Testolactone
Testolactone is a synthetic antineoplastic agent that is structurally distinct from the androgen steroid nucleus in possessing a six-membered lactone ring in place of the usual five-membered carbocyclic D-ring. Despite some similarity to testosterone, testolactone has no in vivo androgenic effect.
Toremifene Citrate
Toremifene citrate is an oral selective estrogen receptor modulator (SERM) which helps oppose the actions of estrogen in the body.
Raloxifene Hydrochloride
Raloxifene is used to prevent and treat osteoporosis (condition in which the bones become thin and weak and break easily) in women who have undergone menopause (change of life; end of menstrual periods).
DL-Aminoglutethimide
Aminoglutethimide is an adrenal steroid inhibitor. It works by blocking the production of a variety of hormones, including glucocorticoids, mineralocorticoids, estrogens, and androgens and is clinically used in the Treating Cushing syndrome and metastatic breast cancer. Aminoglutethimide is also used by body builders.
Formestane
Formestane is a synthetic steroidal substance with antineoplastic activity. Formestane binds irreversibly to and inhibits the enzyme aromatase, thereby blocking the conversion of cholesterol to pregnenolone and the peripheral aromatization of androgenic precursors into estrogens.
Letrazole (Femara / Formestane)
emara (letrozole) is a type II (non-steroidal) third generation aromatase inhibitor.
Anastrozole (Arimidex)
Anastrozole is also called Arimidex. It is a type of hormone therapy called an aromatase inhibitor. Anastrozoles treats breast cancer in women who have had their menopause.
Exemestane (Aromasin)
Exemestane is indicated for the adjuvant treatment of postmenopausal women with estrogen-receptor positive early breast cancer who have received two to three years of tamoxifen and are switched to it for completion of a total of five consecutive years of adjuvant hormonal therapy.
Clomiphene Citrate (Clomid)
Clomifene or clomiphene (trademarked as Androxal, Clomid and Omifin, citrate salt Serophene) is a selective estrogen receptor modulator (SERM) that has become the most widely prescribed drug for ovulation induction to reverse anovulation or oligoovulation.
Tamoxifen Citrate (Nolvadex)
Nolvadex (tamoxifen citrate) is very comparable to Clomid, behaves in the same manner in all tissues, and is a mixed estrogen agonist/antagonist of the same type as Clomid.
