prescribed medication in the United States, with more than 2million prescriptions. Medical uses *Hyperlipidemia (Type III) *Hypertriglyceridemia (Type IV): Gemfibrozil, though not as e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fenofibrate
Fenofibrate (sold under the brand names ''Tricor'', ''Fenobrat'' etc.), is an oral medication of the fibrate class used to treat abnormal blood lipid levels. It is less commonly used compared than statins because it treats a different type of cholesterol abnormality to statins. While statins have strong evidence for reducing heart disease and death, there is evidence to suggest that fenofibrate also reduces to the risk of heart disease and death. However, this seems only to apply to specific populations of people with elevated triglyceride levels and reduced high-density lipoprotein (HDL) cholesterol. Its use is recommended together with dietary changes. Common side effects include liver problems, breathing problems, abdominal pain, muscle problems, and nausea. Serious side effects may include toxic epidermal necrolysis, rhabdomyolysis, gallstones, and pancreatitis. Use during pregnancy and breastfeeding is not recommended. It works by multiple mechanisms. It was patented i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ketoconazole
Ketoconazole, sold under the brand name Nizoral among others, is an antiandrogen and antifungal medication used to treat a number of fungal infections. Applied to the skin it is used for fungal skin infections such as tinea, cutaneous candidiasis, pityriasis versicolor, dandruff, and seborrheic dermatitis. Taken by mouth it is a less preferred option and only recommended for severe infections when other agents cannot be used. Other uses include treatment of excessive male-patterned hair growth in women and Cushing's syndrome. Common side effects when applied to the skin include redness. Common side effects when taken by mouth include nausea, headache, and liver problems. Liver problems may result in death or the need for a liver transplantation. Other severe side effects when taken by mouth include QT prolongation, adrenocortical insufficiency, and anaphylaxis.

Cyclosporine
Ciclosporin, also spelled cyclosporine and cyclosporin, is a calcineurin inhibitor, used as an immunosuppressant medication. It is a natural product. It is taken orally or intravenously for rheumatoid arthritis, psoriasis, Crohn's disease, nephrotic syndrome, and in organ transplants to prevent rejection. It is also used as eye drops for keratoconjunctivitis sicca (dry eyes). Common side effects include high blood pressure, headache, kidney problems, increased hair growth, and vomiting. Other severe side effects include an increased risk of infection, liver problems, and an increased risk of lymphoma. Blood levels of the medication should be checked to decrease the risk of side effects. Use during pregnancy may result in preterm birth; however, ciclosporin does not appear to cause birth defects. Ciclosporin is believed to work by decreasing the function of lymphocytes. It does this by forming a complex with cyclophilin to block the phosphatase activity of calcineuri ...
