Drospirenone: a novel progestin
Expert Opinion on Pharmacotherapy, 2007Drospirenone is a novel progestin available in combined oral contraceptives and menopausal hormonal therapy. Similar to its parent compound spirolactone, an analog of spironolactone, drospirenone has antimineralocorticoid and antiandrogenic activity.

On the mechanism of action of progestins
Acta Endocrinologica, 1981Abstract. The effect of two synthetic injectable progestins, norethisterone oenanthate3 (NET-e) and medroxyprogesterone acetate (MPA) upon the hypothalamic pituitary unit was evaluated in post-menopausal women (PMW) and in castrated individuals with androgen un-responsiveness in order to gain insight into their mechanism of gonadotrophin inhibition ...

Role of progestins in contraception
Acta Obstetricia et Gynecologica Scandinavica, 2005Progestins have been used for contraception for more than 30 years. The main goal was to develop a contraceptive method devoid of the metabolic or clinical side‐effects associated with the use of estrogens. The development of new contraceptive methods and formulations is time‐consuming and requires devotion, belief, and also strong economical basis. As

Progestins are a group of different compounds sharing the ability to induce secretory changes on a endometrium pretreated with estrogen, while they are different in some abilities, for example the interaction with receptors other than progestin receptor, as androgenic or mineralocorticoid receptor. Some progestins have antiandrogenic properties and are

Progesterone-Progestin Receptors
1974A correlation between binding to the progestin-specific uterine cytosol receptor and with well-defined facets of progesterone action was established. Structurally similar derivatives of norprogesterone and nortestosterone were compared. Binding was measured in vitro by determining their competitive effect on the progestin-tagged uterine cytosol ...

Progesterone exerts most of its actions through its specific receptors. However, synthetic progestins and progesterone itself may bind with other steroid receptors, thus producing a variety of effects. For instance, some nonsteroid derivatives produce virilizing effects by acting on testosterone receptors.

The Selectivity of a New Progestin
Acta Obstetricia et Gynecologica Scandinavica, 1990Norgestimate is a new progestin developed for use with ethinyl estradiol as a combination oral contraceptive. It binds to rabbit uterine progestational receptors and in the oral form stimulates a progestational endometrial effect in rabbits. Norgestimate also exerts a direct effect on target organs, stimulating the endometrium in rabbits when injected ...
