Cefaclor concentration in radicular granuloma after a single oral administration.
1. Cefaclor concentrations in radicular granuloma and serum in nonfasting patients after a single oral administration of 500-mg cefaclor were assayed. 2. The mean peak concentrations in radicular granuloma and serum were 2.57 mcg/g and 7.41 mcg/ ml, respectively. The mean ratio of granuloma/serum concentration at the peak time was 0.35. 3. All cefaclor concentrations in radicular granuloma at the peak time exceeded the minimal inhibitory concentration for 90% of oral streptococci (1 mcg/ml) isolated from odontogenic infection.
