Description
Curator's Comment: description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/23811571, http://www.boryung.co.kr/eng/product/mainProduct.do

Fimasartan is a angiotensin II receptor antagonist which was developed in Korea for the treatment of hypertension. The drug is available in different forms: Kanarb, Dukarb (in combination with Amlodipine), Tuvero (in combination with Rosuvastatin). Fimasartan was tested to be effective in Mexican and Russian population and now is being tested in the USA.

Sample Use Guides

Fimasartan is taken as a single oral dose of 60-mg tablet or a single 30-mg intravenous (IV) infusion.
Route of Administration: Other
Rabbit thoracic aorta cells were incubated with different concentrations of fimasartan ((0.1, 1, 10 nM). At those concentrations fimasartan caused nonparallel rightward shifts in the concentration–contractile response curve to Ang II with a significant reduction in the maximal contractile response to 96.6, 47 and 18%, respectively.
