Progesterone showdown: are two injections equally effective?
NCT ID NCT07495007
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a new injectable progesterone (Prontogest) works the same in the body as the standard progesterone injection. Twenty-six healthy postmenopausal women received single doses of each in a randomized order. The goal was to check if the two formulations are bioequivalent, meaning they produce similar drug levels in the blood.
