Interaction Details
Loperamide is classified as belonging to the following category: P-Glycoprotein Substrates
Ginger might increase the absorption and blood levels of P-glycoprotein (P-gp) substrates.
In vitro research and case reports suggest that ginger inhibits drug efflux by P-gp, potentially increasing absorption and serum levels of P-gp substrates. Two case reports from the World Health Organization (WHO) adverse drug reaction database describe increased toxicity in patients taking ginger and cancer medications that are P-gp substrates (trametinib, crizotinib). However, the causality of this interaction is unclear due to the presence of multiple interacting drugs and routes of administration.

Ginger Overview
Ginger is a spice native to Asia and part of the Zingiberaceae family. It has a pungent, spicy flavor and is often used to add flavor to dishes and drinks.
Ginger has a long history of use in traditional medicine and is believed to have anti-inflammatory, antioxidant, and other medicinal properties. It is commonly used to treat nausea, motion sickness, and other digestive issues. Ginger is also sometimes used to relieve pain and reduce inflammation.
Ginger supplements generally standardize several compounds found in the root, and are often labeled as containing a certain amount of 'ginger root extract'.
Loperamide Overview
-
Nonprescription (over-the-counter) loperamide is used to control acute diarrhea (loose stools that come on suddenly and usually lasts less than 2 weeks), including travelers' diarrhea. Prescription loperamide is also used to control acute diarrhea and also ongoing diarrhea associated with inflammatory bowel disease (IBD; condition in which the lining of all or part of the intestine is swollen, irritated, or has sores). Prescription loperamide is also used to reduce the amount of fluid in people with ileostomies (surgery to create an opening for waste to leave the body through the abdomen). Loperamide is in a class of medications called antidiarrheal agents. It works by decreasing the flow of fluids and electrolytes into the bowel and by slowing down the movement of the bowel to decrease the number of bowel movements.
