Challenges in the Market

• Escalating Resistance to Last-Line Therapies Including Carbapenems and Colistin
  P. aeruginosa’s ability to resist even last-line antibiotics poses a severe challenge in USA. Resistance to carbapenems and colistin leaves limited treatment options for critical infections. Mutations affecting efflux pumps, porin channels, and enzyme production make therapy increasingly difficult. As last-line drugs lose effectiveness, treatment becomes costlier and more complex. Hospitals struggle to manage outbreaks associated with highly resistant strains. Addressing this issue requires coordinated efforts in stewardship, surveillance, and drug innovation.

• High Cost of Advanced Antibiotics and Limited Affordability in Low-Resource Regions
  Advanced drugs such as ceftolozane/tazobactam and ceftazidime/avibactam are significantly more expensive than traditional antibiotics.
