tebipenem and Pneumonia

In November 2004, "Guidelines for the Management of Respiratory Infectious Diseases in Children in Japan" was published ahead of the rest of the world, by Japanese Society of Pediatric Pulmonology/Japanese Society for Pediatric Infectious Diseases, based on the data on causative organisms in the lower respiratory tract. In its 2011 version, classification of the severity of pneumonia was renewed based on the latest information. As a result, many types of pneumonia in children are now classified as mild or moderate. This means that many patients who might have conventionally required hospital treatment can now be managed on an outpatient basis. The reason for realization of the wider range of outpatient treatment is the availability of two new oral antimicrobial agents, tebipenem pivoxil and tosufloxacin tosilate hydrate, for the treatment of infections in children. Analysis of data on medical expenses shows a decreased rate of hospitalization due to pneumonia year by year after launch of these two drugs, suggesting that these drugs have contributed to wider range of outpatient treatment. This manuscript discusses the effect of tebipenem pivoxil and tosufloxacin tosilate hydrate in the treatment of pneumonia.

We evaluated the efficacy and safety of a 3-day treatment regimen of tebipenem pivoxil for pediatric community-acquired pneumonia. Tebipenem pivoxil was administered to 49 patients, and its effectiveness was evaluated in 36 patients 2-4 days after initiation of treatment. Thirty-two patients were cured 7-15 days after initiation of treatment. Body temperature was significantly lower on the day following initial administration (median 38.8 to 37.0 °C, n = 33). Leukocyte counts and C-reactive protein levels were significantly reduced by Day 2-4 of treatment (median 16,100 to 7800 white blood cells/μL, and 5.6 to 1.5 mg/dL, respectively; n = 28). Six of the 49 patients had mild diarrhea. Thus, we concluded that 3-day treatment with tebipenem pivoxil was safe and efficacious for treating pediatric community-acquired pneumonia.

A 4mg/kg dose of tebipenem pivoxil (TBPM-PI) was administered twice daily for 3 days to 34 pediatric patients with pneumonia who had chest X-ray findings indicative of pneumonia and CRP values of at least 3.0 mg/dL. The clinical effects of this regimen were evaluated by retrospectively examining medical charts for the period from April 2012 to March 2015. The patients were 6 months to 8 years old, with serum CRP values ranging from 3.06 to 14.25 mg/dL. Fever resolved within 24 hours and respiratory symptoms improved within 3 to 5 days after the start of treatment in all 34 patients. Although CRP was positive in 28 of 30 patients at the end of the treatment period, none of these children showed worsening of pneumonia. Eight patients (23.5%) experienced adverse drug reactions including diarrhea. These results indicate that a 3-day course of TBPM-PI is useful for treating pediatric pneumonia.

We conducted a postmarketing surveillance of tebipenem pivoxil granules (Orapenem® fine granules 10% for pediatric), an oral carbapenem antibacterial agent, between April 2010 and March 2013 to evaluate the safety and efficacy in patients with pneumonia or otitis media, or sinusitis Of 3,547 patients enrolled, 3,540 from whom survey forms were collected were analyzed. Of these 3,540 patients, there were a total of 3,331 patients included in the safety analysis, 2,844 in the efficacy analysis, 2,769 in the clinical efficacy analysis, and 461 in the bacteriological efficacy analysis. The incidence of adverse drug reactions (ADRs) was 9.97% (332/3,331 patients), and the major ADRs were gastrointestinal disorders including diarrhoea in 317 patients (9.52%). Diarrhoea was reported in 313 patients (316 events), which were not clinically significant and 94.9% (297/313 patients) were recovery and/or remission. The overall clinical efficacy rate was 94.0% (2,604/2,769 patients). The clinical efficacy rate by the type of infection was 95.6% (415/434 patients) for pneumonia, 93.7% (1,389/1,482 patients) for otitis media and 93.6% (659/704 patients) for sinusitis. The eradication rate of Streptococcus pneumoniae, Haemophilus influenzae and Moraxella (Branhamella) catarrhalis which are major causative organisms in pediatric infection of pneumonia, otitis media and sinusitis were 94.4% (134/142 strains), 92.2% (130/141 strains) and 97.8% (45/46 strains), respectively. The compliance was good in 83.1% of the patients (2,767/3,331 patients). Overall, Orapenem® fine granules 10% for pediatric showed good safety, efficacy, and compliance. These results indicate that Orapenem® fine granules 10% for pediatric is a useful agent in pediatrics with pneumonia or otitis media, or sinusitis.
