[Clinical studies on SY5555 in pediatrics].

SY5555 in dry syrup (powder which is dissolved before use) or tablet form was given orally to 21 children with acute bacterial infections including 4 with acute pharyngitis, 5 with acute tonsillitis, 7 with acute bronchitis, 2 with acute gastroenteritis, 1 each with scarlet fever, acute lymphadenitis and urinary tract infection. Good to excellent clinical responses were obtained in all of the 21 patients and 8 of 11 strains found as causative organisms in these cases were eradicated and 3 strains were decreased. Loose stools were observed in 3 cases and eosinophilia was observed in 1 case. From the above clinical results, it appears that SY5555 is a useful antibiotic for the treatment of pediatric patients with various bacterial infections.
