[Activation with amitriptyline: electroclinical comments on 120 epileptic patients (author transl's)]

The sleep-inducing and epileptogenic effects of amitripyline (0.5 mg/kg i.m.) were studied in 120 epileptic patients. Sleep occurred in 94 p. 100 of the patients: 92 p. 100 showed stages I and II, 42 p. 100 also showed stages III and IV, but only 12 p. 100 showed REM. Major activation of inter-ictal abnormalities occurred in 41 p. 100 and seizures were provoked in 17 patients (14 p. 100). Neutral results were obtained in 23 p. 100 of cases. The results obtained and the complete absence of drawbacks recommend amitriptyline for use in studying epileptic patients, at least before turning to other pharmacological techniques which are more dangerous and probably less reliable.
