As an instructor with those 200 drugs I see them all as seven pictures. I don't need two hundred note cards I can just do it from memory, and that's where I want you to get to so we'll start with chapter one gastrointestinal. And we'll talk about thirteen medications and while I talk about the thirteen medications I'll also talk about grouping them and grouping them When you're first learning these top 200 drugs when you group them Students are good at grouping them as okay these are analgesics and these are Maybe for some kind of stomach upset and then these are for pain But this is another level where we're connecting all 200 drugs in one order so let's start with two drugs that you're probably very familiar with two antacids And then from the antacids we're going to go to the H2 blockers And these are better known as histamine Two Receptor Antagonists So there is a histamine 1, that's the anti-histamine you think of when you think of Claritin and things like that The receptor just means that the drug is going to affect the receptor and an antagonist means it blocks it. So histamine two must release gastric acid if we're using a drug to block it. And then proton pump inhibitors So within each of these categories, I'm going to alphabetize them Because it makes it easier to remember Although magnesium is above calcium on the periodic table. We're going to put calcium carbonate first So calcium carbonate is Tums But I also want you to know that it's something called Children's Pepto This is important because regular Pepto has a salicylate component. That's a lot like aspirin and that can be very dangerous in children, especially if a child has Some kind of Chickenpox or fever and things like that and get Reye's syndrome spelled Reye apostrophe "s" There's Magnesium hydroxide And that's Milk of Magnesia So these antacids they work very quickly And because they work quickly what we're going to do for the way that we're going to remember them is These work in a couple minutes. Maybe five minutes These work in about 30 minutes the H2 blockers, and then these work in about a day But antacids are probably the first thing you'll reach for because they work so quickly then if it persists you might go to an H2 blocker and We have two that we're going to use, famotidine ranitidine I'm not going to put the brand names yet because I want you to notice that there's a -tidine ending t-i-d-i-n-e The first thing I want you to know is that the -ine is not the ending a lot of the videos on YouTube show that as the ending just because 20% of all drugs end in -ine So you don't want to classify it by that. The -tidine has been set by a couple of organizations [like] the World Health Organization, the United States Adopted Names Council, and they're the ones that make this into a group so that it's a -tidine makes it a cimetidine-like H2 blocker and cimetidine was the first H2 blocker that came out So let's put the brand names in there: Pepcid Which combines peptic and acid Zantac You can kind of see the word antagonist in there for acid, and then two proton pump inhibitors And we're going to see similar ending or that they're going to have similar endings And then I'm going to introduce something new as well there so esomeprazole There's (brand) Nexium (generic) omeprazole (brand) Prilosec, okay -prazole ending is what lets us know it's a proton pump inhibitor, but you'll notice we have omeprazole and omeprazole What's the es- what's this doing? If you look in and Wiki is a good place to look because it has good pictures of molecules. This omeprazole is actually an R- plus S- where this omeprazole is just an S- so what does that mean? There's a left-handed or there's a right-handed rectus and left-handed sinister omeprazole, so it's a mixed there's two sides to the molecule and only the S- does anything so Prilosec came first "protons low secretion" is how you remember the brand name and Then esomeprazole or Nexium came next and you can remember that from Nexium But just notice that these have the same root, okay? but they still have this ending -prazole Be careful some of those YouTube videos call it -azole and Those are maybe people that haven't had organic chemistry an -azole is just an organic chemistry compound But -prazole is an actual stem by the United States Adopted Names Council, so let's look at our first six drugs in order we start with antacids Calcium carbonate and Magnesium hydroxide alphabetized although on the periodic table. I know magnesium comes first It's 12 calcium carbonate is 20 H2 Blockers alphabetize them: famotidine, ranitidine, notice the -tidine stem the -tidine and then the proton pump inhibitors esomeprazole, omeprazole Although omeprazole came first esomeprazole should be alphabetized before omeprazole, and this es- means that it's the S- isomer and That's supposed to work a little bit better Alright, let's move on to the next group. So after you have a stomachache sometimes you get diarrhea So let's look at some drugs for that Okay, so the we're going to do again two anti diarrheals And then what we want to do is we want to do the opposite so we'll do two laxatives and so the anti-diarrheals we'll start with and again alphabetical order: bismuth subsalicylate Pepto-bismol, okay and loperamide That's Imodium So the -sal- is the stem s-a-l and the way to remember this is bismuth subsalicylate. It's this big pink bottle many people know about it, but just recognize that bismuth subsalicylate Pepto-bismol is different than Pepto Children's Loperamide you see lo- for slow and -per- for peristalsis so slowing peristalsis or Making Imodium, Imodium looks a little like immobilized, so we're slowing things down If a patient has diarrhea now again, we don't use those drugs if the patient has some kind of infection We'll treat that with antibiotics, but let's go to the opposite. Let's go to the laxatives on what we can use Let's start with Docusate And you can see as docusate or docusate sodium That's Colace and then we'll also see polyethylene glycol That's MiraLax. Polyethylene Glycol, sort of has a stem. The p, the e, and the g tells you that it's pegylated but docusate sodium I know I have it under laxative It's really a stool softener, but think of the word docusate and penetrate as rhyming and then polyethylene glycol this is the miracle laxative is a way you can remember it, but also Colace allowing the colon to race now giving a laxative So we've gone from the stomach now to the intestines and These have all been over-the-counter, so let me put that in front of these OTC OTC and What we want to do is we, again, want to have a logical order of things so we're going to go from OTC to Rx and The Rx drugs, we'll look at are the antiemetics Antiemetics are those drugs that help with nausea and vomiting and a very important drug that came out, It's called ondansetron Ondansetron is [brand] Zofran and It has the -setron stem you'll see another couple of medications that have the -setron stem and then We use promethazine Which is Phenergan I'm also going to put something here next to the Zofran and [it's] ODT Zofran comes as an orally disintegrating tablet because Sometimes if somebody's vomiting even just taking a little bit of water would make them vomit again So the orally disintegrating tablet allows it to just dissolve The Phenergan comes as a rectal suppository, again because the patient is vomiting, they would lose the medication if they took it as a pill. It's another form Okay, so what we've done is we've gone from the stomach down to the intestines back up to the mouth if you want to put it that way, and then we're going to go back to the intestines. There's two ways that I look at it You're already there if you're thinking of the rectal suppository promethazine ulcerative colitis and so the last one we're going to do is something for ulcerative colitis And this drug is infliximab And that's Remicade "Remission Aide" so sometimes ulcerative colitis can go into remission, and that's how you remember it. This says one of the most complex stems It's a monoclonal antibody so m-a-b for mab, monoclonal antibody, the -li- and -xi- both have meaning and I go over into detail in the book But just since we're just reviewing but the -liximab is actually the stem And the monoclonal antibody doesn't tell you anything really about what it does, it just tells you it's a monoclonal antibody The -li- and the -xi- are much more useful because we're going to see in later chapters things like Xolair And etanercept and other biologics that have these complicated stems But again if you're going to try to memorize it you really want to memorize the GI drugs where they're working. So we went to the intestines Down to the rectum with this promethazine and then ulcerative colitis we would give some kind of injection of Remicade, but that's The ulcers and the inflammation are there in the intestines
