Conjugated Synthetic B

Conjugated Synthetic B Uses, Dosage, Side Effects, Food Interaction and all others data.

Synthetic conjugated estrogens, B tablets contain a blend of ten synthetic estrogenic substances. The estrogenic substances are: sodium estrone sulfate, sodium equilin sulfate, sodium 17α-dihydroequilin sulfate, sodium 17α-estradiol sulfate, sodium 17β dihydroequilin sulfate, sodium 17α-dihydroequilenin sulfate, sodium 17β-dihydroequilenin sulfate, sodium equilenin sulfate, sodium 17β-estradiol sulfate, and sodium Δ8,9-dehydroestrone sulfate. This blend of ten estrogen derivatives are plant-derived forms of endogenous estrogens and contain many of the same compounds as the Conjugated Equine Estrogens (CEEs), although they are not considered to be equivalent. Available as the product Cenestin (FDA), this combination of plant-derived estrogenic compounds is indicated for the treatment of moderate to severe vasomotor symptoms, vulvovaginal atrophy, vaginal dryness, and paint with intercourse associated with menopause.

All estrogen products mimic the effects of endogenous estrogens in the body which are responsible for the development and maintenance of the female reproductive system and secondary sexual characteristics. Estrogens act by binding to estrogen receptors on a wide variety of tissues in the body and modulating the pituitary secretion of the gonadotropins, luteinizing hormone (LH) and follicle stimulating hormone (FSH) through a negative feedback mechanism. Prior to menopause, the primary source of estrogen is the ovarian follicle, which secretes 70-500 micrograms of estradiol daily, depending on the phase of the menstrual cycle. However, once a woman stops ovulating there is a sharp decline in the production of progesterone and estradiol by the ovaries and a consequent fluctuation in LH and FSH due to a lack of feedback control. This shift in hormone production is largely responsible for many of the symptoms experienced during and after menopause and includes hot flashes and other vasomotor symptoms, painful intercourse, vaginal dryness, and vulvovaginal atrophy. These symptoms are able to be reduced by replacing many of the hormones lost during and following menopause with synthetic or naturally occurring forms, in a therapy known as Hormone Replacement Therapy (HRT).

Pharmacologic estrogen products are available in a variety of formats. Although many of them contain several compounds in common (such as the estrogen derivatives sodium estrone sulfate and sodium equilin sulfate), they vary by their original source (such as horse-, human-, or plant-derived), and the remaining mixture of estrogenic derivatives. Conjugated Equine Estrogens (CEEs) are derived from the urine of pregnant mares and contain a blend of at least 10 estrogen derivatives. Marketed under the brand name Premarin, CEEs are the most frequently used form of conjugated estrogens. There is currently no generic form of CEEs available as a detailed analytical characterization of the active ingredients or of their estrogenic activity is not available at this time. Conjugated estrogens are also available in a plant-derived synthetic form that replicates the naturally occurring, horse-derived forms. Available as either "Synthetic Conjugated Estrogens, A" containing 9 estrogen derivatives (available as Cenestin) or as "Conjugated Synthetic B" containing 10 estrogen derivatives (available as Enjuvia), these products are isolated as precursors from yam or soy plants and then chemically modified to mimic the products available in their naturally occurring form.

Uses

Conjugated Synthetic B is a mixture of estrogens used to treat a variety of postmenopausal symptoms, including vaginal dryness.

For the treatment of moderate to severe vasomotor symptoms due to menopause and for the treatment of moderate to severe vaginal dryness, pain with intercourse, and symptoms of vulvar and vaginal atrophy due to menopause.

Conjugated Synthetic B is also used to associated treatment for these conditions: Moderate Dyspareunia, Moderate Menopausal Vasomotor Symptoms, Moderate Vaginal dryness, Moderate Vulvovaginal atrophy, Severe Dyspareunia, Severe Vaginal dryness, Severe Vasomotor Symptoms Associated With Menopause, Severe menopausal vulvovaginal atrophy

How Conjugated Synthetic B works

Food Interaction

Avoid grapefruit products. Grapefruit inhibits CYP3A4 metabolism, which may increase the serum concentration of synthetic conjugated estrogens, B.
Avoid St. John's Wort. This herb induces CYP3A4 metabolism and may reduce serum levels of synthetic conjugated estrogens, B.
Take with or without food.

Volume of Distribution

The distribution of exogenous estrogens is similar to that of endogenous estrogens. Estrogens are widely distributed in the body and are generally found in higher concentrations in the sex hormone target organs.

Elimination Route

Synthetic conjugated estrogens, B are soluble in water and are well absorbed from the gastrointestinal tract after release from the drug formulation. The tablets release synthetic conjugated estrogens, B slowly over a period of several hours.
