Which medication used to treat narcotic dependence is available in a sublingual form?

Subutex is a medication specifically designed for the treatment of narcotic dependence and is available in a sublingual form, which means it is placed under the tongue to dissolve. This method of administration allows for rapid absorption into the bloodstream, making it effective for managing opioid withdrawal symptoms.

Subutex contains buprenorphine as its active ingredient, which helps reduce cravings and withdrawal symptoms in individuals trying to overcome addiction to stronger opioids. The sublingual route is advantageous because it bypasses the gastrointestinal tract, ensuring that the medication is absorbed efficiently.

In contrast, although Suboxone also contains buprenorphine, it includes an opioid antagonist named naloxone to prevent misuse. Theoryx is not a recognized medication for narcotic dependence, and Buprenex, while it also contains buprenorphine, is typically administered via intramuscular or intravenous routes rather than sublingually. This distinction makes Subutex the best answer for the question regarding sublingual availability.
