Estrogenic Substances
Estrogenic substances, also referred to as natural estrogens and sold under the brand name Amniotin among others, is an estrogen medication which was marketed in the 1930s and 1940s and is no longer available. It was a purified extract of animal material such as horse urine, placenta, and/or amniotic fluid, and contained a non- crystalline mixture of estrogens, including estrone, 17β-estradiol, 17α-estradiol, and/or equilin. The medication was thought to contain estrone as its major active ingredient and was described as an estrone-like preparation, or as "essentially estrone". Estrogenic substances was originally produced from the urine of pregnant women, placenta, and/or amniotic fluid, but by the early 1940s, it was manufactured exclusively from the urine of stallions or pregnant mares, similarly to almost all other estrogen preparations on the market. Estrogenic substances was marketed under a variety of different brand names including ''Amniotin'' (Squibb), ''Equine Estr ...

Estrogen (medication)
An estrogen (E) is a type of medication which is used most commonly in hormonal birth control and menopausal hormone therapy, and as part of feminizing hormone therapy for transgender women. They can also be used in the treatment of hormone-sensitive cancers like breast cancer and prostate cancer and for various other indications. Estrogens are used alone or in combination with progestogens. They are available in a wide variety of formulations and for use by many different routes of administration. Examples of estrogens include bioidentical estradiol, natural conjugated estrogens, synthetic steroidal estrogens like ethinylestradiol, and synthetic nonsteroidal estrogens like diethylstilbestrol. Estrogens are one of three types of sex hormone agonists, the others being androgens/anabolic steroids like testosterone and progestogens like progesterone. Side effects of estrogens include breast tenderness, breast enlargement, headache, nausea, fluid retention, and edema among other ...

Mixture
In chemistry, a mixture is a material made up of two or more different chemical substances which are not chemically bonded. A mixture is the physical combination of two or more substances in which the identities are retained and are mixed in the form of Solution (chemistry), solutions, Suspension (chemistry), suspensions and colloids. Mixtures are one product of mechanically blending or mixing chemical substances such as chemical element, elements and Compound (chemistry), compounds, without chemical bonding or other chemical change, so that each ingredient substance retains its own chemical properties and makeup. Despite the fact that there are no chemical changes to its constituents, the physical properties of a mixture, such as its melting point, may differ from those of the components. Some mixtures can be separation process, separated into their components by using physical (mechanical or thermal) means. Azeotropes are one kind of mixture that usually poses considerable diffi ...

Route Of Administration
A route of administration in pharmacology and toxicology is the way by which a medication, drug, fluid, poison, or other substance is taken into the body. Routes of administration are generally classified by the location at which the substance is applied. Common examples include oral administration, oral and intravenous therapy, intravenous administration. Routes can also be classified based on where the target of action is. Action may be topical medication, topical (local), enteral administration, enteral (system-wide effect, but delivered through the gastrointestinal tract), or #Parenteral, parenteral (systemic action, but delivered by routes other than the GI tract). Route of administration and dosage form are aspects of drug delivery. Classification Routes of administration are usually classified by application location (or exposition). The route or course the active substance takes from application location to the location where it has its target effect is usually rather ...

Pharmaceutical Form
Dosage forms (also called unit doses) are pharmaceutical drug products in the form in which they are marketed for use, with a specific mixture of active ingredients and inactive components (excipients), in a particular configuration (such as a capsule shell, for example), and apportioned into a particular dose. For example, two products may both be amoxicillin, but one is in 500 mg capsules and another is in 250 mg chewable tablets. The term unit dose can also sometimes encompass non-reusable ''packaging'' as well (especially when each drug product is individually packaged), although the FDA distinguishes that by ''unit-dose "packaging" or "dispensing"''. Depending on the context, ''multi(ple) unit dose'' can refer to distinct drug products ''packaged'' together, or to a ''single'' drug product containing multiple drugs and/or doses. The term dosage form can also sometimes refer ''only'' to the pharmaceutical formulation of a drug product's constituent drug substance(s) and any ble ...

Armour And Company
Armour & Company was an American company and was one of the five leading firms in the meat packing industry. It was founded in Chicago, in 1867, by the Armour brothers led by Philip Danforth Armour. By 1880, the company had become Chicago's most important business and had helped make Chicago and its Union Stock Yards the center of America's meatpacking industry. During the same period, its facility in Omaha, Nebraska, boomed, making the city's meatpacking industry the largest in the nation by 1959. In connection with its meatpacking operations, the company also ventured into pharmaceuticals (Armour Pharmaceuticals) and soap manufacturing, introducing Dial soap in 1948. Presently, the Armour food brands are split between Smithfield Foods (for refrigerated meat - "Armour Meats") and ConAgra Brands (for canned shelf-stable meat products - "Armour Star"). The Armour pharmaceutical brand is owned by Forest Laboratories. Dial soap is now owned by Henkel. History 1863–1970 Armo ...

Upjohn
The Upjohn Company was a pharmaceutical manufacturing firm founded in 1886 in Hastings, Michigan, by Dr. William E. Upjohn who was an 1875 graduate of the University of Michigan medical school. The company was originally formed to make ''friable pills'', which were specifically designed to be easily digested. These could be "reduced to a powder under the thumb", a strong marketing argument at the time. History Upjohn developed a process for the large scale production of cortisone. The oxygen atom at the 11 position in this steroid is an absolute requirement for biological activity. There are however no known natural sources for starting materials that contain that feature. The only method for preparing this drug prior to 1952 was a lengthy synthesis starting from cholic acid isolated from bile. In 1952, two Upjohn biochemists, Dury Peterson and Herb Murray announced that they were able to introduce this crucial oxygen atom by fermentation of the steroid progesterone with a comm ...

Mare
A mare is an adult female horse or other equine. In most cases, a mare is a female horse over the age of three, and a filly is a female horse three and younger. In Thoroughbred horse racing, a mare is defined as a female horse more than four years old. The word can also be used for other female equine animals, particularly mules and zebras, but a female donkey is usually called a "jenny". A broodmare is a mare used for breeding. A horse's female parent is known as its dam. Reproductive cycle Mares carry their young (called foals) for approximately 11 months from conception to birth. (Average range 320–370 days.)Ensminger, M. E. ''Horses and Horsemanship: Animal Agriculture Series.'' Sixth Edition. Interstate Publishers, 1990. p. 156 Usually just one young is born; twins are rare. When a domesticated mare foals, she nurses the foal for at least four to six months before it is weaned, though mares in the wild may allow a foal to nurse for up to a year. The estrous cycle ...

Stallion
A stallion is a male horse that has not been gelded (castrated). Stallions follow the conformation and phenotype of their breed, but within that standard, the presence of hormones such as testosterone may give stallions a thicker, "cresty" neck, as well as a somewhat more muscular physique as compared to female horses, known as ''mares'', and castrated males, called ''geldings''. Temperament varies widely based on genetics, and training, but because of their instincts as herd animals, they may be prone to aggressive behavior, particularly toward other stallions, and thus require careful management by knowledgeable handlers. However, with proper training and management, stallions are effective equine athletes at the highest levels of many disciplines, including horse racing, horse shows, and international Olympic competition. "Stallion" is also used to refer to males of other equids, including zebras and donkeys. Herd behavior Contrary to popular myths, many stallions do no ...

Equilin
Equilin is a naturally occurring estrogen sex hormone found in horses as well as a medication. It is one of the estrogens present in the estrogen mixtures known as conjugated estrogens (CEEs; brand name Premarin) and esterified estrogens (EEs; Estratab, Menest). CEEs is the most commonly used form of estrogen in hormone replacement therapy (HRT) for menopausal symptoms in the United States. Estrone sulfate is the major estrogen in CEEs (about 50%) while equilin sulfate is the second major estrogen in the formulation, present as about 25% of the total. Pharmacology Pharmacodynamics Equilin is an estrogen, or an agonist of the estrogen receptors (ERs), the ERα and ERβ. In terms of relative binding affinity for the ERs, equilin has about 13% and 49% of that of estradiol for the ERα and ERβ, respectively. Analogously to the reversible transformation of estrone into estradiol by 17β-hydroxysteroid dehydrogenase, equilin can be converted into the more potent estrogen 17β-dihydro ...
