Brief summary: The purposes of this study is to demonstrate the analgesic efficacy of flurbiprofen 8.75 mg lozenge compared to its vehicle lozenge and to demonstrate the safety of the flurbiprofen lozenge throughout the course of treating sore throat due to acute pharyngitis.


Eligibility criteria: Inclusion Criteria:

1. The patient has a complaint of sore throat.
