Infobord.png More information
  • Hypericum induces enzymes of the CYP P-450 type and P-gp type.
  • Hypericum might have MAO-inhibiting and/or COMT-inhibiting properties.
  • Many studies reported that hypericin is the main source of pharmacological effects of hypericum. However the IC50 of hypericin to inhibit MAO A and MAO B is 100- to 1000-fold higher than accessible Cmax values of hypericin after oral administration of hypericum.[3]
  • No severe interactions are known.
  1. Switches are based on literature references on this page and expert opinions of the authors. The authors have used pharmacokinetic and receptor affinity properties to determine the switch schedules
