Paliperidone cas 144598-75-4

Off White to Light Orange Coloured SolidPaliperidone, the C-9 hydroxylated active metabolite of the antipsychotic agent risperidone, is the newest atypical antipsychotic to join the market following the introductions of olanzapine (ZyprexaTM), risperidone (RisperdalTM), quetiapine(SeroquelTM), and ziprasidone (GeodonTM). Compared to its parent, paliperidone has improved PK properties and a reduced potential for drug interactions.

3-{2-[4-(6-fluoro-1,2-benzoxazol-3-yl)piperidin-1-yl]ethyl}-9-hydroxy-2-methyl-6,7,8,9-tetrahydropyrido[1,2-a]pyrimidin-4-one is a member of the class of pyridopyrimidines that is 9-hydroxy-2-methyl-6,7,8,9-tetrahydropyrido[1,2-a]pyrimidin-4-one carrying an additional 2-[4-(6-fluoro-1,2-benzoxazol-3-yl)piperidin-1-yl]ethyl group at position 2. It is a member of 1,2-benzoxazoles, a heteroarylpiperidine, an organofluorine compound, a pyridopyrimidine and a secondary alcohol.|Paliperidone is the primary active metabolite of risperidone. The mechanism of action is unknown but it is likely to act via a similar pathway to risperidone. It has been proposed that the drug's therapeutic activity in schizophrenia is mediated through a combination of central dopamine Type 2 (D2) and serotonin Type 2 (5HT2A) receptor antagonism. Paliperidone is also active as an antagonist at alpha 1 and alpha 2 adrenergic receptors and H1 histaminergic receptors, which may explain some of the other effects of the drug. Paliperidone was approved by the FDA for treatment of schizophrenia on December 20, 2006.|Paliperidone is a second generation (atypical) antipsychotic agent that is available in both oral and long acting parenteral forms and is used in the treatment of schizophrenia and schizoaffective disorder. Paliperidone is associated with a low rate of serum aminotransferase elevations during therapy, but has not been linked to instances of clinically apparent acute liver injury.|Lumateperone is a second generation (atypical) antipsychotic agent that is used in the treatment of schizophrenia. Lumateperone is associated with a low rate of serum aminotransferase elevations during therapy, but has not been linked to instances of clinically apparent acute liver injury.|A benzisoxazole derivative and active metabolite of RISPERIDONE that functions as a DOPAMINE D2 RECEPTOR ANTAGONIST and SEROTONIN 5-HT2 RECEPTOR ANTAGONIST. It is an ANTIPSYCHOTIC AGENT used in the treatment of SCHIZOPHRENIA.
