FLUROGESTONE (9α-FLUORO-11β,17α-DIHYDROXYPROGESTERONE) is a steroidal progestin of the 17α-hydroxyprogesterone group that was never marketed. An acetate ester, flurogestone acetate, is used in veterinary medicine. It has progestational action higher than that of progesterone itself. It is intended for intravaginal use in sheep and goats to induce oestrus synchronisation. The proposed dosage is 1 sponge, impregnated with 30, 40 (for sheep) or 45 mg (for goats) flugestone acetate, which is to be removed after 12 to 14 days from ewes and after 17 to 21 days from goats. Flugestone acetate is not indicated for use in humans.

The compound believed to be principally responsible for the unpleasant odor sometimes produced during cooking of pork or bacon from boars has been isolated and identified as 5a-androst-16-en-3-one. It is the first mammalian pheromone to be identified. Androstenone is the active ingredient in a commercial products which were developed for farmers and breeders who need help determining the best fertilization time for sows and gilts. In humans, androstenone also has been suggested to be a pheromone. Excessive exposures may affect human health, as follows: Upper respiratory tract: Irritation, Dizziness, Drowsiness, Headache, Nausea; Skin: Redness.

Fluperolone (P-1742 or Methral) is a topical fluorinated prednisolone derivative exerting an anti-inflammatory activity. It demonstrated effectivity in the treatment of various dermatoses.

α-Asarone is a phytochemical compound with neuroprotective, anti-oxidative, anticonvulsive and cognitive enhancing action, isolated from the Chinese medicinal herb Acorus tatarinowii. Numerous clinical studies in China had indicated the effectiveness of α-asarone against respiratory disorders and epilepsy. Asarone tablets have been clinically used as bronchial asthma and bronchitis prescription drug in China. Unfortunately, toxic and genotoxic studies of a-asarone have indicated that this compound may pose a risk to human health, including embryotoxicity and maternal toxicity in rats, hepatotoxicity in rat-cultivated hepatocytes, and in vivo and in vitro genotoxic damage in mammalian cells.

Clostebol acetate (4-chloro-testosterone acetate), an anabolic androgenic agent used for fattening purposes in cattle breeding or applied topically in ophthalmological and dermatological treatments. The European Commission has prohibited its use since 1986.

Methadyl Acetate is a narcotic analgesic with a long onset and duration of action. Methadyl Acetate is primarily a mu-type opioid receptor agonist and the drug decreases a patient's opioid use by preventing opioid withdrawal. Levacetylmethadol, the enantiomer of Methadyl Acetate, was approved in 1993 by the U.S. Food and Drug Administration for use in the treatment of opioid dependence. In 2001, levacetylmethadol was removed from the U.S. market due to reports of life-threatening ventricular rhythm disorders.

Fluprednidene (used in a form of fluprednidene 21-acetate) is a glucocorticoid developed for the treatment of inflammatory skin diseases. The drug is marketed under the name Decoderm in Europe.

Chloroprednisone acetate is the 21-acetate ester of chloroprednisone. Chloroprednisone acetate was sold under the brand name Topilan as an anti-inflammatory agent.

Cyproterone belongs to a group of medications known as steroidal antiandrogens. It suppresses testosterone and its metabolites. It has approximately three-fold lower potency as an antagonist of the androgen receptor relative to cyproterone acetate. Cyproterone acetate is used to treat advanced prostate cancer and acne.

Anagestone acetate is a progestin medication, used in the 1960s in combination with the estrogen mestranol as a combined birth control pill. Toxicological study of chronic administration in dogs and monkeys showed the increased risk of developing malignant tumors in the mammary glands and a dose-dependent, nonprogressive decrease in hemoglobin and hematocrits. The drug was voluntarily withdrawn from the market in 1969.
