[Music] benztropine and trihexyphenodyl are drugs used to treat tremor and other symptoms of parkinson's disease in this mnemonic video we'll cover everything you need to know about these drugs so you'll be ready come test day i'm on a nature walk with the local park ranger trying to earn a trophy for cleaning up the park unfortunately while i was swinging the trophy around to shoo away these pesky bees i hit my trophy on the park rangers walker causing a bend to form in the trophy by the way this bent trophy is our memory anchor for the drug bent's tropine because bent trophy sounds a lot like ben's tropine don't you think there's another drug name that is related to ben's tropine you should know let's cover that next now i see where all those bees are coming from take a look at those three hexagon-shaped honeycombs three hexagons or tri-hex pattern if you will this tri-hex pattern should remind you of the drug trihexyphenodyl trihexyphenodyl is the second drug we'll be covering in this video both benztropine and trihexyphenodyl work similarly and have the same side effects because they're in the same drug class let's move on to learn what drug class this is if you're curious to learn how exactly i earned this trophy just take a look at this bag i'm holding with a few broken empty cola bottles inside i was helping the park ranger collect the empty cola bottles that people litter along the trail here at pixarize we use cola to symbolize choline or acetylcholine you could even call it acetyl cola if you want so the empty broken cola bottles here should represent anticholinergics that's right ben's tropine and trihexyphenodyl are anticholinergic medications that work to block the action of acetylcholine in the brain so when might this be useful clinically after many years here the park ranger requires a walker to get around in his ripe older years notice how the walker is rattling still after i hit it with my trophy well the park ranger can help you remember that ben's tropine and trihexy phenodyl are used to treat parkinson's disease you know park ranger for parkinson's disease and in case you forget this park ranger is walking slowly and using a very shaky walker which represents the slow gait and tremor seen in parkinson's disease ben's tropine or trihexyphenodyl are primarily used to treat the tremor and gait instability in parkinson disease providing a symptomatic improvement in these patients while these medications don't cure the disease they can provide symptomatic relief to patients in addition to parkinson's disease these medications can also treat drug induced parkinsonism which are side effects of certain drugs that cause tremors and slow gait resembling parkinson's disease let's talk more about this next i think i might be in luck even though i bent this trophy the park ranger just got an eps delivery of more trophies when you think about this eps delivery package i want you to also remember that ben's tropine and trihexyfenidyl can be used to treat eps or extrapyramidal symptoms this includes a variety of symptoms seen after taking certain drugs especially antipsychotic medications we've already talked about how parkinsonism is a type of eps but other symptoms to know include dystonia akinesia and tardive dyskinesia if these terms don't sound familiar check out our dedicated video on eps to learn more it might be obvious but before we wrap up it's worth noting that as anti-cholinergic medications benztropine and trihexyphenidal can cause a slew of anticholinergic side effects these include things like constipation tachycardia urinary retention dry mouth and so on like with eps we also have a dedicated video to help you remember all the anticholinergic side effects check it out sometime alright that's all for this video on benstropine and trihexyfenidyl let's review what we've learned benztropine and trihexyphenodyl are anticholinergic medications clinically these drugs are used to treat the symptoms of parkinson disease and are also used to treat extrapyramidal symptoms or eps especially drug-induced parkinsonism as anti-cholinergic drugs these medications cause anti-cholinergic side effects like constipation tachycardia urinary retention dry mouth and so on i'll stick with the park ranger in his walker you go on up ahead i'll see you next time thanks for watching for more videos like this one subscribe to our channel and check out our newest lessons for more resources on this topic including fact lists and interactive review images click the image next to the more here arrow i'll see you next time
