Ubrogepant
Ubrogepant, sold under the brand name Ubrelvy, is a medication used for the acute (immediate) treatment of migraine with or without aura (a sensory phenomenon or visual disturbance) in adults. It is not indicated for the preventive treatment of migraine. Ubrogepant is a small-molecule calcitonin gene-related peptide receptor antagonist. It is the first drug in this class approved for the acute treatment of migraine. The most common side effects are nausea, tiredness and dry mouth. Ubrogepant is contraindicated for co-administration with strong CYP3A4 inhibitors. History Ubrogepant, also known as MK-1602, was discovered by scientists at Merck. The effectiveness of ubrogepant for the acute treatment of migraine was demonstrated in two randomized, double-blind, placebo-controlled trials. In these studies, 1,439 adult patients with a history of migraine, with and without aura, received the approved doses of ubrogepant to treat an ongoing migraine. In both studies, the percentages ...

Calcitonin Gene-related Peptide Receptor Antagonists
Calcitonin gene-related peptide (CGRP) receptor antagonists, commonly known as gepants, are a class of drugs that act as antagonists of the calcitonin gene-related peptide receptor (CGRPR). Several monoclonal antibodies that bind to the CGRP receptor or peptide have been approved for prevention of migraine. Nerve activation triggers the release of CGRP and other neuropeptides, leading to inflammation, pain, and swelling. Three small molecule CGRPR antagonists are approved in the U.S. as antimigraine agents. Drugs of this class have also been investigated for use in osteoarthritis. Examples Non-peptide small molecules * Ubrogepant is approved for acute treatment of migraines * Rimegepant (BMS-927711) is approved for acute and preventative treatment of migraines * Atogepant (AGN-241689) is approved for preventative treatment of migraines * Zavegepant (BHV- 3500) is a nasal spray approved for acute treatment of migraines. * Telcagepant (MK-0974), reached phase III clinical tria ...

Antimigraine Drugs
Antimigraine drugs are medications intended to reduce the effects or intensity of migraine headache. They include drugs for the treatment of acute migraine symptoms as well as drugs for the prevention of migraine attacks. Treatment of acute symptoms Examples of specific antimigraine drug classes include triptans (first line option), ergot alkaloids, ditans and gepants. Migraines can also be treated with unspecific analgesics such as nonsteroidal anti-inflammatory drugs (NSAIDs) or acetaminophen. Opioids are not recommended for treatment of migraines. Triptans The triptan drug class includes 1st generation sumatriptan Sumatriptan, sold under the brand name Imitrex among others, is a medication used to treat migraine headaches and cluster headaches. It is taken Oral administration, orally, Nasal administration, intranasally, or by Subcutaneous injection, su ... (which has poor bioavailability), and second generation zolmitriptan.

By Mouth
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] |
Spiro Compounds
In organic chemistry, spiro compounds are compounds that have at least two molecular rings sharing one common atom. Simple spiro compounds are bicyclic (having just two rings). The presence of only one common atom connecting the two rings distinguishes spiro compounds from other bicyclics.For all four categories, see The specific chapters can be found aan respectively, same access date. For the description featuring adjacent atoms for all but the isolated category, see Clayden, op. cit. Spiro compounds may be fully carbocyclic (all carbon) or heterocyclic (having one or more non-carbon atom). One common type of spiro compound encountered in educational settings is a heterocyclic one— the acetal formed by reaction of a diol with a cyclic ketone. The common atom that connects the two (or sometimes three) rings is called the ''spiro atom''. In carbocyclic spiro compounds like spiro .5ndecane, the spiro-atom is a quaternary carbon, and as the ''-ane'' ending implies, these ar ...

Trifluoromethyl Compounds
The trifluoromethyl group is a functional group that has the formula In science, a formula is a concise way of expressing information symbolically, as in a mathematical formula or a ''chemical formula''. The informal use of the term ''formula'' in science refers to the general construct of a relationship betwe ... . The naming of is group is derived from the methyl group (which has the formula ), by replacing each hydrogen atom by a fluorine atom. Some common examples are trifluoromethane , 1,1,1-trifluoroethane , and hexafluoroacetone . Compounds with this group are a subclass of the organofluorines. Properties The trifluoromethyl group has a significant electronegativity that is often described as being intermediate between the electronegativities of fluorine and chlorine. For this reason, trifluoromethyl-substituted compounds are often strong acids, such as trifluoromethanesulfonic acid and trifluoroacetic acid. Conversely, the trifluoromethyl group lowers the basicity of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drugs Developed By AbbVie
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 simi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xerostomia
Xerostomia, also known as dry mouth, is a subjective complaint of dryness in the mouth, which may be associated with a change in the composition of saliva, reduced salivary flow, or have no identifiable cause. This symptom is very common and is often seen as a side effect of many types of medication. It is more common in older people (mostly because individuals in this group are more likely to take several medications) and in people who breathe through their mouths. Dehydration, radiotherapy involving the salivary glands, chemotherapy and several diseases can cause reduced salivation (hyposalivation), or a change in saliva consistency and hence a complaint of xerostomia. Sometimes there is no identifiable cause, and there may sometimes be a psychogenic reason for the complaint. Definition Xerostomia is the subjective sensation of dry mouth, which is often (but not always) associated with hypofunction of the salivary glands. The term is derived from the Greek words ξηρός (' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fatigue is a state of tiredness (which is not sleepiness), exhaustion or loss of energy. It is a signs and symptoms, symptom of any of various diseases; it is not a disease in itself. Fatigue (in the medical sense) is sometimes associated with medical conditions including autoimmune disease, organ failure, chronic pain conditions, mood disorders, heart disease, infectious diseases, and post-infectious-disease states. However, fatigue is complex and in up to a third of primary care cases no medical or psychiatric diagnosis is found. Fatigue (in the general usage sense of normal tiredness) often follows prolonged physical or mental activity. Physical fatigue results from muscle fatigue brought about by intense physical activity. Mental fatigue results from prolonged periods of Cognition, cognitive activity which impairs cognitive ability, can manifest as sleepiness, lethargy, or directed attention fatigue, and can also impair physical performance.
