Carisbamate (YKP 509, proposed trade name Comfyde) is an experimental anticonvulsant drug that was under development by Johnson & Johnson Pharmaceutical Research and Development but never marketed.
A phase II clinical trial in the treatment of partial seizures demonstrated that the compound has efficacy in the treatment of partial seizures and a good safety profile. Since late 2006, the compound has been undergoing a large multicenter phase III clinical trial for the treatment of partial seizures. Its mechanism of action is unknown. [1] [2]
A double-blind, placebo-controlled trial of carisbamate in 323 patients with migraine determined that carisbamate was well tolerated at doses up to 600 mg/day, but it failed to demonstrate that the drug was sufficiently more effective than placebo in migraine prophylaxis. [3]
In 1998, the compound was in-licensed from SK Corp. (currently Life Science Business Division of SK Holdings), a South Korean company. On October 24, 2008, Johnson & Johnson announced that it had submitted a New Drug Application to the U.S. Food and Drug Administration (FDA) for carisbamate. [4] Johnson & Johnson received provisional approval by the FDA to market carisbamate under the brand name of Comfyde. However, on August 21, 2009, Johnson & Johnson reported that the FDA had failed to give marketing approval.
Topiramate, sold under the brand name Topamax among others, is a medication used to treat epilepsy and prevent migraines. It has also been used in alcohol dependence and essential tremor. For epilepsy this includes treatment for generalized or focal seizures. It is taken orally.
Duloxetine, sold under the brand name Cymbalta among others, is a medication used to treat major depressive disorder, generalized anxiety disorder, fibromyalgia, neuropathic pain and central sensitization. It is taken by mouth.
Rimonabant (also known as SR141716; trade names Acomplia, Zimulti) is an anorectic antiobesity drug approved in Europe in 2006 but was withdrawn worldwide in 2008 due to serious psychiatric side effects; it was never approved in the United States. Rimonabant is an inverse agonist for the cannabinoid receptor CB1 and was first-in-class for clinical development.
Candesartan is an angiotensin receptor blocker used mainly for the treatment of high blood pressure and congestive heart failure. Candesartan has a very low maintenance dose. Like Olmesartan, the metabolism of the drug is unusual as it is a cascading prodrug. Candesartan has good bioavailibility and is the most potent by weight of the AT-1 receptor antagonists.
CX717 is an ampakine compound created by Christopher Marrs and Gary Rogers in 1996 at Cortex Pharmaceuticals. It affects the neurotransmitter glutamate, with trials showing the drug improves cognitive functioning and memory.
Zonisamide, sold under the brand name Zonegran among others, is a medication used to treat the symptoms of epilepsy and Parkinson's disease. Chemically it is a sulfonamide. It serves as an anticonvulsant used primarily as an adjunctive therapy in adults with Parkinson's disease, partial-onset seizures; infantile spasm, mixed seizure types of Lennox–Gastaut syndrome, myoclonic and generalized tonic clonic seizure. Despite this it is also sometimes used as a monotherapy for partial-onset seizures.
Peramivir is an antiviral drug developed by BioCryst Pharmaceuticals for the treatment of influenza. Peramivir is a neuraminidase inhibitor, acting as a transition-state analogue inhibitor of influenza neuraminidase and thereby preventing new viruses from emerging from infected cells. It is approved for intravenous administration.
Mecamylamine is a non-selective, non-competitive antagonist of the nicotinic acetylcholine receptors (nAChRs) that was introduced in the 1950s as an antihypertensive drug. In the United States, it was voluntarily withdrawn from the market in 2009 but was brought to market in 2013 as Vecamyl and eventually was marketed by Turing Pharmaceuticals.
Rufinamide is an anticonvulsant medication. It is used in combination with other medication and therapy to treat Lennox–Gastaut syndrome and various other seizure disorders. Rufinamide, a triazole derivative, was developed in 2004 by Novartis Pharma, AG, and is manufactured by Eisai.
Gepirone, sold under the brand name Exxua, is a medication used for the treatment of major depressive disorder. It is taken orally.
Lacosamide, sold under the brand name Vimpat among others, is a medication used for the treatment of partial-onset seizures and primary generalized tonic-clonic seizures. It is used by mouth or intravenously.
Tasimelteon, sold under the brand name Hetlioz, is a medication approved by the U.S. Food and Drug Administration (FDA) in January 2014, for the treatment of non-24-hour sleep–wake disorder. In June 2014, the European Medicines Agency (EMA) accepted an EU filing application for tasimelteon and in July 2015, the drug was approved in the European Union for the treatment of non-24-hour sleep-wake rhythm disorder in totally blind adults, but not in the case of non-24 in sighted people.
Retigabine (INN) or ezogabine (USAN) is an anticonvulsant used as an adjunctive treatment for partial epilepsies in treatment-experienced adult patients. The drug was developed by Valeant Pharmaceuticals and GlaxoSmithKline. It was approved by the European Medicines Agency under the trade name Trobalt on March 28, 2011, and by the United States Food and Drug Administration (FDA), under the trade name Potiga, on June 10, 2011. Production was discontinued in June 2017.
Pimavanserin, sold under the brand name Nuplazid, is an atypical antipsychotic which is approved for the treatment of Parkinson's disease psychosis and is also being studied for the treatment of Alzheimer's disease psychosis, schizophrenia, agitation, and major depressive disorder. Unlike other antipsychotics, pimavanserin is not a dopamine receptor antagonist.
Calcitonin gene-related peptide (CGRP) receptor antagonists are a class of drugs that act as antagonists of the calcitonin gene-related peptide receptor (CGRPR).
Crofelemer is an antidiarrheal indicated for the symptomatic relief of non-infectious diarrhea in adult patients with HIV/AIDS on antiretroviral therapy. Other possible uses include diarrhea in children, acute infectious diarrhea, and diarrhea in patients with irritable bowel syndrome. It is a purified oligomeric proanthocyanidin from "dragon's blood", the sap of the South American tree Croton lechleri.
Efinaconazole, sold under the brand name Jublia among others, is a triazole antifungal medication. It is approved for use in the United States, Canada, and Japan as a 10% topical solution for the treatment of onychomycosis. Efinaconazole acts as a 14α-demethylase inhibitor.
Fremanezumab, sold under the brand name Ajovy, is a medication used to prevent migraines in adults. It is given by injection under the skin.
Psychoplastogens are a group of small molecule drugs that produce rapid and sustained effects on neuronal structure and function, intended to manifest therapeutic benefit after a single administration. Several existing psychoplastogens have been identified and their therapeutic effects demonstrated; several are presently at various stages of development as medications including Ketamine, MDMA, Scopolamine, and the serotonergic psychedelics, including LSD, psilocin, DMT, and 5-MeO-DMT. Compounds of this sort are being explored as therapeutics for a variety of brain disorders including depression, addiction, and PTSD. The ability to rapidly promote neuronal changes via mechanisms of neuroplasticity was recently discovered as the common therapeutic activity and mechanism of action.
