Abstract
There are disclosed herein a gelatin coating composition which comprises succinated gelatin as the main component and polyethylene glycol, and a hard gelatin capsule formed from said gelatin coating composition. The hard gelatin capsule has sufficient mechanical strength for filling operation. Moreover, it does not become insoluble due to reaction with a special drug having an aldehyde group filled therein. Therefore, it can be used for various drugs, especially macrolide antibiotics for which conventional hard gelatin capsules are inadequate.
