Current status and challenges of antibiotic treatment in Japan The use of antibiotics in Japan is not particularly higher compared to that in Europe or the USA. However, in Japan oral antibiotics account for 92.4% of the total daily usage, and consists of third generation cephalosporins, macrolides and fluoroquinolone derivatives, which are so-called broad-spectrum antibiotics. Therefore, it is considered that the problem in Japan is the use of such broad-spectrum oral antibiotics (1). Higashi, et al. examined the national prescription database for the period from January to March 2005 and reported that approximately 60% of patients with non-bacterial upper respiratory tract infections were given antibiotics. The breakdown of the prescriptions was third generation cephalosporins (46%), macrolides (27%) and quinolones (16%) in descending order of frequency, and were prescribed more often at clinics than hospitals (2). Antibiotics may be prescribed to patients with the common cold for the purpose of pneumonia prophylaxis. Regarding this, a study was conducted to investigate how many patients with acute respiratory tract infection, including those with the common cold, need to be treated with antibiotics to prevent one patient from developing complications including pneumonia (3). The results showed that one case of complications could be prevented if 4,000 patients with acute respiratory tract infection would be given antibiotics. Considering the cost of antibiotics prescribed to 4,000 patients and the risks of adverse drug reactions and resistant bacteria, the prophylactic use of antibiotics to (71)
