Betalactams Piperacillin
CAS number 9012-26-4
Piperacillin sodium is derived from
D(-)-α -aminobenzyl-penicillin.
The chemical name of piperacillin sodium is sodium
(2S,5R,6R)-6-[(R)-2-(4-ethyl-2,3-dioxo-1-piperazine-carboxamido)-2-phenylacetamido]-3,3-dimethyl-7-oxo-4-thia-1-azabicyclo[3.2.0]heptane-2-carboxylate.
The chemical formula is C23H26N5NaO7S and the molecular weight is 539.5.
Piperacillin-tazobactam is a beta-lactam/beta-lactamase
inhibitor combination with a broad spectrum of antibacterial activity
that includes Gram-positive and -negative aerobic and anaerobic
bacteria.
Piperacillin-tazobactam retains its in vitro activity against
broad-spectrum beta-lactamase-producing and some extended-spectrum beta-lactamase-producing
Enterobacteriaceae, but not against isolates of Gram-negative bacilli
harboring AmpC beta-lactamases.
Piperacillin-tazobactam has recently been reformulated to include
ethylenediaminetetraacetic acid and sodium citrate; this new formulation
has been shown to be compatible in vitro with the two aminoglycosides,
gentamicin and amikacin, allowing for simultaneous Y-site infusion, but
not with tobramycin. Multicenter, randomized, double-blinded clinical
trials have demonstrated piperacillin-tazobactam to be as clinically
effective as relevant comparator antibiotics.
Clinical trials have demonstrated piperacillin-tazobactam to be
effective for the treatment of patients with intra-abdominal infections,
skin and soft tissue infections, lower respiratory tract infections,
complicated urinary tract infections, gynecological infections and more
recently, febrile neutropenia. Piperacillin-tazobactam has an excellent
safety and tolerability profile and continues to be a reliable option
for the empiric treatment of moderate-to-severe infections in
hospitalized patients.
