What is the primary use of the oral Fentanyl lozenge?

The primary use of the oral Fentanyl lozenge is to provide analgesia, which means it is intended to relieve pain. Fentanyl is a potent synthetic opioid that acts on the brain's opioid receptors to decrease the perception of pain and enhance pain tolerance. The lozenge form allows for rapid absorption of the medication through the mucous membranes in the mouth, providing quick relief for patients experiencing acute pain, particularly in situations like combat or emergency medical scenarios.

The other options involve uses of medication that are outside the intended purpose of Fentanyl lozenges. Inducing anesthesia typically involves different methods and medications designed for use in surgical settings, while managing severe inflammation is more appropriately treated with anti-inflammatory drugs rather than opioids. Lastly, treating bacterial infections falls under the use of antibiotics, not analgesics like Fentanyl. Therefore, the focus of the lozenge is solely on pain management, making analgesia its primary function.
