Sintesi
St John's wort is a potent inducer of intestinal P-glycoprotein and can markedly lower plasma concentrations of both ledipasvir and sofosbuvir. Reduced exposure may lead to loss of antiviral activity, failure to achieve sustained virologic response and possible resistance.
Cosa significa questa interazione in parole semplici
Ledipasvir-sofosbuvir and St john's wort are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.
Perché avviene
Induction of intestinal P-glycoprotein (and other inducible pathways) by St John's wort reduces absorption and plasma exposure of ledipasvir and sofosbuvir.
Cosa fare
Do not combine; stop St John's wort before starting the hepatitis C regimen and choose an alternative if a herbal antidepressant is desired. Counsel patients to avoid herbal products during treatment.
