DRUG PARTICLES HAVING CONSTANT RELEASE |
| 摘要 |
Drug particles are disclosed which reduce the variation in dissolution rate with time frequently found with sustained-release dosage forms. This is achieved by coating the drug particle with an inner coating of an enteric material and an outer coating of a material which is insoluble at any pH and acts as a diffusion barrier for the drug active. |
