| titleOfInvention | Substrates providing multiple releases of active agents |
| abstract | The present invention includes a polymeric substrate that provides multiple release of the active agent. A second polymer matrix layer containing a second active agent disposed therein, and a second polymer matrix layer disposed between the first polymer matrix layer and the second polymer matrix layer A substrate for multi-stage delivery of an active agent having a coacervate layer is provided. The selected first and second activators are included in the first and second polymer matrices such that the first and second polymeric matrices are dissolved and the active agent is released. Multi-step activator release is achieved by constructing a multi-layered polymer matrix that contains an active agent and is formed of a polymer having different solubility characteristics or containing an active agent at different concentration levels. |
