Pharmacokinetics
Taken internally levonorgestrel is rapidly and completely absorbed; its absolute bioavailability is close to 90%. Levonorgeetrel binds to serum albumin and binding globulin sex steroids (SHBG). Relative distribution (free, bound to albumin, linked to GTN) GTN is dependent on the concentration in the blood serum. Only about 2.5% of levonorgestrel serum in free form, while 47.5% and 50% bound to SHBG and albumin, respectively. The mean volume of distribution of levonorgestrel is about 137 L, and the rate of metabolic clearance of serum – about 5.7 l / h. The terminal half-life of levonorgestrel in serum after a single reception is within 14-20 hours. Lsvonorgsstrel as metabolites released in about equal proportions with urine and feces. Metabolites have weak or no pharmacological activity have generally shu. The main metabolite in urine – tetragidronorgestrel, which accounts for 10% of the radioactivity was detected in urine after administration of radiolabeled levonorgestrel with.
Approximately 0.1% of the dose received by the mother of levonorgestrel can pass through breast milk to the baby.

Dosage and administration
Mirena is inserted into the uterine cavity and is effective for five years. Lsvonorgesgrela release rate in vivo in the beginning is about 20 micrograms per day and after five years reduced to about 11 micrograms per day. The average release rate of levonorgestrel – about 14 micrograms per day for up to five years. MIRENA may be used in women receiving hormone replacement therapy, in combination with oral estrogen or tranedermalnymi preparations containing no progestogen.
When properly installed, Mirena, carried out in accordance with the instructions for use, the Pearl index (an indicator of the number of pregnancies in 100 women using a contraceptive during the year) is approximately 0.1% per year. 11ri expulsion or perforation Pearl Index may increase.
Instructions on the use of IUDs and handling of

The number of women with prolonged (more than eight days), bleeding is reduced from 20 to 3% in the first three months of use of Mirena. In clinical studies, it sustanon 250 for sale has been found that in the first year of Mirena 17% of women had amenorrhea duration of at least three months. When MIRENA is used in combination with estrogen replacement therapy in the first months of treatment in the majority of women in the peri- and post-menopausal observed spotting and irregular bleeding. In the future, their frequency decreases, and approximately 40% of women treated with this therapy in the last three months of the first year of treatment of bleeding in general disappear.Changes in the nature of bleeding are more common in the perimenopausal period than in postmenopausal.
