cefuroxime-axetil and Bronchitis

Studies evaluating short-course therapy have focused on prevalent infections with demonstrable aetiology. Metaanalyses of clinical trials demonstrate that uncomplicated acute otitis media in children can be successfully treated with a 5-day course of cefuroxime axetil. In the treatment of tonsillopharyngitis, 4 - 5-day courses of oral cephalosporins compared favourably with the standard 10-day penicillin V regimen. The clinical cure rate and the bacteriological eradication rate were both significantly higher for cephalosporins than for penicillin V. Bacteriological failure rates for cephalosporins were about half those for penicillin. In studies on acute bacterial exacerbations of chronic bronchitis, no difference in the clinical cure rates or relapse rates was found between short-course therapy using cephalosporins and standard courses. The short courses had the advantage of improved gastrointestinal tolerance compared with longer durations of treatment. The results suggest that new short-course dosing regimens are viable and may be favourable in terms of increased tolerability, reduction in healthcare costs, enhanced patient compliance and the control of the development of antibiotic resistance.

Cefprozil was evaluated in four multicentre comparative studies in the treatment of acute respiratory tract infections. In two studies, cefprozil 500 mg q. 12 hours was compared to cefaclor 500 mg q. eight hours for ten days of therapy. Randomization was on a 2:1 (cefprozil:cefaclor) basis in the European centres and 1:1 in North America. The clinical efficacy in acute bronchitis was 88% (284 out of 324 patients) for cefprozil and 88% (183 out of 208) for cefaclor, with successful bacteriological eradication of the causative pathogen in 86% and 82% of the patients, respectively. Amongst the patients with acute exacerbations of chronic bronchitis, the clinical response rate of 80% (59 out of 74) for cefprozil appeared superior to that of cefaclor at 62% (p = 0.067), whilst the bacteriological response rates were 62% (36 out of 58) for cefprozil and 74% (20 out of 27) for cefaclor. In pneumonia, the clinical response rates for cefprozil and cefaclor therapy were similar, 82% vs. 79%, although bacteriological eradication rates were better for cefprozil at 82% than for cefaclor at 71%. In the comparison of cefprozil with cefuroxime axetil, a total of 170 patients were evaluable. The clinical and bacteriological response rates for cefprozil of 95% and 100% were better than those for cefuroxime axetil 500 mg q. 12 hours of 84% and 75%, respectively. In the cefprozil vs. amoxicillin-clavulanate, 500 mg q. eight hours comparative study, the two antibiotics displayed no significant difference in clinical or bacteriological responses.(ABSTRACT TRUNCATED AT 250 WORDS)

A randomized, double-blind, double-dummy, three-arm parallel design, multicentre study was conducted among adult patients with acute exacerbation of chronic bronchitis (AECB) in order to compare the efficacy and safety of two different doses of levofloxacin with cefuroxime axetil. A total of 832 patients were randomized to receive oral levofloxacin (250 mg od or 500 mg od) or oral cefuroxime axetil (250 mg bd) for 7-10 days. The primary efficacy analysis was based on the clinical response in patients with bacteriologically confirmed AECB, determined 5-14 days after the end of therapy (per-protocol population). Of 839 patients enrolled (at 71 centres in 14 countries), seven were not treated, giving an intention-to-treat (ITT) population of 832. In total, 281 patients received levofloxacin 250 mg, 280 received levofloxacin 500 mg and 271 received cefuroxime axetil. The cure rates in the ITT population were: levofloxacin 250 mg, 70% (196/281); levofloxacin 500 mg, 70% (195/280); cefuroxime axetil, 61% (166/271); those in the per-protocol population were: 78% (121/156), 79% (108/137) and 66% (88/134), respectively. Both doses of levofloxacin were at least as effective as cefuroxime axetil and were active against the main pathogens of clinical relevance (Haemophilus influenzae, Streptococcus pneumoniae and Moraxella catarrhalis). All three treatment regimens were equally well tolerated. In conclusion, the results show that levofloxacin (250 mg and 500 mg) od is effective and well tolerated in the treatment of AECB in adult patients.

The objective of this randomized, double-blind study was to compare the clinical efficacy of levofloxacin at two different dosages with that of cefuroxime axetil in patients with acute purulent exacerbations of chronic bronchitis and, in particular, to assess the impact of the susceptibility to levofloxacin on the clinical findings. In total, 124 evaluable patients were treated for 7 days with oral levofloxacin 250 mg or 500 mg od, or cefuroxime axetil 250 mg bd. Sputum cultures were monitored pre-treatment, and at 1 and 7 days after the end of treatment. The susceptibility of Streptococcus pneumoniae isolates was tested by agar dilution in Columbia blood agar and by disc diffusion, but all other isolates were tested solely by the disc diffusion method. A greater number of infections were eradicated by levofloxacin than by cefuroxime axetil: infections were eradicated in 68% of patients receiving the 500 mg dosage and in 63% of those taking 250 mg levofloxacin, whereas the eradication rate with the comparator drug was much lower (48%). Against all pre-treatment S. pneumoniae isolates (n = 39), the MICs of levofloxacin were between 0.25 and 2 mg/L (geometric mean 0.95 mg/L), similar to those of the post-treatment strains (n = 32; mean 1.11 mg/L). All except one of the S. pneumoniae isolates were susceptible to penicillin G (MIC < or = 0.06 mg/L), and the remaining isolate was inhibited by 0.5 mg/L of penicillin G, but was fully susceptible to levofloxacin. Some pretreatment strains of Pseudomonas aeruginosa were resistant to levofloxacin, but many more resistant strains were encountered afterwards. All strains of Moraxella catarrhalis and Haemophilus influenzae were highly susceptible to levofloxacin in the disc diffusion tests. All the antimicrobial agents used in the study were well tolerated: only two patients discontinued treatment because of adverse drug effects. The results of this study indicated that, although there were some failures in patients with S. pneumoniae and P. aeruginosa infections, resistance to levofloxacin did not emerge rapidly among strains of S. pneumoniae during therapy with levofloxacin, and that natural resistance among pneumococci, H. influenzae and M. catarrhalis was rare.

The bacteriological eradication rates of Streptococcus pneumoniae from sputum of patients experiencing acute exacerbations of chronic bronchitis (WHO definition) have been compared following therapy with either cefuroxime axetil 250 mg b.d. or cefixime 200 mg b.d. All patients were hospitalised for an acute exacerbation of chronic bronchitis. The study design was a multicentre, double-blind, randomised, parallel group with patients giving written informed consent initially. Patients were recruited to the study if they met the WHO definition of chronic bronchitis, were aged 30-75 years and had a high probability of S. pneumoniae infection based on initial sputum Gram stain. All S. pneumoniae isolates were serotyped and susceptibility tested at the National Reference Centre, Paris. S. pneumoniae was eradicated more rapidly following cefuroxime axetil administration than after cefixime and this difference was statistically significant (p = 0.002) at 2-4 days post-treatment. Clinical endpoints showed a similar trend--94% response to cefuroxime axetil compared with 71% response to cefixime (RR 6.39:1). Cefuroxime eradicated S. pneumoniae significantly more rapidly than cefixime and patients in the cefuroxime axetil arm had favourable clinical criteria. The data suggest that focused antibacterial studies may be helpful in evaluating antibiotics in acute exacerbation of chronic bronchitis.

In a prospective, multicenter, double-blind study, the interval to clinical relapse in patients with acute bacterial exacerbations of chronic bronchitis from whom a pretherapy pathogen was isolated was compared following treatment with ciprofloxacin or cefuroxime axetil. Clinical and microbiological responses at the end of therapy were secondary efficacy variables. Outpatients randomly received either ciprofloxacin or cefuroxime axetil (500 mg twice a day for 14 days). Three hundred seven patients with acute exacerbations of chronic bronchitis were enrolled, of whom 208 had an exacerbation due to a bacterial pathogen. Clinical resolution at the end of ciprofloxacin and cefuroxime axetil therapy for patients for whom efficacy could be evaluated was 93% and 90%, respectively. Bacteriologic eradication rates were statistically higher for ciprofloxacin recipients (96% [89 of 93]) than for cefuroxime axetil recipients (82% [80 of 97]) (P < .01). The median infection-free interval was 146 days for ciprofloxacin recipients vs. 178 days for cefuroxime axetil recipients (P = .37). In conclusion, ciprofloxacin was associated with an infection-free interval and clinical response that were similar to those associated with cefuroxime axetil, but the bacteriologic eradication rate associated with ciprofloxacin was statistically significantly higher than that associated with cefuroxime axetil.

A prospective, multicentre, randomized, open-label, parallel group study compared the efficacy, safety and tolerability of cefuroxime 750 mg iv administered either twice daily (bd) or three times daily (tds) for 48-72 h, followed by oral cefuroxime axetil 500 mg bd for 5-7 days in a sequential therapy regimen for the treatment of acute exacerbations of chronic bronchitis. A total of 628 adult patients entered the study; 323 in the cefuroxime tds group and 305 in the cefuroxime bd group. For clinically evaluable patients, the post-treatment clinical response rate was 86% and 88% in the cefuroxime tds and bd groups, respectively. Cure was maintained at follow-up (14-28 days after treatment completion) in 85% of the cefuroxime tds group and 84% of patients in the cefuroxime bd group. A total of 189 pathogens was isolated, the most common being Haemophilus influenzae (17%), other Haemophilus spp. (15%), Streptococcus pneumoniae (15%) and Enterobacteriaceae (23%). At the post-treatment assessment, 66% and 70% of pathogens were cleared in the cefuroxime tds and bd groups, respectively. Both treatment regimens were well tolerated. The incidence of drug-related adverse events was 7% in the cefuroxime tds group and 6% in the cefuroxime bd group; the most common side-effects were gastrointestinal. Qualitative and quantitative markers were used to determine the optimal time to switch from iv to oral therapy and, of these, peak expiratory flow rate was shown to be the most useful in the present study. In conclusion, the findings of this study support the use of a bd dosing schedule of cefuroxime in a sequential therapy regimen with oral cefuroxime axetil, demonstrating it to be clinically equivalent to the standard tds dosage currently used, as well as being simpler and more convenient to administer at a lower cost.

The cephalosporin antibiotic zinnat was given to 171 outpatients with bronchopulmonary infections. Pneumonia patients received 500 mg, patients with acute bronchitis or exacerbation of chronic bronchitis 250 mg twice a day. The recovery was registered in 97.7, 98.8 and 91.8% of patients, respectively. The drug proved effective, low-toxic, convenient in use. Wide-spectrum action, significant activity against both gram-positive and gram-negative pathogens make zinnat a promising drug for outpatient treatment of bronchopulmonary infections.

Five hundred thirty-seven patients were enrolled in two independent, investigator-blinded, multicenter, randomized clinical trials comparing the clinical and bacteriologic efficacies and the safety of 5- or 10-day treatment with cefuroxime axetil with those of 10-day treatment with amoxicillin-clavulanate in the treatment of secondary bacterial infections of acute bronchitis. Patients received either 5 or 10 days of treatment (n = 177 in each group) with cefuroxime axetil at 250 mg twice daily or 10 days of treatment (n = 183) with amoxicillin-clavulanate at 500 mg three times daily. Patients in the cefuroxime axetil (5 days) group received placebo on days 6 to 10. Bacteriologic assessments were based on sputum specimen cultures obtained preceding and, when possible, following treatment. Organisms were isolated from the pretreatment sputum specimens of 242 of 537 (45%) patients, with the primary pathogens being Haemophilus influenzae, Haemophilus parainfluenzae, Moraxella catarrhalis, Streptococcus pneumoniae, and Staphylococcus aureus (28, 25, 13, 9, and 8% of isolates, respectively). Pathogens were eradicated or presumed to be eradicated in 87% (52 of 60), 91% (53 of 58), and 86% (60 of 70) of bacteriologically evaluable patients treated with cefuroxime axetil (5 days), cefuroxime axetil (10 days), and amoxicillin-clavulanate, respectively. A satisfactory clinical outcome (cure or improvement) was achieved in 82% (107 of 130), 86% (117 of 136), and 83% (130 of 157) of the clinically evaluable patients treated with cefuroxime axetil (5 days), cefuroxime axetil (10 days), and amoxicillin-clavulanate, respectively. Treatment with amoxicillin-clavulanate was associated with a significantly higher incidence of drug-related adverse events than was treatment with cefuroxime axetil for either 5 or 10 days (P = 0.001), primarily reflecting a higher incidence of drug-related gastrointestinal adverse events (37 versus 19 and 15%, respectively; P < 0.001), particularly diarrhea and nausea. These results indicate that treatment with cefuroxime axetil at 250 mg twice daily for 5 days is as effective as treatment for 10 days with either the same dose of cefuroxime axetil or amoxicillin-clavulanate at 500 mg three times daily in patients with acute bronchitis. In addition, treatment with cefuroxime axetil for either 5 or 10 days is associated with significantly fewer gastrointestinal adverse events, particularly diarrhea and nausea, than is 10-day treatment with amoxic

Betalactams, mainly when orally administered, may lead to intestinal flora modifications related to their spectrum of activity, rate of absorption and degradation. therefore it is important to investigate the possible influence of recently developed oral cephem derivatives on normal human microflora. We have investigated the impact on normal human intestinal flora in a 10-day course with cefetamet-pivoxil (CET, 500 mg BID) in comparison to cefixime (CFX, 400 mg qD) or cefuroxime axetil (CA, 250 mg BID) in 24 patients suffering from acute exacerbation of chronic bronchitis. Stool specimens were taken before (day 0), at the end (day 10) and 14 days after treatment (day 24) and quali-quantitative microflora composition was determined with a detection limit of 10 CFU/g dry weight. Treatment with CET caused slight and non-significant modifications of normal intestinal flora. On the contrary CFX and CA significantly affect Enterobacteriaceae and clostridia with a concomitant increase in enterococci for CFX. With both CFX and CA there was a new appearance of Salmonella spp. as well as Clostridium difficile in 4 and 2 cases, respectively. Therefore CET seems to affect normal bowel flora minimally in comparison to other oral cephalosporins. This aspect might contribute to the low incidence of GI related side effects in patients treated with CEt for longer than 1 week.

Cefprozil was evaluated in four multicentre comparative studies in the treatment of acute respiratory tract infections. In two studies, cefprozil 500 mg q. 12 hours was compared to cefaclor 500 mg q. eight hours for ten days of therapy. Randomization was on a 2:1 (cefprozil:cefaclor) basis in the European centres and 1:1 in North America. The clinical efficacy in acute bronchitis was 88% (284 out of 324 patients) for cefprozil and 88% (183 out of 208) for cefaclor, with successful bacteriological eradication of the causative pathogen in 86% and 82% of the patients, respectively. Amongst the patients with acute exacerbations of chronic bronchitis, the clinical response rate of 80% (59 out of 74) for cefprozil appeared superior to that of cefaclor at 62% (p = 0.067), whilst the bacteriological response rates were 62% (36 out of 58) for cefprozil and 74% (20 out of 27) for cefaclor. In pneumonia, the clinical response rates for cefprozil and cefaclor therapy were similar, 82% vs. 79%, although bacteriological eradication rates were better for cefprozil at 82% than for cefaclor at 71%. In the comparison of cefprozil with cefuroxime axetil, a total of 170 patients were evaluable. The clinical and bacteriological response rates for cefprozil of 95% and 100% were better than those for cefuroxime axetil 500 mg q. 12 hours of 84% and 75%, respectively. In the cefprozil vs. amoxicillin-clavulanate, 500 mg q. eight hours comparative study, the two antibiotics displayed no significant difference in clinical or bacteriological responses.(ABSTRACT TRUNCATED AT 250 WORDS)

In a large multinational study, the clinical and bacteriological efficacy of intravenous cefuroxime 750 mg t.i.d. followed by oral cefuroxime axetil 500 mg b.i.d. was compared to that of amoxicillin plus clavulanic acid (CA) administered as 1.2 g intravenously t.i.d. followed by 625 mg orally t.i.d. in the treatment of lower respiratory tract infections in hospitalised patients. A total of 512 patients were entered (256 in each treatment group). All were suffering from pneumonia or acute exacerbations of chronic bronchitis or bronchiectasis and required initial parenteral antibiotic therapy. Parenteral therapy lasted 48 to 72 h and was followed by five days of oral therapy. The clinical responses in the two treatment groups were very similar: 223 of 256 (87.1%) patients were cured or improved with cefuroxime/cefuroxime axetil compared to 220 of 256 (85.9%) with amoxicillin/CA. Positive pre-treatment sputum samples were obtained from 44% of the patients. Clearance rates obtained were again similar: 72.8% with cefuroxime/cefuroxime axetil and 70% with amoxicillin/CA. Ten percent of the isolates were beta-lactamase producers, similar numbers of which were cleared in both groups. Both regimens were generally well tolerated, with only 5% of patients treated with the cefuroxime regimen and 4.3% of patients treated with amoxicillin/CA experiencing drug-related adverse events. Cefuroxime/cefuroxime axetil "follow-on" therapy produces clinical and bacteriological efficacy equivalent to that of amoxicillin/CA, with the advantage of twice daily oral administration.

128 Patients (45 female, 83 male) with acute exacerbations of chronic bronchitis were treated with either cefuroxime axetil 2 x 500 mg/d (n = 65) or ofloxacin 2 x 200 mg/d for 7-8 days in a randomized controlled multicenter trial. From the respective groups, the results of 61 and 59 patients could be evaluated. Positive sputum tests were available in 85 cases (56 monoinfections, 29 mixed infections) prior to treatment. According to final clinical assessment, cure was achieved with cefuroxime axetil in 75%, but only in 50% with ofloxacin. The clinical efficacy of cefuroxime axetil was judged by the physicians to be more reliable than ofloxacin. The difference is statistically significant (p less than 0.05). Therapy with ofloxacin had to be terminated in 2 cases due to side effects. Altogether 4 adverse events were documented with ofloxacin. Compared with ofloxacin, cefuroxime axetil showed better efficacy and low risk of side effects.

The aim of this multicenter, prospective randomized trial was to compare the efficacy and safety of cefuroxime-axetil and amoxycillin/clavulanic acid for the treatment of infectious bronchitis in the elderly patient. Between January and April 1989, 157 out patients aged 60 years or more and presenting with infectious bronchitis were treated with either cefuroxime-axetil (250 mg bid), or the association amoxycillin/clavulanic acid (500 mg/125 mg bid). The two treatment groups were comparable at the time of inclusion; the mean age was 70 years, 82% of the patients were febrile, 75% presented purulent expectoration, 24% had a history of chronic bronchitis and 19% received symptomatic treatment was NSAIDs. The mean duration of treatment was 9 days. Clinical efficacy was assessed by the investigators. While fever and cough resolved similarly in the two groups, statistically fewer patients presented persistent purulent expectoration in the cefuroxime-axetil treatment group than in the group receiving amoxycillin/clavulanic acid (2% and 13%, respectively, p = 0.03). The proportion of patients who reported at least one side-effect was 3.6% in the cefuroxime-axetil treatment group against 21.6% of those who received the association (p = 0.006).

Cefuroxime axetil was compared with cefaclor for the therapy for lower respiratory tract infections. Sixty-one patients were randomized to receive the following drug dosages: (1) cefuroxime axetil, 250 mg orally every 12 hours (21 patients); (2) cefuroxime axetil, 500 mg orally every 12 hours (21 patients); and (3) cefaclor, 500 mg orally every eight hours (19 patients). Of these 61 patients, 80% were male, with a mean age of 59.5 years; 56% had acute pneumonia, and the remainder had an acute bronchitis. Causative pathogens included typical respiratory tract pathogens. Overall, 23 of 27 patients with bronchitis were clinically cured at the end of therapy. Thirty-one of 34 pneumonias were clinically cured or improved at the end of therapy; the three pneumonia treatment failures occurred in the lower dose cefuroxime (n = 2) and cefaclor (n = 1) treatment groups. Overall, bacteriologic cure occurred in 86% of patients treated with 500 mg of cefuroxime axetil compared with 60% of cefaclor-treated patients. Adverse clinical effects were uncommon. From this study, it was concluded that cefuroxime given every 12 hours is at least as clinically efficacious as cefaclor; it is a new oral cephalosporin with pharmacologic and bacterial spectrum advantages over many older agents.
