  • Follicular phase estrogen or progestin with physiologic estrogen/progestin luteal phase replacement drug delivery system
    Patent number: 4292315
    Abstract: A method, formulation, and steroid drug delivery system for the administration of sex steroids for menstrual cycle regulation is disclosed. The invention is useful in clinical applications for pregnancy spacing and treatment of menstrual dysfunction. Progestin and estrogen are administered in a treatment cycle mimicking sex steroid hormones in the normal menstrual cycle. The steroid treatment cycle is divided into arbitrary and discrete follicular and luteal phase segments beginning with the onset of menstruation. In the early segment of the follicular phase no exogenous steroid is administered. Depending on the clinical and/or physiologic situation of a patient, unopposed progestin or estrogen is then administered.
