Description
Sources: https://www.ncbi.nlm.nih.gov/pubmed/9618424
Curator's Comment: Description was created based on several sources, including https://www.addictioncenter.com/painkillers/fentanyl/ | https://www.ncbi.nlm.nih.gov/pubmed/24635521

Fentanyl is a potent agonist of mu opioid receptor. It is used to relieve severe pain, such as after surgery or during cancer treatment, and breakthrough pain (flare-ups of intense pain despite round-the-clock narcotic treatment). Fentanyl is an extremely powerful analgesic, 50–100-times more potent than morphine. Fentanyl harbors massive risk for addiction and abuse regardless of its prescription form. Fentanyl abuse is especially dangerous to those without a tolerance to opioids. The substance’s already elevated risk of overdose is multiplied when someone without a tolerance abuses it.

Patients considered opioid-tolerant are those who are taking at least 60 mg of morphine daily, or at least 30 mg of oral oxycodone daily, or at least 8 mg of oral hydromorphone daily, or an equianalgesic dose of another opioid for a week or longer. Fentanyl transdermal system contains fentanyl, a full opioid agonist. Fentanyl transdermal system is indicated for the management of persistent, moderate to severe chronic pain in opioid‑tolerant patients 2 years of age and older when a continuous, around-the-clock opioid analgesic is needed for an extended period of time. (1) Fentanyl transdermal system is NOT intended for use as an as-needed analgesic. (1) Launch Date 1990

In Vivo Use Guide

Dosage should be individualized. Some of the factors to be considered in determining the dose are age, body weight, physical status, underlying pathological condition, use of other drugs, type of anesthesia to be used and the surgical procedure involved. Dosage should be reduced in elderly or debilitated patients (see PRECAUTIONS). Vital signs should be monitored routinely. I. Premedication — Premedication (to be appropriately modified in the elderly, debilitated and those who have received other depressant drugs) — 50 to 100 mcg (0.05 to 0.1 mg) (1 to 2 mL) may be administered intramuscularly 30 to 60 minutes prior to surgery. II. Adjunct to General Anesthesia — See Dosage Range Chart III. Adjunct to Regional Anesthesia - 50 to 100 mcg (0.05 to 0.1 mg) (1 to 2 mL) may be administered intramuscularly or slowly intravenously, over one to two minutes, when additional analgesia is required. IV. Postoperatively (recovery room) - 50 to 100 mcg (0.05 to 0.1 mg) (1 to 2 mL) may be administered intramuscularly for the control of pain, tachypnea and emergence delirium. The dose may be repeated in one to two hours as needed
