Interaction Details
Simvastatin, Sitagliptin is classified as belonging to the following category: Organic Anion-Transporting Polypeptide Substrates (Oatp)
Consuming sweet orange juice can decrease oral absorption of OATP substrates. Separate administration by at least 4 hours.
Clinical research shows that consuming sweet orange juice inhibits OATP, which reduces bioavailability of oral drugs that are substrates of OATP. For example, sweet orange juice decreases bioavailability of fexofenadine, a substrate of OATP, by about 72% and of celiprolol, another OATP substrate, by up to 90%. Since sweet orange juice seems to affect OATP for a short time, recommend separating drug administration and consumption of sweet orange juice by at least 4 hours.

Sweet Orange Overview
Sweet orange, also known as Citrus sinensis, is a type of citrus fruit native to Southeast Asia. It is a good source of vitamin C and other nutrients, including folate, potassium, and dietary fiber. It is also a good source of antioxidants, which are substances that help to protect the body's cells from damage caused by free radicals.
Sweet orange is used in traditional medicine as both aromatherapy and herbal remedies. The essential oil is generally extracted from the sweet orange peel and is used for its purported relaxant properties. As a dietary supplement, it is most commonly used to treat digestive problems and to help reduce the severity of colds and other respiratory infections.
