SLCO2B1 can transport drugs such as the leukotriene receptor antagonist montelukast used for asthma, the antirheumatic, immunosuppressive sulfasalazine and a number of drugs acting on the cardiovascular system such as aliskiren, antihypertensive drugs of the sartan group (telmisartan) and a number of cholesterol lowering agents (rosuvastatin, atorvastatin, pravastatin) (Supplementary Table S2). This evidence concerns the gene SLCO2B1 and asthma.
