Interaction Details
Netupitant, Palonosetron (Oral) is classified as belonging to the following category: Cytochrome P450 3A4 (Cyp3A4) Substrates
Laboratory research suggests that lentinan might increase the activity of cytochrome P450 3A4 (CYP3A4). So far, this interaction has not been reported in humans. However, watch for a decrease in the levels of drugs metabolized by CYP3A4 in patients taking lentinan.
Some drugs metabolized by CYP3A4 include lovastatin (Mevacor), ketoconazole (Nizoral), itraconazole (Sporanox), fexofenadine (Allegra), triazolam (Halcion), and numerous others.

Lentinan Overview
Lentinan is a type of polysaccharide that is extracted from the edible mushroom Lentinula edodes, also known as shiitake. The main part of lentinan is Beta-1,3-glucan and supplements are often marketed simply under that name. Lentinan has been used for centuries in traditional medicine for its purported immune-boosting and anti-inflammatory properties. Some studies have suggested that lentinan may have anti-tumor effects and may help to boost the immune system, but more research is needed to confirm these effects and to determine the appropriate dosage and duration of use.
