Primary Outcome Measures:
  • Area under the curve [ Time Frame: Pre-dose and 18 time points Post-dose will be carried out within a 75 day time frame ]

Enrollment: 36
Study Start Date: April 2013
Study Completion Date: February 2014
Primary Completion Date: February 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Risperidone ISM 50mg
Three different single doses will be evaluated
Drug: Risperidone ISM 50 mg
Risperidone ISM 75mg
Three different single doses will be evaluated
Drug: Risperidone ISM 75 mg
Risperidone ISM 100mg
Three different single doses will be evaluated

Detailed Description:

This clinical trial will try to characterize and document the pharmacokinetics of risperidone ISM in schizophrenic or schizoaffective patients after one intramuscular injection at different dose strengths.Likewise, the safety and tolerability of risperidone ISM will be evaluated in the above mentioned population.

Following confirmation of eligibility and a washout period for study-prohibited drugs, a total of 33 subjects will be randomized in a 1:1:1 ratio to receive a single intramuscular (IM) injection of one of the following dosages of study drug:

Group 1: 50 mg risperidone ISM Group 2: 75 mg risperidone ISM Group 3: 100 mg risperidone ISM Several blood samples for plasma pharmacokinetic (PK) assessments will be obtained pre-dose and post-dose. Safety assessments will be conducted at each pre-specified time points.
