Figure 4. Dose-dependent effects of cariprazine on cocaine self-administration in rats.
(A) The dose-dependent effects of cariprazine on cocaine self-administration (infusions). (B) Effects of cariprazine on inactive lever presses. (C) Representative cocaine self-administration (infusions) records, illustrating the typical extinction-like patterns of drug taking and drug seeking—lower doses of cariprazine (0.3 mg/kg) increased, while at higher doses it produced an initial burst-like drug infusions followed by cessation of drug self-administration. *p < 0.05, **p < 0.01, compared to vehicle (0 mg/kg).
