Four-hundred and eighty-four patients with acute laryngitis were exami
ned before and after treatment with fusafungin under phase IV conditio
ns. After one week of therapy such complaints as hoarseness, sore thro
at and difficulties in swallowing were improved in about 90% of the pa
tients, while the leading complaint of ''hoarseness'' had disappeared
in 60%. Inflammatory findings, documented by a physician, showed compa
rable results. An analysis of subgroups (ineffectively treated patient
s and patients with long-lasting symptoms and complaints) shows that f
usafungin was effective therapeutically for treating for acute laryngi
tis. This study also shows that the generally accepted high rate of sp
ontaneous recovery does not exist.
