Abstract (en)

[origin: FR2764292A1] The invention concerns the use of teracyclic derivatives of general formula (I) in which independently of one another: R1 is a hydrogen atom, a halogen atom, a C1-C5 alkyl radical, a C1-C5 alkoxy radical or OH, a nitro radical, an amino radical, a C1-C5 amino alkyl radical, a C1-C5 amino dialkyl radical, a C1-C5 thioalkyl radical or SH; R2 is a hydrogen atom, a halogen atom, a C1-C5 alkyl radical, a C1-C5 alkoxy radical, or OH, a nitro radical, an amino radical, a C1-C5 alkyl amino radical, a C1-C5 amino dialkyl radical, a C1-C5 thioalkyl radical or SH; R3 is a hydrogen atom, a halogen atom, a C1-C5 alkyl radical, a C1-C5 alkoxy radical or OH, a nitro radical, an amino radical, a C1-C5 amino alkyl radical, a C-C amino dialkyl radical, a C1-C5 amino thioalkyl radical or SH; n and m are either equal to 0 or to 1, but not independently of each other such that if n is equal to 1 then m is equal to 0, and if n is equal to 0 then m is equal to 1, for obtaining a medicine for treating functional and organic venous insufficiency.
