Dissolution failure

The tablet or capsule did not dissolve within specification. Dissolution controls how much drug the body absorbs; a failure can change the effective dose.

405 FDA drug recalls with this cause, newest first.

These recalls happen when a tablet or capsule does not dissolve the way its specification requires. Because dissolution controls how the drug is released, a failure can mean a patient absorbs it too slowly, too quickly, or not at all - a particular concern for extended-release products, where the release profile is the whole point.
