Angiotensin II human (Angiotensin II) TFA is a vasoconstrictor and a major bioactive peptide of the renin/angiotensin system. Angiotensin II human TFA plays a central role in regulating human blood pressure, which is mainly mediated by interactions between Angiotensin II and the G-protein-coupled receptors (GPCRs) Angiotensin II type 1 receptor (AT1R) and Angiotensin II type 2 receptor (AT2R). Angiotensin II human TFA stimulates sympathetic nervous stimulation, increases aldosterone biosynthesis and renal actions .
