Abstract:
Buprenorphine-naloxone (BUP-NX) is a lifesaving treatment for opioid use disorder. The increasing use of illicitly manufactured fentanyl, however, has made initiating BUP-NX more likely to precipitate withdrawal-an experience that deters treatment and causes return to use. If BUP-NX cannot be successfully started, it cannot work. We describe the case of a patient who was able to transition to a therapeutic dose of BUP-NX less than 3 hours after his last illicitly manufactured fentanyl use by choosing to self-administer intranasal naloxone. After the naloxone, the transition took 31 minutes, including 14 minutes of expected moderately severe withdrawal. He remains in care with BUP-NX and would recommend this transition approach to others.

Additional Routes of Drug Administration
Administering drugs via inhalation allows for the direct delivery of gaseous, volatile substances or droplets to different parts of the respiratory tract. One of the advantages of the inhalation route is the rapid absorption of drugs into the circulatory system, which is possible because of the large surface area of...
Drug Delivery: Miscellaneous Routes
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.

Routes of Drug Administration: Overview
Enteral administration refers to drugs absorbed through the gastrointestinal tract. They can be swallowed (perorally), placed under the tongue (sublingually), or on the inner lining of the cheeks (buccally). Perorally administered drugs take time to be absorbed and have a slower onset of action. The rectal route is another form of enteral administration, which allows for...

Enteral delivery involves administering drugs directly through swallowing, sublingual placement, or buccal application. Orally administered drugs predominantly navigate the...
