Isosorbide Dinitrate
Isosorbide dinitrate is a medication used for heart failure, esophageal spasms, and to treat and prevent angina pectoris. It has been found to be particularly useful in heart failure due to systolic dysfunction together with hydralazine. It is taken by mouth or under the tongue. Common side effects include headache, lightheadedness with standing, and blurred vision. Severe side effects include low blood pressure. It is unclear if use in pregnancy is safe for the baby. It should not be used together with PDE5 Inhibitors. Isosorbide dinitrate is in the nitrate family of medications and works by dilating blood vessels. Isosorbide dinitrate was first written about in 1939. It is on the World Health Organization's List of Essential Medicines. Isosorbide dinitrate is available as a generic medication. A long-acting form exists. In 2022, isosorbide was the 119th most commonly prescribed medication in the United States, with more than 5million prescriptions. Medical uses It ...

Oral Administration
Oral administration is a route of administration whereby a substance is taken through the Human mouth, mouth, swallowed, and then processed via the digestive system. This is a common route of administration for many medications. Oral administration can be easier and less painful than other routes of administration, such as Injection (medicine), 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 able to swallow. Terminology ''Per os'' (; ''P.O.'') is an adverbial phrase meaning literally from Latin "through the mouth" or "by mouth". The expression is used in medicine to describe a treatment that is taken orally (but not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Generic Medication
A generic drug is a pharmaceutical drug that contains the same chemical substance as a drug that was originally protected by chemical patents. Generic drugs are allowed for sale after the patents on the original drugs expire. Because the active chemical substance is the same, the medical profile of generics is equivalent in performance compared to their performance at the time when they were patented drugs. A generic drug has the same active pharmaceutical ingredient (API) as the original, but it may differ in some characteristics such as the manufacturing process, pharmaceutical formulation, formulation, excipients, color, taste, and packaging. Although they may not be associated with a particular company, generic drugs are usually subject to government regulations in the countries in which they are dispensed. They are labeled with the name of the manufacturer and a generic non-proprietary name such as the United States Adopted Name (USAN) or International nonproprietary name, Int ...

Antianginals
An antianginal is a Medication, drug used in the treatment of ''angina pectoris'', a symptom of coronary heart disease, ischaemic heart disease. Myocardial ischemia arises from the dysfunction of coronary macrovascular or microvascular components, leading to a compromised supply of oxygen and nutrients to the myocardium. The underlying pathophysiological mechanisms encompass a range of factors, including atherosclerosis in epicardial coronary arteries, vasospasm in large or small vessels, and microvascular dysfunction—whose clinical significance is increasingly acknowledged. The diverse clinical presentations of myocardial ischemia collectively fall under the term chronic coronary syndromes. Addressing these conditions involves a multifaceted approach, where the most common antianginal medications alleviate symptoms by inducing coronary vasodilation and modifying the determinants of myocardial oxygen consumption, such as heart rate, myocardial wall stress, and ventricular contra ...

Nitrate Esters
In organic chemistry, a nitrate ester is an organic functional group with the formula , where R stands for any organyl group. They are the esters of nitric acid and alcohols. A well-known example is nitroglycerin, which is not a ''nitro'' compound, despite its name. : Synthesis and reactions Nitrate esters are typically prepared by condensation of nitric acid and the alcohol: For example, the simplest nitrate ester, methyl nitrate, is formed by reaction of methanol and nitric acid in the presence of sulfuric acid: :CH3OH + HNO3 -> CH3ONO2 + H2O Formation of a nitrate ester is called a nitrooxylation (less commonly, nitroxylation). Most commonly, "mixed acid" (nitric and sulfuric acids) are used, but in the 1980s production of the nitrocellulose with magnesium nitrate as a dehydrating agent was started in the US. In laboratory, phosphoric acid and phosphorus pentoxide or acetic acid and its anhydride may be used for the same purpose, or the nitroxylation can be conducted ...

BiDil
Hydralazine/isosorbide dinitrate, sold under the brand name Bidil, is a fixed-dose combination medication used to treat self-identified Black people with congestive heart failure. It is a combination of hydralazine hydrochloride (an arteriolar vasodilator) and isosorbide dinitrate (a nitrate vasodilator). The US Food and Drug Administration (FDA) approved medication to treat congestive heart failure in specifically self-identified Black patients. It provoked controversy as the first drug approved by the FDA marketed for a single racial-ethnic group. History From 1980 to 1985, Dr. Jay Cohn of the University of Minnesota led a clinical trial in collaboration with the US Veterans Administration called the Vasodilator-Heart Failure Trial (V-HeFT I) that tested whether the combination of isosorbide dinitrate and hydralazine increased survival in patients with heart failure. The results were promising and a follow-up study, V-HeFT II, tested the novel combination against enalapri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Approved Drug Products With Therapeutic Equivalence Evaluations
Approved Drug Products with Therapeutic Equivalence Evaluations, commonly known as the Orange Book, is a publication produced by the United States Food and Drug Administration (FDA), as required by the Drug Price and Competition Act (Hatch-Waxman Act). The Hatch-Waxman Act was created to '"strike a balance between two competing policy interests: # inducing pioneering research and development of new drugs and # enabling competitors to bring low-cost, generic copies of those drugs to market'". The Orange Book identifies drug products approved on the basis of safety and effectiveness by the Food and Drug Administration (FDA) under the Federal Food, Drug, and Cosmetic Act.

Cyclic Guanosine Monophosphate
Cyclic guanosine monophosphate (cGMP) is a cyclic nucleotide derived from guanosine triphosphate (GTP). cGMP acts as a second messenger much like cyclic AMP. Its most likely mechanism of action is activation of intracellular protein kinases in response to the binding of membrane-impermeable peptide hormones to the external cell surface. Through protein kinases activation, cGMP can relax smooth muscle. cGMP concentration in urine can be measured for kidney function and diabetes detection. History Cyclic guanosine monophosphate (cGMP) research began after cGMP and cyclic adenosine monophosphate (cAMP) were identified as cellular components and potentially involved with cellular regulation. Upon the synthesis of cGMP in 1960, progress rapidly spread in the understanding of regulation and effects of cGMP. Earl W. Sutherland received the 1971 Nobel Prize in Medicine for his work with cAMP and secondary messengers. This award sparked extensive research into cAMP, while cGMP ...

Guanylate Cyclase
Guanylate cyclase (EC 4.6.1.2, also known as guanyl cyclase, guanylyl cyclase, or GC; systematic name GTP diphosphate-lyase (cyclizing; 3′,5′-cyclic-GMP-forming)) is a lyase enzyme that converts guanosine triphosphate (GTP) to cyclic guanosine monophosphate (cGMP) and pyrophosphate: : GTP = 3′,5′-cyclic GMP + diphosphate It is often part of the G protein signaling cascade that is activated by low intracellular calcium levels and inhibited by high intracellular calcium levels. In response to calcium levels, guanylate cyclase synthesizes cGMP from GTP. cGMP keeps cGMP-gated channels open, allowing for the entry of calcium into the cell. Like cAMP, cGMP is an important second messenger that internalizes the message carried by intercellular messengers such as peptide hormones and nitric oxide and can also function as an autocrine signal. Depending on cell type, it can drive adaptive/developmental changes requiring protein synthesis. In smooth muscle, cGMP is the signal ...
