[Cannabis use in Epilepsy. Current situation in Argentina and abroad].

Although at present we have over 20 different types of drugs for epilepsy, 30 to 40% of patients continue to have seizures. Preliminary data from human studies suggest that cannabis, cannabidiol in particular, is effective in the treatment of some patients with epilepsy. However, the available data are limited and do not allow defnitive conclusions. Only randomized clinical trials with controlled double-blind, placebo-controlled utilizing secure preparations and one or more cannabinoids, will provide comprehensive information on the effcacy and safety of use. In order to perform these trials it is necessary to have legislation authorizing the use of cannabis on epilepsy.
