Abstract
New tetrazole derivatives, characterized in that they correspond to the formula: ##STR1## in which R.sub.1 represents: either a hydrogen atom in any one of the positions 1 to 5 of the tetrazole nucleus, R designating a branched alkyl group comprising at least 5 carbon atoms or a branched alkenyl group, or a methyl group in position 2(3) of the tetrazole nucleus, R representing the (1-propyl)n butyl chain. These new derivatives are useful as medicaments, more especially for their anti-epileptic action.
