An open-label, randomized study was conducted in 298 children older th
an 18 months (211 evalualbe) to compare seven days of penicillin V wit
h five days of spiramycin for the treatment of pharyngitis due to grou
p A streptococcus. There were no significant differences between study
populations. Clinical and bacteriological results were similar in the
two groups, even for the intention-to-treat analysis. Safety was also
similar, as well as relapse rates, reinfection rates, and proportions
of asymptomatic carriers on D10 and D30. These data demonstrate that
five-day-twice-daily treatment with spiramycin is effective in strepto
coccal pharyngitis and may be a good alternative in patients with cont
raindications to beta-lactams.
