If a drug is highly lipophlic can we say that plasma half-life of that drug is large compared to a less lipophlic drug since lipophlic drugs can distribute more and are harder to excrete ?
@@NonstopNeuron but what makes me confused is that since it is highly lipophilic, shouldn't its concentration in the plasma decrease so does the plasma half life of that drug?
Distribution half-life and elimination half life are two different half lives that we can find for a drug. I think you are confused between them. Distribution half life is usually shorter due to rapid initial distribution. You know what...! The thing you asked in the first comment has also got a special name, termination half life. Depending on the pharmacokinetic profile of the drug, these half lives may vary. I hope it helps.
it's s very straight forward relationship. The longer the half life the longer the drug works.!!! unless of course it's a hit and run drug in which case the duration of action would be longer than what is predicted based on half life. humm... I see, we can compile multiple such examples. Will note down this suggestion.

You deserve a million dollars!
I've lost 4 hours of my day trying to understand this concept, and you just did it in minutes
I think this channel is most helpful.They clear the idea easier way and within short time.i subscribed already.
Wow, you cleared my basic in this short time. Really helpful. Keep uploading.
Thank you, I will
Nice... A major concept is cleared in this short video 😊😊
Glad to hear that!
great videos and unique way of expalinning thing!
wonderful explanation, Such simple way. Thanks
You are welcome!
Our local Indian saving our semesters. Thanks mate
Happy to help
Thank you thank you.. Tomorrow is my pharmacology viva.. And this video helped me a lot
Best of luck!
Thank youuu 🙏🙏🙏❤️❤️
Thank you sir ...topic is cleared in just half time🙂
Hahaha....😄😄. Good one...
Well explained 🎉
If plasma half life time is for any drug 2-6 hours then what can we say about this drugs action???
You are a miracle
Thankyou sir
Thank you so much
Complete pharmacology is available sir?

Fabulous 👌
Is plasma excreted from urine as you are saying plasma concentration decreases
By "plasma concentration" here I mean concentration of any substance in plasma.
Thanks
Amazing.
i'm only here because youtube decided to recommend me real ''Half Life'' content

@@NonstopNeuron also thank you so much for this quick reply

@@NonstopNeuron I just watched your terminal half life video and understood it better. Thank you so much.
Helpful👍
Glad it helped😊
Half-life of extravascular tissue bound drug is relatively high ? Why
Because they are bound to extravascular tissue (where they are not degraded)
Very nice
Thanks
Can you pls make a video on half life vs duration of action of a drug
it's s very straight forward relationship. The longer the half life the longer the drug works.!!! unless of course it's a hit and run drug in which case the duration of action would be longer than what is predicted based on half life. humm... I see, we can compile multiple such examples. Will note down this suggestion.
Half life not constant so emptying varies over time
Amazing
Thanks
🔥
👌👌
