NCT02848430

Brief Summary

Human safety studies were carried out to test whether hop botanical dietary supplements used by peri- and post-menopausal women are safe to use with Food and Drug Administration (FDA)-approved drugs. To test this, a hop dietary supplement (previously tested in women at the University of Illinois at Chicago without any harmful effects) was given with four selected FDA-approved drugs to determine if the hop supplement can increase or decrease how these medications are absorbed, metabolized and excreted by the human body. Preclinical studies had predicted that the hop supplement might affect the metabolism or break down of these probe drugs.

Outcome Measures

Primary Outcomes (1)

  • Area Under the Curve (AUC)

    Concentration of probe drugs from blood draws during the 14-day intervention were used to calculate area under the (extrapolated) concentration-time curve to determine any changes compared to pre-intervention.

    baseline and 14 days

Secondary Outcomes (4)

  • Apparent Clearance

    baseline and 14 days

  • Peak Concentration

    baseline and 14 days

  • Time for Peak Concentration

    baseline and 14 days

  • Drug Half-life

    baseline and 14 days

Study Arms (1)

Humulus lupulus

EXPERIMENTAL

Spent hop extract; 2 gelatin capsules (59.5 mg extract) per day for 14 days

Dietary Supplement: Humulus lupulus

Interventions

Humulus lupulusDIETARY_SUPPLEMENT

Extract of spent hops standardized to xanthohumol, isoxanthohumol, 6-prenylnaringenin, and 8-prenylnaringenin

Also known as: hops
Humulus lupulus
