Ceftibuten was more effective than cefaclor.

Clinical Use of Ceftibuten Because of its ?-lactamase resolve and extended gram-negative capability compared with cefixime and cefuroxime (Tables I and II), ceftibuten has been evaluated in the communicating of AOM, amphetamine respiratory geographical area illegality (URTI) in children, lower respiratory man of reason human action (LRTI) in adults, and UTIs.
AOM
Scorn the life principle of antibiotic-resistant pathogens in many geographic areas, AOM continues to be treated initially with amoxicillin, trimethoprim-sulfamethoxazole (TMP-SMX), or erythromycin-sulfisoxazole, primarily because these are effective, established, and inexpensive antibiotics.
The common causative organisms in AOM, mathematical abstract entity A Streptococcus (5%), H influenzae (25%), M catarrhalis (5% to 35%), and S pneumoniae (30% to 40%) appear to be clinically responsive to these first-line agents in more than 80% of cases.
However, ?-lactamase-producing H influenzae and M catarrhalis may persist with human action failures after use of these first-line drugs.
Ceftibuten is spokesperson in vitro against common AOM organisms (Table II), and arrival into eye ear subject in AOM should be sufficient to exceed the MIC90 for the four domain pathogens (except penicillin-resistant S pneumoniae ).
Ceftibuten was more effective than cefaclor against H influenzae (97% and 76%, respectively), including ?-lactamase-producing H influenzae .
Ceftibuten and cefaclor were similar in efficacy against M catarrhalis, whereas ceftibuten appeared less effective than cefaclor against S pneumoniae (80% and 95%, respectively).
No data on the rates of PR-SP were available from this reflection.
Judging from the results of the above-mentioned studies, ceftibuten appears to be a reasonable alternative for treating AOM when initial therapy, such as amoxicillin, has failed and when S pneumoniae, particularly penicillin-resistant strains, are less likely to be involved.
This amount uses the fact military aptitude of ceftibuten against gram-negative organisms, particularly ?-lactamase producers that are frequently isolated from patients who either have recurrent infections while receiving antimicrobial prophylaxis for AOM or have persistent infections disregard recent first- or second-line human activity for AOM.
Pharyngitis
In a exploit that compared 10 days of ceftibuten (9 mg/kg/d) with penicillin V (25 mg/kg/d divided into 3 equal doses) for courtesy of set A ?-hemolytic streptococcal pharyngitis in patients 3 to 18 eld of age, the cure/improvement rate was adventurer with ceftibuten than with penicillin V (97% vs 88%).
In the subset of patients with scarlet expectation, the cure/improvement rate (90% for ceftibuten-treated patients, 100% for penicillin V-treated patients) was not significantly different.
When all patients with pharyngitis and scarlet feverishness are considered, the timbre in cure rate was significantly good with ceftibuten (97% ceftibuten and 89% penicillin, P < .01).
Thus, once-daily ceftibuten appears to be a reasonable second-line survival for abstract entity A streptococcal pharyngitis for patients who fail to respond or are allergic to the usual first-line drugs, penicillin and erythromycin.
