| Gene Name | OATP1B1 | ||||||||
| Uniprot ID | SO1B1_HUMAN | ||||||||
| KEGG Pathway | hsa:10599 | ||||||||
| Protein Family | Organo anion transporter (TC 2.A.60) family | ||||||||
| Protein Function |
Mediates the Na(+)-independent uptake of organic anions such as pravastatin, taurocholate, methotrexate, dehydroepiandrosterone sulfate, 17-beta-glucuronosyl estradiol, estrone sulfate, prostaglandin E2, thromboxane B2, leukotriene C3, leukotriene E4, thyroxine and triiodothyronine. Involved in the clearance of bile acids and organic anions from the liver.

| Recommended Action | |||||||||
|---|---|---|---|---|---|---|---|---|---|
| Management | Caution is advised when entrectinib is prescribed with drugs that are OATP1B1 substrates, particularly those with a narrow therapeutic range such as atorvastatin, pravastatin, rosuvastatin, repaglinide, and bosentan. Dosage adjustments as well as clinical and laboratory monitoring may be appropriate for some drugs whenever entrectinib is added to or withdrawn from therapy. | ||||||||
