Oral transmucosal methadone

摘要

Pharmaceutical compositions for oral-transmucosally administering methadone. For oral transmucosal delivery, the compositions comprise an oral dissolution agent and methadone in a dosage formulation. The dissolution agent generally causes the formulation to break down or dissolve in the oral cavity. The formulation is buffered to a pH of at least 6 for substantial absorption of the methadone through the oral mucosal tissue from the dissolved dosage form.
