Prostaglandin E2 on the electroencephalogram

Abstract

Present study was prompted by the report from another center on the occasional occurrence of convulsions and abnormal electroencephalogram (E.E.G.) patterns in women aborted with intraamniotic prostaglandin F2α (PGF2α). Fifty four subjects were investigated by means of an E.E.G. taken before and after initiation of PGE2 administration. They included pregnant and non-pregnant patients, nearly half (23) of whom were known epileptics. One seizure was observed during PG administration in a man with daily psychomotor attacks who had not taken his anticonvulsants on the day the test was performed. PGE2 caused no alteration of the E.E.G. in subjects with a normal control tracing; in those with an abnormal E.E.G., a deterioration was seen in one and an improvement in three. It is concluded that PGE2 is not epileptogenic at doses required for termination of pregnancy.
