Abstract
A process for the manufacture of a prophylactic device having contained therein at least one pharmaceutically active substance, comprising: PA1 forming a first layer of elastomeric material into the desired shape of the prophylactic device; PA1 prevulcanizing the first layer; PA1 applying to one side of the first layer a layer of microcapsules having at least one pharmaceutically active substance encapsulated therein; PA1 depositing on the coating of microcapsules a second layer of elastomeric material; and PA1 vulcanizing the first and second layers of elastomeric material. The device may be in the form of a contraceptive sheath, finger stall or glove, and protects the user from contamination by various germs, viruses, fungi and other pathogens in the whole area of the body covered by the device.
