A pharmaceutical delivery system enabling the oral transmucosal administration of active pharmaceutical agents in a situation where rapid transmucosal administration is preferred to prevent the delay and decomposition of the agents in passing through the intestinal tract. The delivery system comprises a supportive substrate with bilateral lingual vestibular flanges connected at the anterior midline to form a ‘U’ like shape for fitting in the potential space of the bilateral lingual vestibules, and further comprising a handle or tab for holding the device in the mouth of a patient with altered consciousness to prevent aspiration or premature swallowing. The pharmaceutical dosage-form is formulated and shaped to contact the mucosal tissues and may include mucoadhesive compounds, retentive compounds, and/or additional payload enhancers, such as permeation enhancers and flavor enhancers.
