A Study to Compare Capillary and Venous Whole Blood and Plasma Concentrations of Five Antipsychotics

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to compare capillary (the smallest of a body's blood vessels) and venous whole blood and plasma concentrations of 5 antipsychotics after given of a single oral, immediate-release dose to healthy participants.

Detailed Description
-----------------
This is a randomized (the study drug is assigned by chance), open-label (all people know the identity of the intervention), parallel-group (each group of patients will be treated at the same time), single-center study. Participants will be randomly assigned to 1 of 5 cohorts (groups) defined by the antipsychotic drug (aripiprazole, quetiapine, olanzapine, risperidone or paliperidone). Antipsychotics are drugs that are helpful in the treatment of psychosis and have a capacity to ameliorate thought disorders. Participants will enter the investigational site in the morning of Day -1 and stay until the morning of Day 2. Participants will return to the study site for subsequent assessments as per study's schedule. The total study length for a participant is approximately 26 days, except for participants receiving aripiprazole for whom the total study length is approximately 39 days.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Cohort A: Aripiprazole<br> | Drug: Aripiprazole<br>* Type= exact number, unit= mg, number= 5, form= tablet, route= oral administration. A single oral dose of a 5-mg aripiprazole tablet will be administered after an overnight fast.<br>|
| Experimental: Cohort B: Quetiapine<br> | Drug: Quetiapine<br>* Type= exact number, unit= mg, number= 100, form= tablet, route= oral administration. A single oral dose of two 50-mg quetiapine tablets will be administered after an overnight fast.<br>|
| Experimental: Cohort C: Olanzapine<br> | Drug: Olanzapine<br>* Type= exact number, unit= mg, number= 5, form= tablet, route= oral administration. A single oral dose of a 5-mg olanzapine tablet will be administered after an overnight fast.<br>|
| Experimental: Cohort D: Risperidone<br> | Drug: Risperidone<br>* Type= exact number, unit= mg, number= 1, form= tablet, route= oral administration. A single oral dose of a 1-mg risperidone tablet will be administered after an overnight fast.<br>|
| Experimental: Cohort E: Paliperidone<br> | Drug: Paliperidone<br>* Type= exact number, unit= mg, number= 3, form= tablet, route= oral administration. A single oral dose of a 3-mg paliperidone tablet will be administered after an overnight fast.<br>|
