Antiglaucoma Agents – Pharmacology – Nervous System |Level Up RN

  • by

In this video, Cathy covers antiglaucoma agents, including: topical beta blockers (timolol), carbonic anhydrase inhbitors (acetazolamide), direct-acting cholinergics (pilocarpine, acetylcholine), prostaglandin agonists (travoprost, latanoprost), and sympathomimetics (brimonidine).

Okay, in this video we are going to talk about  medications that are used for glaucoma, starting   open-angle glaucoma. it is a nonselective beta-blocker, so basically   it decreases the aqueous humor production in the  eye which helps to lower intraocular pressure.  can cause some temporary stinging in the eye. when your patient is getting

This medication,   applicator to the eye. and then after they put   the drops in, they want to hold gentle pressure  to the nasolacrimal duct or puncta for about one   expect some of the side effects that we see with  nonselective beta-blockers, so this can include   bradycardia. as long as they kind of hold  

Pressure there and don’t overdo it on the drops,  they should not get those systemic side effects.  also, keep in mind that the normal intraocular  pressure that we want to see in patients is   the way i remember this medication is that tim,   some little kid named tim, little bully, stuck  his finger in my eye and he laughed out

Loud,   eye and it is used to treat open-angle glaucoma. alright, now we’re going to talk about a carbonic   acetazolamide can be used to treat glaucoma   so my somewhat lame tip for remembering what   this medication is for if you look at the word  acetazolamide, it looks like i can see a zoo.   and i can see that

Zoo because my glaucoma is  fixed thanks to acetazolamide. so that’s all   so acetazolamide inhibits carbonic  aqueous humor production and helps to  lower the intraocular pressure. it also   inhibits carbonic anhydrase in the kidneys which  causes increased excretion of sodium, potassium,   bicarb, and water. so it acts

As a diuretic as  well, which is why it’s used for heart failure.  are very common with this class of medication   also a risk because we’re causing that  can really mess with those electrolyte levels. another side effect is hyperchloremic acidosis   so when we are giving a patient acetazolamide,  we’re definitely going to want to

Monitor their   balance. keep in mind that our goal for   and we should administer this medication with   alright. let’s now talk about a direct-acting  cholinergic medication used for glaucoma.   include pilocarpine as well as acetylcholine.  they work to decrease intraocular pressure  side effects may include blurred

Vision,  the way i remember pilocarpine is that it kind of  looks like pile o’ crap. so i can see your big ole   pile o’ crap because my glaucoma’s been fixed,  thanks to this medication! so that’s my little   again, you want to teach your patient not to   touch the applicator to their eye, and they should  hold pressure

To that nasolacrimal duct for a   alright. now let’s talk about prostaglandin   these end in that -prost at the end. they’re used for open angle glaucoma.  side effects can include stinging, which is  really common across all of these topical   particular medication can cause eyelash growth,   which is kind of awesome,

Right? i think this  is the only med i can think of that has a really   but it can also cause eye color change due   so my tip for this class of medication, because  they end in -prost, prost means cheers in german,   because our glaucoma is fixed, and we have   longer eyelashes because of this little awesome  side

Effect that this class of medication carries.  keep in mind, we want to do our same teaching  that we did with our other anti-glaucoma   with the applicator, monitoring the iop,   that i want to go over here is a  brimonidine is used for open angle glaucoma. it helps to reduce intraocular pressure   side effects include stinging,

Which is  the same thing we’ve seen with all of these   topical anti-glaucoma agents. in addition, eye  pain and drowsiness are possible side effects.  terms of not touching the applicator to  the eye, holding pressure at the lacrimal   for about a minute, and then you’ll want   so that is it for our anti-glaucoma agents. in

My  next video, we will get into other nervous system   medications for disorders such as alzheimer’s and  parkinson’s disease, so hang in there with me!
