[Investigations on the penetration of cefamandole into spinal fluid (author's transl)].

In 20 test persons spinal fluid was taken at intervals of 15, 30, 60 and 90 minutes after a single injection of 40 mg cefamandole/kg body weight in order to determine the levels of the active substance. Whereas in serum an average peak value of 248 mcg/ml was determined after ten minutes, there was no trace at all of cefamandole in the spinal fluid.
