• Safety profile consistent with inhaled aminoglycosides
• Patient preference for inhalation route

Barriers

• High treatment costs
• Need for specialized administration (nebulization)
• Limited awareness in some regions

5. Pricing Trends and Revenue Generation

Pricing Evolution

Year	Approximate Per-Vial Price (USD)	Treatment Schedule	Estimated Annual Cost for Patient*
2018	$3,350 per vial	590 mg twice daily (per month)	~$40,000
