It is a coenzyme that improves the body's metabolism and participates in the metabolism of fat, protein, sugar, nucleic acid and nucleotides in the body. It is also the main source of energy in the body. When energy is needed for absorption, secretion, muscle contraction and biochemical synthesis reactions, adenosine triphosphate is decomposed into adenosine diphosphate and phosphate groups, and energy is released at the same time. Animal experiments can inhibit the slow calcium ion influx of slow-reacting fibers, block or delay the forward conduction in the atrioventricular node reentry pathway, and large doses may also block or delay the forward and reverse conduction of the bypass pathway; in addition, it also has a short-term and strong effect of enhancing the vagus nerve, thereby terminating arrhythmias caused by atrioventricular node reentry and bypass reentry mechanisms.

Chronic toxicity: characterized by tubular nephropathy, with renal toxicity occurring at exposure levels of approximately 3 to 10 times the human therapeutic dose; Genotoxicity: mutagenicity was observed in the in vitro mouse lymphocytoma test, and chromosome aberrations were induced in the human peripheral blood lymphocyte test, but the results of the mouse micronucleus test and the Ames test were negative; Reproductive toxicity: no embryotoxicity or teratogenicity was observed in rat and rabbit tests, but embryotoxicity and fetal malformations occurred in pregnant rats when injected intravenously with high doses; Carcinogenicity: no carcinogenicity was observed in oral tests in mice and rats.
