Therapeutic Index, Half-life, Medication Mode of Action - Pharmacology Basics | @LevelUpRN

Get the key facts about the concept of therapeutic index and what it means if a medication has a high or low therapeutic index. Learn about the half-life and the mode of action of medications. We'll cover agonists, antagonists, and agonist-antagonists (or partial agonists).

Our Pharmacology Basics video tutorial series is taught by Cathy Parkes BSN, RN, CWCN, PHN and intended to help RN and PN nursing students study for their nursing school exams, including the ATI, HESI and NCLEX.

(Which has been extremely helpful)I just decided to step up my game a little more and ordered the med surg and pharm flash cards!!!! I can’t wait for them to get here tomorrow so I can start following along with the video!!! Thanks Maris and Cathy so far you all have helped dramatically with getting me through my semesters… I’m half way there 🎉❤

Hi Cathy, for your flash cards does it include conversion to metric system? I’m a Canadian nursing student.

[annarata]

Thank you wow you made it easier to understand

[jaymullaguru]

Helpful video! I’m a pharmacy technician and this came up at work today, you made it very easy to understand! I do have a question. Would you say that a therapeutic index may vary patient to patient since people can tolerate medications differently? Or is this more in reference to the general levels of what becomes toxic to people in general with each medication

[meaadabeed]

What about if i have a prodrug with long half life? Is that a toxic medication ??
