The aerobic and anaerobic flora from gingival pockets of 49 dogs with severe gingivitis and periodontitis were cultured. The susceptibility of each isolate to four antimicrobial agents currently approved for veterinary use in the USA (amoxicillin-clavulanic acid; clindamycin; cefadroxil; and enrofloxacin) was determined. Amoxicillin-clavulanic acid (Clavamox Pfizer Animal Health) had the highest in-vitro susceptibility against all isolates (96%), all aerobes (94%) and all anaerobes (100%) tested. For gram-negative aerobes, enrofloxacin (Baytril, Bayer Corp.) had the highest in-vitro susceptibility activity. For bacteria associated with treatment of gingivitis, which typically are mixed aerobic/anaerobic and gram-positive/gram-negative organisms, the antimicrobial of choice for clinical use based on these susceptibility tests is amoxicillin-clavulanic acid.

Data were obtained from two independent clinical trials. In an outpatient trial children (5 to 17 years of age) with uncomplicated skin and skin structure infections (SSSIs) were treated with linezolid or cefadroxil. In an inpatient trial hospitalized children (0 to 11 years of age) with pneumonia, bacteremia or complicated SSSI caused by resistant Gram-positive pathogens were administered iv linezolid with the option to switch to oral suspension (patients >90 days of age) or iv vancomycin. A subset of patients with MRSA infections from the two clinical trials is analyzed herein.

This randomized, blinded, comparator-controlled, multinational trial compared the efficacy and safety of linezolid and cefadroxil for treatment of uncomplicated skin/skin structure infections in pediatric patients. Children ages 5 to 11 years were to receive linezolid suspension [10 mg/kg (up to 600 mg)] or cefadroxil suspension [15 mg/kg (up to 500 mg)] every 12 h. Patients ages 12 to 17 years were to receive linezolid tablets (600 mg) or cefadroxil capsules (500 mg) every 12 h. Therapy lasted 10 to 21 consecutive days with a follow-up visit 10 to 21 days posttherapy.

An innovative, selective and rapid reversed phase High Performance Liquid Chromatographic (RP-HPLC) method for the analysis of cefadroxil in bulk material and oral solid dosage forms has been developed and validated. The chromatographic system consisted of Sil-20A auto sampler, LC-20A pump and SPD-20A UV/visible detector. The separation was achieved by C18 column at ambient temperature with a mobile phase consisting of methanol: Phosphate buffer (10: 90) at a flow rate of 1.5 ml/min. The method is reproducible, repeatable (%RSD for intra-day and inter-day ranged between 1.75-5.33% and 0.58-2.69%) and linear (R2=0.9935). The LOD and LOQ of the method were 0.5 and 1.0 μg/ml, respectively. The present RP-HPLC method was found to be sensitive, accurate, precise, rapid and cost effective that can be efficiently used in QC/QA laboratories for routine analysis of the raw materials as well as oral dosage formulations of cefadroxil.

Two different cefadroxil (CAS 50370-12-2) formulations were evaluated for their relative bioavailability in 24 healthy volunteers who received a single 500 mg oral dose of each preparation. An open, randomized clinical trial designed as a two-period crossover study with a 7-day washout period between doses was employed. Plasma samples for assessments of their cefadroxil concentration by HPLC-UV were obtained over 8 h after administration. Values of 48.94 +/- 10.18 pg x h/ml for test, and 48.51 +/- 9.02 microg x h/ml for the reference preparation AUC(0-t) demonstrate a nearly identical extend of drug absorption. Maximum plasma concentration Cmax of 16.04 +/- 4.94 microg/ml and 16.01 + 4.02 microg/ml achieved for the test and reference preparations did not differ significantly. The parametric 90% confidence intervals (CI) of the mean of the difference (test-reference) between log-transformed values of the two formulations were 96.80% to 104.51% and 92.01% to 107.00% for AUC(0-t) and Cmax, respectively. Since for both AUC(0-t) or Cmax the 90% CI values are within the interval proposed by the Food and Drug Administration, the test product is bioequivalent to the reference product for both the rate and extent of absorption after single dose administration.

A prospective, coordinated, randomized multicentre trial was conducted to determine whether tobramycin 160 mg intravenously (i.v.) once daily for 2 days would improve the efficacy of cefotaxime 1 g i.v. twice daily for 2 days followed by a 10-day course of oral cefadroxil 1 g twice daily, in the treatment of community-acquired acute pyelonephritis in women. Of 73 patients enrolled in the study, 51 could be evaluated according to the protocol. There were no significant differences in bacteriological cure rates between the combined treatment with tobramycin/cefotaxime and cefotaxime alone, either at short-term follow-up (63.0% vs 59.1%; 95% confidence interval (CI) for difference in proportions -23.4% to 31.2%), or up to 7 weeks after cessation of treatment (42.9% vs 52.2%; 95% CI, -18.0% to 36.6%). A modified intention-to-treat analysis showed no difference in clinical efficacy between the two regimens (68.6% vs 69.2%; 95% CI, -22.9% to 24.1%). Tobramycin seemed to enhance the resolution of inflammation by a more rapid decline in C-reactive protein levels. The high recurrence rates after treatment with beta-lactam antibiotics in this and previous studies of acute pyelonephritis may be explained by adverse ecological effects rather than failure to eradicate the infection.

The apparent functional molecular mass of the kidney peptide/H(+)-symporter was determined by radiation inactivation in brush-border membrane vesicles (BBMV) of rat kidney cortex. Purified BBMV were irradiated at low temperatures with high energy electrons generated by a 10-MeV linear accelerator at doses from 0 to 30 megarads. Uptake studies were performed with [3H]cefadroxil, a beta-lactam antibiotic which serves as a substrate for the kidney peptide/H(+)-symporter. Inhibition of influx of [3H]cefadroxil into BBMV was used to determine the functional molecular mass of the transporter. Additionally, direct photoaffinity labeling of the transport- and/or binding proteins for [3H]cefadroxil in control and irradiated BBMV was performed to determine the molecular mass of the putative transporter by SDS-polyacrylamide gel electrophoresis. Initial rates of pH-gradient dependent uptake of [3H]cefadroxil decreased progressively as a function of radiation dose. The apparent radiation inactivation size (RIS) of the transport function was found to be 414 +/- 16 kDa. Direct photoaffinity labeling yielded labeled membrane proteins with apparent molecular masses of 130 kDa and 105 kDa, respectively. The proteins displayed different labeling characteristics with respect to incubation time, specificity and the response to irradiation. It appears that only a 105 kDa protein is directly involved in transport function since (a) only it showed a specific pH gradient dependent labeling pattern and (b) the covalent incorporation of [3H]cefadroxil into this protein decreased parallel to the loss of transport function in irradiated BBMV. The peptide/H(+)-symporter in kidney brush-border membranes therefore appears to have a monomer mass of 105 kDa and may function in an oligomeric arrangement.

The bacterial flora in patients referred with chronic bacterial prostatitis were studied. Only 13% had Gram-negative bacteria in significant numbers but 43% had Gram-positives using the same criteria. Half of the patients were symptom-free by the end of a 12-week course of antibiotics and remained so after 6 months; in one-third the symptoms were unchanged 6 months after completing treatment. The relief of symptoms correlated with the disappearance of white blood cells in the expressed prostatic secretion (EPS) and with a lowered pH in the EPS. Thus only 1 of the 14 patients without symptoms at 6 months had a significant growth of bacteria at the prostatic level, whereas 7 of 10 patients with unchanged symptoms had a significant bacterial colonisation. Although the initially infecting organism was eliminated in about half of the patients, new Gram-positive bacteria were isolated after treatment in 13 of 29 patients; 12 of these resolved spontaneously within 6 months. Five patients with Gram-positive bacteria were colonised with new Gram-negatives at the end of treatment. Two healed spontaneously but 3 remained colonised with Gram-negatives at the end of the follow-up period. These findings make it likely that many patients infected with Gram-positive bacteria benefit from antibiotic treatment. However, disturbances in the bacterial flora by antibiotic treatment may facilitate invasion by new types of bacteria.

Over a 10-y period, patients hospitalized with Pasteurella-induced cat or dog bite-associated wound infection were analysed retrospectively with regard to preceding antibiotic medication. In 10/14 cases, hospitalization was necessitated in spite of prophylactic or therapeutic administration of oral antibiotics. In 1 case, phenoxymethylpenicillin and flucloxacillin had been prescribed. The other patients received flucloxacillin (7 patients), erythromycin, or cefadroxil (1 patient each), agents that are not consistently active against Pasteurella. In conclusion, hospitalization due to Pasteurella-induced animal bite-associated wound infection seemed to be related to the prescription of suboptimal oral antibiotic therapy at a preceding medical consultation.

The activity of the renal peptide transporters PEPT2 and PEPT1 determines-among other factors such as metabolic stability in liver and plasma-the circulatory half-life of penicillins and cephalosporins during therapy. This study was initiated to examine systematically the interaction of beta-lactam antibiotics with PEPT2. Interaction of 31 cephalosporins and penicillins with the carrier protein was characterized by measuring their ability to inhibit the uptake of [(14)C]Gly-Sar into renal SKPT cells. Cefadroxil, cefaclor, cyclacillin, cephradine, cephalexin and moxalactam were recognized by PEPT2 with very high affinity comparable to that of natural dipeptides (K(i)=3-100microM). Ceftibuten, dicloxacillin, amoxicillin, metampicillin, cloxacillin, ampicillin, cefixime, cefamandole, oxacillin and cefmetazole interacted with PEPT2 with medium affinity (K(i)=0.1-5mM). For the other beta-lactam antibiotics studied interaction was very low or not measurable (K(i)>5mM). The affinity constants of beta-lactam antibiotics at rPEPT2 and hPEPT1 are significantly correlated, but the rank orders are not Paracetamol 850 Mg identical. Decisive differences between PEPT1 and PEPT2 recognition of the N-terminal part of the compounds became evident. Moreover, this large data set of affinity constants of beta-lactam antibiotics will be useful for structure-transport (binding) analyses of PEPT2.

In the present study, both disintegrating and non-disintegrating polymeric capsular system in achieving delayed as well as improved osmotic flow for the model drug cefadroxil was developed. Asymmetric membrane in membrane capsule (AMMC) was prepared on a glass mold pin via phase inversion process in two steps. Step 1 included formation of a non-disintegrating, asymmetric membrane capsule (AMC) and step 2 involved formation of a pH sensitive, disintegrating, asymmetric membrane (AM) formed over the non-disintegrating membrane. The effects of different formulation variables were studied namely, level of osmogen, membrane thickness, and level of pore former. Effects of varying osmotic pressure, agitational intensity and intentional defect in the inner membrane on drug release were also studied. Membrane characterization by scanning electron microscopy showed Lipitor 50 Mg dense regions with less pores on the outer surface of the disintegrating membrane and porous regions on the inner surface of the non-disintegrating asymmetric membrane. In vitro release studies for all the prepared formulations were done (n=6). The drug release was independent of pH, agitational intensity and intentional defect on the membrane but dependent on the osmotic pressure of the dissolution medium. The release kinetics followed the zero order and the mechanism of release was Fickian diffusion.

Several bacteriological and serological variables were studied in connection with a clinical treatment trial in 212 patients with group A streptococcal pharyngotonsillitis. Anaerobic incubation was not superior to incubation in 5% CO2 in air for the detection of group A streptococci. Saliva cultures were inferior to conventional throat cultures in detecting group A streptococci. No strains from patients with recurrences were found to be tolerant to penicillin. In several patients (all asymptomatic), group C and G streptococci were found in follow-up cultures. Group A streptococci serology was more often Inderal La Medication positive after two months than after one month, also in patients without recurrence.

Cefatrizine, a new orally administered cephalosporin, was tested against 400 clinical isolates. Cefatrizine had excellent activity against gram-positive cocci, inhibiting all except enterococci at minimal inhibitory concentrations below 1 mug/ml. Cefatrizine inhibited the majority of Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, and Salmonella at concentrations below 12.5 mug/ml. Although cefatrizine was not hydrolyzed by many beta-lactamases, it did not inhibit a number Trental Drug Interactions of strains of Enterobacter, Serratia, or indole-positive Proteus. Cefatrizine was more active than cephalothin or cephalexin against E. coli, Klebsiella, Enterobacter, Citrobacter, Salmonella, and Shigella. Its overall activity was less than that of cefoxitin against strains resistant to cephalothin, but its activity against cephalothin-susceptible strains was equivalent to that of cefamandole.

The incidence of AAD in the probiotic group was 10.8% compared to 15.6% in the placebo group, the difference being statistically non-significant (p = 0.19). The relative risk for AAD was 0.7 with the 95% CI being 0.4 to 1.2. The diarrhoea duration in the probiotic group was two days with an interquartile range of 1- 3 days Cefixime 200mg Dosage and was significantly less (p = 0.01) than the placebo group which was four days with an interquartile range of 3 - 5.5 days. Subgroup analysis of subjects with AAD showed that the incidence of severe diarrhoea (watery stools) was 96% in the placebo group (25 out of 26) compared to 31.6% (6 out of 19) in the probiotic group and this difference was significant statistically (p < 0.001). Four mild, non-serious, adverse events were detected (2.0%) in the probiotic group but there were none in the placebo group.

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 Glucophage Drug Label 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.

The effect of human immunoglobulins (Ig) and of glycine, often added to commercial preparations as a stabilizer, have been examined in vitro on the growth of E. coli strains in the absence or presence of antibiotics in subminimal inhibitory concentrations (subMic). The Ig's (= 7S or 5S = F(ab')2 as well as glycine had no effect by themselves on bacterial growth at concentrations up to 32 mg and 4.5 mg per ml respectively. In contrast, in the presence of ampicillin, glycine induced a concentration dependent increase of bacterial sensitivity to antibiotics. This is apparently more pronounced in serosensitive than in seroresistant E. coli strains. Such a synergism could equally be shown with cefadroxil and fosfomycin, i.e. with other antibiotics interacting with cell wall synthesis, but not with those of another mode of action, as ciprofloxacin, polymyxin B or chloramphenicol.

In this study, we proposed a rapid and simple method for the preparation of molecularly imprinted polymers (MIPs) by emulsion polymerization. The polymerization process was accelerated by microwave heating, and the reaction time was greatly shortened. The obtained MIPs were spherical in shape and exhibited a uniform morphology. The MIPs with selectivity and high affinity to florfenicol were successfully applied as solid-phase extraction materials to extract and clean up the florfenicol in milk, followed by liquid chromatography-tandem mass spectrometry (LC-MS) analysis. The parameters affecting the performance of extraction and LC-MS analysis were evaluated. The detection limit of the method was 4.1ngmL(-1). The relative standard deviations of intra- and inter-day were in the range of 3.5-4.7% and 3.9-7.5%, respectively.

The degradation kinetics and mechanism of a new, orally effective cephalosporin derivative, cefadroxil, in aqueous solution were investigated at pH 2.51-11.5 at 35 degrees and ionic strength 0.5. The degradation rates were determined by high=pressure liquid chromatography. At constant pH and temperature, the degradation followed first-order kinetics and a log k-pH profile was presented. The shape of the rate-pH profile resembled that for cephalexin or cephradine under the same conditions. Citrate and phosphate buffers enhanced general acid and base catalysis of the degradation. In aqueous solution, cefadroxil was shown to degrade by three parallel reactions: (a) intramolecular aminolysis by the C-7 side-chain amino group on the beta-lactam moiety, (b) water-catalyzed or spontaneous hydrolysis, and (c) beta-lactam cleavage by the nucleophilic attack of hydroxide ion. In neutral and weak alkaline solutions, the main degradation products were two piperazine-2, 5-diones and 3-hydroxy-4-methyl-2(5H)-thiophenone, the former being formed from Reaction a, while the latter arose via the degradation pathways of Reaction b and/or c.

Streptococcal infection usually is defined as a positive throat culture with a serologic response to group A beta-hemolytic streptococci, and a patient with a positive throat culture and no serologic response is a streptococcal carrier. Studies suggest that streptococcal carriers should show little clinical response to antibiotic therapy when compared with patients with true streptococcal infections. Patients with acute pharyngitis were divided into three groups: group 1--38 patients with negative throat cultures; group 2--72 patients with a positive throat culture and a significant rise in streptococcal antibody titers; and group 3--77 patients with positive throat cultures and no significant rise in streptococcal antibody titers. Patients in group 2 and group 3 had a comparable and dramatic clinical response to antibiotic therapy that was considerably greater than the clinical response in the patients in group 1. These findings raise questions about the appropriateness of using streptococcal antibody responses to distinguish between the streptococcal carrier state and a true streptococcal infection.

Cephalosporin antibiotics are thought to be excreted into the urine via organic anion transporters (OATs) and OAT can mediate nephrotoxicity by cephalosporins, particularly by cephaloridine. The purpose of this study was to elucidate the interaction of human-OAT2 and rat-OAT2 with cephalosporin antibiotics using proximal tubule cells stably expressing human-OAT2 and rat-OAT2. Human-OAT2 is localized to the basolateral side of the proximal tubule, whereas rat-OAT2 is localized to the apical side of the proximal tubule. Cephalosporins tested were cephalothin, cefoperazone, cefazolin, ceftriaxone, cephaloridine, cefotaxime, cefadroxil and cefamandole. These cephalosporins dose-dependently inhibited organic anion uptake mediated by human-OAT2 and rat-OAT2. There was no species difference observed for the effects of OAT2 with cephalosporins between human and rat transporters. Kinetic analysis revealed that the inhibitory effects for human-OAT2 were competitive. Cephaloridine significantly decreased the viability of cells stably expressing human-OAT2, human-OAT1, human-OAT3 and human-OAT4. The decreased viability of cells stably expressing human-OAT1, human-OAT3 and human-OAT4 but not human-OAT2 was reversed by probenecid. In conclusion, human-OAT2 interacts with cephalosporins, and thus, human-OAT2 may mediate the uptake of cephalosporins on the basolateral side of the proximal tubule. The interaction of human-OAT2 with cephalosporins was the weakest among the basolateral human-OATs tested. In addition, it is suggested that human-OATs mediate cephaloridine-induced nephrotoxicity.
