Understanding the full utility and side effects of fentanyl and other phenylpiperidine formulations is crucial to find the best and effective medication for perioperative and chronic pain management.

Acute pain usually starts suddenly and is of sharp quality. Chronic pain is ongoing and lasts longer than 6 months, often continue after an injury has healed. Phenylpiperidines derivatives can be used in getting relief from acute and chronic Pain. It has significant function in many aspects of medicine like anesthesia and pain medicine. These agents are chemical class of drugs with a phenyl moiety directly attached to piperidine.

The aim of this review is to focus on phenylpiperidine derivatives and their use in current anesthesia and perioperative medicine practice. Second generation synthetic phenylpiperidine which is a series of opioid such as meperidine, fentanyl, was synthesized and introduced as fentanyl citrate into clinical anesthesia practice in 1968. Fentanyl- mediated or modulated responses enhance the pain threshold, and provides both analgesic and sedative effects. It acts as an agonist at mu-opioid receptor, at the dorsal horn inhibiting ascending pain pathways in the rostral ventral medulla. As fentanyl is metabolized mainly via CYP3A4, its possibility that adverse effects may occur with concomitant use of any drug which affects CYP3A4 activity. Stopping the use of CYP3A4 inducers can also result in an increase in fentanyl plasma concentration. The routes to administer Fentanyl-based formulations could be intravenous, intramuscular, transdermal, transmucosal, and neuraxial routes. Remifentanil which 2 times potent than Fenatanyl, can be used as ultra-short-acting analgesic. The newer formulations of sufentanil, which is an analog and 5 to 10 times potent than Fentanyl, currently being evaluated for acute pain management. We examine the routes of administration and clinical considerations, including the role of opioids such as fentanyl as a natural killer cell suppressive agent. Fentanyl and other opioids have been shown to potentiate propagation of infection and cancer.

In recent years, fentanyl and other phenylpiperidine formulations have been developed and successfully marketed for chronic pain management. Due to complex physiological responses and potential drug-drug interactions of opioids, the clinician should recognize all the aspects of this drug class and consider all available options in appropriate clinical settings.
