Sustained release drug-resin complexes |
摘要 |
Disclosed are oral pharmaceutical preparations which comprise a pharmacologically active drug bound to small particles of an ion-exchange resin to provide a drug-resin complex having a drug content above a specified value. The drug-resin complex is subsequently coated with a water-permeable diffusion barrier coating that is insoluble in gastrointestinal fluids thereby providing a controllable sustained release of drug under conditions encountered in the gastrointestinal tract. |
