Tác dụng
Description: Mechanism of Action: Arginine is an essential amino acid that stimulates the pituitary release of human growth hormone (hGH) and prolactin that may be used, instead of, or in addition to other diagnostic tests. It is also an important constituent for the storage and excretion of ammonia in the urea cycle and an acidifying agent in cases of severe metabolic alkalosis. Pharmacokinetics: Absorption: Time to peak plasma concentration: Approx 20-30 minutes. Distribution: Enters breast milk. Volume of distribution: Approx 33 L/kg. Metabolism: Extensively metabolised in the liver and intestines via hydrolytic cleavage by the guanidine group to ornithine and urea. Excretion: Via urine (16% during the 1st 90 minutes). Elimination half-life: 42 ± 2 minutes.
