| titleOfInvention | Device for the controlled release of drugs with donnanlike modulation by charged insoluble resins |
| abstract | The instant invention relates to a drug-delivery device for the controlled release of a therapeutically active ingredient into an environment of use which comprises:n (A) a core composition comprisingn (a) a water insoluble, non-diffusible charged resin entity, and (b) a diffusible water soluble ionizable therapeutically active ingredient carrying the same charge as said resin entity; and (B) an imperforate water insoluble wall surrounding said core composition and prepared from a semipermeable material substantially impermeable to core composition and permeable to the passage of an external fluid in the environment of use, with said wall having a means for release of the therapeutic agent through the water insoluble wall; or (C) a water insoluble wall surrounding said core composition and prepared from (i) a polymer material that is permeable to water but substantially impermeable to solute and (ii) 0.1 to 75% by weight, based on the total weight of (i) and (ii), of at least one water leachable pore forming additive dispersed throughout said wall. |
