Peak blood level of cephalexin was obtained at 4 hours after the administration of S-6437 as opposed to 2 hours after regular cephalexin. Peak blood level with regular cephalexin was higher than that with S-6437. Blood levels with S-6437, however, stayed for longer period than those with regular cephalexin. Mean urinary recovery within 12 hours after the administration of S-6437 after meal and during meal were 57.1 and 69.3%, respectively. S-6437 was studied in 23 pediatric patients, 7 with acute tonsillitis, 15 with acute cystitis and 1 with cellulitis. They were orally given 400 to 1,200 mg/day of S-6437 in two divided doses at 30 minutes after meal for 4 approximately 12 days. Of the 23 patients, 18 responded to the drug but 5 did not respond. As for side effects, eruption and diarrhea were observed in 1 and 2 patients, respectively. No other side effects were found.
