Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, and in particular relates to a preparation method of azilsartan medoxomil potassium salt dispersible tablets. Background technique [0002] Azilsartan medoxomil was developed by Takeda, Japan. A prodrug of azilsartan that is hydrolyzed to azilsartan during absorption from the gastrointestinal tract. It was approved for marketing by FDA on February 22, 2011. The trade name is Edarbi, and the specifications are 40mg and 80mg. In April 2012, Azilsartan was launched in Japan, trade name: Azilva, specification: 20mg, 40mg. Azilsartan medoxomil is a selective AT1 subtype angiotensin II receptor antagonist. Azilsartan selectively blocks the binding of angiotensin II to the AT1 receptor (the affinity of azilsartan to the AT1 receptor is more than 10,000 times higher than that of the AT2 receptor), thereby blocking the vasoconstriction caused by angiotensin II , Aldosterone secretion and oth...
