Symptomatic patients who visited the outpatient department of hospitals and clinics or general physicians and had agreed to participate in this study were screened and enrolled into the study.

Enrollment: 552 patients

Sex: All

Ages: 18 to 82 years old

   • Acute Bronchitis
   • Upper Respiratory Tract Infections (URTI) such as naso-pharyngitis
   • Sinusitis

3. Females of child bearing potential:

   1. Must have used efficacious and reliable method of contraception during the entire duration of the study {e.g. double barrier methods (e.g., condom and spermicidal); intrauterine device (IUD) } or remained sexually inactive throughout the study*.
   2. Must have had a negative urine pregnancy test (UPT) at Screening/Baseline (test must have a sensitivity of at least 25 mIU/mL for HCG).

   • *Abstinence (sexually inactive) was not an acceptable form of contraception; however, abstinent female patients could have been admitted to the study if they agreed, and signed a statement to the effect, that upon becoming sexually active, they would use a condom with spermicide from that time through 30 days beyond completion of the study (Visit 2).
