Flomoxef Chemische Eigenschaften,Einsatz,Produktion Methoden
Beschreibung
Flomoxef sodium is a P-lactamase resistant oxacephalosporin. Its spectrum of activity is
similar to that of cefazolin and moxalactam, but with better efficacy against
Staphylococcus aureus and Bacteroides fragilis. Flomoxef is reported effective in the
treatment of post-operative, urinary tract and abdominal cavity infections.
Verwenden
Flomoxef is an oxacephem derived beta-lactam antibiotic that is particularly effective against gram-positive bacteria.
Antimicrobial activity
An oxa-cephem which differs from latamoxef in the side
chains carried at the 7-amino and C-3 positions, but which
retains the 7-methoxy group that confers β-lactamase stability.
The methyl group of the methylthiotetrazole side chain of
latamoxef has been modified to hydroxymethyl in an attempt
to avoid the undesirable side effects, while the side chain at
the 7-amino position is F2-CH-S-CH2-.
Activity is similar to that of latamoxef, but activity against
Staph. aureus is improved and it is claimed to be a poor inducer
of penicillin-binding protein 2′, which is associated with resistance
in methicillin-resistant strains.
Intravenous injection of 2 g achieves a peak plasma concentration
of around 50 mg/L, falling to 2.6 mg/L after 6 h.
The plasma half-life is about 50 min. It appears to be well distributed
and penetrates moderately well into lung, mucosal
tissue of the middle ear and bone.
Flomoxef does not seem to be prone to the effects on platelet
function of latamoxef and it has a less marked effect on
vitamin K metabolism. It does not cause a disulfiram-like
reaction with alcohol.
It is available in Japan, where it appears safe and effective
in a wide range of infections.
