Alfentanil Intravenous and Humatrope

In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.

Somatropin may reduce the blood levels and effects of alfentanil. If you are currently being treated or have recently been treated with somatropin, you may require a higher dosage to achieve adequate response to alfentanil. Talk to your doctor if you have any questions or concerns. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

MONITOR: Coadministration with inducers of CYP450 3A4 may decrease the plasma concentrations of alfentanil, which appears to be extensively metabolized by the isoenzyme. Clinical data are limited, however. In nine healthy male volunteers, intravenous administration of a single 20 mcg/kg dose of alfentanil with the potent CYP450 3A4 inducer rifampin increased alfentanil clearance by nearly 3-fold and decreased elimination half-life by 40% compared to controls. Another study also reported substantially increased clearance rates of alfentanil in seven patients receiving long-term therapy with inducer drugs compared to six patients not receiving those drugs (mean clearance 6.94 mL/min/kg vs. 3.47 mL/min/kg; half-life 50.6 hrs vs. 90.7 hrs).

MANAGEMENT: Patients who are currently receiving or have recently received drugs that induce CYP450 3A4 should be monitored for potentially decreased response to alfentanil, and the dosage adjusted as necessary.
