1.

Ethinyl Estradiol

A semisynthetic alkylated ESTRADIOL with a 17-alpha-ethinyl substitution. It has high estrogenic potency when administered orally, and is often used as the estrogenic component in ORAL CONTRACEPTIVES. [from MeSH]

MedGen UID:
41887
Concept ID:
C0015011
Hormone; Organic Chemical; Pharmacologic Substance
2.

Drospirenone

A synthetic spironolactone analogue and progestin with progestational and anti-mineralocorticoid activity. Drospirenone binds to the progesterone receptor, the resulting complex becomes activated and binds to specific sites on DNA. This results in a suppression of LH activity and an inhibition of ovulation as well as an alteration in the cervical mucus and endometrium. This leads to an increased difficulty of sperm entry into the uterus and implantation. This drug is used in oral contraceptives. [from NCI]

Concept ID:

Organic Chemical; Pharmacologic Substance
3.

Estradiol

A steroid sex hormone vital to the maintenance of fertility and secondary sexual characteristics in females. Typically esterified, estradiol derivatives are formulated for oral or parenteral administration. As the primary, most potent estrogen hormone produced by the ovaries, estradiol binds to and activates specific nuclear receptors. Estradiol exhibits mild anabolic and metabolic properties, and increases blood coagulability. [from NCI]

4.

Premenstrual dysphoric disorder

A condition in which a woman suffers from severe depression, irritability, and tension before MENSTRUATION. Premenstrual dysphoric disorder (PMDD) may involve a wide range of physical or emotional symptoms, which are more severe and debilitating than those seen with premenstrual syndrome (PMS), and which include at least one mood-related symptom. Symptoms usually stop when, or shortly after, menstruation begins. [from MeSH]

MedGen UID:

Concept ID:
C0520676
Mental or Behavioral Dysfunction
5.

Drospirenone + ethinyl estradiol

A combination of two steroid sex hormones, the estrogen ethinyl estradiol and a progestin drospirenone, used for contraceptive purposes. The combination of ethinyl estradiol with drospirenone suppresses the hypothalamic-pituitary system, leading to an inhibition of the release of gonadotropin hormones follicle stimulating hormone (FSH) and luteinizing hormone (LH). The inhibition of FSH release suppresses the development of ovarian follicle. The decreased release of LH inhibits ovulation. In addition, thickening of the cervical mucus and the endometrium is promoted, thereby altering the endometrium in such a way as to discourage implantation. [from NCI]
