cefdinir and Tonsillitis

The clinical efficacy and safety of clarithromycin (CAM) and cefdinir (CFDN) were evaluated in 65 pediatric outpatients with group A beta-hemolytic streptococcal tonsillopharyngitis. Treatment was "effective" or better in 26 (78.8%) children receiving CAM and in 27 (87.1%) receiving CFDN based on antigen clearance and the "Criteria for Evaluation in Clinical Trials of Antibacterial Agents in Children" proposed by Japan Society of Chemotherapy (p = NS). The causative organisms were eradicated in 94.7% and 93.8% of subjects in the CAM and CFDN groups, respectively (p = NS). Adverse drug reactions were limited to moderate diarrhea in one patient in each group, and subsided during treatment. Causative organisms exhibited good susceptibility to CAM and CFDN. These results suggest excellent efficacy, safety and usefulness of CAM and CFDN in the treatment of group A beta-hemolytic streptococcal tonsillopharyngitsis in children.

Patients with acute exacerbations of chronic bronchitis were treated with cefdinir 300 mg bd for 5 days or cefprozil 500 mg bd for 10 days in a prospective, randomized, double-blind, multicentre study. Of the 548 patients enrolled, 281 (51%) were evaluable. The clinical cure rates at the test-of-cure visit were 80% (114/142) and 72% (100/139) for the evaluable patients treated with cefdinir and cefprozil, respectively. Respiratory tract pathogens were isolated from 409 (75%) of 548 admission sputum specimens, with the predominant pathogens being Haemophilus parainfluenzae, Haemophilus influenzae, Staphylococcus aureus and Moraxella catarrhalis. The microbiological eradication rates at the test-of-cure visit were 81% (157 of 193 pathogens) and 84% (166 of 198 pathogens) for the evaluable patients treated with cefdinir and cefprozil, respectively. Adverse event rates while on treatment were equivalent between the two treatment groups. The incidence of diarrhoea during therapy was higher for patients treated with cefdinir (17%) than for patients treated with cefprozil (6%) (P < 0.01), but most cases were mild and did not lead to discontinuation of treatment. These results indicate that a 5 day regimen of cefdinir is as effective and safe in the treatment of patients with acute exacerbations of chronic bronchitis as a 10 day regimen of cefprozil.

Group A beta-hemolytic streptococcal (GABHS) tonsillopharyngitis continues to be a prevalent pediatric infectious disease that requires prompt treatment for relief of symptoms and to prevent complications.. To compare the efficacy/tolerability of cefdinir and penicillin V in the treatment of pediatric GABHS tonsillopharyngitis as demonstrated in two clinical trials of similar design.. Multicenter, randomized, investigator-blinded trials.. Children < or =12 years of age with sore throat, pharyngeal erythema and positive rapid streptococcal antigen test results.. In Study A patients took cefdinir 7 mg/kg twice daily or 14 mg/kg once daily or penicillin V 10 mg/kg 4 times daily (all regimens for 10 days). In Study B patients took cefdinir 7 mg/kg twice daily for 5 days or penicillin V 10 mg/kg 4 times daily for 10 days.. Clinical and microbiologic evaluations were conducted at multiple times during and after therapy.. Of 1274 patients 1122 were evaluable (679 patients received cefdinir; 443 received penicillin V). Clinical cure and microbiologic eradication rates were superior in the combined cefdinir treatment groups (94.9 and 92.7%, respectively), whether given once or twice daily for 10 days or twice daily for 5 days, compared with the penicillin treatment group (88.5 and 70.9%, respectively; P<0.001 for both). Adverse event rates were comparable in the 2 groups.. Cefdinir is a reliable and well-tolerated drug for the management of GABHS tonsillopharyngitis in children.

Cephalosporins were found to be more effective than penicillins in the eradication of group A beta-hemolytic streptococcal (GABHS) from tonsillar tissues. This study investigated the effect of amoxicillin and cefdinir therapies on the rate of eradication of GABHS from the tonsils of children with acute pharyngo-tonsillitis (PT).. Of 50 children suffering from PT 25 were treated with amoxicillin (40 mg/(kg d) or 250 mg every 8 h) and 25 with cefdinir (14 mg/(kg d) or 600 mg once a day) for 10 days. Pharyngo-tonsillar cultures were obtained from all children before treatment and on the 1st, 2nd, 3rd, 4th, 7th, and 12th days.. GABHS was eradicated more rapidly from children treated with cefdinir as compared to those receiving amoxicillin. A smaller number of patients with GABHS were found in those treated with cefdinir as compared to amoxicillin throughout the treatment period. Eradication of GABHS from 68% (8 of 25 patients) was noted in those treated with cefdinir after 2 days and those treated with amoxicillin after 4 days. The differences between the number of patients who had a bacteriological cure between those receiving cefdinir to those getting amoxicillin was statistical significant at day 4 (32% vs. 8%). At the end of therapy GABHS was recovered from 5 (20%) and 2 (8%) of the patients. The group that received cefdinir, had a more rapid reduction in fever on the first after initiation of therapy as compared to those receiving amoxicillin. The fever reduction in those receiving cefdinir occurred a day earlier than in those getting amoxicillin.. Fever was reduced and GABHS was eradicated more rapidly from children treated with cefdinir as compared to amoxicillin.

This pooled analysis compared the clinical cure and bacterial eradication rates achieved by cefdinir and penicillin in the treatment of group A beta-hemolytic streptococcal (GABHS) pharngotonsillitis.. Data from 4 multicenter, randomized, controlled, investigator-blinded trials, 2 in children receiving oral suspensions and 2 in adults receiving capsules/tablets, were pooled and analyzed in terms of clinical cure rates, microbiologic eradication rates, and adverse events.. A total of 2751 patients were enrolled (age <13 years, n = 1274; age > or =13 years, n = 1477). Patients were randomized to receive cefdinir once daily (n = 569) or twice daily (n = 1086) for 5 or 10 days, or penicillin 4 times daily (n = 1096) for 10 days. Of the 2751 patients enrolled, 2198 were evaluable for clinical and microbiologic outcomes. Compared with the 10-day penicillin regimens, the cefdinir regimens for 5 or 10 days produced higher clinical cure and microbiologic eradication rates. Combined clinical cure rates were significantly higher for cefdinir compared with penicillin (94% vs 83%, respectively; P < 0.001). Combined microbiologic eradication rates were also significantly higher for cefdinir compared with penicillin (92% vs 77%; P < 0.001). Both cefdinir and penicillin were well tolerated, as >98% of patients completed the course of therapy.. In this pooled analysis of data from 4 multicenter, randomized, controlled, investigator-blinded trials in children and adults, 5- and 10-day regimens of cefdinir achieved significantly higher clinical cure and microbiologic eradication rates compared with 10-day penicillin regimens in the treatment of GABHS pharyngotonsillitis.

Core tonsillar cultures were obtained from 40 children with recurrent tonsillitis treated with either penicillin or cefdinir. Group A beta-hemolytic streptococci were isolated from 11 penicillin- and 3 cefdinir-treated (P < 0.001) patients. beta-Lactamase producers were recovered from 17 penicillin- and 3 cefdinir-treated (P < 0.01) patients. Inhibiting alpha-hemolytic streptococci were isolated less often from penicillin-treated patients than from cefdinir-treated patients.

A total of 2865 strains of the causative organisms isolated from the patients with acute pharyngitis and tonsillitis at the primary medical institutions were used in this study. The MICs of levofloxacin (LVFX) and other oral antimicrobial drugs were determined and evaluated by the NCCLS guideline. LVFX, cefditoren (CDTR) and cefcapene (CFPN) were potently active against 773 isolates of Hemophilus influenzae, the MIC50S of LVFX being < or = 0.06 microgram/mL and also the same as the MIC90S of LVFX. LVFX was the most active against 496 isolates of Enterobacteriaceae. The MIC50S of LVFX were < or = 0.06 microgram/mL and were lower than those of CDTR, cefdinir (CFDN) and cefpodoxime (CPDX) (MIC50S: 0.5 microgram/mL). The MIC90S of these cephems were markedly higher than the respective MIC50S, whereas MIC50 of LVFX was 0.12 microgram/mL, only twice the MIC50. Against the majority of Streptococcus pyogenes (555 isolates) and Streptococcus spp. (495 isolates), CDTR, CFDN, CPDX and CFPN were highly active (MICs: < or = 0.06 microgram/mL), and clarithromycin (CAM) and azithromycin (AZM) were also active against these organisms (MICs: 0.12 to 0.25 microgram/mL). Against S. pneumoniae (92 isolates), CDTR and CFDN were active (MIC50S: 0.12 and 0.25 microgram/mL, respectively). However, the MIC90S of these drugs were 4-8 times the MIC50S. Against Moraxella (Branhamella) catarrhalis (454 isolates), LVFX was potently active, the MIC90 of LVFX being < or = 0.06 microgram/mL and MIC90S of the other cephems being 0.5 microgram/mL or more. When the susceptibility of these strains to LVFX was evaluated by the NCCLS guideline, about 3% of other Streptococcus spp. were resistant to the drug but no test strains resistant to LVFX were detected in H. influenzae, S. pyogenes or Enterobacteriaceae. On the other hand, the percentages of strains susceptible to the cephems tested were 60-90%, which were quite different according to kinds of drugs and species used. Furthermore, the strains of S. pneumoniae resistant to CFDN and CPDX, and those to CAM and AZM were 21-25% and 50% or more, respectively, whereas no LVFX-resistant strains were detected. The major pathogens isolated from patients with pharyngitis and tonsillitis in the primary institutions were highly susceptible to LVFX. These results suggest that LVFX is a useful drug which is potently active against the strains resistant to oral cephem and macrolide antibiotics.
