What is Endometrin?

Endometrin is a prescription medicine that is used in in vitro fertilization. Endometrin may be given to you for other reasons.

Description

ENDOMETRIN (progesterone) Vaginal Insert contains micronized progesterone. ENDOMETRIN is supplied with polyethylene vaginal applicators.

The active ingredient, progesterone, is present in 100 mg amount along with other excipients. The chemical name for progesterone is pregn-4-ene-3,20-dione. It has an empirical formula of C21H30O2 and a molecular weight of 314.5. Progesterone exists in two polymorphic forms. The form used in ENDOMETRIN, the alpha-form, has a melting point of 127-131°C.

The structural formula is:

Each ENDOMETRIN Vaginal Insert delivers 100 mg of progesterone in a base containing lactose monohydrate, polyvinylpyrrolidone, adipic acid, sodium bicarbonate, sodium lauryl sulfate, magnesium stearate, pregelatinized starch, and colloidal silicon dioxide.

Mechanism of Action

Progesterone is a naturally occurring steroid that is secreted by the ovary, placenta, and adrenal gland. In the presence of adequate estrogen, progesterone transforms a proliferative endometrium into a secretory endometrium. Progesterone is necessary to increase endometrial receptivity for implantation of an embryo. Once an embryo is implanted, progesterone acts to maintain a pregnancy.
