The mother or father drug leaves quickly while the metabolites persist, giving a protracted tail of outcome. That tail can be a disadvantage in certain options and precisely the point in Many others.

when compared with newer anticonvulsants, it is not a servicing drug. Its spot is stopping an party in development.
Price is often a practical element that retains it in use around the globe. it really is cheap, extensively obtainable and effectively characterised immediately after 6 a long time of clinical knowledge.
