Methods of delivering or administering stabilized formulations or compositions having predetermined ratios, or range of ratios, of constituent epimers to an individual or a mammal for treatment of central nervous system diseases, pathologies, and drug abuse and compositions for stabilizing the compositions. In one embodiment, the predetermined ratios of constituent epimers, or range of ratios, are predetermined ratios of 2-[6S-(2S-hydroxy-2-phenyl-ethyl)-1-methyl-piperidin-2R-yl]-1-phenyl-ethanone (2R-lobeline) and its epimer, 2-[6S-(2S-hydroxy-2-phenyl-ethyl)-1-methyl-piperidin-2S-yl]-1-phenyl-ethanone (2S-lobeline). In embodiments, the stabilized formulations or compositions of 2R- and 2S-lobeline are provided in the ranges between 1 part 2R-lobeline to 10000 parts 2S-lobeline to 10000 parts 2R-lobeline to 1 part 2S-lobeline, or in the range of a 1 to 1 mixture of 2R- and 2S-lobeline, so that the predetermined epimeric ratio of 2R- and 2S-lobeline is delivered or administered to the blood, plasma or tissues of a patient so treated. |
