Our findings are consistent with those of Khanzode SD et al who performed the study in a slightly higher dose range, but do not match with the results of Kaygisiz et al which showed a negative response of nimodipine in combination with ziprasidone, an atypical antipsychotic and no antipsychotic effect of nimodipine alone. But the dose used in the latter study was 0.5 mg/kg, which may be the reason behind the non-congruence with our findings.
