Study summary

The purpose of this study is to 1) evaluate the extent of absorption of a single dose of a pregabalin controlled release tablet with and without coadministration of erythromycin and 2) evaluate the safety and tolerability of a single dose of a pregabalin controlled release tablet with and without coadministration of erythromycin.

What researchers measure

Primary outcomes

  1. Area under the curve from 0 to infinity (AUCinf)

    Time frame: 3 days

  2. Peak concentrations (Cmax) for assessment of equivalence between controlled released (CR) alone and CR with erythromycin

    Time frame: 3 days

Secondary outcomes

  1. Number of Participants with Adverse Events as a Measure of Safety and Tolerability

    Time frame: 3 days
