The Challenge of New Drug Development

Why It's Difficult:

  • Time: 10-15 years from discovery to market
  • Cost: Can cost over $1 billion to develop one new antibiotic
  • Safety testing: Extensive clinical trials required
  • Regulatory approval: Strict requirements from health authorities
  • Limited profit: Antibiotics used for short periods unlike chronic disease drugs
  • Rapid resistance: Bacteria can develop resistance quickly

Alternative Approaches:

  • Bacteriophages: Viruses that specifically kill bacteria
  • Immunotherapy: Boosting immune system to fight infections
  • Antimicrobial peptides: Natural defense molecules
  • Combination therapies: Using multiple drugs together
  • Targeting virulence: Making bacteria less harmful without killing them
