Nitrovasodilator. A nitrovasodilator is a pharmaceutical agent that causes vasodilation (widening of blood vessels) by donation of nitric oxide (NO), [1] and is mostly used for the treatment and prevention of angina pectoris. This group of drugs includes nitrates (esters of nitric acid), which are reduced to NO in the body, as well as some ...
Nitric oxide (nitrogen monoxide) is a molecule and chemical compound with chemical formula of N O. In mammals including humans, nitric oxide is a signaling molecule involved in several physiological and pathological processes. [1] It is a powerful vasodilator with a half-life of a few seconds in the blood.
Nitroglycerin (NG) (alternative spelling of nitroglycerine), also known as trinitroglycerol (TNG), nitro, glyceryl trinitrate (GTN), or 1,2,3-trinitroxypropane, is a dense, colorless or pale yellow, oily, explosive liquid most commonly produced by nitrating glycerol with white fuming nitric acid under conditions appropriate to the formation of the nitric acid ester.
The CCS grading system for angina is, in part, used to evaluate fitness to fly by the British Cardiovascular Society.They recommend no action by class I and II patients with stable angina, class III should consider mobility assistance from airport staff and in-flight supplemental oxygen therapy, and that class IV patients should ideally defer their travel plans or travel with a medical ...

Renal tubular acidosis (RTA) is a medical condition that involves an accumulation of acid in the body due to a failure of the kidneys to appropriately acidify the urine. [1] In renal physiology, when blood is filtered by the kidney, the filtrate passes through the tubules of the nephron, allowing for exchange of salts, acid equivalents, and other solutes before it drains into the bladder as urine.
Ranolazine, sold under the brand name Ranexa among others, is a medication used to treat heart related chest pain. [5] Typically it is used together with other medications when those are insufficient. [5][6] Therapeutic benefits appear smaller in females than males. [5] It is taken by mouth.
The interpretation of urinalysis takes into account the results of physical, chemical and microscopic examination and the person's overall condition. Urine test results should always be interpreted using the reference range provided by the laboratory that performed the test, or using information provided by the test strip/device manufacturer. [136]
