Pharmacokinetics Clinical Trial
Official title:
A Phased Clinical Trial of a Dietary Supplement Kava: Biomarker Changes and Anxiolytic Effects Phase 2: Kava Biomarker
This study will examine the utility of plasma and urinary based biomarkers for the anxiolytic properties of kava. The investigators will conduct a one week, double blind, randomized placebo controlled trial of kava, dosed at three 75 mg capsules per day, vs placebo, in adults with generalized anxiety disorder.
This study will examine the utility of plasma and urinary based biomarkers for the anxiolytic properties of kava, a natural dietary supplement. The investigators will conduct a one week, double blind, randomized placebo controlled trial of kava, dosed at three 75 mg capsules per day, vs placebo, in adults with generalized anxiety disorder. Clinical measures of anxiety, blood, and urine will be obtained. Biomarkers of interest include PRKACA, cortisol, urinary TCE, and NA5HT. Participants will be assessed pre- and post-treatment. The participants will also be followed for 12 weeks after the end of treatment to identify any potential rare adverse events, particularly liver toxicity, that appear in a delayed fashion. ;
