Abstract

This invention relates to coated digestive enzyme preparations and enzyme delivery systems and pharmaceutical compositions comprising the preparations. This invention further relates to methods of preparation and use of the systems, pharmaceutical compositions and preparations to treat persons having ADD, ADHD, autism, cystic fibrosis and other behavioral and neurological disorders.

Claims
