1.3 Regulatory and Approval Trends
- FDA & EMA: Historically, NPB formulations were approved mainly as compounded drugs; no broad new drug applications (NDAs) have been submitted recently for new indications.
- Emerging Regulations: Increased scrutiny over compounded drugs' safety and stability has prompted industry interest in FDA-approved formulations, possibly integrating NPB in FDA-regulated topical products.
- Orphan and Special Designation: Some regional initiatives consider NPB in severe or drug-resistant infections, with limited regulatory incentives.
2. Market Analysis
2.1 Current Market Size
The global market for topical antibiotics, within which NPB is a component, is estimated at approximately $2.4 billion (2022), with Neomycin and Polymyxin B formulations accounting for roughly $350 million of that, predominantly in North America and Europe.
