The present invention includes a) a zeolite having a micro-pore filled with a preservative having affinity for zeolite micro-pores and having antiseptic properties, and b) a fluid, wherein the zeolite and the fluid are enclosed in at least partial contact with the zeolite. Or to at least partially contacted arrangements to control microbial content or growth in the fluid. The fluid contains molecules that are larger than the micro-pores of the zeolite and have a smaller affinity as defined for the zeolite than for the preservative. The fluid may contain a therapeutically active compound or composition in a therapeutically effective amount and concentration, wherein the total amount of preservative in the zeolite is greater than the amount corresponding to the preservative level for the fluid. The invention also describes methods, uses and zeolites for controlling microbial content or growth in fluids. |
