Monoamine Oxidase Inhibitors (MAOIs)

Hi, I'm Cathy with Level Up RN.  In this video we are going to be   talking about MAOIs or monoamine oxidase  inhibitors. And at the end of the video,   I'm going to give you guys a little quiz to test  your knowledge of some of the key points we'll be   covering. So definitely stay tuned for that.  And if you have our Level Up RN, psychiatric   mental health nursing flashcards definitely pull  out your flashcards so you can follow along with   me. And pay close attention to the bold red text  on this flashcard because MAOIs are highly tested   on in nursing school and those bold red items  are likely to show up on a nursing school exam.   Anyways include medications such as  phenelzine, tranylcypromine, isocarboxazid,   as well as selegiline. And these medications work  by inhibiting the enzyme monoamine oxidase which   causes an increase in neurotransmitters such  as norepinephrine, serotonin, and dopamine. Key   side effects include anxiety, agitation,  orthostatic hypotension, and the risk for   a hypertensive crisis. That is definitely the  most important side effect to remember when it   comes to MAOIs. Our cool chicken hint to help  you remember this is please take it seriously.   Phenelzine, tranylcypromine, isocarboxazid,  and selegiline can cause a hypertensive crisis.   It's also super important to know that if  your patient consumes foods that are rich   in tyramines when they're taking an MAOI,  this can result in a hypertensive crisis.  So foods that are rich in tyramines include  avocados, bananas, aged cheese, pepperoni,   and salami, red wine, and chocolate. So a lot of  the finer things in life. So our little rhyme to   help you remember this fact is with phenelzine  you can't enjoy life's finer things because   they contain tyramines. In addition to teaching  your patient to avoid foods rich in tyramines,   you should also teach your patient that MAOIs  interact with many other medications including   over-the-counter cold medications. And this  interaction can lead to a hypertensive crisis.   If your patient wants to switch from an MAOI to  another antidepressant, a two-week washout period   is necessary between the time they discontinued  the MAOI and before they start their new   medication. All right, it's time for a quiz, and  I've got three questions for you. Question number   one, consuming foods rich in blank can cause a  hypertensive crisis in a patient taking an MAOI.   The answer is tyramines. Question number  two, this is a multiple-choice question.   Which of the following snacks would be appropriate  for someone taking fennel phenelzine? A, Cheddar   cheese and crackers. B, chips and guacamole. C,  cereal with milk. Or D, a pepperoni pizza slice.   The answer is C, cereal with milk. All the other  options are high in tyramines. Question number   three, a patient taking an MAOI can safely  use a decongestant for a cold. True or false.   The answer is false. So MAOIs interact  with many other medications including   many cold or cough medications. So  the patient will need to check what   their provider first before taking  any other medication. All right,   that is it for this video. I hope you found it  helpful. Take care and good luck with studying.
