However, clinical data show a slight beneficial effect of the drug on the ER-negative tumors, which gives grounds for assuming the existence of other mechanisms of action. Details
It is a recognized fact that tamoxifen has estrogen-like effect on a number of body systems, including endometrium, bone, and blood lipids.
After oral alpha pharma nolvadex rapidly absorbed, and maximum serum concentrations achieved within 4-7 hours.
Stable concentrations (approximately 300 ng / ml) were achieved after four weeks of treatment with a daily 40 mg dose of reception. The drug binds well to serum albumin (> 99%). As a result of metabolism in the process of hydroxylation and conjugation demethylation, formation takes place of several metabolites that are indicators pharmacological profile similar to the starting chemical compound, thus, contributes to the therapeutic effect. Isolation occurs mainly via feces. The half-life for the drug itself has been set at about seven days, while for the X-desmetiltamoksifena, the main circulating metabolite of 14 days.

Research in the field of reproductive toxicology, conducted with the participation of rats, rabbits and monkeys have shown no teratogenic potential.
In individuals rodents studied for fetal reproductive tract development, tamoxifen was associated with changes similar to those that are caused by exposure to estradiol, ethinyl estradiol, clomiphene and dietilstilbastrola (DES). Although the clinical correlation of these changes is unknown, some of them (especially vaginal adenosis), similar to that observed in young women who were exposed to DES in utero and in 1 of 1,000 cases of clear risk of occurrence of cancer of the vagina or cervix. Only a small number of pregnant women exposed to tamoxifen. In these cases, there are no reports that such exposure is the cause of the subsequent occurrence of vaginal adenosis or clear-vaginal or cervical cancer in young women exposed to tamoxifen.

When applied in combination with Nolvadex cytotoxic agents have an increased risk of thromboembolic events.
In connection with the treatment of drug Nolvadex noted an increased incidence of endometrial changes including hyperplasia, polyps and cancer. The frequency and pattern of this increase suggest that the underlying mechanism of the estrogen-related properties of Nolvadex. All earlier decision or when to take nolvadex patients in which there is abnormal vaginal bleeding, should be subject to the timely examination. Details
Tamoxifen did not show itself as a mutagenic agent in a series carried out in vitro and in vivo tests for mutagenicity. Tamoxifen provided genotoxic effect at the time of some in vitro experiments and tests for genotoxicity in vivo in rodents. During long-term studies were established facts gonadal tumors in mice and liver tumors in rats receiving tamoxifen. Clinical correlation of this data has not been established.
In clinical studies carried out after the treatment of patients with breast cancer with tamoxifen, it has been a number of second primary tumors arising in other than in the opposite enometrii and chest areas. A causal relationship has not been established, and the clinical significance of these observations remains unclear.
Lactation: Data on the allocation of Nolvadex into breast milk in the absence of women, therefore its use during lactation is not recommended. The decision to terminate or feeding, or the drug Nolvadex, must proceed from the importance of its application to the mother.

The use of Nolvadex is associated with changes in liver enzyme levels, and in rare cases, more serious disorders, including fatty liver, cholestasis and hepatitis.
Of the advantages Nolvadex increases the production of its own testosterone, reduces the amount of estrogens in the body.
