Diethylstilbestrol is a synthetic non-steroidal estrogen. It is used in the treatment of menopausal and postmenopausal disorders, prostate cancer and in the prevention of miscarriage or premature delivery in pregnant women prone to miscarriage or premature delivery. Diethylstilbestrol is a very potent full agonist of the estrogen receptors. At the cellular level, estrogens increase the synthesis of DNA, RNA, and various proteins in target tissues. Pituitary mass is also increased. Estrogens reduce the release of gonadotropin-releasing hormone from the hypothalamus, leading to a reduction in release of follicle-stimulating hormone and luteinizing hormone from the pituitary. Adverse effects are: breast pain or tenderness, enlargement of breasts, gynecomastia, peripheral edema and others. Estrogens may interfere with the effects of bromocriptine. Dosage adjustment may be needed. Concurrent use with estrogens may alter the metabolism and protein binding of the glucocorticoids, leading to decreased clearance, increased elimination half-life, and increased therapeutic and toxic effects of the glucocorticoids.

Imidocarb is a carbanilide derivative with antiprotozoal activity. It is usually administered as the dipropionate salt. Imidocarb is a drug sold under the brand name Imizol and is used to treat canine ehrlichiosis. wo mechanisms of action have been proposed: As the effect of imidocarb on Trypanosoma brucei is antagonized by excess polyamines, it is has been suggested that imidocarb interferes with their production and/or use. Imidocarb blocks the entry of inositol into erythrocytes containing Babesia, resulting in starvation of the parasite. It is generally accepted in that imidocarb has anticholinesterase activity.

Hemin (trade name Panhematin) is a protoporphyrin IX containing a ferric iron ion (heme B) with a chloride ligand, which is is indicated for the amelioration of recurrent attacks of acute intermittent porphyria temporally related to the menstrual cycle in susceptible women. Manifestations such as pain, hypertension, tachycardia, abnormal mental status and mild to progressive neurologic signs may be controlled in selected patients with this disorder. the therapy for the acute porphyrias is not curative. Heme acts to limit the hepatic and/or marrow synthesis of porphyrin. This action is likely due to the inhibition of δ-aminolevulinic acid synthetase, the enzyme which limits the rate of the porphyrin/heme biosynthetic pathway. The exact mechanism by which hematin produces symptomatic improvement in patients with acute episodes of the hepatic porphyrias has not been elucidated.

This compound belongs to the class of organic compounds known as androgens and derivatives. These are 3-hydroxylated C19 steroid hormones. They are known to favor the development of masculine characteristics. They also show profound effects on scalp and body hair in humans. The value of Δ5-diol as a radiation countermeasure is based mainly on its stimulation of production of white blood cells and platelets. Androstenediol used by the body to make testosterone and estrogen. There is some concern that androstenediol might increase the risk of coronary heart disease. There is also developing evidence that androstenediol might help prostate cancer cells grow. Taking androstenediol along with estrogen and testosterone pills might cause too much estrogen or testosterone in the body.
