  • Method for controlling fertility
    Patent number: 5842476
    Abstract: An osmotic device is disclosed comprising an exterior coat comprising an estrogenic and a progestogenic steroid that are delivered immediately as a contraceptive pair for fertility regulation in a female, and a compartment comprising an estrogenic steroid that is delivered at a controlled rate over a prolonged period of time for fertility regulation in a female.

  • Transdermal contraceptive formulations methods and devices
    Patent number: 5512292
    Abstract: The present invention provides compositions and methods for the transdermal administration of a contraceptively effective amount of gestodene and estrogen, such as ethinyl estradiol, in combination, together with a suitable permeation enhancer. The amount of the estrogen codelivered is kept at an about constant and contraceptively effective rate while the amount of gestogen codelivered varies depending on the phase of the menstrual cycle but remains at a contraceptively effective rate. The size of the system may also vary depending on the amount of gestogeno be delivered.

  • Segmented device for simultaneous delivery of multiple beneficial agents
    Patent number: 5443461
    Abstract: Diffusional delivery devices are constructed in two or more compartments, each containing a separate drug or other beneficial agent, and each arranged to permit diffusion of the agent out of the device through an individually-characterized agent-permeable wall segment. The diffusion rates of the various agents relative to one another are set and controlled by the parameters of the individual wall segments, such as the surface area of the wall segment, the average thickness of the wall segment, and the permeability of the wall segment for the particular agent. The permeability may be varied by variations in the chemical composition of the wall segment. Using these parameters rather than blending the agents at calculated ratios in a single formulation for diffusion through a single wall permits a wider range of, and greater flexibility in, variation between the diffusion rates of the different agents. This is of value when the simultaneous administration of agents at a specified ratio is desired.
