| Zusammenfassung: | Drug dispensers comprising a flat body composed of a drug solute phase dispersed in a continuous polymer matrix phase in which the release rate of drug from the body is substantially constant and is controlled by the rate at which the drug solute phase dissolves in the continuous polymer matrix phase. Such control and constancy are realized by establishing specific correlations between the diffusion coefficient, dissolution rate constant, and thickness of the body. |
