Overview of Gastrointestinal Medications

Hi, I'm Cathy, with Level Up RN. In this  video, I'm going to start in on our coverage   of gastrointestinal medications. So if you have  our pharmacology second edition flashcards,   definitely pull those out. We are in the green  section so you can follow along. Specifically,   in this video, I will be covering anti-ulcer  agents. And at the end of the video, I'm going to   provide you guys a quiz to test your understanding  of some of the key facts I'll be covering in this   video. So definitely stay tuned for that. Histamine-2 receptor antagonist is the first   drug class I'm going to cover. Medications that  fall within this class include ranitidine and   famotidine. These medications can be used to treat  gastroesophageal reflux disease, so GERD, as well   as duodenal and gastric ulcers, and also a rare  disorder called Zollinger-Ellison syndrome, which   causes excess gastric acid production. So the mode  of action of this drug class is that it blocks H2   receptors in the stomach, and this reduces gastric  acid secretion. Side effects are minimal. They can   include a headache as well as GI upset. The way I  remember these medications and what they're for,   if you look at the drug name-- so ranitidine and  famotidine, they end in that dine, spelled D-I-N-E   like dine. So I remember that if you take your  ranitidine, or dine, it will help your stomach   feel better when you dine. So when you eat.  So hopefully that's helpful for you as well.  Next, we have our proton pump inhibitors or PPIs.  Medications that fall within this class include   omeprazole, as well as pantoprazole. And these  medications are used to treat the same conditions   as our histamine-2 receptor antagonists. So we  can use PPIs to treat GERD, to treat ulcers,   as well as Zollinger-Ellison syndrome. So  PPIs inhibit an enzyme that is required   for gastric acid secretion. So we have decreased  gastric acid secretion with PPIs. Side effects   can include GI upset, C. diff, and with long term  use, we can end up with bone fractures. Nursing   care includes closely monitoring the patient for  diarrhea, cramping, and bloody stools. And then   my way of remembering these drugs, if you look at  how they're spelled, they both have that P-R-A-Z   in the middle, so praise. It's not pronounced  that way. It's pronounced omeprazole, but it kind   of looks like oma-praise-all. So my son's little  tip for how to remember this is, I want to praise   you for taking your anti-ulcer medications. So if  you like that tip, be sure to leave him a comment   here because he was just accusing me of not giving  him credit for his tricks that he gives me. So   I definitely want to give him credit,  and I have given him credit in the past,   so leave him a comment. Thank you so much. Sucralfate is the next medication I want   to cover, which is a mucosal protectant that  is used in the treatment of duodenal ulcers.   So sucralfate reacts with the stomach's acid to  form a thick paste which adheres to the ulcers.   Key side effect with sucralfate is constipation.  You want to administer this medication one hour   before meals and at bedtime, so four times a  day. Also, you want to encourage your patient to   increase their intake of fiber and fluids  because of that side effect of constipation.   So my way of remembering this medication and  what it's for, and the cool chicken hint here   on the card, is sucralfate gets sucked down into  ulcers. So S-U-C, sucralfate becomes sucked down   into ulcers, which is pretty much what it  does. So hopefully that's helpful for you.  Next, we have antacids, including aluminum  hydroxide. Antacids are used to treat peptic   ulcer disease as well as GERD. They  work by neutralizing the stomach acid,   and a key side effect of antacids is constipation.  In terms of administration, we're going to give   antacids after meals and at bedtime. So A for  antacids and A for after meals. Another important   thing to know about administration is that we  never want to give antacids at the same time as   other medications, so we want to give antacids one  to two hours before or after other medications.   So antacids are a little fussy when it comes to  administration, because we need to give it after   each meal and at bedtime, and we need to make  sure we're not giving it with other medications.  The last medication I want to cover in this  video is misoprostol, which is a prostaglandiin   that is used to prevent gastric ulcers  in patients taking NSAIDs. It also   induces labor by ripening the cervix. So  the mode of action of misoprostol is that it   decreases stomach acid secretion, and it  increases the production of protective mucus   in the stomach as well as bicarbonate.  And it also causes uterine contractions   when used for labor induction. So side effects  include dysmenorrhea as well as GI upset.   This medication does carry a black box  warning because it can cause a miscarriage,   premature birth and birth defects. So any time we  are administering misoprostol for ulcer prevention   in a female of childbearing age, we always want  to run a pregnancy test first because it can cause   a miscarriage. So my cool chicken hint here  on this card, if you look at misoprostol,   it kind of looks like me-so-prostol. So  when you're pregnant, miso soup is okay;   misoprostol is not. And again, it's pronounced  misoprostol, but it looks like that miso.   So I hope that hint was helpful for you. Okay, time for quiz. I have three   questions for you. First question. When  should your patient take sucralfate?   The answer is one hour before meals and  at bedtime. Question number two. Aluminum   hydroxide should be administered at the same  time as other medications. True or false?   The answer is false. So aluminum hydroxide  is an antacid, and antacids should never be   given at the same time as other medications.  You need to give them one to two hours before   or after other medications. Question number three.   What nursing assessment should be done  prior to administration of misoprostol?   The answer is, you should run a pregnancy test for  any woman of childbearing age who is prescribed   misoprostol for ulcer prevention because  this medication can cause a miscarriage.   Okay. I hope these quiz questions have  been helpful. Hope the video was helpful.   And hopefully my little silly ways of remembering  these medications were also helpful. If you have   other mnemonics or suggestions for how to  remember these meds, definitely leave a   comment so that everyone can benefit from your  ideas as well.
