Different stages of the way pharmaceutical substances must take in the body like uptake, metabolism, distribution, actions on target molecules and elimination are affected by genetic variations. \u00a0Metformin, the mostly used antidiabetic drug worldwide, is not metabolized in the body, so its efficacy and the occurrence of side effects is mostly regulated by uptake and elimination via transport proteins. Genetic variations decreasing the number of transport proteins lead to a lower (or no) response to Metformin and increase the odds to suffer from side effects. In contrast to Metformin, most pharmaceutical substances are metabolized in the body and so either activated or degraded. The most prevalent drug-metabolizing enzymes belong to the Cytochrome P450 family. Genetic variations activating, decreasing their activity, or deactivating its members are largely responsible for drug metabolism and response of up to 90% of available drugs. Genetic variations also determine the strength and type of effect pharmaceutical substances have if they occur in the substances target molecules. Mutations in the adenosine receptor determine if one feels awake, motivated with increased energy, or becomes a nervous wreck, suffers from tachycardia and counting sheep all night after consuming coffee. This not only influences our daily life but is important for persons on caffeine containing medications or athletes, using caffeine to enhance their performance. Even mutations in genes in microorganisms colonizing our body might have an impact, if these microorganisms \u2013 for example in the gut \u2013 create substances, which act therapeutically in our body. This determines if isoflavone rich medications have an effect in mellowing postmenopausal symptoms.<\/p>\n<p>We investigate mutations in organic cation transporters and their effect on Metformin efficacy, to predict if additional medications or an adjustment of dose are needed to treat diabetes. Furthermore, we are interested in their effects on side effect prevalence which drastically diminishes compliance.<\/p>\n<p>We investigate mutations in caffeine target genes and metabolizing enzymes to optimize dose recommendations for performance enhancement in athletes.<\/p>\n<\/div><\/section>\n<section class=\"av_textblock_section \"  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock  '   itemprop=\"text\" ><h5 style=\"text-align: center;\">The Author<\/h5>\n<\/div><\/section>\n<div class=\"flex_column av_one_fourth  flex_column_div av-zero-column-padding first  avia-builder-el-2  el_after_av_textblock  el_before_av_one_fourth  column-top-margin\" style='border-radius:0px; '><div  class='avia-image-container  av-styling-    avia-builder-el-3  avia-builder-el-no-sibling  avia-align-center '  itemprop=\"image\" itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/ImageObject\"  ><div class='avia-image-container-inner'><div class='avia-image-overlay-wrap'><img class='avia_image' src='https:\/\/services.cbmed.at\/html\/old\/wp-content\/uploads\/2021\/10\/Picture-1-258x300.jpg' alt='Natascha Schweighofer' title='Natascha Schweighofer' height=\"300\" width=\"258\"  itemprop=\"thumbnailUrl\"  \/><\/div><\/div><\/div><\/div><div class=\"flex_column av_one_fourth  flex_column_div av-zero-column-padding   avia-builder-el-4  el_after_av_one_fourth  el_before_av_one_fourth  column-top-margin\" style='border-radius:0px; '><section class=\"av_textblock_section \"  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock  '   itemprop=\"text\" ><p>Natascha Schweighofer, Mag.
