2020 Jul 23;11:1796. doi: 10.3389/fmicb.2020.01796. As a large number of therapeutic reagents are substrates and/or inhibitors of OATP1B1 and OATP1B3, we should be aware of DDIs caused by the inhibition of these transporters. DDI data were collected based on a search of the University of Washington Metabolism and Transport Drug Interaction Database [Hachad et al. 2007 Aug;35(8):1308-14. doi: 10.1124/dmd.106.012930. xref
Potential drug interactions should be researched, and medication changes should only be made after consulting a health professional. 0000005106 00000 n
of the main guidance documents for details. * Recommend the use of 2 structurally unrelated CYP3A4/5 substrates for evaluation of in vitro CYP3A4/5 inhibition.Most chemical inhibitors are not specific for an individual CYP enzyme. Gemfibrozil displays DDIs with some OATP1B1 substrates, although their extent is small. The selectivity and potency of inhibitors should be verified in the same experimental conditions using probe substrates for each CYP enzyme. %PDF-1.6

Your doctor may want check how your elagolix is working or the amount of elagolix in your blood. In vitro and in vivo studies have shown that some drugs inhibit these transporters and cause clinically relevant drug-drug interactions (DDIs). Elagolix/Strong OATP1B1 Inhibitors Interactions. Index inducers listed in this table were selected based on potency of induction, safety profiles, and number of reported clinical DDI studies with different in vivo substrates (≥ 2 substrates).

ACRONYMS AND DEFINITIONS; CYP - Cytochrome P450; OATP - Organic anion transporting … DDI data were collected based on a search of the University of Washington Metabolism and Transport Drug Interaction Database [Hachad et al. Based on the gemfibrozil-induced increase in statin plasma concentration, an increased risk of statin toxicity (muscle weakness, pain, myopathy, myositis) would be … These medicines may interact and cause very harmful effects and are usually not taken together. 0000004826 00000 n
Inhibitors OATP1B1-HEK293 Ki= IC50 1 + S/Km (assuming competitive inhibition) (The compounds taken up by cells were quantified by LC-MS/MS.)

Atorvastatin AUC was significantly increased with concomitant ACE inhibitors can also interact with several other medications (including NSAIDs and lithium). The pretreatment of OATP1B1- and OATP1B3-expressing cells with 0.5-10 µM CsA, but not TCR, resulted in a reduction in their activity, even after washing out CsA from the incubation media. DDI data were collected based on a search of the University of Washington Metabolism and Transport Drug Interaction Database [Hachad et al. Moderate sensitive substrates are drug that demonstrate an increase in AUC of ≥2 to <5-fold with strong index inhibitors of a given metabolic pathway in clinical DDI studies.This table is prepared to provide examples of clinical sensitive or moderate sensitive index substrates and is not intended to be an exhaustive list. OATP1B1 is restrictedly expressed in the basolateral membrane of human hepatocytes and transports a broad range of compounds such as bile acids, conjugated steroids, thyroid hormones, peptides, and drugs including rifampicin and HMG-CoA reductase inhibitors –. 2019 Jun;20(8):571-580. doi: 10.2217/pgs-2019-0020.Mol Pharmacol. ��6���i�?��֪-�r���ԏ�L���()�P?�P�T;?ص Therapeutically important drugs such as cyclosporine, gemfibrozil, some statins, antibiotics, and antiretroviral drugs are recognized clinical inhibitors of OATP1B1. (f) Strong inhibitors … Rifampicin is also an inducer of metabolic enzymes, and although its single coadministration produces an increase in the plasma concentration of the affected drugs, multiple coadministrations may result in reductions in the plasma concentrations of OATP1B1 and CYP3A4 bisubstrates. 2019 May;95(5):490-506. doi: 10.1124/mol.118.114314. 0000004865 00000 n
J-STAGE, Japan Science and Technology Information Aggregator, Electronic Sensitive substrates of CYP3A with ≥10-fold increase in AUC by co-administration of strong index inhibitors are shown above the dashed line. Index substrates listed in this table were selected considering their sensitivity, specificity, safety profiles, and adequate number of reported clinical DDI studies with different in vivo inhibitors (≥ 3 for CYP3A or ≥ 2 for CYP1A2, 2C8, 2C9, 2C19, and 2D6). (2010), Hum Genomics, 5(1):61].Note: Strong, moderate, and weak inhibitors are drugs that increase the AUC of sensitive index substrates of a given metabolic pathway ≥5-fold, ≥2 to <5-fold, and ≥1.25 to <2-fold, respectively.
