Alfentanil is a tetrazole derivative of fentanyl. Many of the pharmacologic effects of alfentanil are similar to those of fentanyl and sufentanil, but of quicker onset than those of fentanyl and of shorter duration than those of fentanyl and sufentanil. Alfentanil may cause less intense respiratory depression than equianalgesic doses of fentanyl. ⋯ Clinical trials indicate alfentanil can be used effectively as an analgesic, an analgesic supplement to anesthesia, an anesthetic induction agent, and as the major component of a general anesthetic. Its short duration of effect makes it attractive as an analgesic supplement for short ambulatory surgical procedures. Alfentanil is recommended for addition to drug formularies, but its use should be restricted to anesthesia personnel.
