Cariprazinum est substantia antipsychotica, agonista dopamini partialis (D₃ > D₂), ad schizophreniam tractandam^[1]. In senectute periculum apoplexiae cerebri auctum est. Neque valor prolactini auctus neque intervallum QT prolongatum observantur.

Historia

Ante annum 2008 grex Hungaricus societatis Richter Gedeon Nyrt. varias substantias receptoria dopamini D₃ et minus D₂ inhibentes investigavit^[2]. Paulo post sub nomen Cariprazini pristinum RGH-188 inventum erat^[3] et anno 2012 Cariprazinum praesentatum est^[4].

Pharmacocinetica

Tempus semivitae biologicum Cariprazini est duo dies usque ad quinque dies. Cariprazinum substratum Cytochromatis P450 CYP3A4 (minus CYP2D6) est.
Metaboliti sunt Desmethylo-Cariprazinum (DCAR) et Di-Desmethylo-Cariprazinum (DDCAR)^[7]. Tempora semivitae biologica metabolitorum Cariprazino magis longiora sunt, ita Desmethylo-Cariprazino 2-3 hebdomades est.

Metaboliti

Cytochromatis CYP3A4 ope in duo gradus primo DCAR deinde DDCAR oriuntur.

Effectus Cariprazini

In schizophrenia Cariprazinum effectus sympatomum negativorum deminuat^[8].
