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.

      Mechanism Description
  • Decreased clearance of Pravastatin due to the transporter inhibition by Cobicistat 

Recommended Action
      Management Caution is advised when statins are prescribed with cobicistat-containing regimens. The lowest starting dosage of the statin is recommended, then titrated as needed based on clinical response and tolerance. Some statins such as lovastatin and simvastatin are contraindicated for use with cobicistat. All patients receiving statin therapy should be advised to promptly report any unexplained muscle pain, tenderness or weakness, particularly if accompanied by fever, malaise and/or dark colored urine. Therapy should be discontinued if creatine kinase is markedly elevated in the absence of strenuous exercise or if myopathy is otherwise suspected or diagnosed.
