Azilsartan medoxomil is a carboxylic ester obtained by formal condensation of the carboxy group of azilsartan with the hydroxy group of 4-(hydroxymethyl)-5-methyl-1,3-dioxol-2-one. A prodrug for azilsartan, it is used for treatment of hypertension. It has a role as a prodrug, an angiotensin receptor antagonist and an antihypertensive agent.
Azilsartan medoxomil is a useful and attractive new option for lowering BP in patients with essential hypertension, particularly for those not able to tolerate other antihypertensive drugs. Further studies are required to evaluate the effects of azilsartan medoxomil on cardiovascular morbidity and mortality.
Azilsartan medoxomil was mostly absorbed from the jejunum, duodenum, and ileum and was poorly absorbed from the stomach and colon. Non-clinical data suggest that lymphatic absorption is not important for this compound. Oral absorption and bioavailability of azilsartan medoxomil were assessed in rats, dogs and monkeys.
Azilsartan medoxomil(TAK 491) is an orally administered angiotensin II receptor type 1 antagonist with IC50 of 0.62 nM, which used in the treatment of adults with essential hypertension.
The invention relates to the field of medicines and in particular relates to a synthesis method for azilsartan medoxomil or salt thereof, an intermediate of the azilsartan medoxomil or the salt thereof and a synthesis method for the intermediate. According to the novel method for the azilsartan medoxomil or the salt thereof, the problems of low synthesized azilsartan medoxomil yield and large.
During the process development of olmesartan medoxomil, three process-related impurities were observed along with the final API. These impurities were identified as isopropyl olmesartan (12), dimedoxomil olmesartan (19), dibiphenyl olmesartan (17). The present work describes the synthesis and characterization of all these three impurities.
Abstract. This paper provides a description of an alternative, novel and commercially viable process which has been developed for the preparation of Azilsartan, a pro-drug of Azilsartan medoxomil, an angiotensin II receptor blocker.
Azilsartan medoxomil is hydrolyzed to Azilsartan, the. Chapter-4 119 active metabolite, in the gastrointestinal tract during absorption. Azilsartan medoxomil is. synthesis (2-3). An extensive literature survey reveals that, few HPLC methods have been reported, for the quantification of AZL in pharmaceutical dosage forms. One HPLC.
Indications, dose, contra-indications, side-effects, interactions, cautions, warnings and other safety information for AZILSARTAN MEDOXOMIL.
The present work describes the novel synthesis of azilsartan medoxomil from amidoxime methyl ester. The present work also describes the improved synthesis of amidoxime methyl ester and azilsartan.
Azilsartan medoxomil is an orally administered prodrug that is rapidly converted by esterases during absorption to the active moiety, azilsartan. Azilsartan blocks the vasoconstrictor and aldosterone-secreting effects of angiotensin II by selectively blocking the binding of angiotensin II to the AT1 receptor in many tissues, such as vascular smooth muscle and the adrenal gland.
