Vancomycin, is clearly the choice drug to treat methicillin-resistant
staphylococci infections, but slow response and therapeutic failure ha
ve been reported. The efficacy of vancomycin is not in proportion to t
he post-infusion concentration but to the lenght of time for which van
comycin concentration at the infection site is high enough to inhibit
the pathogen. Continuous infusion may be a better way of maximizing th
at time and thus, vancomycin efficacy. Continuous infusion of vancomyc
in has been used in various situations but the efficacy and tolerance
of continuous infusion have never been compared with those of conventi
onal discontinuous infusion. Recent pharmacokinetic studies and a case
-control study suggested that the efficacy of vancomycin may be improv
ed through continuous infusion. More recently, we carried out a prospe
ctive multicenter study to compare continuous and discontinuous infusi
on of vancomycin, demonstrating that for a comparable efficacy and tox
icity, continuous infusion was easier to adjust and more cost-efficien
t.
