What is Endometrin (and what API is it)?
Endometrin is a brand name for vaginal estradiol (estradiol progesterone/estrogen therapy depending on country/indication wording) used as part of fertility treatment to support the uterine lining. The active pharmaceutical ingredient (API) in Endometrin is estradiol (administered intravaginally).
What exact API form do products like Endometrin use?
Endometrin products generally contain estradiol in a vaginal formulation (commonly as a tablet/insert form for intravaginal use). The specific strength (how many mg) and formulation details depend on the exact product presentation sold in a given market.
Why does “API” matter for searching replacements or generics?
When people ask for the “API for Endometrin,” they typically want to find:
- products that use the same active ingredient (estradiol), and
- the same route of administration (vaginal/intravaginal), since estradiol given by other routes is not a like-for-like replacement.
How to confirm the API for a specific Endometrin product you have
Because Endometrin naming and presentation can vary by country and packaging, the most reliable check is the label:
- “Active ingredient” / “Composition” section will list estradiol and its strength per unit.
If you tell me the country and the strength (mg) shown on your Endometrin box (or paste the label text), I can help you identify the matching API and how it maps to equivalent estradiol vaginal inserts/tablets.
