The invention relates to a material for producing products (1) having fibrinolytic and/or antibacterial properties. Said material has at least one matrix (2), which is compatible with body tissue and in which a molecular sieve is incorporated. Said molecular sieve is loaded with: at least one active substance (Z) having a fibrinolytic or antibacterial effect; or at least one first active substance (Z1) having a fibrinolytic effect and a second active substance (Z2) having an antibacterial effect. The corresponding molecular sieve/active substance adduct (3) releases the active substance(s) in conjunction with the aqueous body fluid when the matrix (2) is in contact with the body tissue (4). The inventive material is characterized in that the molecular sieve/active substance adduct (3) additionally contains water of crystallization to such an extent that the molecular sieve is partially dehydrated with regard to a sufficient basic molar quantity (m) of water of crystallization. The molecular sieve is loaded with the reduced molar quantity (m') of water of crystallization with the active substance(s) (Z, Z1, Z2) so that an adsorption of water with the desorption of the corresponding active substance occurs when the matrix (2) is in contact with the body tissue (4), whereby the water of crystallization of the molecular sieve increases. The invention also relates to an advantageous method for producing the inventive active substance.
