cefoprox xp 500 mg
Our results show that treatment with cefpodoxime proxetil may be effective in reducing symptoms of recurrent pharyngotonsillitis and preventing recurrences without causing side effects or developing bacterial resistance.
To discuss the chemistry, pharmacokinetics, spectrum of activity, clinical trials, adverse effects, drug interactions, and dosage guidelines of cefpodoxime proxetil.
cefoprox cv 325 mg
We report a case of acute interstitial nephritis (AIN) and immune hemolytic anemia (IHA) associated with cefpodoxime therapy.
cefoprox cv 325 medicine
Urea as hydrotropic agent showed best aqueous solubility of cefpodoxime proxetil, which can be used as solubilizing agent. The proposed method is new, simple, safe, eco-friendly, economic, accurate, and cost-effective and can be successfully employed in routine analysis.
cefoprox 100 syrup dosage
A single dose of cefpodoxime proxetil oral suspension was administered (10 mg/kg) to each horse by use of a nasogastric tube. In 7- to 14-day-old foals, 5 additional doses were administered intragastrically at 12-hour intervals. The MIC of cefpodoxime for each of 173 bacterial isolates was determined by use of a commercially available test.
Children with acute infections were treated with cefpodoxime proxetil (CPDX-PR, CS-807), a new oral cephalosporin. 1. A girl of 4 years old, weighing 17 kg, and another girl of 12 years old, weighing 33 kg, were administered orally each 3 mg/kg of CPDX-PR. Blood levels of CPDX reached peaks of 1.39 and 2.26 micrograms/ml at 4 hours-post-dose, and T1/2's were 2.09 and 2.63 hours, respectively. Cumulative urinary recovery rates for 8 hours were 57.3 and 80.9%, respectively. 2. A total of 30 patients was treated with CPDX-PR. These patients included 10 with acute tonsillitis, 6 with acute bronchitis, 5 with bronchopneumonia, 2 with scarlet fever and 2 with urinary tract infections, and one each with acute pneumonia, acute otitis media, acute otitis media plus sweat gland abscess, staphylococcal scalded skin syndrome and acute lymphadenitis. The treatment was effective in 27 cases out of 29 (except one with an unknown response) with a clinical efficacy rate of 93.1%. 3. Bacteriological responses to CPDX-PR were as follows; eradication of pathogen in 7, and unknown in 2 out of 9 cases from whom pathogens had been isolated prior to the treatment. 4. As a side effect, diarrhea was observed in 1 patient, but it was possible to continue the treatment. With regard to laboratory tests, a slight elevation of GOT and slight elevations of GOT and GPT were found in 1 case each.
To improve the solubility, permeability and oral bioavailability of cefpodoxime proxetil, β-lactam antibiotic. It is BCS Class IV drug having solubility 400 µg/mL and 50% oral bioavailability.
Dry syrup and tablet of newly developed cefpodoxime proxetil (CS-807, CPDX-PR) was investigated in the departments of pediatrics of 17 institutes and their related hospitals. 1. Pharmacokinetics of CPDX-PR in pediatrics were investigated. Peak blood levels of CPDX at dose levels of 3 mg/kg and 6 mg/kg were 2.24 +/- 0.21 and 4.68 +/- 0.54 micrograms/ml, respectively, in fasting and 1.65 +/- 0.07 and 3.71 +/- 0.41 micrograms/ml, respectively, after meal. Urinary recovery rates in 6 hours were 31.2 +/- 2.2% of dose in average. 2. Clinical efficacies of CPDX-PR on various infectious diseases were studied in 748 cases. Clinical efficacy rate in 499 cases with causative bacteria isolated was 94.6%: efficacy rates for individual infections were 96.8% (120/124) for tonsillitis, 96.0% (96/100) for urinary tract infection, 93.5% (58/62) for pneumonia, 92.4% (61/66) for impetigo, 100% (32/32) for scarler fever and 93.2% for pharyngitis or laryngitis. Bacteriological eradication rate for Gram-positive organisms was 91.0% (244/268); and for Gram-negative organisms, 89.7% (210/234). The clinical efficacy rate for cases which were non-responsive to previous antibiotic therapy was 88.1% (74/84). 3. Side effects and clinical laboratory findings were investigated in 779 cases. Two each of vomiting, loose stool and rash, 10 of diarrhea and 1 of diarrhea associated with candidiasis were reported, but no serious side effects were noted. There was no serious laboratory test abnormality except slight elevations of eosinophile, platelet, transaminase or prolongation of prothrombin time, totalling 34 occurrences.
