Delivery Profiles

Vyteris’ active patch patented technology works by applying a positive charge to the drug-holding reservoir of the patch. As most drug molecules are positively charged, the two like-charges repel, forcing the drug molecules out of the reservoir and into the skin. By controlling the intensity and duration of the positive charge applied, the smart patch controls whether the drug delivery is topical, or whether the drug molecules are pushed deeper into the skin, where they enter the body’s circulatory system directly.

The timing of drug delivery can also be precisely controlled. The drug delivery profile can be accurately programmed to mimic that of intravenous infusion or to release the drug for rapid onset. The system can also be preprogrammed to automatically release the drug at regularly timed intervals, avoiding problems of patient compliance with multiple doses.

Or the Vyteris active patch can be programmed to deliver a bolus of drug on demand — useful, for example, with pain medications.

In fact, drug delivery with the Vyteris active patch system can be programmed to meet the needs of the given medical situation. Never before has there been such potential for non-invasive, controlled, and customized drug delivery.
