Meningeal penetration of apalcillin in man.
We have used high performance liquid chromatography to evaluate the meningeal penetration of apalcillin. In subjects without meningitis the penetration was poor and the levels obtained did not exceed 1.75 mg/l. In cases of meningitis, when the spinal fluid albumin level was greater than 0.60 g/l, the levels varied from 5 to 30 mg/l. These figures are in accord with those obtained in cases of experimental meningitis. A dosage of 200 mg/kg/day should allow the treatment of meningitis due to sensitive bacteria and in particular due to Pseudomonas aeruginosa.
