Description
(extracted from source data)
TOXICITY Ld50 in rats, 48 mg/kg [L1520].; Prolonged Qtc interval. Monitoring with regular ECGs is recommended [L1525]. ; ; ;
MOA Pipamperone binds mainly to 5-HT2A receptors, with a nearly equal affinity to D4 receptors and a moderate affinity for 5-HT2C, D2, D3, 1- and 2B-adrenoceptors [A12816].; ; This drug is a selective 5-HT2A, D1 and D4 antagonist [L1516, A32507]. Extrapyramidal adverse effects also appear to be limited in pipamperone treatment compared to traditional antipsychotic medications due to its high receptor selectivity [L1514].; ; Pipamperone has a 15-fold higher affinity for D4 than D2 receptors. It has been suggested that D4 receptors may play a role in the modulation of GABAergic neuronal activity by dopamine [A12816]. ;
PHARMACODYNAMICS Pipamperone is an antipsychotic medication that has sedative effects, which may be beneficial in the management of agitation and disordered sleep [A32062]. Pipamperone, showing antidopaminergic and anti-serotonergic properties, has been noted for its anti-; agitation effects and for its ability to normalize sleep rhythms in psychiatric patients [A12816]. One study showed that pipamperone increased the expression of D4 (dopaminergic) receptors, explaining its helpfulness in decreasing positive psychotic symptoms, such as delusions and hallucinations [L1524].
