Clin Cancer Res. No association between the serum levels of tamoxifen and its metabolites and the SULT1A1 genotypes was demonstrated in this subgroup of postmenopausal women. Therapeutic duplication warnings are only returned when drugs within the same group exceed the recommended therapeutic duplication maximum. Hum Mol Genet. Limitations of the present study are that the correlations observed are weak and we have not had admittance to patient journals and do not know of any additional drug use. Pharmacol Rev. Drugs A to Z Print Share. However, we and others have observed that breast cancer patients often use several additional drugs that may interact with tamoxifen [ 49 — 52 ]. This does not necessarily mean no interactions exist. Avoid combinations; the risk of the interaction outweighs the benefit. Some mixtures of medications can lead to serious and even fatal consequences. Therefore, it is interesting that of the five tamoxifen metabolites examined, only the serum concentrations of 4OHNDtam was positively associated with the dhea with nolvadex

A total of drugs are known to interact with Nolvadex D. Explore Apps. Hot flashes have been suggested as a predictor of tamoxifen efficacy [ 26 ]. Always consult your healthcare provider to ensure the information displayed on this page applies to your personal circumstances. J Chromatogr A. Available for Android and iOS devices. Methods Patients From a study on tamoxifen metabolism in pre- and postmenopausal women adjuvantly treated with tamoxifen 20 mg daily, we included exclusively postmenopausal women in order to examine patients with stable estrogen and FSH levels [ 7 ]. Patients carrying functional CYP2D6 alleles been reported to have a higher incidence of hot flashes, higher levels of the active metabolites of tamoxifen, and better outcome during tamoxifen treatment [ 7 , 25 , 26 ]. The serum level of SHBG was 81 . Click on an option below to access. J Natl Cancer Inst. Usually avoid combinations; use it only under special circumstances.

Request Username Can't sign in? Figure 1. Highly clinically significant. This may suggest that estrogen levels during tamoxifen therapy may have limited importance. An alternative explanation is that tamoxifen and its nlovadex inhibit enzymes that are involved in the degradation of estrogens. Therapeutic duplication warnings No warnings were found for your selected drugs. Therefore, we hypothesized that these genotypes that are proposed predictors for response to tamoxifen influence estrogen metabolism and that correlations between serum tamoxifen and estrogen levels exist.
