Description

Lasofoxifene: structure in first source [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]

lasofoxifene : A member of the class of tetralins that is 5,6,7,8-tetrahydronaphthalen-2-ol in which the hydrogens at positions 5 and 6 are replaced by 4-[2-(pyrrolidin-1-yl)ethoxy]phenyl and phenyl groups, respectively (the 5R,6S-stereoisomer). It is a selective estrogen receptor modulator indicated for the prevention and treatment of osteoporosis in post-menopausal women.

Treatment

ExcerptReference
"Lasofoxifene treatment resulted in a small increase in endometrial thickness versus placebo (least-squares mean change from baseline 1.19 mm [P = 0.001], 1.43 mm [P < 0.001], and -0.72 mm for 0.25 mg/day lasofoxifene, 0.5 mg/day lasofoxifene, and placebo)."( Colgan, T; Cummings, S; Goldstein, SR; Johnson, M; Krpan, D; Neven, P; Proulx, J; Runowicz, CD; Sriram, U; Thompson, D; Thompson, J, 2011)
