In a double-blind crossover study, patients were given either a placebo or tamoxifen (10 mg orally twice daily) for one month, in random order. Seven out of ten patients saw a reduction in gynecomastia size with tamoxifen (P < 0.005), and the overall reduction for the group was statistically significant (P < 0.01). [ 39 ]
Oral exemestane 25 mg/day for 2–3 years of adjuvant therapy was generally more effective than 5 years of continuous adjuvant tamoxifen in the treatment of postmenopausal women with early-stage estrogen receptor-positive/unknown receptor status breast in a large well-designed [citation needed] trial. Preliminary data from the open-label TEAM ...
Tamoxifen is a pure antiestrogenic trans-isomer and has differential actions at estrogen target tissues throughout the body. Tamoxifen is selectively antiestrogenic in the breast but estrogen-like in bones and endometrial cancer. [24] Tamoxifen undergo phase I metabolism in the liver by microsomal cytochrome P450 (CYP) enzymes.
One of the largest breast cancer prevention studies ever, [2] it included 22,000 women in 400 medical centers in the United States and Canada. [3] [4] [5] The study concluded that raloxifene caused fewer side-effects and less endometrial cancer than tamoxifen.
The study of comparative effectiveness research (CER) is composed of measures useful in determining the value of various treatment options to help patients make more informed decisions in their own care.
The study looked at medical records of nearly 3,500 patients with obesity who were prescribed semaglutide (Wegovy, Ozempic) or liraglutide, a medication to treat type 2 diabetes that can also lead ...
The median effective dose is the dose that produces a quantal effect (all or nothing) in 50% of the population that takes it (median referring to the 50% population base). [6] It is also sometimes abbreviated as the ED 50, meaning "effective dose for 50% of the population". The ED50 is commonly used as a measure of the reasonable expectancy of ...
N-Desmethyltamoxifen (developmental code name ICI-55,548) is a major metabolite of tamoxifen, a selective estrogen receptor modulator (SERM). [1] [2] N-Desmethyltamoxifen is further metabolized into endoxifen (4-hydroxy-N-desmethyltamoxifen), which is thought to be the major active form of tamoxifen in the body.
