1. In 33 epileptic patients on phenytoin monotherapy. the CSF levels of the drug constituted 12.5( 5% (range 5.4 to 23%) of the serum levels.
2. The mean serum levels of the drug (13.356 (g/ml) in controlled patients (17) were not significantly different from the levels in uncontrolled patients (11). The mean CSF levels in uncontrolled patients (0.92(O.32) were significantly lower (p<0.001) than those in controlled patients (1.49(0.59).
3. In 5 patients who developed toxicity, the serum (27.3 ( 10.6) as well CSF (5.3 ( 1.8) levels of phenytoin were significantly higher than those of uncontrolled and controlled (without toxicity) patients.
