Pharmacological properties
The active ingredient amoxifen is an antiestrogen non-steroidal substance that also has a weak estrogenic property. Hisantitumor effect is based on the ability to block estrogen receptors.
Tamoxifen and its metabolites compete with estradiol instead of binding to cytoplasmic estrogen receptors in breast, vaginal, uterine, anterior pituitary, and neoplasms with a high concentration of estrogen receptors. Tamoxifen does not stimulate the production of DNA in the nucleus, but inhibits cell division, which contributes to the regression of pathological cells and their destruction.
Pharmacokinetics
After taking tamoxifen is well absorbed. The highest concentration in the blood occurs approximately 4-7 hours after a single dose. The equilibrium level of this active element in the serum, as a rule, is reached after 3 weeks of use. It goes through the process of metabolism in the liver with the formation of several substances. Excretion from the body has a two-stage nature with an initial half-life of 7 to 13 hours, followed by a terminal half-life of 7 days. This substance is excreted mainly in the form of conjugates, with feces and in small amounts with urine.

Reviews about "Tamoxifen Ebewe"
There are very few reviews of such a medicine on medical websites, and this is due to the fact that oncological diseases do not occur in people too often, especially since such medicines are not always prescribed for them.
From the information on a few reviews, we can conclude that Tamoxifen-Ebewe was not always effective, but only in about half of the cases of its use. Patients indicate a good tolerability of this treatment. In many of them, the growth of a pathological neoplasm during therapywas suspended, others did not have this effect, and these people were prescribed other treatment.
