Endoxifen
Endoxifen, also known as 4-hydroxy-''N''-desmethyltamoxifen, is a nonsteroidal selective estrogen receptor modulator (SERM) of the triphenylethylene group as well as a protein kinase C (PKC) inhibitor. It is under development for the treatment of estrogen receptor-positive breast cancer and for the treatment of mania in bipolar disorder. It is taken by mouth. Endoxifen is an active metabolite of tamoxifen and has been found to be effective in patients that have failed previous hormonal therapies (tamoxifen, aromatase inhibitors, and fulvestrant). The prodrug tamoxifen is metabolized by the CYP2D6 enzyme to produce endoxifen and afimoxifene (4-hydroxytamoxifen). Currently, endoxifen is approved by Drugs Controller General of India for the acute treatment of manic episode with or without mixed features of Bipolar I disorder. It is manufactured and sold by Intas Pharmaceuticals under the brand name Zonalta. Medical uses Bipolar disorder Endoxifen is used to treat manic ...

Oral Administration
Oral administration is a route of administration whereby a substance is taken through the Human mouth, mouth, swallowed, and then processed via the digestive system. This is a common route of administration for many medications. Oral administration can be easier and less painful than other routes of administration, such as Injection (medicine), 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 able to swallow. Terminology ''Per os'' (; ''P.O.'') is an adverbial phrase meaning literally from Latin "through the mouth" or "by mouth". The expression is used in medicine to describe a treatment that is taken orally (but not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bipolar I Disorder
Bipolar I disorder (BD-I; pronounced "type one bipolar disorder") is a type of bipolar spectrum disorder characterized by the occurrence of at least one manic episode, with or without mixed or psychotic features. Most people also, at other times, have one or more depressive episodes. Typically, these manic episodes can last at least 7 days for most of each day to the extent that the individual may need medical attention, while the depressive episodes last at least 2 weeks. It is a type of bipolar disorder and conforms to the classic concept of manic-depressive illness, which can include psychosis during mood episodes. Diagnosis The essential feature of bipolar I disorder is a clinical course characterized by the occurrence of one or more manic episodes or mixed episodes. Often, individuals have had one or more major depressive episodes. One episode of mania is sufficient to make the diagnosis of bipolar disorder; the person may or may not have a history of major depressive d ...

Mixed Episode
A mixed affective state, formerly known as a mixed-manic or mixed episode, has been defined as a state wherein features and symptoms unique to both depression and (hypo)mania, including episodes of anguish, despair, self doubt, rage, excessive impulsivity and suicidal ideation, sensory overload, racing thoughts, heightened irritability, decreased "need" for sleep and other symptoms of depressive and manic states occur either simultaneously or in very short succession. In ''Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition'' nomenclature, a "mixed episode" no longer stands as an episode of illness ''unto itself''; rather, the symptomology specifier "with mixed features" can be applied to ''any'' major affective episode ( manic, hypomanic, or depressive), meaning that they are now officially also recognized in patients with bipolar II disorder and, by convention, major depressive disorder.

Manic Episode
Mania, also known as manic syndrome, is a psychiatric behavioral syndrome defined as a state of abnormally elevated arousal, affect, and energy level. During a manic episode, an individual will experience rapidly changing emotions and moods, highly influenced by surrounding stimuli. Although mania is often conceived of as a "mirror image" to depression, the heightened mood can be dysphoric as well as euphoric. As the mania intensifies, irritability can be more pronounced and result in anxiety or anger. The symptoms of mania include elevated mood (either euphoric or irritable), flight of ideas, pressure of speech, increased energy, decreased "need" and desire for sleep, and hyperactivity. They are most plainly evident in fully developed hypomanic states, however, in full-blown mania, these symptoms become progressively exacerbated. In severe manic episodes, these symptoms may even be obscured by other signs and symptoms characteristic of psychosis, such as delusions (i ...

Drugs Controller General Of India
A drug is any chemical substance other than a nutrient or an essential dietary ingredient, which, when administered to a living organism, produces a biological effect. Consumption of drugs can be via inhalation, injection, smoking, ingestion, absorption via a patch on the skin, suppository, or dissolution under the tongue. In pharmacology, a drug is a chemical substance, typically of known structure, which, when administered to a living organism, produces a biological effect. A pharmaceutical drug, also called a medication or medicine, is a chemical substance used to treat, cure, prevent, or diagnose a disease or to promote well-being. Traditionally drugs were obtained through extraction from medicinal plants, but more recently also by organic synthesis. Pharmaceutical drugs may be used for a limited duration, or on a regular basis for chronic disorders. Classification Pharmaceutical drugs are often classified into drug classes—groups of related drugs that have s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Afimoxifene
Afimoxifene, also known as 4-hydroxytamoxifen (4-OHT) and by its tentative brand name TamoGel, is a selective estrogen receptor modulator (SERM) of the triphenylethylene group and an active metabolite of tamoxifen. The drug is under development under the tentative brand name TamoGel as a topical gel for the treatment of hyperplasia of the breast. It has completed a phase II clinical trial for cyclical mastalgia, but further studies are required before afimoxifene can be approved for this indication and marketed. Afimoxifene is a SERM and hence acts as a tissue-selective agonist–antagonist of the estrogen receptors ERα and ERβ with mixed estrogenic and antiestrogenic activity depending on the tissue. It is also an agonist of the G protein-coupled estrogen receptor (GPER) with relatively low affinity (100–1,000 nM, relative to 3–6 nM for estradiol). In addition to its estrogenic and antiestrogenic activity, afimoxifene has been found to act as an antagoni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
