OATP1A2 Substrates

    OATP1A2 substrates include, but are not limited to, acebutolol, aliskiren, atenolol, docetaxel, fexofenadine, imatinib, levofloxacin, nadolol, talinolol, and sildenafil. See glossary page for a more comprehensive list.

    Summary

    OATP1A2 substrates include drugs that use OATP1A2 — an organic anion-transporting polypeptide — for transport into the cells of various organs and tissues in the body. OATP1A2 transporters are found in the intestine, liver, kidney, and blood-brain barrier, where they can facilitate the absorption of OATP1A2 substrates into the blood and brain as well as their metabolism and excretion via the liver and kidney.[1][2][3]

    Certain foods, medications, or supplements may alter OATP1A2 activity, potentially causing drug interactions by affecting the pharmacokinetics of drugs that are OATP1A2 substrates.[1]

    The table below outlines identified OATP1A2 substrates.[2][3][4][5]​​ Importantly, this list is not exhaustive.
