Estradiol valerate CAS: 979-32-8
Upon ingestion, regardless of the route of administration, estradiol valerate behaves as a prodrug, being cleaved by esterases in blood plasma and the liver into 17β-estradiol and valeric acid. However, compared to estradiol itself, estradiol valerate is absorbed more slowly and possesses a longer duration, especially when given in an oil solution via intramuscular injection (in which it acts as a depot). As a result, it can be administered less frequently.
A single intramuscular injection of 4mg estradiol valerate results in maximal plasma levels of estradiol of about 390 pg/mL within three days of administration, with levels declining to 100 pg/mL by 12–13 days. A study of high-dose combined administration of 40mg estradiol valerate and 250mg hydroxyprogesterone caproate in women once weekly for six months (described as a “pseudopregnancy” regimen) found that serum levels of estradiol increased from 27.8–34.8 pg/mL to 3028–3226 pg/mL after three months and to 2491–2552 pg/mL after six months of treatment.
