AOM accounted for 5.8% of the 43 433 visits or 6.2 cases/week per pediatrician. Among 3141 evaluable AOM cases (mean age 16.7±8 months, peak incidence at 10 months), 99% had been vaccinated with PCV7 and 42.1% attended day care (DCC). Recurrent AOM comprised 24.5% of cases and 51% of children had received ATB in the last 3 months. At the time of diagnosis, 47.1% had fever≥38,5°C, 74.5% otalgia and 4.7% otorrhea. Febrile and painful AOM accounted for 29.5% of cases and cunjunctivitis-otitis syndrome for 18.2%. ATB was prescribed in 98.7% of cases (cefpodoxime proxetil, 59% and amoxicillin/clavulanate, 37%). The failure rate was 6.4% and failure risk was greater in children in DCC (OR=1.50, [1.10;2.05]), young age<18 months (OR=1.47, [1.06;2.04]) and history of recurrent AOM (OR=1.45, [1.02;2.06]).
cefobid drug interaction
Linezolid has good activity against gram-positive bacteria, particularly multidrug resistant strains of S. aureus (including GISA), Enterococcus faecium and E. faecalis (including VRE). In controlled clinical trials, linezolid was as effective as vancomycin in eradicating infections caused by methicillin-resistant Staphylococcus spp. and has demonstrated efficacy against infections caused by VRE. As the level of resistance to vancomycin increases among S. aureus and enterococci, linezolid is poised to play an important role in the management of serious gram-positive infections.

The clinical success rates at day 12-19 in the per-protocol population (primary analysis) were 92.3% (215/233) in the cefpodoxime-proxetil group and 93.6% (204/218) in the amoxicillin-clavulanic acid group. The 95% confidence interval of [6.5%; 3.9%] demonstrated that cefpodoxime-proxetil was not inferior to amoxicillin-clavulanic acid. Cure rates at follow-up (day 25-30) were 90.6% and 92.7%, respectively. Results were similar in the intent-to-treat population. Compliance was significantly better in the cefpodoxime-proxetil group (99.2% versus 95.5%; p=0.011). Tolerance was also significantly better: 1.2% (3/247) of cefpodoxime-proxetil patients reported a treatment-related adverse event, compared with 10.7% (26/244) in the amoxicillin-clavulanic acid group (p<0.001). Most events were gastrointestinal and of mild to moderate intensity.
cefobid renal dose
Application of the HPLC hyphenated techniques of LC-MS, LC-NMR and solvent-elimination LC-IR was demonstrated by the identification of the degradation products of a third generation cephalosporin antibiotic, cefpodoxime proxetil, in solid state, drug formulation and solution. Molecular weight and fragment information were obtained by LC-MS, and detailed structural information was confirmed by LC-NMR. Information on the carboxyl functional group obtained by solvent-elimination LC-IR was useful for confirmation of the ester hydrolysis. The degradation products were successfully identified without complicated isolation or purification processes.

It was found that the reduction of the cefpodoxime proxetil (CP) molecule is strongly influenced by the adsorption. The adsorptive properties of CP were investigated in order to achieve an increase sensitivity of its determination. Validated adsorptive stripping differential pulse voltammetry is applied for the determination of low concentration of CP at pH 3.5 and 9.0 where the best pronounced adsorption effects were observed. The linearity of the calibration curves were achieved from 1 x 10(-8) to 1 x 10(-7)M with limit of detection (LOD) of 6.3 x 10(-9) and 7.1 x 10(-9)M, and limit of quantification (LOQ) of 2.1 x 10(-8) and 2.3 x 10(-8)M, at pH 3.5 and 9.0, respectively. The proposed method was tested for CP determination in spiked urine samples, enabling determination of low concentrations of CP.

A simple, accurate, rapid and precise reversed-phase high-performance liquid chromatographic method has been developed and validated for simultaneous determination of cefpodoxime proxetil and dicloxacillin sodium in tablet. The chromatographic separation was carried out on kromasil C18 analytical column (250×4.6 mm; 5 μm) with a mixture of acetonitrile:methanol:trifloroacetic acid (0.001%) with pH 6.5 (30:50:20, v/v/v) as mobile phase; at a flow rate of 1.0 ml/min. UV detection was performed at 235 nm. The dicloxacillin sodium and cefpodoxime proxetil were eluted at 1.92 and 3.35 min, respectively. The peaks were eluted with better resolution. Calibration plots were linear over the concentration range 0.5-20 μg/ml for cefpodoxime proxetil (r(2)=0.9996) and 5-50 μg/ml for dicloxacillin sodium (r(2)=0.9987). The method was validated for accuracy, precision, linearity and specificity. The method was very sensitive with limit of detection 0.0726, 0.3685 μg/ml and limit of quantification 0.220, 1.116 μg/ml for cefpodoxime proxetil and dicloxacillin sodium, respectively. The high recovery and low relative standard deviation confirm the suitability of the method for routine determination of cefpodoxime proxetil and dicloxacillin sodium in bulk drug and tablet dosage form.
Pharmacokinetic, bacteriological and clinical studies on S-1108 were performed in children. The results were as follows: 1. A total of 11 patients were treated with S-1108. Each dose was 3 mg/kg, orally administered 3 times daily for 4-14 days. The clinical efficacies of S-1108 in 10 patients with bacterial infections (1 with bacteremia, 4 with pneumonia, 1 with acute maxillary sinusitis, 1 with scarlet fever and 2 with streptococcal pharyngitis) were evaluated as excellent in 8 patients and as good in 2 patients with an efficacy rate of 100%. Only one patient with staphylococcal scalded skin syndrome due to methicillin resistant Staphylococcus aureus (MRSA) who received gamma-globulin was not evaluated. Fourteen causative strains of 5 species were found in 10 patients. Three strains of Streptococcus pneumoniae out of 5, 2 of 3 Branhamella catarrhalis strains, none of Staphylococcus aureus and all 3 strains of Streptococcus pyogenes were eradicated. No adverse reaction was observed in any of the 11 patients. 2. MICs of S-1108 against 5 clinically isolated S. pneumoniae from cases of infections were examined. All of them were relatively highly resistant to penicillins. S-1108 was compared with cefteram pivoxil, cefpodoxime proxetil, cefaclor and cefixime, and it showed better antibacterial activity or than other cephems. 3. Double peaks were obtained in plasma levels of S-1108 orally administered at a dose of 3 mg/kg at 30 minutes after meal and were 1.03 microgram/ml and 0.74 microgram/ml at 1 and 4 hours after administration, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)
SNEDDS formulations led to improved oral bioavailability due to enhanced solubilization of selected drug.
Cefpodoxime proxetil (RU 51 807) is the oral prodrug of cefpodoxime (RU 51 763), a third generation cephalosporin. The antibacterial activity of cefpodoxime was compared with the activities of amoxicillin in combination with clavulanic acid (AUG), cefaclor (CCl), cefuroxime (CXM) and cefotaxime (CTX), against species of Enterobacteriaceae showing a resistance pattern against ampicillin (AMP), ticarcillin (TIC), cefalothin (CFT) and cefotaxime (CTX) respectively. For strains AMP and TIC R, CFT and CTX S, MICs 90% of cefpodoxime were 1 mg/l (E. coli), 0.5 (K. pneumoniae), 0.06 (P. mirabilis), 0.5 (Shigella sp.) and 1 (Salmonella sp.); they were 4 to 16 times as high for AUG -CCL -CXM and 4 to 16 times as low for CTX. For K. pneumoniae AMP and TIC R, CFT I/R and CTX S, similar résults were obsereved for the 5 beta-lactam antibiotics, but with an activity 10 times as low. Among the species AMP R, TIC S, CFT R and CTX S, cefpodoxime was active against P. rettgeri, P. stuartii, C. diversus, E. aerogenes and Y. enterocolitica (MICs 90% ranging from 2 to 4 mg/l; from 0.12 to 1 mg/l for CTX) and less active or inactive against P. vulgaris, E. cloacae, S. marcescens, M. morganii and E. coli (MICs 90% ranged from 16 to 32 mg/l; from 1 to 4 mg/l for CTX).(ABSTRACT TRUNCATED AT 250 WORDS)
