A double blind study of single dose azithromycin and doxycycline in the treatment of chlamydial urethritis in males.
OBJECTIVE
To compare the efficacy and safety of azithromycin and doxycycline in the treatment of males with uncomplicated urethritis caused by chlamydia trachomatis.


METHODS
A multicentre, double-blind, randomised treatment study.


METHODS
130 male outpatients with clinical signs and symptoms of urethritis.


METHODS
STD clinics at four Norwegian University Hospitals.


METHODS
Patients were randomly allocated to 1000 mg azithromycin as single dose or doxycycline 100 mg twice daily for 7 days. Clinical, bacteriological and safety assessments were made at entry and after 1 and 2 weeks. Safety data were also repeated after 4 weeks.


RESULTS
Demographic data were similar in both groups. At the week 1 assessment bacteriological eradication was achieved in 44 of 44 evaluable azithromycintreated patients and in 42 of 42 in the doxycycline group. At the week 2 assessment the corresponding figures were 35 of 35 and 34 of 34 respectively.


CONCLUSIONS
Azithromycin 1000 mg single dose was as effective as doxycycline 100 mg twice daily for 7 days in male patients with chlamydial urethritis.
