Historia

recensere

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

recensere

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

recensere

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