Abstract
The frequency of prescription and the purchase amounts of new quinolone agents (NQs) and oral antibiotics were surveyed in 9 hospitals of the 11 national university dental hospitals in Japan.
Average numbers of antibiotics and NQs adopted in the 9 hospitals were 25.5 and 4.0, respectively. The ratio of antibiotics to NQs was 6.4 to 1.0. The purchase amounts of oral antibiotics and NQs of the 9 hospitals per year were 1, 390, 000 and 80, 000 tablets, respectively. Of these antimicrobial agents, a large amount of β-lactams of 1, 200, 000 tablets were purchased, followed by NQs of 80, 000 tablets, which exceeded macrolides of 50, 000 tablets. As for the brand, Cefaclor was the largest purchase amount of antibiotics at about 500, 000 tablets, and the largest for NQs was Levofloxacin at about 40, 000 tablets. The proportion of NQs to total oral antimicrobial agents, including antibiotics, was 6%.
