Source-derived summary

Estradiol/progesterone (E2/P4), sold under the brand name Bijuva among others, is a combined estrogen and progestogen medication which is used in the treatment of menopausal symptoms in postmenopausal women. It contains estradiol, an estrogen, and progesterone, a progestogen, and is available in both oral and intramuscular formulations. E2/P4 differs from other estrogen–progestogen formulations in that the sex-hormonal agents used are bioidentical.

Estradiol/progesterone is an oral combination of estradiol (E2), an estrogen, and progesterone (P4), a progestogen, which was developed by TherapeuticsMD and is approved in the United States for the treatment of menopausal symptoms in women. It is also under development for the treatment of endometrial hyperplasia in women. The medication contains 2 mg solubilized E2 and 200 mg P4 in each gelatin capsule. It is the first combination of E2 and P4 in oral capsule form that has been developed for clinical use. Bijuva is currently in phase III clinical trials for endometrial hyperplasia. The medication was approved by the Food and Drug Administration for the treatment of menopausal symptoms in October 2018. It is available as a generic medication.

Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as pharmaceutical combination. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jan 24, 2026. The linked authority identifier is Q28209424. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2018.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
