Premarin
Conjugated estrogens (CEs), or conjugated equine estrogens (CEEs), sold under the brand name Premarin among others, is an estrogen medication which is used in menopausal hormone therapy and for various other indications. It is a mixture of the sodium salts of estrogen conjugates found in horses, such as estrone sulfate and equilin sulfate. CEEs are available in the form of both natural preparations manufactured from the urine of pregnant mares and fully synthetic replications of the natural preparations. They are formulated both alone and in combination with progestins such as medroxyprogesterone acetate. CEEs are usually taken by mouth, but can also be given by application to the skin or vagina as a cream or by injection into a blood vessel or muscle. Side effects of CEEs include breast tenderness and enlargement, headache, fluid retention, and nausea among others. It may increase the risk of endometrial hyperplasia and endometrial cancer in women with an intact ute ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Menopausal Hormone Therapy
Hormone replacement therapy (HRT), also known as menopausal hormone therapy or postmenopausal hormone therapy, is a form of hormone therapy used to treat symptoms associated with female menopause. Effects of menopause can include symptoms such as hot flashes, accelerated skin aging, vaginal dryness, decreased muscle mass, and complications such as osteoporosis (bone loss), sexual dysfunction, and vaginal atrophy. They are mostly caused by low levels of female sex hormones (e.g. estrogens) that occur during menopause. Estrogens and progestogens are the main hormone drugs used in HRT. Progesterone is the main female sex hormone that occurs naturally and is also manufactured into a drug that is used in menopausal hormone therapy. Although both classes of hormones can have symptomatic benefit, progestogen is specifically added to estrogen regimens, unless the uterus has been removed, to avoid the increased risk of endometrial cancer. Unopposed estrogen therapy promotes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, and edema among ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Estrone Sulfate (medication)
Estrone sulfate (E1S) is an estrogen medication and naturally occurring steroid hormone. It is used in menopausal hormone therapy among other indications. As the sodium salt (sodium estrone sulfate), it is the major estrogen component of conjugated estrogens (Premarin) and esterified estrogens (Estratab, Menest). In addition, E1S is used on its own as the piperazine salt estropipate (piperazine estrone sulfate; Ogen). The compound also occurs as a major and important metabolite of estradiol and estrone. E1S is most commonly taken by mouth, but in the form of Premarin can also be taken by parenteral routes such as transdermal, vaginal, and injection. Medical uses E1S is used in menopausal hormone therapy among other indications. Pharmacology Pharmacodynamics E1S itself is essentially biologically inactive, with less than 1% of the relative binding affinity of estradiol for the estrogen receptors (ERs), ERα and ERβ. The compound acts as a prodrug of estrone and more impor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Estrone (medication)
Estrone (E1), sold under the brand names Estragyn, Kestrin, and Theelin among many others, is an estrogen medication and naturally occurring steroid hormone which has been used in menopausal hormone therapy and for other indications. It has been provided as an aqueous suspension or oil solution given by injection into muscle and as a vaginal cream applied inside of the vagina. It can also be taken by mouth as estradiol/estrone/estriol (brand name Hormonin) and in the form of prodrugs like estropipate (estrone sulfate; brand name Ogen) and conjugated estrogens (mostly estrone sulfate; brand name Premarin). Side effects of estrogens like estrone include breast tenderness, breast enlargement, headache, nausea, fluid retention, and edema, among others. Estrone is a naturally occurring and bioidentical estrogen, or an agonist of the estrogen receptor, the biological target of estrogens like endogenous estradiol. It is a relatively weak estrogen, with much lower activity tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medroxyprogesterone Acetate
Medroxyprogesterone acetate (MPA), also known as depot medroxyprogesterone acetate (DMPA) in injectable form and sold under the brand name Depo-Provera among others, is a hormonal medication of the progestin type. It is used as a method of birth control and as a part of menopausal hormone therapy. It is also used to treat endometriosis, abnormal uterine bleeding, paraphilia, and certain types of cancer. The medication is available both alone and in combination with an estrogen. It is taken by mouth, used under the tongue, or by injection into a muscle or fat. Common side effects include menstrual disturbances such as absence of periods, abdominal pain, and headaches. More serious side effects include bone loss, blood clots, allergic reactions, and liver problems. Use is not recommended during pregnancy as it may harm the baby. MPA is an artificial progestogen, and as such activates the progesterone receptor, the biological target of progesterone. It also has androg ...

Combination Drug
A combination drug is a combination of two or more pharmaceutical drugs as active ingredients combined into a single dosage form, typically as a ''fixed-dose combination'', with each constituent standardized to specifications of a fixed dose. Fixed-dose combinations are mass production, mass-produced and mass marketing, mass marketed, intended to serve as a near universal treatment for a large patient population with diverse medical histories, conditions, predisposition thereof, and treatment requirements. A ''polypill'' is a tablet (pharmacy), pharmacy or capsule (pharmacy), capsule containing four or more active ingredients, often needing to be Compounding, compounded at a specialized pharmacy in order to satisfy the specifications of a patient's personalized medical prescription, prescription and treatment plan, including dosage form, Dosage (pharmacology), medicinal dosing, and/or modified-release dosage, mechanism of release. Polypills encompass approved drug, approved prescr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Equilin Sulfate
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 combination drug preparations known as conjugated estrogens (CEEs; e.g. Premarin) and esterified estrogens (EEs; e.g. Estratab, Menest). CEEs is the most commonly used form of estrogen medications 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 th ...

Mare
A mare is an adult female horse or other equidae, 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. Reproductive cycle Mares carry their young (called foals) for approximately 11 months from conception to birth, the average range being 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 domestication, domesticated mare foals, she nurses the foal for at least four to six months before it is weaning, weaned, though wild horse, mares in the wild may allow a foal to nurse for up to a year.
