[Clinical experience with S-6436 in urinary tract infections (author's transl)].

S-6436 is a new preparation of sustained release cephalexin. Twenty-eight patients with urinary tract infections were orally given 500mg of S-6436 twice a day for about 7 days, and the following results were obtained: 1) Excellent clinical responses were observed in 8 cases, good in 18 cases and failure in 2 cases. Effectiveness was 93%. 2) As for the side effect, gastrointestinal symptoms were observed in one case out of 28 cases, but they disappeared after the completion of the treatment. No other side effects due to S-6436 were observed. S-6436 has as much effectiveness and safety as compared with usual cephalexin preparations. The frequency of the administration of S-6436 is twice a day, which means that S-6436 is more convenient in giving it to patients than usual cephalexin preparations.
