Description

It is not known whether daily oral dosing will produce a tolerable prolonged exposure to therapeutic levels of hypericin. Pharmacokinetic modeling studies have demonstrated that daily oral dosing should produce a trough level in a desired range without excessive peak levels. Cohorts of six patients each receive escalating doses of oral hypericin daily. Blood is sampled for peak and trough levels the second week of therapy. A computer modeling algorithm will use these levels to determine the appropriate dose needed for each patient to achieve the desired trough level. When three of six pati...
