Levonorgestrel is rapidly absorbed (time for complete absorption of less than 4 hours). No first-pass effect through the liver. The bioavailability buy anavar of almost one hundred percent. Most levonorgestrel binds to plasma proteins, mainly albumin and globulins, sex steroid binding .
Achieve maximum concentration in the plasma of levonorgestrel (TSmax) was 2 h.Levonorgestrel half-life (T1 / 2) ranges from 8 to 30 hours (mean 16 hours). Levonorgestrel is excreted through the kidneys – 60% and intestine – 40% as metabolites (glucuronide and sulfate conjugates).Ethinyl estradiol Ethinyl estradiol is absorbed rapidly and almost completely. Ethinyl estradiol is inherent in first pass effect through the liver, TSmax is 1.5 hours. After oral administration the bioavailability of about 38-48%. Ethinylestradiol almost completely bound to plasma proteins, mainly albumin. Ethinylestradiol undergoes first-pass metabolism in the gut wall and liver. Active substances are metabolized in the liver. As ethinyl estradiol and metabolites (OH-2 and 2-ethinyl-methoxy-ethinyl estradiol) are allocated as conjugates (glucuronides and sulfates) buy anavar in the bile and undergo enterohepatic recirculation. The half-life 26 ± 6.8 hours. About 40% excreted through the kidneys and about 60% through the intestines. Both components (levonorgestrel and ethinyl estradiol) are excreted in breast milk.
