A naturally occurring tricarboxylic acid widely used in pharmaceutical formulations as an acidulant, buffering agent, antioxidant, and chelating agent. It is also used as a urinary alkalinizer in oral solutions to dissolve uric acid and cystine kidney stones. As a component of anticoagulant solutions, it binds calcium to prevent blood clotting during storage.

Mécanisme d'action

Selectively blocks angiotensin II type 1 (AT1) receptors, preventing the vasoconstrictive and aldosterone-secreting effects of angiotensin II. This results in vasodilation, reduced sodium retention, and decreased blood pressure.
