Bazedoxifene
Bazedoxifene, used as bazedoxifene acetate, is a medication for bone problems and possibly (pending more study) for cancer. It is a third-generation selective estrogen receptor modulator (SERM). Since late 2013 it has had U.S. FDA approval for bazedoxifene as part of the combination drug Duavee in the prevention (not treatment) of postmenopausal osteoporosis. It is also being studied for possible treatment of breast cancer and pancreatic cancer. Medical uses Bazedoxifene is used in the treatment of postmenopausal osteoporosis. Available forms Bazedoxifene is marketed both alone and in combination with conjugated estrogens. Pharmacology Pharmacodynamics Bazedoxifene is a selective estrogen receptor modulator (SERM), or a mixed agonist and antagonist of the estrogen receptor (ER) in different tissues. Chemistry The drug is a member of the 2-phenylindole group of SERMs, along with zindoxifene and pipendoxifene. History Development Bazedoxifene was developed by Pfizer fol ...

Selective Estrogen Receptor Modulator
Selective estrogen receptor modulators (SERMs), also known as estrogen receptor agonist/antagonists (ERAAs), are a class of drugs that act on the estrogen receptor (ER). A characteristic that distinguishes these substances from pure ER agonists and antagonists (that is, full agonists and silent antagonists) is that their action is different in various tissues, thereby granting the possibility to selectively inhibit or stimulate estrogen-like action in various tissues. Medical uses SERMs are used for various estrogen-related diseases, including treatment of ovulatory dysfunction in the management of infertility, treatment and prevention of postmenopausal osteoporosis, treatment and reduction in risk of breast cancer and treatment of dyspareunia due to menopause. SERM is also used in combination with conjugated estrogens indicated for the treatment of estrogen deficiency symptoms, and vasomotor symptoms associated with menopause. SERMs are used dependent on their pattern of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pipendoxifene
Pipendoxifene (INN) (developmental code name ERA-923) is a nonsteroidal selective estrogen receptor modulator (SERM) that was under development by Ligand Pharmaceuticals and Wyeth-Ayerst Laboratories (now Wyeth) for the treatment of breast cancer but was not marketed. It is a member of the 2-phenylindole group of SERMs and is structurally related to zindoxifene and the marketed bazedoxifene. The drug reached phase II clinical trials before its development was discontinued. It was synthesized at the same time as bazedoxifene and was intended as a backup drug for bazedoxifene, only to be developed further if bazedoxifene had failed in clinical trials. No further development was reported after 2002 and it was formally announced that development had been terminated in November 2005. Unlike the SERM raloxifene Raloxifene, sold under the brand name Evista among others, is a medication used to prevent and treat osteoporosis in postmenopausal women and those on glucocorticoids.

Conjugated Estrogens
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 uterus i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zindoxifene
Zindoxifene (INN; former developmental code names D-16726, NSC-341952) is a nonsteroidal selective estrogen receptor modulator (SERM) that was under development in the 1980s and early 1990s for the treatment of breast cancer but was not marketed. It showed estrogenic-like activity in preclinical studies and failed to demonstrate effectiveness as a treatment for breast cancer in clinical trials. Zindoxifene was the lead compound of the distinct 2-phenylindole class of SERMs, and the marketed SERM bazedoxifene was derived from the major active metabolite of zindoxifene, D-15414 D-15414 is a nonsteroidal weak estrogen of the 2-phenylindole group which was never marketed. It is the major metabolite of the selective estrogen receptor modulator (SERM) zindoxifene (D-16726). D-15414 has high affinity for the estrogen rece .... Zindoxifene was first described in 1984.

Drug Development
Drug development is the process of bringing a new pharmaceutical drug to the market once a lead compound has been identified through the process of drug discovery. It includes preclinical research on microorganisms and animals, filing for regulatory status, such as via the United States Food and Drug Administration for an investigational new drug to initiate clinical trials on humans, and may include the step of obtaining regulatory approval with a new drug application to market the drug. The entire process – from concept through preclinical testing in the laboratory to clinical trial development, including Phase I–III trials – to approved vaccine or drug typically takes more than a decade. New chemical entity development Broadly, the process of drug development can be divided into preclinical and clinical work. Pre-clinical New chemical entities (NCEs, also known as new molecular entities or NMEs) are compounds that emerge from the process of drug discovery. Th ...

Oral Administration
Oral administration is a route of administration where a substance is taken through the mouth. Per os abbreviated to P.O. is sometimes used as a direction for medication to be taken orally. Many medications are taken orally because they are intended to have a systemic effect, reaching different parts of the body via the bloodstream, for example. Oral administration can be easier and less painful than other routes, such as injection. However, the onset of action is relatively low, and the effectiveness is reduced if it is not absorbed properly in the digestive system, or if it is broken down by digestive enzymes before it can reach the bloodstream. Some medications may cause gastrointestinal side effects, such as nausea or vomiting, when taken orally. Oral administration can also only be applied to conscious patients, and patients willing and able to swallow. Terminology ''Per os'' (; ''P.O.'') is an adverbial phrase meaning literally from Latin "through the mouth" or "by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
