Top 100 Prescribed Drugs with CPIC Guidelines

Pharmacogenetics has important consequences for some of the most commonly prescribed medications. Depending on the source and structure of the list, the 100 most commonly prescribed drugs include between 3 (RxList from the Medscape report of August 2014 http://www.rxlist.com/script/main/hp.asp ) and 16 (Pharmacy student study guide http://www.pharmacy-tech-study.com/memorize-the-top-200-drugs.html) drugs with CPIC recommendations.  CPIC guidelines offer recommendations for changes to drug choice or drug dose based on patient genotype, with important implications for efficacy and toxicity, and can be found at cpicpgx.org.  In the RxList, the drugs with CPIC guidelines are rosuvastatin, simvastatin, and atorvastatin. In the pharmacy study list, the drugs with CPIC guidelines are citalopram, escitalopram, warfarin, clopidogrel, amitriptyline, paroxetine, sertraline, oxycodon, codeine, allopurinol, and the 5 statins simvastatin, rosuvastatin, pravastatin, atorvastatin, and lovastatin. In addition, the illustrated pharmacokinetic and pharmacodynamics pathways developed and freely available on the PharmGKB website contain 37 of the drugs found on the pharmacy study list.
