An arrangement for controlling microbial content or growth in a fluid, comprising (a) a zeolite with micro-pores charged with an agent having affinity to the zeolite micro-pores and having antiseptic properties and (b) the fluid, the zeolite and the fluid being enclosed by, at least partially in contact, or being arranged for being brought at least partially in contact. The fluid contains molecules being larger than the micro-pores of the zeolite and having less affinity, as defined, to the zeolite than the agent. The fluid may contain a therapeutically active compound or composition in a therapeutically effective amount and concentration and that the total amount of agent in the zeolite is larger than an amount corresponding to an antiseptic level for the fluid. Also disclosed are methods, uses and zeolites for control of microbial content or growth in a fluid. |
