Abstract:
After an intravenous drip infusion of 1 g or 2 g of ceftriaxone (CTRX), its concentrations in serum and tissue were determined using the bioassay for 18 surgical patients with chronic paranasal sinusitis. 1. The serum levels observed at 75-105, 135-165, 195-225 minutes after an intravenous drip infusion of 1 g, averaged 98 +/- 38, 92 +/- 13 and 73 +/- 13 micrograms/ml, respectively. 2. The tissue levels at 75-105, 135-165, 195-225 minutes after an intravenous drip infusion of 1 g, averaged 27 +/- 13, 27 +/- 7 and 25 +/- 9 micrograms/g. 3. CTRX appears to be a useful drug for the treatment of chronic paranasal sinusitis.
