The invention relates to 2-Heteroaryl-imidazotriazinones, processes for their preparation and their use in medicaments, esp. for the treatment and/or prophylaxis of inflammatory processes and/or immune diseases. The present invention relates to compounds of the general formula (I) in which R1 denotes 5- to 10-membered heteroaryl, which is optionally substituted by identical or different residues selected from the group consisting of halogen, (C1-C4)-alkyl, trifluoromthyl, cyano, nitro und trifluoromethoxy, denotes 3- to 10-membered carbocyclyl or carbon-bonded, 4- to 10-membered heterocyclyl, whereby carbocyclyl and heterocyclyl are optionally substituted by identical or different residues selected from the group consisting of (C1-C6)-aldyl, (C1-C6)-aldoxy, hydroxy, halogen, trifluoromethyl and oxo, or denotes (C2-C10)-alkyl, which is optionally substituted by identical or different residues selected from the group the group consisting of (C1-C6)-alkoxy, hydroxy, halogen, 3- to 10-membered carbocyclyl and oxo.
