Chronic sinusitis is prolonged inflammation of the paranasal sinuses that persists for more than 12 weeks despite treatment. Intranasal corticosteroids are typically used for treatment, followed by antibiotics or allergy medications, such as antihistamines, decongestants, leukotriene inhibitors, and anti-inflammatory agents. Although chronic sinusitis is one of the more-prevalent chronic illnesses in the United States, not many treatment options are available. Because no antibiotics are currently approved by the FDA to treat chronic sinusitis, otolaryngologists often prescribe antibiotics off-label based primarily on historical practice.

The report answers key questions including:

  • What patient shares do key therapies and brands garner by line of therapy in newly diagnosed chronic sinusitis patients? What are the quarterly trends in prescribing among recently treated and newly diagnosed chronic sinusitis patients?
  • How has the amoxicillin-clavulanate combination been integrated into the treatment algorithm, and what is its source of business?
  • What percentage of chronic sinusitis patients receive drug therapy within one year of diagnosis, and how quickly? What percentage of patients progress to later lines of therapy within one year of diagnosis?
  • What percentage of chronic sinusitis patients are treated with monotherapy versus combination therapy? What are the most commonly used combinations?
  • What are the product-level compliance and persistency rates among drug-treated patients?
