Summary for Patent: 7,682,628
Title:Compositions for delivering hypnotic agents across the oral mucosa and methods of use thereof
Abstract: The present invention provides novel compositions for the delivery of a hypnotic agent across the oral mucosa. In particular, the buffer system in the compositions of the present invention raises the pH of saliva to a pH greater than about 7.8, thereby facilitating the substantially complete conversion of the hypnotic agent from its ionized to its un-ionized form. As a result, the dose of hypnotic agent is rapidly and efficiently absorbed by the oral mucosa with surprisingly low inter-subject variability. Furthermore, delivery of the hypnotic agent across the oral mucosa advantageously bypasses hepatic first pass metabolism of the drug and avoids enzymatic degradation of the drug within the gastrointestinal tract. Methods for using the compositions of the present invention for treating sleep disorders such as insomnia are also provided.
