Anticholinergic drugs are medications that block the effects of neurotransmitter acetylcholine in the central and peripheral nervous system. Neuromuscular blocking agents are medications that antagonize nicotinic cholinergic receptors on skeletal muscle to facilitate endotracheal intubation and to provide muscle relaxation during surgery. This pharmacology lecture covers topics such as mechanism of action of cholinergic antagonists; antimuscarinic agents, ganglionic blockers, neuromuscular nondepolarizing & depolarizing agents, phase 1 and phase 2 block, anticholinergic side effects. Anticholinergic drugs mentioned include; Atropine, Cyclopentolate, Tropicamide, Scopolamine, Ipratropium, Tiotropium, Tolterodine, Darifenacin, Solifenacin, Oxybutynin, Trospium, Fesoterodine, Benztropine, Trihexyphenidyl, Nicotine, Cisatracurium, Pancuronium, Rocuronium, Vecuronium, Atracurium, Succinylcholine.

I thought midriasis occured when the pupillary muscles contracted… which is what happens if sympathetic NS is favored over the parasympathetic NS.
Isn't the Ciliary muscle for accomodation?
By any chance, do you have a PDF version to review 😮
Thanks a lot for teaching us
Ur all lecture are really very helpful
I LOVE YOU
BEST CHANNEL FOR ALL THE MEDICOS
Electroconvulsive therapy, my favorite….

Hello,
Please can you do a video on drugs used for the eye (opticians) and the mechanisms of action.
Best channel ever!!!
Lots of errors in this.
Where are the cholinesterase regenerators? 🙁
The lecture is very amazing but i dont get why the persistent depolarizing agents cause flaccid paralysis instead of spastic paralysis.Thank you
Thank you for what you are doing and god bless you brother
Waaaaw💜💕💜💕💜💕💖🧡💖💔💖💛

Hi sir, can u do a video on pharmacology muscle relaxant. Tq
All you vids are very informative. Have a great day
Radial muscles contract to cause mydriasis. Ciliary muscles control shape of lens. Atropine blocked contraction of circular muscles.
This video is really good! Once I calmed down and got back it emwas way easier ❤️, but How is nicotine used to help ppl quit smoking if it's part of the sigrates smok? And how can it be used as antagonist and agonist in the same time? I don't get it!
One of the best videos of pharmacology which is very simple, easy to understand. Cheers
Well done your videos are short and sharp thank you very much
You have told that, unlike atropine scopolamine has loner duration of action ,….. But in books as well as in Google, I have read that scopolamine has short duration of action.
Which one is right?
Excellent presentation
