Interaction Details
Topotecan is classified as belonging to the following category: Topoisomerase I Inhibitors
Turmeric has antioxidant effects. There is some concern that this may reduce the activity of chemotherapy drugs that generate free radicals. However, research is conflicting.
In vitro research shows that curcumin, a constituent of turmeric, inhibits camptothecin-induced apoptosis of breast cancer cells by up to 71%. However, other in vitro research shows that curcumin augments the cytotoxic effects of camptothecin. Reasons for the discrepancies may relate to the dose of curcumin and the chemotherapeutic agents. Lower doses of curcumin might have antioxidant effects while higher doses might have pro-oxidant effects. More evidence is needed to determine what effect, if any, turmeric might have.

Turmeric Overview
Turmeric is a commonly used spice and a member of the ginger family (Zingiberaceae). It is native to India and other parts of South Asia and is known for its bright orange-yellow color and its warm, slightly bitter flavor.
In traditional medicine, turmeric is believed to have a number of health benefits due to its high content of antioxidants and other compounds, such as curcumin. It is thought to have anti-inflammatory and antimicrobial properties, and it is often used to treat a variety of conditions, including joint pain, digestive problems, skin disorders, and respiratory infections.
Most dietary supplements that utilize turmeric standardize their products based on a specific amount of curcumin (curcuminoids) per dose.
Additionally, turmeric supplements are often paired with black pepper extract (piperine) to improve oral absorption.
