Cefditoren pivoxil Chemische Eigenschaften,Einsatz,Produktion Methoden
Beschreibung
Cefditoren pivoxil is an orally active third generation cephalosporin introduced in Japan as a treatment for a broad range of bacterial infections including
dermatological and other community acquired infections. Cefditoren pivoxil is
reported to have a broad spectrum of activity against both Gram-positive and Gramnegative
bacteria, more potent than many other existing agents of its class. In
particular, it shows the highest therapeutic activity against S. pneumoniae and S.
marcescens infections. It exhibits resistance to β-lactamase hydrolysis typical of
third generation cephalosporins. As a prodrug of cefditoren, it is readily absorbed
through GI tract and has low toxicity and side effects.
Chemische Eigenschaften
Off-White Powder
Verwenden
Cefditoren Pivoxil is an antibacterial and is a third generation cephalosporin.
Definition
ChEBI: The pivaloyloxymethyl ester prodrug of cefditoren.
Antimicrobial activity
It exhibits good activity against staphylococci, streptococci
(but not enterococci), H. influenzae and M. catarrhalis, including
β-lactamase-producing strains. Isolates of Str. pneumoniae
exhibiting reduced susceptibility to penicillin are less susceptible
(MIC 0.125–2 mg/L). Most enterobacteria, including
many Enterobacter, Citrobacter, Serratia and Proteus spp., are
susceptible. It is not active against Ps. aeruginosa, Sten. maltophilia
or atypical respiratory pathogens such as Chlamydophila
pneumoniae and M. pneumoniae. It is stable to staphylococcal
and common enterobacterial β-lactamases.
Pharmakokinetik
Oral absorption: c. 70%
C
max 200 mg oral: c. 1.8 mg/L after 1.5–3 h
Plasma half-life: 0.8–1.3 h
Volume of distribution: 9.3 L
Plasma protein binding: 88%
After oral administration the pivaloyl ester is rapidly cleaved
by esterases in the gut wall. Ingestion with food improves
the bioavailability. Plasma concentrations are raised in
elderly patients. There is no accumulation on repeated
dosing.
It is excreted unchanged in the urine with a half-life of
around 1.5 h, achieving a concentration of 150–200 mg/L
within 4 h. Dosage adjustment is recommended in patients
with deteriorating renal function.
Clinical Use
It has been advocated for community-acquired upper and
lower respiratory tract infections and skin infections.
Nebenwirkungen
In common with other pivoxil esters it may cause carnitine
deficiency. Other side effects are those common to cephalosporins,
mainly gastrointestinal disturbance.
