| 摘要 |
This invention relates to polymeric complexes of drugs to be employed as (or in) sustained release-formulations comprising a cationic active agent, and a polyanionic water soluble complexing polymer of sufficient molecular weight that it forms a gel when mixed with said active agent. The invention also relates to the manufacture of such sustained release compositions and their many uses. Also included is a molded prosthesis comprising a prosthesis including a sustained release composition comprising a cationic anti-infective and a complexing polymer.
