Splet22. maj 2015 · The biological half-life cannot be determined as precisely as the physical half-life, and the dominance of either rate differs from one radionuclide to another. For many long-lived nuclides, such as 3 H, 14 C, 22 Na, 36 Cl, 60 Co, 137 Cs and 235 U, the much shorter biological half-life (10–70 d) is dominant . SpletPlasma half-life (T 1/2) is the time required for plasma concentration to diminish by 50%. After IV injection the decline in serum concentration occurs in two phases. The initial decline is rapid and attributed to drug distribution. This period of decline is regarded as distribution half-life (T 1/2α) and is applicable only to IV drugs.

SpletThe plasma half-life of insulin is 3-5 min. The principal pathway for the lowering of plasma insulin levels is receptor-mediated endocytosis of the insulin-receptor complex; a major site of this activity is in the liver,with the kidney as the second most important site.
