SSRIs and other antidepressant medications constitute one of the most commonly prescribed drug classes that pharmacists will see in the community setting. When taken alone, any one of these medications can be a good treatment option for patients experiencing depression; however, these drugs can cause a patient who is taking multiple drugs to experience significant interactions with his/her other medications. For this reason, it is crucial to know how the effects of other medications can be altered through this therapy. This study analyzed the effects of two SSRIs (citalopram and fluvoxamine) on the blood thinning medication clopidogrel. These medications all work on the same CYP enzyme (CYP2C19) and have opposing effects. Researches tested these medications on healthy individuals and found that fluvoxamine was the only drug that caused significant inhibition of clopidogrel action.
I think this is important to note because these medications are commonly utilized by patients and thus there is a high likelihood that they may be taken together. As pharmacists, we should be able to provide adequate care in response to possible drug-drug interactions. To do this, we have to be able to recognize when there could potentially be a problem in medication therapy. By taking the proper precautions when these situations arise, pharmacists will be more likely to help patients avoid adverse medical events associated to drug therapy methods.
