A method involving the administration of a therapeutically effective amount of a leukotriene inhibitor, a pharmaceutically acceptable salt, a pharmaceutically acceptable N-oxide, a pharmaceutically active metabolite, a pharmaceutically acceptable prodrug, or pharmaceutically acceptable solvate thereof to a human for reducing a level of pro-inflammatory HDL in the human. Various examples of leukotriene inhibitors, including 3-[3-tert-butylsulfanyl-1-[4-(6-ethoxy-pyridin-3-yl)-benzyl]-5-(5-methyl-pyridin-2-ylmethoxy)-1H-indol-2-yl]-2,2-dimethyl-propionic acid, are disclosed for administration for the reduction of pro-inflammatory HDL in a human. Reduction of pro-inflammatory HDL by the leukotriene inhibitor may include conversion of at least a portion of pro-inflammatory HDL to anti-inflammatory HDL.
