(R)-2-(2-OXO-PYRROLIDIN-1-YL)-BUTYRAMIDE Usage And Synthesis

Uses

(R)-Levetiracetam [REV] (Levetiracetam EP Impurity D), is the enantiomer to Levetiracetam [LEV] (L331500), the antiepileptic drug that is highly enantioselective. It is apparent that [LEV] is more potent than [REV] in terms of antiepileptic potency.
