A method of preventing epileptic seizures in a human or lower animal subject susceptible to said seizures, comprising systemically administering to said subject a safe and effective amount of a compound of the formula: ##STR1## wherein (a) X is halo or nil, and Y is a substituent selected from the group consisting of unsubstituted or halogen-substituted methyl, halo, nitro, amino, and methoxy; and (b) R is R.sup.1 C(O)OH, R.sup.1 C(O)N(R.sup.2).sub.2, or R.sup.1 N(R.sup.2).sub.2 ; where R.sup.1 is C.sub.1 -C.sub.3 alkylene which is unsubstituted or substituted with C.sub.1 -C.sub.2 alkyl; and each R.sup.2 is, independently, hydrogen or lower alkyl; or both R.sup.2 groups are connected to form a saturated 5- or 6-membered heterocycle containing 1 or 2 heteroatoms, wherein one of which is nitrogen and the other is selected from oxygen and nitrogen and said heterocycle is unsubstituted or substituted with lower alkyl or hydroxy-substituted lower alkyl; or a pharmaceutically-acceptable salt thereof. Preferably X is halo.
