Ondansetron, sold under the brand name Zofran among others, is a medication used to prevent nausea and vomiting caused by chemotherapy, radiation therapy, migraines, or surgery. [8] It is also effective for treating gastroenteritis. [9] [10] It can be given orally (by mouth), intramuscularly (injection into a muscle), or intravenously ...
Ondansetron was approved by the U.S. Food and Drug Administration in 1991, and has since become available in several other countries, including the UK, Ireland, Australia, Canada, France and Brazil. As of 2008, ondansetron and granisetron are the only 5-HT 3 antagonists available as a generic drug in the United States. Ondansetron may be given ...

In pharmacology, the term mechanism of action (MOA) refers to the specific biochemical interaction through which a drug substance produces its pharmacological effect. [2] A mechanism of action usually includes mention of the specific molecular targets to which the drug binds, such as an enzyme or receptor . [ 3 ]
Although some non-selective serotonin antagonists may have a particular affinity for a specific 5-HT receptor (and thus may be listed below e.g., methysergide), they still may also possess a generalised non-selective action. They include, but are not limited to: Chlorpromazine; Cyproheptadine; Metergoline; Methysergide; Mianserin; Mirtazapine ...
In 2001, the FDA changed the labeling requirements for droperidol injection to include a Black Box Warning, citing concerns of QT prolongation and torsades de pointes.The evidence for this is disputed, with 9 reported cases of torsades in 30 years and all of those having received doses in excess of 5 mg. [9] QT prolongation is a dose-related effect, [10] and it appears that droperidol is not a ...
In 1944 Howard Florey and Ernst Boris Chain mass-produced penicillin. In 1948 Raymond P. Ahlquist published his seminal work where he divided adrenoceptors into α- and β-adrenoceptor subtypes, this allowed a better understanding of drugs mechanisms of action. In 1987, after Montreal Protocol, CFC inhalers were phased out and HFA inhalers ...
Palonosetron does not relevantly inhibit or induce cytochrome P450 liver enzymes. There are case reports about serotonin syndrome when the drug is combined with serotonergic substances, such as selective serotonin reuptake inhibitors (SSRIs) and serotonin–norepinephrine reuptake inhibitors (SNRIs), two common types of antidepressants.
