Description:

Progestins are primarily produced endogenously by the corpus luteum. They transform proliferative endometrium to secretory endometrium, enhance myometrium hypertrophy and inhibit spontaneous uterine contraction. Progestins have a dose-dependent inhibitory effect on the secretion of pituitary gonadotropins and also have some degree of estrogenic, anabolic and androgenic activity.

Altrenogest (or allyltrenbolone) is a synthetic trienic C21 steroidal progestomimetic, belonging to the 19-nor-testosterone series. It is an orally active (pro)gestagen. Like all steroids, altrenogest acts by its liposolubility by penetrating the target cells where it binds to specific receptors.

Applications:

The pharmacodynamic activity of altrenogest has been demonstrated in a number of animal models. The most important effects are the progestomimetic and anti-gonadotrophic effects. Altrenogest also has weak oestrogenic, anabolic and androgenic effects, but has no corticoid or anti-inflammatory effects.

Altrenogest is indicated (labeled) to suppress estrus in mares to allow a more predictable occurrence of estrus following withdrawal of the drug. It is used clinically to assist mares to establish normal cycles during the transitional period from anestrus to the normal breeding season often in conjunction with an artificial photoperiod. It is more effective in assisting in pregnancy attainment later in the transition period. One group of authors (Squires et al. 1983) suggest selecting mares with considerable follicular activity (mares with one or more follicles 20 mm or greater in size) for treatment during the transitional phase. Mares that have been in estrus for 10 days or more and have active ovaries are also considered to be excellent candidates for progestin treatment.

Directions& Explanation

Pregnenolone is a chemical that is found in our bodies. It can also be made in a laboratory. People use it for medicine.

Pregnenolone is used for fatigue and increasing energy; Alzheimer's disease and enhancing memory; trauma and injuries; as well as stress and improving immunity.

It is also is used for skin disorders including psoriasis and scleroderma.

Women use pregnenolone for lumpy breasts (fibrocystic breast disease), a disorder of the lining of the uterus (endometriosis), symptoms of menopause, and premenstrual syndrome (PMS).

Some people use pregnenolone for slowing or reversing aging, arthritis, and depression. It is also used for strengthening the heart, allergic reactions, "detoxification," lupus, multiple sclerosis (MS), prostate problems, and seizures.

Because the body uses pregnenolone to make many hormones, pregnenolone was studied for stress, fatigue, and arthritis in the 1940s before lab-made hormones became available.

Pregnenolone is a natural hormone that cannot be patented. Back in the 1940's, when researchers started experimenting with it, they realized that it could be helpful for people under stress and it could increase energy in those who were fatigued. However, about the same time, cortisol, another closely related hormone, was discovered. Cortisol stole the limelight. When cortisol was given to individuals with rheumatoid arthritis, there were outstanding short-term improvements. Photographs of these remarkable recoveries were circulated and the medical community was impressed. Scientists basically put pregnenolone aside to focus on cortisol. The structure of cortisol was altered to make similar molecules such as dexamethasone and prednisone, much more powerful steroids. Dexamethasone and other similar corticosteroids could be patented, and thus a pharmaceutical company could make a lot of money. Pregnenolone has stayed in relative obscurity since the 1940's, with only rare mentions in the medical literature. There have been few studies published on pregnenolone in recent years, and only a couple involve human subjects.
