A novel elastomeric composition of matter comprises a rubber latex and a masterbatch comprising a therapeutic agent in a therapeutically effective amount, a carrier component, titanium dioxide, and clay. A process for the preparation of a novel elastomeric composition of matter containing a therapeutic agent includes the steps of preparaing a masterbatch containing a therapeutic agent, adding the masterbatch to a rubber latex and thereafter forming and curing a desired product therefrom. The composition is useful in the manufacture of rubber goods such as surgical and medical products which can be single or multilayered.
