An improved condom is provided by coating the inner and or outer surface of the condom base with a dissolvable element containing an agent material for delivering the agent material during sexual intercourse. The dissolvable element is made of dissolvable polymer material and/or complex carbohydrate material which are food grade materials and have selected dissolution properties, such that it remains in substantially solid form before use, and dissolves due to human body temperatures and moisture during use to release the agent material in a desired timed release and dosage. The dissolvable element is preferably a film made of polyvinyl alcohol, polyethylene oxide, hydroxypropyl methyl cellulose and/or carboxymethyl cellulose. The dissolvable element may be formed as a single layer of film or a laminate of different film layers for compound release properties. The dissolvable element is at least partially foamed using inert gases, such as nitrogen, to adjust its dissolution properties. The agent material can be selected from the group consisting of spermicides, anti-infectives, anti-inflammatories, antibodies, steroids, vasoactive agents, sensory modifying agents, anti-oxidants, preservatives, plasticizers and mixtures thereof. The condoms can be used for sexual intercourse involving penis with vagina, rectum or mouth.
A condom capable of delivering at least one agent material into a body cavity characterized by improved heat and humidity stability of up to 140° F. and 97% respectively, comprising a condom base having an inner and outer surface coated on at least one surface thereof with at least one dissolvable film from a member selected from the group consisting of polyvinyl alcohol, polyethylene oxide, hydroxyl propyl methyl cellulose and mixtures thereof, at least one of said films having distributed throughout an inert gas, at least one of said films incorporating at least one agent material, said film dissolving at the temperature of said body cavity and in the presence of the moisture naturally present in the said body cavity to release said agent material.
A method of manufacturing a condom having an interior surface and an exterior surface which comprises coating at least one of said surfaces with a coating comprising a dissolvable film formed from a member selected from the group consisting of polyvinyl alcohol, polyethylene oxide, hydroxyl propyl methyl cellulose and mixtures thereof incorporating at least one active agent material selected from the group consisting of spermicides, anti-infectives, antibodies, steroids, vasoactive agents and mixtures thereof.
