ATC code C09 Agents acting on the renin–angiotensin system is a therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System, a system of alphanumeric codes developed by the World Health Organization (WHO) for the classification of drugs and other medical products.
Irbesartan, sold under the brand name Aprovel among others, is a medication used to treat high blood pressure, heart failure, and diabetic kidney disease. [5] It is a reasonable initial treatment for high blood pressure. [5] It is taken by mouth. [5] Versions are available as the combination irbesartan/hydrochlorothiazide. [5] [6] [7] [8]
Angiotensin-converting-enzyme inhibitors (ACE inhibitors) are a class of medication used primarily for the treatment of high blood pressure and heart failure. [1] [2] This class of medicine works by causing relaxation of blood vessels as well as a decrease in blood volume, which leads to lower blood pressure and decreased oxygen demand from the heart.
Irbesartan was developed by Sanofi Research and is longer acting than valsartan and losartan and it has an imidazolinone ring where a carbonyl group functions as a hydrogen bond acceptor instead of the hydroxymethyl group in losartan. Irbesartan is a non-competitive inhibitor. [4]
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.
[citation needed] More recently, they have been used for the treatment of heart failure in patients intolerant of ACE inhibitor therapy, in particular candesartan. Irbesartan and losartan have trial data showing benefit in hypertensive patients with type 2 diabetes , [ citation needed ] and may delay the progression of diabetic nephropathy .
Direct thrombin inhibitors bind to the active sites of free or clot-bound thrombin to inhibit its effects. Dabigatran etexilate is a common example which has a rapid onset of action. [ 40 ] Whereas direct factor Xa inhibitors including apixaban and rivaroxaban directly bind to clotting factor Xa to block its activity, thus inhibiting thrombin ...
Class of medications that are competitive antagonists that block the receptor sites for the endogenous catecholamines epinephrine (adrenaline) and norepinephrine (noradrenaline) on adrenergic beta receptors, of the sympathetic nervous system.
