THERAPEUTIC
CLASSIFICATION
Antibiotic
ACTION
Imipenem exerts a bactericidal action by inhibiting cell wall
synthesis in aerobic and anaerobic
gram-positive and gram-negative bacteria.
IMIPENEM AND CILASTATIN FOR INJECTION, USP
(imipenem and cilastatin sodium) consists of
two components: (1) imipenem, a derivative of thienamycin, a
carbapenem antibiotic; and
(2)
cilastatin
sodium,
a
specific
inhibitor
of
dehydropeptidase-I
a
renal
enzyme
which
metabolizes and inactivates imipenem. Cilastatin blocks the metabolism
of imipenem in the
kidney, so that concomitant administration of imipenem and cilastatin
allows antibacterial levels
of imipenem to be attained in the urine.
Inhibition of cell-wall synthesis is
achieved in
gram-negative bacteria by the binding of
imipenem to penicillin binding proteins (PBPs). In the case of
_Escherichia coli _
and selected
strains of
_Pseudomonas aeruginosa_
, imipenem has been shown to have highest affinity for PBP-
2,
PBP-1a
and
PBP-1b,
with
lower
activity
against
PBP-3.
The
preferential
binding
of
imipenem on
PBP-2
and
PBP-1b
leads
to
direct
conversion
of
the
individual
cell
to
a
spheroplast resulting in rapid lysis and cell death without filament
formation. When imipenem
is removed prior to complete killing of gram-negative species, the
remaining viable cells
show a measurable lag, termed a "post-antibiotic effect" (PAE), prior
to resumption of new
growth.
INDICATIONS AND CLINICAL
USE
IMIPENEM AND CILASTATIN FOR INJECTION, USP
(imipenem and cilastatin sodium) may be
indicated in the treatment of serious infections when caused by
sensitive strains of bacteria.
