Which of the following methods describes how a patient should take a controlled-release product?

This method is associated with buccal administration, which allows for the absorption of medication through the mucous membranes. However, controlled-release products are not formulated for absorption via this route, as they rely on gastrointestinal processing for proper release and effect.

Sublingual administration, where the medication is placed under the tongue, allows for rapid absorption directly into the bloodstream. Controlled-release products are not designed for this method since they require a specific release mechanism that occurs in the gastrointestinal tract.

Dissolving a controlled-release product in liquid would disrupt its intended formulation and could lead to rapid release of the active ingredient instead of the controlled release that is necessary for therapeutic effectiveness. Such products are formulated to maintain their integrity until they reach the appropriate site in the digestive system.
