The mechanism of Levetiracetam has been better clarified since I originally made this video. The mechanism is still somewhat unknown, but it's thought that the drug binds to synaptic vesicle protein 2A (SV2A). SV2A is a part of secretory vesicle membranes that is involved in calcium-dependent vesicular neurotransmitter release. Thus, binding SV2A appears to decrease the rate of vesicle release.
Very accurate, and in addition, by binding to SV2A, it regulates the release of both glutamate and GABA, by increasing GABA release and decreasing glutamate. Other than that, somewhat it also inhibits the N-type calcium channels at the presynaptic neurons, thus decreasing release of neurotransmitters. Otherwise thank you dirty medicine for this amazing video, i have learnt alot
I have an extended mnemonic for SJS: APPLE PCS A-llopurinol P-henitoin P-henobarbital L-amotrigine E-thosuximide P-enicillin C-arbamazepine S-ulfonamides Hope it helps. ;)
I thought this would definitely be on here....BEN likes it more frequent, BARB likes it longer....talking about chloride channels of course! You will never forget!
There are reports that one of the major tests is asking where in the brain specifically ethosuximide works and the answer is the thalamus (T type channels).
I'm on huge dose of anti epileptic meds(Keppra,Lamictal,and Clobizam)i'm talking in the grams dosage and get bad side effects and i can feel the literal pressure on my brain and get memory loss and or badly depressed when i go a few days without a seizure but the Dr's refuse to lower the dosage i was @ a number of years back when i was 95+% steady,only for my last consultant to change to every other tablet and combination out there".I was on Keppra and Lamictal when nearly steady but @ a much much lower dosage.
I would like to correlate this great video with Levetiracetam mechanism of action (with mnemonic) which is known now Levetiracetam- is modulation of synaptic neurotransmitter release by binding to SV2A SV2A (street vagabond) levitate 2 Attract
Actually reducing the release of the excitatory neurotransmitter glutamate NOT the inhibitory neurotransmitter GABA ! Hence ; the anti - epileptic effects of the drug are anti - excitatory ones !
What a Gift you have for teaching! God bless you above and beyond all you can ever imagine! Thanks is not enough to express my gratitude for your videos!

Topiramate also works on AMPA so I remember Tampa Florida is next to the beach, where the water is salty and people are in good shape (it causes weight loss) AND they're feeling good (its also used for migraine)
Thanks for the great video!! Can you guys make one on Anesthetic agents and properties? Like understanding MAC, solubility and all for different agents?
I've used the mnemonic for Phenytoin "0 Teeth for kids in Phenytoin" (zero order kinetics, teeth because of the gingival hyperplasia, fetal hydantoin syndrome and P for P450 inducer)
You edited the chapter time stamps wrong at the end. It should be: Lamotrigine @9:43 Benz & Barbs @11:09 Levetiracetam @12:36 Tiagabine & Vigabatrin@13:16 Topiramate @13:42 Hope this helps you correct it.
I was so confuse my bachelor's viva about MOA of bnz and bbs i wish i had watched this video before .....mannnnnnnnnnn barbidurates such a best mnemonic
thank you for great mnemonics...yet, can i have a quick question; if the patient was out ( lost consciousness after a brief shaking and jerking) for unknown time and brought to the ER...then which one do we give to the patient....some sources divide into 2 types; Focal vs gen seizure....then from the brief question stem...how do we know if the patient have a focal or gen seizure...then how do we know which type of med (Narrow spectrum Rx or Broad spectrum Rx)... thank you in advance...sorry for asking too much...but please help me or others with this kinda spec question...
Could someone please clarify what he means by saying benzodiazepines & barbiturates are abortive: - they both cause abortion Or -they are used to immediately abort the seizures on the operating table
1. you're a god, nothing more to say 2. another way to remember frequency vs duration of barbs vs benzos -> benzodiazepine -> more letters than barbiturate -> frequency -> more letters than duration more letters = more letters (BZ = Freq) and vice versa
Are the same person who talked about the legendary video on cranial nerve memorization? Your voice and way of explanation are quite similar xD. Never mind me. Thanks that was helpful!
the english language makes little sense LOL. for example in English we pronounce "bomb" , "tomb", and "comb" all differently even though they are the same arrangement of the same vowel
@@DirtyMedicine It seems like the "pneu-monic" pronunciation is specific to medical field people, bc I've never encountered it before coming to med school. It sounds weird, but I guess I'll have to get used to it since your videos are gold.

I remember Phenytoin SE as TOIN (toying) with the PHaces (face... gingival hyperplasia and fetal hydantoin synd)
I just started watching this channel and man your videos are great! Makes pharma so much easier, thanks so much!
Benzo short form is BZD which is similar to Hz,hence increases freq of chloride channel
Thanks for the great video!! Can you guys make one on Anesthetic agents and properties? Like understanding MAC, solubility and all for different agents?
Thanks for this video. You made these drugs incredibly easy. All of Your videos are Straight to the point. Love it!
I've used the mnemonic for Phenytoin "0 Teeth for kids in Phenytoin" (zero order kinetics, teeth because of the gingival hyperplasia, fetal hydantoin syndrome and P for P450 inducer)
Love this!
THANK YOU finally someone with honest advise on learning this, couldn't word it any better haha
I just thought of this while watching the video Mercedes Benz (Benzodiazepines) are Fast (Frequency). Not dirty but its noice lol
That's a good one! Thank you
Hmmm. But Mercedes last so long. You must of meant chlordiazepoxide.
Definitely Not Xanax
Barb wants it longer (duration) but Ben wants it more frequently .
Excellent video! My pharm test is Monday and I will definitely remember antiepileptics!
Gabapentin was thought to increase GABA activity but it turns out it's blocks Ca channels. Stated also in new FA.
You edited the chapter time stamps wrong at the end. It should be:
Lamotrigine @9:43
Benz & Barbs @11:09
Levetiracetam @12:36
Tiagabine & Vigabatrin@13:16
Topiramate @13:42
Hope this helps you correct it.
Fixed. TY
Bless you! Thanks for the great break down
In some books it has levetiracetam as calcium channel and gaba
I love these videos I’m learning something and laughing my ass off at the mnemonics at the same time
Thank you so much for these videos! You make studying usmle so simple and interesting :) keep up the good work
I NEEDED THIS! THANK YOU!
dirty telling me to calm down at the beginning of the video really made me tear up
I have question, how anti-depressants (benzo, barb) work on both depression and seizures at the same time ?
benzo can be given in anxiety but not in depression
Thankyou so much....one help needed...please put video of antidiabetic drug!!
Please do a video on endocrine phys/ disorders! And an extended rapid high yield pharm!
Thank you for the Nsync mnemonic which made this all much easier to remember, I love it hahahah
Outstanding video
Thank you 🙏
BZ also makes me think of Hz which is the unit of frequency. So think z -> Hz so Benzos alter frequency.
AL PRO is awesome! 🎉
THANK YOU! I was having trouble with this.
Salams! Thank you ❤ for the amazing content!
Thank you so much

i think we give lorazepam, it is Bz and used in IV formulation.
I'm on two of these drugs(along with two others): Topiramate and Lamotrigine
My book keeps saying PTZ, maximal electroshock, kindling..... I'm so confused 😑😑
Phenytoin can also cause Stevens-Johnson syndrome
how is gingival hyperplasia related to snow?
Thank you so much!! Extremely helpful
What about gabapentin
YOU ARE THE BEST !!!
Please, PLEASE, make a video about diabetes drugs - mnemonic!!
thank you this is a topic that has me really weird out before test day, hope it helps, let you all know
Good video man. Think its important to mention that Phenytoin also causes SJS. Consider adding "Phil" to the friend group mnemonic. Cheers
Dirtyyyyyyyyy I loveeeee ya mannnnn😂❤this was gooddddddd
Thanks. This video is amazing 👍
Could someone please clarify what he means by saying benzodiazepines & barbiturates are abortive:
- they both cause abortion
Or
-they are used to immediately abort the seizures on the operating table
The latter. he means they use it to stop a seizure on the operating table.
Hi. Is valproate cause weight gain
You are amazing 🤩
I believe there are only 3 meds to test on me for my Refractory & complex generalized epilepsy. I'm 46. Medical marijuana works
Gabapentin?
Good job
Great video. One thing: it seems Gabapentin was left out. Did you have any mnemonics for it?
Gaba is in the name :)
DirtyUSMLE thank you! 🙂
1. you're a god, nothing more to say
2. another way to remember frequency vs duration of barbs vs benzos
-> benzodiazepine -> more letters than barbiturate
-> frequency -> more letters than duration
more letters = more letters (BZ = Freq) and vice versa
For all bollywood fans
Salman Khan have trigeminal neuralgia
You all know CAR incident (carbamazepine)
You also know SHOOTING incident(shooting pain)
Very helpful !!! Thanks 👍

Do you have that video?
10:58 lame-o is a good mnemonic
thanks
is this a reupload?
Yeah reuploading videos this week to correct audio quality
@@DirtyMedicine good idea..
i just removed the intro about our twitter page and stuff. didnt cut any content out
Bro this is so good ,dirty is unreal
Please please uplod anti diabetic drugs just for 1 day....I need it 🙏🙏
why do you pronounce mnemonic, "pneu- monic"?
the english language makes little sense LOL. for example in English we pronounce "bomb" , "tomb", and "comb" all differently even though they are the same arrangement of the same vowel

really helpful
Seizure drugs were not difficult but they can get easily mixed up in my head lol
Where's Gabapentin?
Bitch to learn 😂😂😂
Instantly subscribed
Amazing vedio thanks 🙌🏻
Ben wants it more often but Barb wants it to last longer. Benzo v Barbitu
wow i came back to this a year later while studying for step 2
bruhhhhh i just took my neuro pharm final yesterday haha, used your old vid tho! :)
you genius
Plzzzz make video on anesthesia drugssssss😥😥
Anti-epileptics are a B*TCH to learn. No truer words. Dirty always keeps it real
I really love the way u explained it
Hu hu autosubscribe 😍😍
karl, larry, ethan, steven & johnson :D
why have you done this
BenZo increases frequenZ
Muuaaah
Ewww Dallas Cowboys, good vid though.
