 Welcome to nursing school explain in this video on the therapeutic window that has to do also with a medication steady-state in its half-life as well as the peak and trough. So please also check out the other videos so that you know how these terms are tying together. So for the therapeutic window, we have to look at the medication dose as well as it affects the body over time and at a certain low dose a medication might have or there might be too little of the medication in the patient's body that it is not effective. It is not achieving the desired effect and when we give too much of the medication, it can become toxic and then have undesirable effects and so in between we have the therapeutic window, which is a pretty large reference range where we know if the medication from a certain dose to another certain dose is administered on the patient's level that they have flowing of this medication throughout their body, it is achieving the therapeutic effects that the medication has and that's also why we have different drug dosages for patients of different ages and we adjust the therapeutic window or we adjust the medication dosage according to the patient's age and kidney function sometimes. So I hope this has explained the term of the therapeutic window. Please also check out these other medication-related terms in the pharmacology playlist and I'll see you soon right back here on Nursing School Explained. Thanks for watching.
