Estradiol, the active form of EHHB. Pharmacodynamics EHHB is an estradiol ester, or a prodrug of estradiol. As such, it is an estrogen, or an agonist of the estrogen receptors. EHHB is of about 40% higher molecular weight than estradiol due to the presence of its C17β cyclohexanecarboxylate ester. Because EHHB is a prodrug of estradiol, it is considered to be a natural and bioidentical form of estrogen. Pharmacokinetics A combination of EHHB and norgestrel as a combined injectable contraceptive reportedly has a duration of action of about 3 weeks.
