Abstract
A nasal spray formulation for use in female contraception or in the treatment of benign gynecological disorders is described. The nasal preparation is comprised of a GnRH compound and an estrogenic compound in the form of a water-soluble complex with a water-soluble cyclodextrin. The preparation effectively suppresses ovarian estrogen and progesterone production, and prevents signs and symptoms of estrogen deficiency, without a significant increase in the risk of endometrial hyperplasia.
