Pipamperone (INN, USAN, BAN), also known as carpiperone and floropipamide or fluoropipamide, and as floropipamide hydrochloride (JAN), is a typical antipsychotic of the butyrophenone family used in the treatment of schizophrenia.[1][2] It is or has been marketed under brand names including Dipiperon, Dipiperal, Piperonil, Piperonyl, and Propitan.[2] Pipamperone was discovered at Janssen Pharmaceutica in 1961, and entered clinical trials in the United States in 1963.[3]

Pharmacology[edit]




Pipamperon Neuraxpharm, 40mg



Pipamperone acts as an antagonist of the 5-HT2A,[4]5-HT2B,[5]5-HT2C[6]D2,[4]D3,[7]D4,[4][8]α1-adrenergic,[7] and α2-adrenergic receptors.[7] It shows much higher affinity for the 5-HT2A and D4 receptors over the D2 receptor (15-fold in the case of the D4 receptor, and even higher in the case of the 5-HT2A receptor),[4][7][9] being regarded as "highly selective" for the former two sites at low doses.[9][10] Pipamperone has low and likely insignificant affinity for the H1 and mACh receptors, as well as for other serotonin and dopamine receptors.[7]


Pipamperone is considered to have been a forerunner to the atypical antipsychotics, if not an atypical antipsychotic itself, due to its prominent serotonin antagonism.[11][12][13]



Antidepressant effects[edit]


Low-dose pipamperone (5 mg twice daily) has been found to accelerate and enhance the antidepressant effect of citalopram (40 mg once daily), in a combination (citalopram/pipamperone) referred to as PipCit (code name PNB-01).[9][14]

Full-time equivalent

Full-time equivalent From Wikipedia, the free encyclopedia Jump to navigation Jump to search Full-time equivalent ( FTE ) or whole time equivalent ( WTE ) is a unit that indicates the workload of an employed person (or student) in a way that makes workloads or class loads comparable [1] across various contexts. FTE is often used to measure a worker's or student's involvement in a project, or to track cost reductions in an organization. An FTE of 1.0 is equivalent to a full-time worker or student, while an FTE of 0.5 signals half of a full work or school load. [2] Contents 1 U.S. Federal Government 2 In education 2.1 Example 3 Notes 4 References U.S. Federal Government [ edit ] In the U.S. Federal Government, FTE is defined by the Government Accountability Office (GAO) as the number of total hours worked divided by the maximum number of compensable hours in a full-time schedule as...
