A
  • Antibacterial resistance
  • High cost of research and development of new medicines
  • testing and safety
57
Q

why is antibacterial resistance a problem within the pharmaceutical industry?

A
  • eg MRSA (superbugs)
  • concern that antibiotic resistance could grow, so more bacteria become resistant to antibiotics; Many infections have been treated straightforwardly with antibiotics since the discovery of penicillin but superbugs could make these infections life threatening again.

  • Keyhole surgery uses microscopic camera - operations take place with just a small cut to allow the cameras to be inserted and the procedure to be completed -reduces risk of infection and speeds up recovery times.
62
Q

how have modern treatments improved?
