Interactions with Quercetin
Doxorubicin; Cisplatin

In vitro, quercetin (1 and 10 mM) potentiated the effects of adriamycin on MCF-7 ADR resistant human breast cancer cells by inhibiting growth in a dose-dependent manner (Scambia et al. 1994). Concomitant treatment with quercetin (20 mg/kg) and cisplatin (3 mg/kg) in mice implanted with human large-cell lung cancer reduced tumor growth to a greater degree than cisplatin alone (Hofmann et al. 1990). More research is needed to determine if quercetin would be a useful adjunct to chemotherapy.
