[Studies on absorption and excretion of cyclacillin granules (vastcillin granules 'Takeda') (author's transl)].

Vastcillin granules 'Takeda', a cyclacillin (AC-PC) preparation for children were orally administered to nine children at a single dose of 10 mg/kg and its blood concentrations and urinary excretion were studied.
