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!
