Peak-to-trough methods of calculation and data source

DRUG METHOD OF CALCULATION AND DATA SOURCE
LAI medications
Haloperidol decanoate Derived from the reported dose-normalized Cmax and Cmin19
Olanzapine pamoate Reported in the literature20
Paliperidone palmitate Predicted median Cmax and median Cmin in a PK model21
Risperidone LAI PK model22
Zuclopenthixol decanoate Reported in the literature14
Oral medications
Haloperidol Calculated from Cmax and Cmin in the literature19
Olanzapine Derived from graph depicting steady-state PK23
Paliperidone ER Calculated from the steady-state mean Cmax and Cmin in a PK study24,25
Risperidone Calculated from the average peak-to-trough fluctuation of the active moiety derived from a PK study and predicted from a PK model22,24

LAI: long-acting injectable; Cmax: maximum plasma concentration; Cmin: minimum plasma concentration; ER: extended release; PK: pharmacokinetics.
