Market Drivers and Barriers
Drivers
- Rising antimicrobial resistance (AMR): WHO states AMR could cause 10 million deaths annually by 2050 if unaddressed (source: WHO, 2021).
- Limited pipeline for new antibiotics: Patents for existing drugs like POLYTRIM provide market protection temporarily.
- Increasing prevalence of resistant Gram-negative bacteria: Particularly Pseudomonas aeruginosa, Acinetobacter baumannii, E. coli.
- Government initiatives: Funding for critical antibiotics development (e.g., GAIN Act in the US).
Barriers
- Regulatory challenges: Stringent approval processes in US FDA, EMA.
- Side effect profile: Polymyxins have nephrotoxicity concerns, impacting safety perception.
- Price competition: Generics reduce profit margins, discouraging R&D investments.
- Limited awareness and prescribing: Due to toxicity, often reserved for resistant infections.

Regulatory and Patent Considerations
Regulatory Status:
- Polymyxin B approved in US (FDA), EU (EMA), and other jurisdictions for specific resistant infections.
- Trimethoprim marketed as a standalone or in combination for urinary tract infections.
Patent Status and Market Exclusivity:
- Most formulations are off-patent, leading to generic proliferation.
- Patent extensions are rare due to age; strategic patent filings may focus on novel formulations or delivery methods.
Policy Environment:
- WHO recommends judicious use of polymyxins due to toxicity (WHO Model List of Essential Medicines).
- National stewardship programs restrict widespread use to preserve efficacy.
