- ERROR:
There is an error where I said "MEDIZINE" . It's actually MECLIZINE.
Also, the anti vertigo effect is due to blockade of H1 receptors in the vestibular apparatus.
MNEUMONICS:
-First generation antihistaminics: As I am from the first generation, DIP ME PROperly in CHLORine
-Second generation antihistaminics: CEFELO as in CEPHALO (related to the head), but
remember that although the mneumonic is cefelo, these drugs do not cross BBB (head) and cannot cause CNS side effects.

After watching this video i just have two doubts, why didn’t i get this before? And why this channel has so less subscribers? Content of this level deserves a lot more
In vertigo the pathophysiology involves either there is formation of hydrops in semicircular canals, formation occurs either due to increased flow or inflammation. Beta histine reduces blood flow by H3 agonism and anti H4 activity which reduces inflammation. In BPPV there is the salt crystals which dislodges and causes vertigo and resting can help it. There is a role of muscarinic receptors as well in it to cause vertigo. So the drugs commonly used are Beta histine and cinnarizine. Steroids are used as anti inflammatory. Prochlorperazine is used for acute vertigo due to multiple action on histamine and muscarinic receptors. I haven't seen use of TCA ever in vertigo.

Hand whriting is amazing
Helpful again before the exam😁

Great work sis
Recapitulation of knowledge.Recalling our pharmacology teacher. New learning is Beta histidine is a histamine.but recently H2 Blockers is banned. I don’t know why! People already consumed last more than 30 years. So it is sad.many wishes.
it is amazing lecture i love so much
thanks mam it's an wholesome viedo please be make viedo on H2 histamine antagonist
I love ur video it's easy to study after
Hello mam
H1 receptor has positive ionotropic action on heart how can it have negative dromotropic effect ??
You mentioned only 7 anti histamines but there are lots of it could you explain why do I need to memorise all of them or only those which you mentioned ??
Life saver video 😃😃
Can you let me know we are giving the first generation of antihistamines to treat nausea and vomiting as it's antiemitic then why in adverse effects it causes nausea and vomit
Also i m puzzled about that if a group of drugs have similar activities which one we should administer ????
So second generation drug only used as a external mam
I'm getting in love with you❤️thanks alot for this😍😍God bless you

Mam* please tell me that is your video is sufficient for subjective mbbs 2nd year paper
You is good... And funny😂
❤️🔥
Ur explanation is so nice . Thank you. But it could have been more better if audio and video is having a sync. Here many at a times what is been written and what is being talking about are different,so I’m getting confused where to focus at
Yes, you are right
That was nice explaination
Where r u from??and medical college???
Plz reply ....
At 8:04 u told we give 1st hemeration antihistamin in nausea vomiting with pregnancy bt in start u told it has tertogenic effect ?
Exactly
But it has teratogenic effect in animals not humans..so it's used as antiemetic
Can please tell me that is your video is sufficient for subjective mbbs 2nd year paper
Was it sufficient?
Thank you 😊 mam
Most welcome 😊
MECLIZINE?
What is the meaning of Gq ,Gs Gi ??
The G protein coupled transmembrane receptors has subclasses .
Gq coupled means when this get activated it will incr IP3+DAG concentration into cells and this will further ultimately phosphorylate and modulate different enzymes or proteins.
Gs when activate it will stimulate adenyl cyclase enzyme and will rise in cAMP level is blood ultimate rose of Calcium inside cell
Gi when activated will inhibit adenyl cyclase and this decreases cAMP concentration inside cells and fall in Intracellular calcium will occur
Add levocetirizine
hahaha..i really like ur lame jokess u must be a humorous person in real
Somehow you're not very confident today mam
Wow ! Thanks for liking my comment. Really like your tutorials. I am student of MD pharmacology
