(AZTREONAM) 

DESCRIPTION 
AZACTAM is a totally synthetic bactericidal antibiotic classified as
a monobactam. It 
has activity against a wide spectrum of gram-negative aerobic
pathogens. 
The monobactams, having a unique
monocyclic beta-lactam nucleus, are structurally 
different from other beta-lactam antibiotics (e.g.,
penicillins, cephalosporins, 
cephamycins, carbapenems). The sulfonic acid substituent in the
1-position of the ring 
activates the beta-lactam moiety; an aminothiazolyl oxime side
chain in the 3-position 
and a methyl group in the 4-position confer the specific
antibacterial spectrum and beta-
lactamase stability. 
Aztreonam is designated
chemically as (Z)-2-[[[(2-amino-4-thiazolyl)[[(2S,-3S)-2-
methyl-4-oxo-1-sulfo-3-azetidinyl]carbamoyl]methylene]amino]oxy]-2-methylpropionic 
acid. The structural formula is:

CLINICAL PHARMACOLOGY 
_Adult Pharmacokinetics _
Single 30 minute intravenous infusions of 500 mg, 1 g and 2 g doses
of AZACTAM  in 
healthy subjects produced peak serum levels of 54, 90, and 204
µg/mL, respectively, 
immediately after administration; at eight hours, serum levels were
1, 3, and 6 µg/mL, 
respectively (Figure 1). Single 3-minute intravenous injections
of the same doses resulted

in serum levels of 58, 125 and 242 µg/mL at five minutes following
completion of 
injection. 
Serum concentrations of aztreonam in healthy subjects following
completion of single 
intramuscular injections of 500 mg and 1 g doses are depicted
in Figure 1; maximum 
serum concentrations occur at about one hour. After
identical single intravenous or 
intramuscular doses of AZACTAM, the serum concentrations of
aztreonam are 
comparable at one hour (1.5 hours from start of intravenous
infusion) with similar slopes 
of serum concentrations thereafter.
