Neither beta-lactamase nor bacteriocin produced by normal pharyngeal flora are related to bacteriologic treatment failures in GABHS pharyngitis. Cefadroxil seems to be more effective than penicillin V in eradicating GABHS from patients classified as more likely to be streptococcal carriers. However, among patients we classified as more likely to have bona fide GABHS pharyngitis, the effectiveness of cefadroxil and penicillin V seems to be comparable.

Antigen detection tests (ADTs) were used by 64% of the pediatricians; 85% used throat cultures. Strategies for diagnosing streptococcal pharyngitis were throat culture alone (38%), consider positive ADTs definitive and use throat culture when ADTs are negative (42%), ADT alone (13%), ADT and throat culture for all patients with pharyngitis (5%), and no tests for GABHS performed (2%). Thirty-one percent usually or always treated with antibiotics before test results were available. Only 29% of these "early treaters" always discontinued antibiotics when tests did not confirm the presence of group A streptococci. The drug of choice for treatment was penicillin (73%); another 26% preferred a derivative of penicillin, particularly amoxicillin. Many pediatricians altered their management when a patient had recurrent streptococcal pharyngitis. Nearly half of the respondents would use a different antibiotic than they used for routine acute streptococcal pharyngitis. They most often changed to erythromycin (25%), cefadroxil (23%), or amoxicillin-clavulanate (20%). Follow-up throat culture was obtained by 51% of pediatricians after treatment of recurrent streptococcal pharyngitis. A patient with chronic carriage of GABHS and symptoms of pharyngitis would be treated with an antibiotic by 84%; most (62%) would use a penicillin. Other choices were cephalosporins (19%), erythromycin (12%), clindamycin (3%), or rifampin plus penicillin (3%). Tonsillectomy was recommended for symptomatic carriers by 31% of respondents. Carriers without symptoms were less likely to be treated with antibiotics (23%) or referred for tonsillectomy (21%).

Acidity constants of six cephalosporin antibiotics, cefalexin, cefaclor, cefadroxil, cefotaxim, cefoperazon and cefoxitin are determined using capillary zone electrophoresis (CZE) and pH-potentiometric titrations. Since CZE is a separation method, it is not necessary for the samples to be of high purity and known concentration because only mobilities are measured. The effect on determination of dissociation constants of different matrices (serum, 0.9% NaCl, fermentation matrix) was examined. The advantages of CZE can be utilized in those fields where potentiometry has limitations (sample quantity, solubility, purity, simultaneous determinations), although pK(a) values that are close to each other can be determined by potentiometry with more accuracy.

The stable water-in-oil-in-water (W/O/W) multiple emulsion was prepared by a two-step procedure for emulsification using glyceryl tricaprylate (Panasate-800) as the oil phase. The water-soluble drugs such as cefadroxil, cephradine, 4-aminoantipyrine, and antipyrine were selected and entrapped separately in the inner aqueous phase of W/O/W multiple emulsion. In consideration of parenteral administration, pH 7.4 phosphate buffered saline was used in both inner and outer aqueous phases. Moreover, these multiple emulsions could be significantly stable for a month at room temperature by the addition of hydrophilic polymer like gelatin and of amino acid like lysine to the inner aqueous phase.

The proton-coupled oligopeptide transporter PEPT2 (SLC15A2) plays an important role in the disposition of di/tripeptides and peptide-like drugs in kidney and brain. However, unlike PEPT1 (SLC15A1), there is little information about species differences in the transport of PEPT2-mediated substrates. The purpose of this study was to determine whether PEPT2 exhibited a species-dependent uptake of glycylsarcosine (GlySar) and cefadroxil using yeast Pichia pastoris cells expressing cDNA from human, mouse, and rat. In such a system, the functional activity of PEPT2 was evaluated with [(3)H]GlySar as a function of time, pH, substrate concentration, and specificity, and with [(3)H]cefadroxil as a function of concentration. We observed that the uptake of GlySar was pH-dependent with an optimal uptake at pH 6.5 for all three species. Moreover, GlySar showed saturable uptake kinetics, with Km values in human (150.6 µM) > mouse (42.8 µM) ≈ rat (36.0 µM). The PEPT2-mediated uptake of GlySar in yeast transformants was specific, being inhibited by di/tripeptides and peptide-like drugs, but not by amino acids and nonsubstrate compounds. Cefadroxil also showed a saturable uptake profile in all three species, with Km values in human (150.8 μM) > mouse (15.6 μM) ≈ rat (11.9 μM). These findings demonstrated that the PEPT2-mediated uptake of GlySar and cefadroxil was specific, species dependent, and saturable. Furthermore, based on the Km values, mice appeared similar to rats but both were less than optimal as animal models in evaluating the renal reabsorption and pharmacokinetics of peptides and peptide-like drugs in humans.

Laboratory and clinical investigations were performed in the field of pediatrics with cefadroxil dry syrup, a new semi-synthetic cephalosporin antibiotic. (1) MIC of cefadroxil was measured, to compare with that of cephalexin (CEX), on 30 strains of S. aureus, 30 strains of S. pyogenes and 26 strains of E. coli, all of which were isolated clinically in the field of pediatrics. Two strains of S. aureus showed more than 100 microgram/ml with inoculum size of 10(8) cells/ml, and remaining 28 strains were distributed between 1.56 similar to or approximately 12.5 microgram/ml, while at inoculum size of 10(6) cells/ml, each 1 strain showed 25 microgram/ml and 50 microgram/ml, and the remaining strains were distributed between 1.56 similar to or approximately 3.13 microgram/ml. All 30 strains of S. pyogenes were inhibited the growth by less than 0.2 microgram/ml with inoculum size of both 10(8) cells/ml and 10(6) cells/ml. Three strains of E. coli showed MIC of more than 100 microgram/ml with inoculum size of 10(8) cells/ml, and the remaining 23 strains were distributed between 12.5 similar to or approximately 25 microgram/ml, while with inoculum size of 10(6) cells/ml, 3 strains showed more than 100 microgram/ml, and the remaining strains were distributed between 6.25 similar to or approximately 12.5 microgram/ml. In comparison with the results of CEX, cefadroxil was nearly equal to S. aureus and E. coli, whereas it was 2 grades superior to S. pyogenes. (2) A dose of 10 mg/kg of cefadroxil dry syrup was administered before 30 minutes of breakfast in 3 cases of children, and serum level, urinary level and recovery rate in urine were investigated. Average serum level was 15.2 +/- 2.39 microgram/ml in 1/2 hour, 16.4 +/- 2.3 microgram/ml in 1 hours. 10.1 +/- 2.8 microgram/ml in 2 hours, 3.8 +/- 1.5 microgram/ml in 4 hours and 1.0 +/- 0.4 microgram/ml in 6 hours, and average T 1/2 was 1.24 +/- 0.22 hours. Average urinary level was 857 +/0 232 microgram/ml in 0 similar to or approximately 2 hours, 690 +/- 180 microgram/ml in 2 similar to or approximately 4 hours and 249 +/- 55 microgram/ml in 4 similar to or approximately 6 hours, and average recovery ratio in urine was 86.3 +/- 17.5% within 0 similar to or approximately 6 hours. (3) Cefadroxil dry syrup was administered clinically in 20 cases of acute purulent tonsillitis, 5 cases of acute bronchitis, 14 cases of acute pharyngitis, 5 cases of acute purulent cervical lymphadenitis and 2 cases of acute urinary tract infection. Clinical efficacy, bacteriological effect and its side effect were investigated in total 46 cases of bacterial infection. A dose of 21.1 similar to or approximately 57.1 mg/kg of cefadroxil was administered daily, divided into 3, after each meal for 1 similar to or approximately 10 days, total dose being 0.5 similar to or approximately 11.0 g. Efficacy rate of cefadroxil, including excellent and effective effects, was 90.0% in acute purulent tonsillitis, 60.0% in acute bronchitis, 100.0% in acute pharyngitis, 80...

The binding of some cephalosporins of pharmacological interest, to human serum albumin was studied using ultrafiltration method. The identification of the binding sites in albumin was also performed using probes for the so-called sites I, II, bilirubin and fatty acids binding sites. Cephalosporins were classified into three groups according to their affinity for albumin: low affinity (K = 10-10(2) M-1), medium affinity (K = 10(3) M-1) and high affinity (K = 10(4) M-1). Cephalosporin binding to albumin produced a perturbation of several basic amino acids of the protein such as histidine and lysine. It was found that only cefuroxime, ceftazidime and cefoperazone interact slightly with site I on serum albumin, while site II possesses capacity to bind: cephradine, cephalexin, ceftazidime, ceftriaxone, cefoperazone, cefaclor and cefsulodin. The bilirubin binding site showed capacity to interact with a great number of cephalosporins: ceftriaxone, cefazolin, cephaloglycin, cefamandole, cefotaxime, cefoxitin, cefuroxime, cefoperazone and cefadroxil. Ceftriaxone showed capacity to bind to the fatty acid binding site on HSA. No relation was found between the displacement of the marker and the chemical nature of the substituents at R1 and R2. Cephalosporins interact with HSA at the binding region that involves: tyrosyl 411, histidyl 146 and lysyls 195, 199, 225, 240 and 525 residues. The chemical modification of specific amino acids showed that the interaction of these amino acids with beta lactam antibiotics is not carried out to the same extent for all the cephalosporins tested. The results obtained revealed that the binding sites for cephalosporins on albumin are structurally heterogeneous, having different amino acids in the vicinity of the ligand molecule.

The new oral cephalosporins cefpodoxime, cefixime, cefdinir, cefetamet and ceftibuten demonstrate enhanced activity against Enterobacteriaceae susceptible to the established compounds as well (e.g. cefuroxime, cefaclor, cefadroxil). In addition, cefpodoxime, cefixime, cefdinir, cefetamet and ceftibuten include in their spectrum species hitherto resistant to oral cephalosporins (Proteus vulgaris, Providencia spp., Yersinia enterocolitica). Besides, the majority of these compounds demonstrate relevant activity (MIC50 equal to or below 2 mg/l) against Enterobacter spp., Citrobacter freundii, Serratia spp. and Morganella morganii. Ceftibuten is the most potent oral cephalosporin against most of the Enterobacteriaceae. Non-fermentative bacilli (Acinetobacter spp., Pseudomonas spp.) remain completely resistant to oral cephalosporins (except some Acinetobacter species against cefdinir and Pseudomonas cepacia against ceftibuten). Antistaphylococcal activity for oral cephalosporins is highest for cefdinir followed by BAY 3522, cefprozil, cefuroxime and cefpodoxime. Loracarbef, cefaclor and cefadroxil are about equally active, while the other compounds are only weakly active (cefixime) or inactive (cefetamet, ceftibuten). Enterococci are insensitive to new generation oral cephalosporins as they have been to established compounds. The most active oral cephalosporins against hemolytic streptococci are cefdinir and cefprozil. Streptococcus pneumoniae, Streptococcus milleri and Streptococcus mitior are most susceptible to cefpodoxime, cefdinir, cefuroxime and BAY 3522. Penicillin resistant pneumococci have to be regarded as resistant to all oral cephalosporins. Fastidious pathogens like Haemophilus spp., Moraxella catarrhalis and Neisseria gonorrhoeae are more susceptible to cefpodoxime, cefixime, cefdinir, cefetamet and ceftibuten than to the other oral cephalosporins. The activity of oral cephalosporins is only weak against Listeria spp., Helicobacter pylori and anaerobic pathogens (except BAY 3522). Bordetella pertussis remains resistant to all absorbable cephalosporins. Progress in antibacterial activity of oral cephalosporins was mainly achieved by cefpodoxime, cefixime, cefdinir, cefetamet and ceftibuten against Enterobacteriaceae and the fastidious pathogens and against staphylococci and the nonenterococcal streptococci by cefdinir, BAY 3522, cefprozil and cefpodoxime.

The mechanism of intestinal transport of valacyclovir (VACV), the L-valyl ester prodrug of acyclovir, was investigated in rats using an in situ intestinal perfusion technique. VACV demonstrates an oral bioavailability that is three to five time greater than acyclovir, concentration dependent, and saturable in humans. Homogenate and perfused buffer stability results demonstrated that VACV was increasingly unstable with increasing pH. VACV was converted to ACV in a concentration dependent manner during a single pass through the intestinal segment. Perfusions were performed at 37 degrees C, pH 6.5, and under iso-osmotic conditions (290 +/- 10 mOsm L-1). Intestinal outlet concentrations were corrected for VACV that was converted to ACV during the perfusion. The effective dimensionless intestinal permeability (P*e) of VACV was concentration dependent, saturable (intrinsic Km = 1.2 +/- 0.7 mM), and significantly reduced (p < 0.05) in the presence of peptide analogues (amoxicillin, ampicillin, cefadroxil, and cephradine), by the organic anion, p-amino hippuric acid and by the organic cation quinine. VACV transport was not inhibited by classical nucleoside competitive substrates or inhibitors or by valine. These results suggest that H(+)-oligopeptide, H(+)-organic cation, and organic anion transporters are involved in the small intestinal uptake of VACV. The permeability of VACV in the colon was very low, indicating that VACV is predominantly absorbed from the small intestine. VACV P*e was not altered in the presence of glucose-induced convective fluid flow, suggesting that carrier-mediated, transcellular uptake is the predominant absorption pathway of VACV in rat small intestine. Based on these results, the oral bioavailability of VACV appears to be significantly influenced by the preabsorptive conversion of VACV to the poorly absorbed ACV, by the involvement of multiple transporters in VACV small-intestinal uptake, and by the low permeability of VACV in the colon.

Amorphous lactose and cefadroxil undergo recrystallization when the moisture level in the surroundings exceeds the threshold values specific to each compound. During the sorption phase, heat is evolved fairly linearly as a function of consumed moisture, and also after the recrystallization, the heats indicate linear behavior. The heat values for the desorption phase of amorphous lactose and the adsorption of crystalline lactose coincide. With the different anhydrous forms of theophylline, the hydration takes place more rapidly in the metastable form 1, and generally, the process is more energetic in form 1. In all cases, the gravimetric results agree with the water sorption uptakes calculated from the calorimetric data.

Gram-negative neonatal septicemia was diagnosed in a premature Standardbred colt. Clinical signs included lethargy, weakness, loss of suckle reflex, tachypnea, and injected mucous membranes. Sequelae included pneumonia, omphalophlebitis, septic arthritis, and osteomyelitis. Prepartum maternal uterine infection, premature delivery, abnormal parturition with premature fetal membrane separation, and failure of passive transfer of colostral immunoglobulins increased the foal's risk for developing sepsis. Treatment included administration of moxalactam disodium and cefadroxil. The clinical efficacy of cephalosporin antibiotics in the treatment of gram-negative sepsis is discussed.

Data are presented on the effect of ethanol on the intestinal absorption and excretion in rats of two beta-lactam antibiotics, cephalexin (CFX) and cefadroxil (CFD). A recirculating perfusion technique within an antibiotic concentration range of 0.5 to 50 mM was used. Ethanol was administered either in an acute form into the intestine or in a chronic form as a 15% drinking solution for 2 months. The results are normalized in relation to the metabolic body weight, intestinal length, and osmotic conditions. Acute ethanol treatment decreases the antibiotic absorption; biliary excretion of CFD is increased, while urinary excretion of CFX is lowered. Chronic treatment shows slight negative effects on the absorption of CFX and CFD. Results are interpreted on the basis of the effect of ethanol on biological membranes. Enhanced urinary excretion after acute ethanol treatment, as well as differences between transport mechanisms, are invoked to explain these effects.

The in-vitro activity of a new oral carbacephem, LY163892, was compared with cefaclor, cephalexin, cephradine, cefadroxil and selected penicillins against 529 bacterial isolates. LY163892 exhibited greater activity in vitro than all four cephalosporins against Haemophilus influenzae, beta-lactamase producing Altace Generic Form Branhamella catarrhalis, Escherichia coli, Klebsiella spp. and Proteus mirabilis. LY163892 had equivalent potency to cefaclor against non-beta-lactamase producing B. catarrhalis, streptococci and Staphylococcus aureus. Group D beta-haemolytic streptococci, Proteus vulgaris, and methicillin-resistant staphylococci were universally resistant to LY163892 and the four cephalosporins. Broth dilution experiments indicated that LY163892 was bactericidal against a range of Gram-positive and Gram-negative organisms and suggested that the antibiotic had a similar degree of stability to the beta-lactamases of H. influenzae, B. catarrhalis and Staph. aureus as did cefaclor. The susceptibility of 16 strains of H. influenzae to LY163892 and cefaclor were equivalent when estimated using three different commercially available agar media. Addition of carbon dioxide to the incubation atmosphere significantly reduced the potency of both drugs.

Cefprozil is a new oral second generation cephalosporin. Its in vitro antimicrobial activity was evaluated against 371 recent clinical isolates from patients with respiratory infections. We tested the susceptibility of 244 streptococci (96 Streptococcus pneumoniae, 105 group viridans streptococci, 32 Streptococcus agalactiae, and 11 group A beta-hemolitic streptococci) 107 Haemophilus influenzae, and 20 oxacillin-susceptible S.aureus (OSSA). The isolates were susceptibility tested against cefprozil, cefaclor and amoxicillin/clavulanic acid by the E-test method; and against cefadroxil, cefuroxime, cefetamet, erythromycin, and azythromycin by disk diffusion. The methods and the susceptibility categorization followed the National Committee for Clinical Laboratory Standards (NCCLS) procedures. Amoxicillin/clavulanic acid was slightly more active againstH.influenzae (MICs(90) 0.5µg/mL) than cefprozil or cefaclor (MICs(90) 4 and 2µg/mL respectively). Cefprozil demonstrated potent activity against streptococci. Against S.pneumoniae, cefprozil was 2-4 fold more active than cefaclor (MICs(90)0.125 and 0.38µg/mL, respectively). S. pneumoniae susceptibility was 84% to penicillin, 95% to erythromycin and 97% to azithromycin by disk diffusion. Viridans streptococci showed higher MICs for cefprozil and cefaclor (MICs(90) 4µg/mL and 8µg/mL, respectively) and only 50% susceptibility to the macrolides. Cefprozil was four times more active than cefaclor and as active as Buy Amoxil amoxieillin/clavulanic acid against group A beta-hemolytic streptococci and S.agalactiae. These three compounds showed similar activity against OSSA. In conclusion, cefprozil demonstrated excellent in vitro activity against bacterial species responsible for respiratory infections in São Paulo.

In the present study, an intestinal pH, disintegrating and non-disintegrating dual capsular system using formaldehyde vapor and phase transition technique, respectively, was developed to achieve delayed as well as improved osmotic flow for the model drug cefadroxil. Formaldehyde vapor was used to attain gastric resistance to the outer gelatin capsule, which disintegrated at the intestinal pH to give a non-disintegrating asymmetric membrane capsule (AMC). The AMC was prepared via dry phase inversion process. The effects of different formulation variables were studied based on 2³ factorial design, namely, level of osmogen, ethylcellulose, and pore former, apart from studying the effects of varying osmotic pressure, agitation intensity, and intentional defect on drug release. Scanning electron microscopy showed an outer dense non-porous and an inner lighter porous region for the prepared asymmetric membrane. Statistical test was applied for in-vitro drug release at P > 0.05. The Amoxil Order best formulation in the design closely corresponded to the extra design checkpoint formulation by a similarity (f₂) value of 95.28. The drug release was independent of the agitation intensity and intentional defect of the film but dependent on the osmotic pressure of the dissolution medium. The release kinetics followed zero-order, and mechanism of release was Fickian diffusion.

The most common causative pathogens in lower respiratory disease are S. pneumoniae, H. influenzae and S. pyogenes. Cefadroxil and co-trimoxazole, both orally administered broad spectrum antibiotics, are effective against these organisms when given in a twice-daily regimen. In this open randomised study, 42 patients with lower respiratory tract infections received cefadroxil 1 g or co-trimoxazole 1 double-strength tablet every 12 hours for a mean duration of 11 and 13 days, respectively. Pathogens were isolated in the pre-treatment sputum of 51% of patients Rosuvastatin Generic Vs Crestor given cefadroxil and in 25% of those who received co-trimoxazole. Similar overall cure rates were observed after treatment with cefadroxil (67%) and co-trimoxazole (60%); sputum purulence was similarly diminished by both drugs (91% and 85%, respectively). Neither antibiotic caused serious side effects. Thus, in a convenient twice-daily regimen, cefadroxil and co-trimoxazole are comparably effective in treating lower respiratory tract infections.

Of 101 pathogenic E. coli isolates, more than 55% were resistant to at least one or more of the tested compounds, and 36.6% of the isolates showed multiple-drug-resistant phenotypes. The most common resistances observed were against tetracycline (45.5%), trimethoprim-sulphamethoxazole (26.7%), nalidixic acid (25.7%), ampicillin (25.7%), and streptomycin (20.8%). Resistance to ciprofloxacin (12.9%), chlormaphenicol (8.9%), nitrofurantoin (2%), and gentamicin (2%) was also observed, and none of the isolates were resistant to tigecycline as well as extended spectrum beta-lactamase (ESBL) producers. One isolate was resistant to cefuroxime (1%), cefadroxil (1%), and mecillinam (1%) but was not an ESBL producer. Resistance rates, although significant in Bangladeshi isolates, were found to be lower than those reported for avian isolates from the Republic of Korea and clinical, avian, and environmental isolates from Bangladesh. The high level of antibiotic resistance in avian pathogens from Bangladesh is worrisome and indicates that widespread use of antibiotics as feed additives for growth promotion and disease prevention could have negative implications for human and animal health and the environment.

Cefadroxil has been used for the treatment of acute osteomyelitis. However, its pharmacokinetics and pharmacodynamics have not been studied Zocor Going Generic in these patients. We evaluated the kinetics and dynamics of cefadroxil in a pediatric patient with osteomyelitis caused by Staphylococcus aureus. After initial clinical improvement on intravenous nafcillin, the patient received oral cefadroxil, 60 mg/kg every 12 h. Blood samples were collected at 0, 1, 2, 4, 6, 8 and 12 h; bactericidal titers were determined at 2 and 12 h. Cefadroxil was measured by an HPLC method. The peak and trough serum concentration of cefadroxil was 35.4 and 0.5 micrograms/ml, respectively. The oral clearance and elimination half-life were 11.5 ml/min/kg and 2.4 h, respectively. The peak bactericidal titer was 1:4 and the trough titer was less than 1:2 for the infecting organism. The child's finger appeared worse with an increase in swelling and erythema after 2 days of cefadroxil therapy. Cefadroxil was discontinued and the patient was treated successfully with intravenous nafcillin. The apparent failure of cefadroxil therapy can be explained by lower than recommended peak (greater than or equal to 1:8) and trough (greater than or equal to 1:2) titers for therapeutic success. Thus, an alternative dosage regimen of cefadroxil should be considered in the future studies.

Baicalin, a main constituent of the rhizome of Scutellaria baicalensis, is metabolized to baicalein and oroxylin A in the intestine before its absorption. To understand the role of intestinal microflora in the pharmacological activities of baicalin, we investigated its anti-inflammatory effect in mice treated with and without antibiotics. Orally administered baicalin showed the anti-inflammatory effect in mice than intraperitoneally treated one, apart from intraperitoneally administered its metabolites, baicalein and oroxylin A, which potently inhibited LPS-induced inflammation. Of these metabolites, oroxylin A showed more potent anti-inflammatory effect. However, treatment with the Benicar Generic Equivalent mixture of cefadroxil, oxytetracycline and erythromycin (COE) significantly attenuated the anti-inflammatory effect of orally administered baicalin in mice. Treatment with COE also reduced intestinal bacterial fecal β-glucuronidase activity. The metabolic activity of human stools is significantly different between individuals, but neither between ages nor between male and female. Baicalin was metabolized to baicalein and oroxylin A, with metabolic activities of 1.427 ± 0.818 and 1.025 ± 0.603 pmol/min/mg wet weight, respectively. Baicalin and its metabolites also inhibited the expression of pro-inflammatory cytokines, TNF-α and IL-1β, and the activation of NF-κB in LPS-stimulated peritoneal macrophages. Of them, oroxylin A showed the most potent inhibition. Based on these findings, baicalin may be metabolized to baicalein and oroxylin A by intestinal microflora, which enhance its anti-inflammatory effect by inhibiting NF-κB activation.

Most cephalosporins can only be administered parenterally. Among agents that are absorbed from the gastrointestinal tract, those with bioavailabilities of 85 to 90% include cefroxadine, cefadroxil, cefsumide, cephalexin, cephradine, cephacetrile, and cefazaflur. Most cephalosporins are eliminated rapidly, with serum half-lives (t1/2s) of 1 to 2 hours. Exceptions are cefonicid with a t1/2 of 4.4 hours, cefpiramide with a t1/2 of 5.0 hours, and cefotetan with a t1/2 of 3.5 hours. The longest half-life is shown by ceftriaxone with a t1/2 of 8.5 hours. Cephalosporins are eliminated mostly by the kidneys, some with a substantial contribution from active tubular secretion, which is blocked by probenecid. The degree of metabolism varies. Only a few cephalosporins have a high biliary elimination. For example, with intravenously administered cefoperazone, about 70% appears in bile. High biliary elimination is also observed with cefmenoxime, ceftriaxone, cefbuperazone, and latamoxef (moxalactam). Because these are not appreciably absorbed from the gastrointestinal tract, the consequence is high intraintestinal concentrations of the drugs and a marked ensuing depression of the normal microflora with simultaneous emergence of resistant bacteria. The untoward ecological impact may even lead to Clostridium difficile-associated enterocolitis.

An in vitro comparison of the activities of 13 oral antimicrobial agents against clinical isolates of bacteria commonly responsible for causing upper respiratory tract infections was performed. With regard to Haemophilus influenzae, beta-lactamase-negative strains were susceptible to amoxycillin, augmentin, cefaclor, erythromycin, trimethoprim, cotrimoxazole and tetracycline, with CL 284,635 being the most active agent. With the exception of amoxycillin these drugs were also active against beta-lactamase-producing strains. CL 284,635 was also very active against Branhamella catarrhalis isolates, including beta-lactamase-producing strains, but was less active against the Gram-positive bacteria tested. Cefadroxil, cephradine and cephalexin were mainly active against Gram-positive pathogens. Based on minimum inhibitory concentration determinations, cefaclor, augmentin and co-trimoxazole would be appropriate drugs for the treatment of those cases of otitis media and sinusitis where H. influenzae and Streptococcus pneumoniae are important pathogens provided they are susceptible to these agents.

A ten-day, randomized, open-label study was conducted to compare the efficacy of 1,000 mg of cefadroxil once daily and 250 mg of cefaclor TID in 200 black patients with skin and soft-tissue infections caused by microorganisms sensitive to these cephalosporins. Statistically, the clinical results with each drug were not significantly different: 91% efficacy with cefadroxil and 95% efficacy with cefaclor. The important difference between cefadroxil and cefaclor is the remarkably longer half-life of cefadroxil, which makes once-a-day dosing possible and offers greater patient convenience and the likelihood of better compliance. In an analysis of compliance, only 2% of the patients in the cefadroxil group (20 capsules given to each patient) returned unused capsules; 77% in the cefaclor group (30 capsules given to each patient) returned unused capsules.
