The 'Cooperstown 5 + 1 cocktail', [2] in addition to the four drug probes mentioned above, incorporates warfarin as well. Warfarin (actually the S-warfarin enantiomer) is a specific probe for CYP2C9. The '+ 1' refers to the vitamin K that is given together with the warfarin to prevent any anticoagulant effect.
According to research by the Kaiser Family Foundation, about 1 in 8 adults in the U.S. has taken a GLP-1 drug to treat diabetes, promote weight loss or prevent heart attacks or strokes (in those ...
Pharmacodynamics (PD) is the study of the biochemical and physiologic effects of drugs (especially pharmaceutical drugs). The effects can include those manifested within animals (including humans), microorganisms , or combinations of organisms (for example, infection ).
When two drugs affect each other, it is a drug–drug interaction (DDI). The risk of a DDI increases with the number of drugs used. [1] A large share of elderly people regularly use five or more medications or supplements, with a significant risk of side-effects from drug–drug interactions. [2] Drug interactions can be of three kinds:
There are three types of DTIs, dependent on their interaction with the thrombin molecule. Bivalent DTIs (hirudin and analogs) bind both to the active site and exosite 1, while univalent DTIs bind only to the active site. [1] The third class of inhibitors, which are gaining importance recently, is the allosteric inhibitors.
Colchicine is a medication used to prevent and treat gout, [3] [4] to treat familial Mediterranean fever [5] and Behçet's disease, [6] and to reduce the risk of myocardial infarction. [7] The American College of Rheumatology recommends colchicine, nonsteroidal anti-inflammatory drugs (NSAIDs) or steroids in the treatment of gout.
Dabigatran etexilate is rapidly absorbed, it lacks interaction with cytochrome P450 enzymes and with other food and drugs, there is no need for routine monitoring and it has a broad therapeutic index and a fixed-dose administration, which is excellent safety compared with warfarin. [4]
Germline mutations in drug targets can also influence response to medications, though this is an emerging subfield within pharmacogenomics. One well-established gene-drug interaction involving a germline mutation to a drug target is warfarin (Coumadin) and VKORC1, which codes for vitamin K epoxide reductase (VKOR).
