title: [Experimental and clinical evaluation of an ampicillin suppository (KS-R1) in children].
abstract: Plasma levels of ampicillin (ABPC) after the single rectal insertion of KS-R1 at doses of 125 and 250 mg in 154 children reached a peak at 11 approximately 15 minutes in children of age less than 1 year old, at 16 approximately 20 minutes in children of 1 approximately 3 years, 4 approximately 6 years and more than 7 years old with the highest levels of 11.50, 8.69, 10.33 and 8.30 micrograms/ml, respectively. Highest plasma levels of ABPC were 6.48, 8.00, 12.32 and 17.83 micrograms/ml by the administration of KS-R1 at doses of less than 10.9 mg/kg, 11.0 approximately 15.9, 16.0 approximately 20.9 mg/kg and more than 21.0 mg/kg, respectively, with dose-dependent response which were observed at 11 approximately 15 minutes or 16 approximately 20 minutes. There was no difference of plasma levels between the administration of 125 and 250 mg of KS-R1. The pain of insertion was observed in 0.6% of total 167 cases, the feeling of defecation in 2.4% and the discharge of suppository or its dissolved material or defecation within 30 minutes after insertion in 12.6%, without the influence of patients ages and dosage level. These figures were almost the same as those after the insertion of other suppositories such as erythromycin suppository or antipyretic suppository. Clinical effectiveness of KS-R1 was examined in 51 childish patients with various infections. KS-R1 was rectally given to them at doses of average 41.6 mg/kg/day divided into 3 to 4 times for 7 days. All cases showed excellent and good effects. Bacteriologically, all pathogens which were isolated from 12 patients were eradicated.
