Which of the following are examples of Oral Extended Release Forms?

• A. Plateau caps, Sequels, Extentabe, Repetabs
• B. Immediate-release tablets
• C. Lozenges that dissolve in mouth
• D. Buccal patches

Answer: (A)

Oral extended-release forms are designed to release the drug slowly as it passes through the gastrointestinal tract, giving a longer duration of action and often reducing how often you need to dose. The first option lists several brands that are classic examples of this approach—Plateau caps, Sequels, Extentabe, Repetabs—each structured to release the medicine gradually through coatings or matrix systems. In contrast, immediate-release tablets are made to release the drug quickly after swallowing, lozenges that dissolve in the mouth deliver the drug rapidly, and buccal patches deliver via the cheek mucosa as a different, non-oral route. So the items in the first set are the oral extended-release forms.
