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]
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.
Drug treatment options are limited, as many antihypertensives may negatively affect the fetus. ACE inhibitors, angiotensin receptor blockers, and direct renin inhibitors are contraindicated in pregnancy as they are teratogenic. Methyldopa, hydralazine, nifedipine, and labetalol are most commonly used for severe pregnancy hypertension. [7]
[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 .
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]
Use during pregnancy is believed to result in harm to the baby. [5] It is in the angiotensin-converting-enzyme (ACE) inhibitor family of medications. [5] Enalapril was patented in 1978, and came into medical use in 1984. [7] It is on the World Health Organization's List of Essential Medicines. [8]
Therefore, ACE indirectly increases blood pressure by causing blood vessels to constrict. ACE inhibitors are widely used as pharmaceutical drugs for treatment of cardiovascular diseases. [5] Other lesser known functions of ACE are degradation of bradykinin, [6] substance P [7] and amyloid beta-protein. [8]
