Study Overview
=================
Brief Summary
-----------------
To evaluate the bioequivalence of one extended release combination (loratadine 5 mg/pseudoephedrine sulfate 120 mg) tablet manufactured for Bayer HealthCare LLC by SAG Manufacturing, S.L.U. Madrid, Spain (test treatment) to the extended release combination (loratadine 5 mg/pseudoephedrine sulfate 120 mg) tablet manufactured for Bayer SA-NV by Schering- Plough Labo NV Heist (reference treatment) which is currently marketed in Europe.
