Inclusion Criteria:

  1. Adults 18 and older who are patients at the Albany Medical Center Internal Medicine and Pediatrics practice (study site).
  2. Clinical diagnosis of acute bacterial sinusitis in accordance with the guidelines of the Infectious Disease Society of America (fitting into one of 3 categories: persistent sinus symptoms for 10 days or more; severe sinus symptoms for 3 days or more; or worsening sinus symptoms after initial improvement (double sickening).

Outcomes

Primary Outcome Measures

Number of Participants With a Global Rating of Improvement of 5 & 6 at the End of 3 Days of Treatment
Rating on a scale of 1=a lot worse, 2=a little worse, 3=the same, 4=a little better, 5=a lot better, 6=no symptoms, with a higher score indicating greater improvement.

Secondary Outcome Measures

Number of Participants With a Global Rating of Improvement of 5 or 6 at End of 10 Days Since Enrollment
Rating of 5 (a lot better) or 6 (no symptoms) on Global Rating of Improvement scale, with range of 1 (a lot worse) to 6 (no symptoms), with a higher score indicating greater improvement
Change From Baseline in the Total Score on the Sinonasal Outcome Test-16 (SNOT-16) at the End of 3 Days of Treatment
The change between enrollment and the end of 3 days of treatment in the total score on the Sinonasal Outcome Test-16 (SNOT-16). The total SNOT-16 is the sum of the participant's ratings of 16 symptoms of illness on the scale of 0 (no problem) to 3 (severe problem), with a possible range of 0 to 48, with a higher sum indicating more troubling symptoms. A decrease in total score would indicate an improvement in symptoms.
Change From Baseline in the Total Score on the Sinonasal Outcome Test-16 (SNOT-16) at the End of 10 Days Since Enrollment
The change between enrollment and the end of 10 days since enrollment in the total score on the Sinonasal Outcome Test-16 (SNOT-16). The total SNOT-16 is the sum of the participant's ratings of 16 symptoms of illness on the scale of 0 (no problem) to 3 (severe problem), with a possible range of 0 to 48, with a higher sum indicating more troubling symptoms. A decrease in total score would indicate an improvement in symptoms.
Balance of Benefits and Detriments
Assessment of balance between good effects and bad effects of antibiotic on scale of -3=bad effects much greater than good effects to +3=good effects much greater than bad effects
Number of Participants Answering "Yes" to Willingness to Take the Antibiotic Again in the Future
Response of "yes" at the end of 10 days since enrollment to the question whether the participant would take this antibiotic again, with possible answers of yes, no, or uncertain.

5. Study Description

Brief Summary
Comparative-effectiveness study of the treatment of acute bacterial sinusitis with amoxicillin/clavulanate 875mg/125mg bid for 7 days with or without the addition of immediate-release amoxicillin 875 mg bid x 7 days. .
Detailed Description
Double-blind comparative-effectiveness study of the treatment of acute bacterial sinusitis with standard dose of amoxicillin/clavulanate 875mg/125mg bid for 7 days, as recommended by the Infectious Disease Society of America, with or without the addition of immediate-release amoxicillin 875 mg bid x 7 days. The study aims are 1) to confirm, or not, our recent findings of more rapid improvement in overall symptoms with the additional amoxicillin, but also of more frequent diarrhea and vaginal yeast infections and 2) to assess, from the participants' point of view, the balance between improvement and adverse effects.

Phase 4
Interventional Study Model
Parallel Assignment
Model Description
Ill adult patients coming to a primary care office will be diagnosed by the treating physicians with acute bacterial sinusitis in accordance with the guidelines of the Infectious Disease Society of America. If they do not meet exclusion criteria, they will be offered enrollment in the study. If they agree, they will be provided unlabeled study medication, either amoxicillin/clavulanate 875/125 + placebo pills bid x 7 days (standard dose) or amoxicillin/clavulanate 875/125 + amoxicillin immediate-release 875 (high dose). Outcomes will be assessed, by telephone or over the web (through Qualtrics), at 3 and 10 days after enrollment.
Masking

Masking Description
Unlabeled bottles of study medications, identified only by participant #, prepared by the pharmacist member of research team. The placebo will be similar in appearance to plain amoxicillin. The pills inside the bottle will be difficult to see until the bottle is opened by the patient.
