Deciding whether an antibiotic is necessary, when to begin therapy and selecting an optimal drug is an everyday challenge in clinical practice. In vitro susceptibility testing which determines the minimum concentration necessary for a particular antibiotic to inhibit or kill most strains of a bacterial species and pharmacodynamic modeling are useful but have limitations. The need for antibiotic therapy for acute otitis media (AOM) has been recently questioned. However, explanations for uniformly positive results with many antibiotic and placebo comparative trials include overdiagnosis of AOM at study entry, inclusion of patients with mild or uncomplicated AOM and broad criteria for the definition of clinical success. Recurrent and persistent AOM does not have as favorable a natural history as uncomplicated AOM; children below 2 years of age benefit most from antibiotic therapy. Selecting the best choice among the many antibiotics that can be used to treat AOM has become more complex over the last decade due to escalating antibiotic resistance among the pathogens that cause this infection. Broader spectrum antibiotics such as cefdinir, the newly introduced third generation cephalosporin, have their most prominent use in the treatment of persistent and recurrent AOM. In the early 1950s and 1960s penicillin clearly was the best available agent for the treatment of group A streptococcal (GAS) infections. In the 1970s the situation began to change as cephalosporin antibiotics became available. Superior eradication rates with cephalosporins such as cefdinir have now been well-documented. The leading hypothesis to explain the widening gap in efficacy between penicillin and cephalosporins relates to two major concepts: the presence of copathogens and differential alteration of the normal microbial ecology in the throat as a consequence of the selected therapy. There are positive and negative consequences to early initiation of antibiotic therapy for GAS tonsillopharyngitis. Penicillin has persisting good efficacy in patients older than the age of 12 years and in those who have been ill for >2 days. Shortening therapy for GAS tonsillopharyngitis offers a therapeutic advantage. Cefpodoxime proxetil and cefdinir have a 5-day indication for the treatment of GAS tonsillopharyngitis. Antibiotics with lower side effect profile, infrequent dosing, good palatability in suspension formulation and efficacy with short duration of treatment may lead to better outcomes because noncompliance often results in failed therapy, persistence of infection and morbidity.

Cefpodoxime proxetil is an oral cephem antibiotic of a new ester type, developed by Sankyo Co., Ltd in Japan. It has a broad antibacterial spectrum, which includes Staphylococcus, and a long half-life, allowing twice-daily administration. In Japan, clinical studies on this drug were performed in various fields, including internal medicine, surgery, urology, otorhinolaryngology, and obstetrics and gynaecology. Good or excellent clinical responses were observed in 2275 of 2902 patients analysed, giving a 78.4% efficacy rate overall. Side effects occurred in 98 patients (2.7%); these were mainly gastrointestinal and included diarrhoea, nausea, and vomiting. Abnormal laboratory test results observed included increased AST in 2.8% (55 of 1973), increased ALT in 3.2% (63 of 1965), and eosinophilia in 2.4% (36 of 1521).

Bacteriological, pharmacokinetic and clinical studies on cefpodoxime proxetil (CPDX-PR, CS-807), a new oral cephem antibiotic, were carried out in the field of pediatrics. The results obtained are summarized as follows. 1. Antibacterial activities of R-3746 (Na-salt of cefpodoxime (CPDX] against clinically isolated strains of Streptococcus pneumoniae, Streptococcus pyogenes, Staphylococcus aureus, Enterococcus faecalis, Branhamella catarrhalis, Escherichia coli, Proteus mirabilis and Haemophilus influenzae were compared with those of cefaclor, cephalexin and cefadroxil. R-3746 is superior to other antibiotics against S. pneumoniae, S. pyogenes, B. catarrhalis and Gram-negative rods. 2. Serum concentrations of CPDX after administration of CPDX-PR at doses of 3 mg/kg (fasting), 6 mg/kg (non-fasting) and 6 mg/kg (fasting) were determined. Mean AUC (area under curve)'s of CPDX obtained were 9.60, 31.35 and 17.89 micrograms.hr/ml, respectively for the 3 dosages. The mean half-lives of CPDX were 3.35, 1.88 and 1.76 hours, respectively. The mean urinary recovery rate within 8 hours after administration of CPDX-PR at a dose of 3 mg/kg (fasting) was 39.2%. 3. CPDX-PR was administered to 37 pediatric patients with various bacterial infections (pyelonephritis 9, cystitis 4, pneumonia 7, acute bronchitis 3, otitis media 2, tonsillitis 10, subcutaneous abscess 1 and purulent lymphadenitis 1). The overall clinical efficacy rate was 91.9% and the overall bacteriological eradication rate was also 91.9%. 4. No adverse reactions were observed. Abnormal laboratory findings were moderate, eosinophilia in 2 and slight elevation of GOT and GPT in 1. The taste and the odor of the CPDX-PR preparation was sufficiently tolerable. From the above results we have concluded that CPDX-PR is a useful oral antibiotic in the treatment of bacterial infections in children.
Cefdinir (FK482), a new oral cephalosporin, displayed potent oral activity versus induced infections in mice. In studies using beta-lactamase-nonproducing (beta LAC-) and -producing (beta LAC+) Staphylococcus aureus strains, respective PD50s (in mg/kg) were 11 and 24 for preventing subcutaneous abscess and 2.7 and 2.3 for preventing lethal systemic infection. In studies using beta LAC- and beta LAC+ Haemophilus influenzae, respective PD50s were 5.8 and 3.1 for preventing lethal systemic infection. Time-kill studies versus H. influenzae showed that 6- to 12-mg/kg dosing was effective in reducing viable counts of these strains in blood by > or = 100-fold by 24 h after challenge. This in vivo performance was comparable to or exceeded values generated by cefaclor, cefpodoxime proxetil, and ampicillin.

Two accurate, precise, sensitive and economical procedures for simultaneous estimation of Cefpodoxime proxetil and Potassium clavulanate in tablet dosage form have been developed. The methods employed were absorbance correction method (I) and first order derivative spectroscopic method (II). The first method employs wavelength 288 nm for direct estimation of Cefpodoxime proxetil where Potassium clavulanate shows nil absorbance. Estimation of Potassium clavulanate is carried out after correction for absorbance of Cefpodoxime proxetil at 218 nm. The second method is based on first order derivative spectroscopy. Wavelengths 235.6 nm and 308.2 nm were selected for the estimation of the Potassium clavulanate and Cefpodoxime proxetil, respectively. Both the drugs obey Beer's law in the concentration range 5-50 microg/ml. The results of analysis have been validated statistically and by recovery studies. The percentage assay was found to be 99.54 +/- 0.285 for Cefpodoxime proxetil and 98.53 +/- 0.760 for Potassium clavulanate (Mean +/- SD) by method I and 99.93 +/- 0.270 for Cefpodoxime proxetil and 99.40 +/- 0.723 for Potassium clavulanate (Mean +/- S.D) by method II respectively.

This observational study was designed to assess the acceptability of oral antibiotics (including generics) commonly prescribed to children by primary care physicians in France. It was given to 50 pediatricians and 50 GPs in private practice. For each patient, the physician and parents completed a questionnaire, and parents filled out a log for each drug intake.
Pharmacokinetic and clinical evaluation of cefpodoxime proxetil (CPDX-PR, CS-807) were performed in the field of pediatrics. The obtained results are summarized as follows. 1. Peak serum concentrations of CPDX upon single oral doses of 3.0 mg/kg and 4.4 mg/kg of CPDX-PR were 1.26-1.46 micrograms/ml and 1.45 micrograms/ml, respectively, achieved at 4 hours and 1 hour after administration. Urinary excretion rates for CPDX in the first 8 hours ranged between 28.1 and 30.2%. 2. Clinical efficacy rates for pediatric infections obtained at single dose levels ranging 3 to 6 mg/kg were 97.5%, and that at a single dose of 1 mg/kg were 90.9%. 3. Bacteriological effectiveness was determined in 45 strains identified in recent cases. Eradication rates for these bacteria at dose levels of 3 to 6 mg/kg and 1 mg/kg were 91.3% and 95.5%, respectively. 4. No side effect nor abnormal laboratory test data were found in any of the cases examined. From these results, CPDX-PR appeared to be a useful antibiotic agent in the field of pediatrics.
