S. Arakawa et S. Kamidono, CLINICAL-EVALUATION OF DRUG EFFICACY IN UTI IN MEN - THE SIGNIFICANCEOF BACTERIAL ELIMINATION ON DAY ONE, Infection, 22, 1994, pp. 190000023-190000026
With the purpose of assessing whether the effect of a drug at an early
stage of administration could serve to predict efficacy at the end of
drug treatment, a cephem antibiotic was administered for 5 days (days
0-4) by injection in males with complicated UTI. Results showed that
the bacteriological effect on day 1 was reflected in the overall clini
cal efficacy on day 5. The activity of an antibacterial agent appeared
to be reflected in the ability to eliminate bacteria 1 to 2 days afte
r the start of drug administration.
