The CYP3A4 isozyme is responsible for the metabolism of a large number of endogenous compounds as well as a wide range of drugs (50). Fentanyl, alfentanil, and sufentanil are substrates for CYP3A4, and therefore drugs that inhibit this enzyme, such as erythromycin, HIV protease inhibitors, or cimetidine.

A 71-year-old woman received a standard bowel preparation consisting of oral erythromycin and neomycin (a total of 3 g). Surgery was postponed for one day and she received a second similar bowel preparation pre-operatively. Anaesthesia was induced with sufentanil and etomidate and maintained with isoflurane and sufentanil. Rocuronium (total dose of 60 mg over 2 hours) was used to facilitate tracheal intubation and maintain muscle relaxation. Despite clinical appearance of a reversal of the neuromuscular blockade by neostigmine 3.5 mg and glycopyrrolate 400 micrograms, the patient complained of dyspnoea and required reintubation twice. The effects of additional doses of neostigmine were inconsistent and the use edrophonium 50 mg or calcium chloride 500 mg intravenously did not result in an improvement. ... 

In contrast, in 6 healthy subjeets erythromycin 500 mg twice daily for 7 days did not to affect the pharmaeokinetics of intravenous sufentanil 3 micrograms/kg in the 9 hours following administration. Two of the subjects were the same as those who had shown an alfentanil/erythromy-cin interaction cited above.
