Also known as:  Duricef.


Cedrox (formerly trademarked as Duricef) is a broad-spectrum antibiotic of the cephalosporin type, effective in Gram-positive and Gram-negative bacterial infections. It is a bactericidal antibiotic.

Cedrox is a first-generation cephalosporin antibacterial drug that is the para-hydroxy derivative of cefalexin, and is used similarly in the treatment of mild to moderate susceptible infections such as the bacterium Streptococcus pyogenes, causing the disease popularly called strep throat or streptococcal tonsillitis, urinary tract infection, reproductive tract infection, and skin infections.


For urinary tract infections, the recommended daily dosage for children is 30 mg/kg/day in divided doses every 12 hours. For pharyngitis, tonsillitis, and impetigo, the recommended daily dosage for children is 30 mg/kg/day in a single dose or in equally divided doses every 12 hours. For other skin and skin structure infections, the recommended daily dosage is 30 mg/kg/day in equally divided doses every 12 hours. In the treatment of beta-hemolytic streptococcal infections, a therapeutic dosage of Cedrox should be administered for at least 10 days.

In patients with renal impairment, the dosage of cefadroxil monohydrate should be adjusted according to creatinine clearance rates to prevent drug accumulation. The following schedule is suggested. In adults, the initial dose is 1000 mg of Cedrox and the maintenance dose (based on the creatinine clearance rate [mL/min/1.73 M2]) is 500 mg at the time intervals listed below.

Patients with creatinine clearance rates over 50 mL/min may be treated as if they were patients having normal renal function.


If the patient misses a dose, the dose should be taken as soon as it is remembered. Doses thereafter should then be evenly spaced with approximately 4-6 hours between doses, depending on the prescription dosing. Patients should not make up a missed dose by doubling up on their medication. Taking double doses will not speed recovery time, either. Taking doses close together or self administering a double dose is likely to cause an overdose which may lead to other health complications. An overdose may cause nausea, vomiting, diarrhea, dehydration, and abdominal cramps and requires immediate medical assessment.


Store at room temperature between 15 and 30 degrees C (59 and 86 degrees F) away from moisture and heat. Throw the medicine away after the expiration date. Keep out of the reach of children.

A reversed-phase column liquid chromatographic method was developed for the assay of cefadroxil in bulk drugs and pharmaceutical preparations. An equation was derived showing a linear relationship between peak-area ratios of cefadroxil to dimethylphthalate (internal standard) and the cefadroxil concentration over a range of 0.02-0.8 mg/ml (r = 0.9999). Standard addition recoveries were generally greater than 97.7%. The coefficients of variation in the within-day assay were between 0.36 and 0.65, and in the between-day assay was 0.71%. The column liquid chromatographic assay results were compared with those obtained from a microbiological assay, which indicated that the proposed method is a suitable substitute for the microbiological method for potency assays and stability studies of cefadroxil preparations.

Beta-streptococci isolated from patients with acute tonsillitis were tested for penicillin tolerance defined as an MBC/MIC ratio greater than or equal to 16. 11/18 strains recovered from patients with clinical treatment failure were tolerant to penicillin in comparison with 0/15 strains from successfully treated patients. The MBC/MIC ratio was less than 16 for all strains versus cefadroxil but above that ratio for many strains versus clindamycin, doxycycline and erythromycin. We suggest that penicillin tolerance may be one reason to treatment failures in individuals with streptococcal tonsillitis and that other antibiotics could be used to treat these patients since penicillin tolerance is not correlated to a general increase in antibiotic resistance.

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, 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.

In order to compare the clinical efficacy and safety of cefatrizine (Cefaperos) and cefpodoxime proxetil (Orelox) in the treatment of secondarily infected chronic obstructive pulmonary disease (COPD) in adults, a multicentre, randomized, open study was conducted by 60 general practitioners in two parallel groups of patient suffering from COPD complicated by an acute episode of superinfection (Anthoniesen stages 2 and 3). After verification of the eligibility criteria, written consent and randomization, the patients received, for 10 days, either cefatrizine at the dose of 1 g/day or cefpodoxime proxetil at the dose of 400 mg/day. A self-assessment form was given to the patient. A telephone visit was planned for D3. The final visit on D11 +/- 1 evaluated clinical efficacy (success or failure) and safety. The study population was composed of 250 patients with a mean age of 59.9 +/- 15.9 years (sex ratio M/F = 1.5). The principal etiology of COPD was chronic bronchitis in 67.5% of patients, longstanding asthma in 24.5% and emphysema in 6.8%. The mean history of the disease was 13.0 +/- 10.8 years. The Anthoniesen score was equal to 2 in 73.6% of patients, 3 in 8.8% of patients and 1 in 17.6% of patients. No significant difference concerning these criteria was observed between the two study groups. The clinical success rate was equivalent in the two groups. The time to regression of clinical signs tended to be shorter, up until the sixth day (mainly between D4 and D6) for patients treated with cefatrizine (p = 0.09; NS). The clinical safety was considered to be good and was comparable in the two study groups. This study concluded on the equivalent clinical efficacy of cefatrizine and cefpodoxime proxetil in the treatment of superinfections of COPD in general practice (97.5% and 99%, respectively), with a satisfactory and comparable safety, but with a much lower cost of treatment for cefatrizine. This conclusion is particularly important in the context of opposable medical references, as, although the treatment of superinfections of COPD by second and third generation cephalosporins is frequently proposed, the prescription of a less expensive cephalosporin appears to be more relevant.

A pathogenetic bacterial strain X-1-06909 was isolated from naturally infected Siberian sturgeon in Beijing. The strain was identified according to its physiological and biochemical properties, and the sequence analysis of 16S rRNA gene. The drugs sensitivity was detected with Kirby-Bauer's agar diffusion method.

A total of 410 strains of viridans group streptococci isolated consecutively from blood were tested by the microdilution method for in vitro susceptibility to 22 beta-lactam antibiotics. One hundred thirty-eight strains (33.6%) were resistant to penicillin with a MIC range of 0.25 to 8 micrograms/ml. MICs of all beta-lactam agents tested were higher for penicillin-resistant strains than for susceptible strains. These antibiotics were classified into three groups according to their in vitro activities (MICs at which 50 and 90% of the isolates are inhibited). Beta-Lactams of the first group (these included imipenem, cefpirome, FK-037, cefditoren, cefotaxime, ceftriaxone, and cefepime) showed activities higher than or similar to that of penicillin against penicillin-resistant viridans group streptococci. However, 80% of highly penicillin-resistant Streptococcus mitis organisms required cefotaxime and ceftriaxone MICs of > or = 2 micrograms/ml (range, 2 to 16 micrograms/ml). Beta-Lactams of the second group (cefpodoxime, ampicillin, amoxicillin-clavulanate, piperacillin, and cefuroxime) showed lower activities than penicillin. Finally, antibiotics of the third group (cephalothin, oxacillin, ceftazidime, cefixime, cefaclor, cefetamet, cefadroxil, cephalexin, and ceftibuten) showed poor in vitro activities. Therefore, some of the beta-lactam agents included in the first group could be an acceptable alternative in the treatment of serious infections due to strains highly resistant to penicillin, although clinical experience is needed.

The susceptibility of 2196 fresh clinical isolates to twelve different oral compounds was assessed in five Swiss microbiology institutions during summer 1992. A standardized microdilution system including all other material necessary was employed to assess the antibacterial activity of penicillin G, ampicillin, ampicillin + sulbactam, amoxycillin + clavulanic acid, cefadroxil, cephalexin, cefaclor, cefuroxime, cefetamet, doxycycline, erythromycin and clindamycin. The aminopenicillins (including the beta-lactamase inhibitor combinations) were highly active against the streptococci, in combination with a beta-lactamase inhibitor they covered the majority of the bla+ E. coli and Proteus mirabilis and between 60 to 80% of the Klebsiella spp. and Proteus vulgaris isolates. All the cephalosporins exhibited good activity against the streptococci, they were active against Gram-negative fermentative rods to a varying degree. Cefetamet was also active against many cefaclor and cefuroxime-resistant isolates. A considerable part of the species studied exhibited resistance to doxycycline; the observed resistance of S. agalactia, P. mirabilis, and Morganella morganii agreed with previous findings. Most of the Streptococcus spp. were inhibited by erythromycin and clindamycin. There were only single penicillin resistant S. pneumoniae isolates in the five Swiss centers. Taking account of the above particulars the epidemiology of antimicrobial resistance in Switzerland can be considered satisfactory.

A literature search was conducted of the Cochrane Library, EMBASE, and MEDLINE databases, from their inception through July 20, 2009, using the following terms: linezolid, newborn, infant, child, pediatrics, adolescent, human, clinical trial, and case report. Articles were excluded if they were redundant or not pertinent. (Articles that did not focus on the use of linezolid in children were considered not pertinent.) Bibliographies of all relevant articles were also evaluated.

In the 4 studies 958 patients were included in the intent-to-treat analysis. In the linezolid vs. cefadroxil study (Study III), the most common AEs in patients treated with linezolid were diarrhea (7.8%), headache (6.5%) and upper respiratory tract infection (3.7%). In the linezolid vs. vancomycin study (Study IV), the most common AEs in the linezolid group were fever (14.1%), diarrhea (10.8%) and vomiting (9.4%). The most common drug-related AEs for linezolid in all 4 studies were diarrhea, vomiting, loose stools and nausea. None of these common AEs or drug-related AEs occurred more frequently in patients treated with linezolid than in those in the comparator group.

The presence of a proton-coupled electrogenic high-affinity peptide transporter in the apical membrane of tubular cells has been demonstrated by microperfusion studies and by use of brush border membrane vesicles. The transporter mediates tubular uptake of filtered di- and tripeptides and aminocephalosporin antibiotics. We have used expression cloning in Xenopus laevis oocytes for identification and characterization of the renal high-affinity peptide transporter. Injection of poly(A)+ RNA isolated from rabbit kidney cortex into oocytes resulted in expression of a pH-dependent transport activity for the aminocephalosporin antibiotic cefadroxil. After size fractionation of poly(A)+ RNA the transport activity was identified in the 3.0- to 5.0-kb fractions, which were used for construction of a cDNA library. The library was screened for expression of cefadroxil transport after injection of complementary RNA synthesized in vitro from different pools of clones. A single clone (rPepT2) was isolated that stimulated cefadroxil uptake into oocytes approximately 70-fold at a pH of 6.0. Kinetic analysis of cefadroxil uptake expressed by the transporter's complementary RNA showed a single saturable high-affinity transport system shared by dipeptides, tripeptides, and selected amino-beta-lactam antibiotics. Electrophysiological studies established that the transport activity is electrogenic and affected by membrane potential. Sequencing of the cDNA predicts a protein of 729 amino acids with 12 membrane-spanning domains. Although there is a significant amino acid sequence identity (47%) to the recently cloned peptide transporters from Azithromycin Drug Side Effects rabbit and human small intestine, the renal transporter shows distinct structural and functional differences.

The purpose of this study was to compare the bacteriologic and clinical efficacy of oral cephalexin twice vs. three times daily vs. cefadroxil once daily as therapy for group A beta-hemolytic streptococcal (GABHS) tonsillopharyngitis. A prospective open-label, observational cohort study was conducted over 18 months (January 2000-June 2001). Children enrolled had an acute onset of symptoms and signs of a tonsillopharyngeal illness and a laboratory-documented GABHS infection. Follow-up examination and laboratory testing occurred 21 +/- 4 days following enrollment. Two hundred seventy-one patients were enrolled (intent to treat group): 63 received cephalexin twice daily, 124 received cephalexin three times daily, and 84 received cefadroxil once daily. Fifty-three children did not return for the follow-up visit, leaving 218 patients in the per-protocol group: 54 cephalexin twice-daily treated, 94 cephalexin 3-times daily treated, and 70 cefadroxil once-daily treated. In the per-protocol group, bacteriologic cure for those treated with cephalexin twice daily was 87%, for cephalexin 3 times daily, it was 81% and for cefadroxil once daily it was 81% (p = 0.61). The clinical cure rate for cephalexin twice-daily treatment was 91%; for three-times daily, it was 86%; and for cefadroxil once daily, it was 84% (p = 0.56). Because treatment allocation was not randomized, logistic regression analysis was used to adjust for treatment group differences. Younger age of patient was significantly associated with bacteriologic (p = 0.04) and clinical (p = 0.01) failure independent of treatment group but in the adjusted logistic model no differences were found among the 3 treatment regimens. Cephalexin dosed twice daily or three times daily Cleocin Dose For Uti and cefadroxil dosed once daily appear equivalent in bacteriologic and clinical cure of GABHS tonsillopharyngitis.

Serratia marcescens is an unusual cause of community-acquired meningitis in adults. We report a case of S. marcescens meningitis occurring 29 years after a head injury and preceded by 3 years of intermittent nasal discharge of cerebrospinal fluid (CSF). One month before admission, the patient had received treatment with cefadroxil. This case illustrates the risk of Gram-negative bacillary meningitis in patients with a CSF leak when they are treated with antibiotics. When patients have a chronic clear nasal discharge, one should look for a past medical history of head injury before prescribing antibiotics. In the presence of a fistula, any antibiotherapy may lead to the selection of resistant organisms which may be difficult to treat. Due to the high risk of meningitis and the fact that spontaneous Pediamox Drug Study closure in delayed CSF rhinorrhoea is unlikely, surgical repair of any associated fistulae is mandatory.

Gestation was found to decrease substantially both cefatrizine oral bioavailability and maximum serum plasma concentration (42.8 and 44.5%, respectively) but increased elimination half-life. This effect can be attributed to a substantial increase of the apparent volume of distribution of cefatrizine in relation to a moderate increase of clearance that occurs during pregnancy. Fetal Evocs Levofloxacino 750 Mg serum cefatrizine levels were lower for the first few hours after administration and then exceeded the corresponding maternal ones.

Cefadroxil, a cephalosporin antibiotic, is a substrate for several membrane transporters including peptide transporter 2 (PEPT2), organic anion transporters (OATs), multidrug resistance-associated proteins (MRPs), and organic anion transporting polypeptides (OATPs). These transporters are expressed at the blood-brain barrier (BBB), blood-cerebrospinal fluid barrier (BCSFB), and/or brain cells. The effect of these transporters on cefadroxil distribution in brain is unknown, Azithromycin Greenstone Brand especially in the extracellular and intracellular fluids within brain.

Céfadroxil, a new semisynthetic oral cephalosporin, is absorbed similarly by fasted and non-fasted subjects, produces sustained serum levels and is eliminated at a relatively slow rate. These pharmacokinetic properties permit less frequent and more convenient dosage scheduling than cephalexin and cephradine and consequently greater patient compliance. Cefadroxil was evaluated for safety in 1051 patients and for efficacy in 1030 patients. Overall it achieved a 91.8% rate of clinical success resulting from 881 complete cures and sixty-five clinical cures. Among 363 patients with respiratory tract infections and 471 patients with genito-urinary tract infections, cefadroxil treatment produced 97.5% and 84.5% clinical success, respectively. In the remaining infectious diseases treated, cefadroxil Synclar Antibiotic therapy resulted in 99.0% clinical success. Cefadroxil eradicated 87% of 1110 pathogens isolated, among which the most predominant pathogens were Staphylococcus aureus, beta-haemolytic streptococci, Streptococcus pneumoniae, Escherichia coli and Proteus mirabilis. Drug-related side-effects were reported in 7.2% of the patients.

The aim of this study was to determine the efficacy of oral antibiotics in the treatment of severe infections in cirrhosis. Twenty-two patients (17 males, 5 females) with spontaneous bacteremia (n = 7) or bacterial peritonitis (n = 15) were treated with oral pefloxacin 400 mg per 24 hr alone (n = 1) or in combination with another oral antibiotic, trimethoprimsulfamethoxazole (n = 13), amoxicillin (n = 6), cefadroxil (n = 2), or metronidazole (n = 1). In patients with spontaneous bacteremia, all organisms were found to be sensitive to oral antibiotics, and a favorable response was elicited in 6 out of 7 (86 p. cent) within 3 days (mean) of treatment. In patients with spontaneous peritonitis, ascitic fluid cultures were positive in 11 cases, and organisms were sensitive to pefloxacin in 9 out of 11 cases. A favorable response was elicited in 13 out of 15 within 2 to 8 days of treatment. Fourteen patients died (64 p. cent), 3 of infection (bacteremia n = 1, peritonitis n = 2), and 11 patients of causes unrelated to infection, mainly variceal hemorrhage, hepatorenal syndrome or hepatocellular carcinoma, although the clinical symptoms of infection were controlled. One-year survival was 57 p. cent in patients with bacteremia and 33 p. cent in those with bacterial peritonitis. Oral treatment was well tolerated in all patients. We suggest that most bacteremia and spontaneous bacterial peritonitis in cirrhotic patients can be treated with oral antibiotics. In some patients, this may be accomplished on an out patient basis.

Cefadroxil is a new semisynthetic cephalosporin with a broad antibacterial spectrum and a high chemotherapeutic potential when administered orally. The inhibitory activity of this compound was similar to that of cephalexin and cephradine when tested against 602 clinical isolates on Mueller-Hinton medium. In the oral treatment of experimental infections of mice, cefadroxil was more effective than cephalexin against Streptococcus pyogenes, and comparably effective against Streptococcus pneumoniae, Staphylococcus aureus, and several gram-negative species. Administered orally to mice, at doses ranging from 25 to 100 mg/kg, cefadroxil attained peak concentrations in the blood similar to those of cephalexin. At a dose of 200 mg/kg, however, higher peak levels were noted with cefadroxil than with cephalexin. In regard to other properties which were investigated, the behavior of cefadroxil compared favorably to that of cephalexin.

The cases of nineteen patients with sternocostoclavicular hyperostosis were reviewed retrospectively. Of particular interest were the responses to antibiotics and prostaglandin inhibitors. The prostaglandin inhibitors relieved the pain within three to four weeks in sixteen of eighteen patients so treated. However, the inhibitors gradually became less effective in most patients. Oral antibiotics were more effective than the inhibitors in relieving the pain of eight of the eleven patients who were given antibiotics. Pustulosis palmaris and plantaris, commonly associated with sternocostoclavicular hyperostosis, diminished after antibiotic therapy, as did the chest pain in most patients. The similarities between the age and sex distributions and the responses to antibiotics of the patients with sternocostoclavicular hyperostosis and those with pustulosis suggest that these disorders have a common etiology, and that the pustulosis may be a so-called bacterid reaction and the hyperostosis, a manifestation of a systemic reaction to a focal infection.
