There is considerable confusion concerning the use of the term "progestin" in referring to progestational compounds. Such term is often restricted to progestational agents that are synthetic and excludes progesterone which is a natural compound. In 1930 when progesterone had not yet been isolated the term "progestin" was proposed for the name of this

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 ...

Classification and pharmacology of progestins
Maturitas, 2003Besides the natural progestin, progesterone, there are different classes of progestins, such as retroprogesterone (i.e. dydrogesterone), progesterone derivatives (i.e. medrogestone) 17alpha-hydroxyprogesterone derivatives (i.e. chlormadinone acetate, cyproterone acetate, medroxyprogesterone acetate, megestrol acetate), 19-norprogesterone derivatives (i.

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 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 Metabolic Influence of Progestins
1971Publisher Summary This chapter discusses the effects of progesterone and synthetic progestins. The metabolic effects of synthetic progestins can be related to their pharmacological uses, including the unwanted side effects of the oral contraceptive drug mixtures. The most completely described influence of the progestins is that exerted on protein and

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 ...
