Many advances have recently been made in the development of chemotherapeuti
c agents for bacterial infections. As a consequence of problematic antimicr
obial-resistant bacteria, research is now directed towards narrow-spectrum
agents rather than broad-spectrum agents. Further, orally active agents hav
e always been desirable, but today's cost-saving environment, in line with
a desire to minimize treatment costs, values reduced administration costs a
nd keeping patients out of the hospital. There has been a recent increase i
n research into orally active antibacterial agents, such as carbapenems and
cephalosporins, and non-glycopeptide natural products.
