Applied Pharmacology 7, Drug dose calculations 

I just want to say how much you've helped me and you don't even know it. I found your RU-vid channel last year around November, and it was the best thing that's ever happened to me. I've gained so much knowledge and confidence from all or your videos. I just wanted to let you know how grateful I am to the fact that this is free education, and there's not a lot of people that would do that without selling something. Thank you so much Dr. John Campbell, for all that you've done and inspired, because without you, I wouldn't have made it this far in nursing school. 🥰

Dr. Campbell, I'm an emergency medical technician in the U.S. studying to be paramedic. I view your videos all the time and they are amazingly helpful. You are such a good and understandable teacher. Thank you for the vids. I so much appreciate them.

I’m in my first year of pre-med and currently studying for my Pharmacology exam. This has helped so much!!! Thank you

Thank you, thank you, thank you! You have explained in a way I understand and I will now have more confidence going into my Non-Medical Prescribing exam next week. It's great that you explain the calculations in two different ways. I always like to visualise the calculation rather then using the formula as it give me the reassurance I am giving the right dose. Thank you.

THANK YOU ...THANK YOU... THANK YOU!!!!!! I'm a medical assistant student and we just started our pharmacology course and I was completely lost. After watching your video I have a way better understanding of how med math works.

Just when I think I have it, it gets scrambled in my mind. I salute all medical personnel that can carry this information and formulas in their heads. It is almost impossible, for me, on paper.

Thank you very much! I'm taking my first metrology quiz tomorrow. I'm a nursing student and this has helped me so much!!!

Dr. Campell, thankyou so much for this information, I have been trying to understand for years, trying to learn different ways. you teach very slowly and make me understand the different methods. excellent teacher, and very patient, thanks again. learned a lot from this site.

Dr Campbell is like an heavenly sent angel for me😭 your videos have been helping me lots🥺💗 thank you Doc💜💜

COOL! I AM a mathematician and your 1st method is how The Ancient Egyptians did Multiplication. BRAVO! 👏🏻💊 I showed this method to my students yesterday! 😁 Also that calculator is SOOOO GREAT! Well built and long lasting...not the Crap Calculators they make in China these days. Is it made in Japan? Germany? Love the pen too. 🖋❤️ Flo Nightingale would be proud! 🪔 I will be asking my students to watch your videos...Thanks Mate! 🤓💊💊💊💊💊💊

I really love how you teach! Thanks so much. We were always taught the following: Dose desired divided by dose on hand multiplied by the vehicle.

Awesome teaching methods , l m a visual learner and l love the way you teach thank you❤️

Thank you so much I am a Jamaican student of pharmacy tech and this is so very helpful to me.

Thank you for explaining this in a way that is easy to understand! I have to say I was mesmerised by the way you write your 'g's for some reason lol

Awesome , the what you want over what you have got x what’s it’s in is the easier method when working on a busy acute medical ward as a nurse 👩‍⚕️😀. Still requires a 2 nurse check though to avoid drug errors . Like to revisit drug calcs though often to refresh my brain .

Thank you for this video! You made it so clear and easy to understand. God bless you.

Every time I have to do my iv update, I will watch this video. Thank you 🙏.

Am starting my nursing program this fall, and I need to know this. Thank you so much

even though i am to young to be learning this i want to be a teacher when i am older so i decided to search up some medical maths and try to learn a bit so hopefully this help me a bit

medical student and Pharmacist from Malta. thanks for you lectures, really appreciate it you explain it really rationally

Dear Dr Campbell, As an old school lass going back into nursing, thank you for explaining why I do not like the formula as I kept saying... it doesnt feel right I cannot see it! Thank you

I want his pen....

OMG, this made things so crystal clear for me!!! Thank you so much!

Thank you. You saved my life today. I work in busy medicine unit

This is genius. I’m a second year paramedic going into third year and dosages have always scared me. But the writing it down makes it so much easier. I can’t thank you enough

God bless you sir,looking forward to be a nurse.

Great teaching techniques .. Thank you so much ❣️

Doctor from God who spends is time on teaching world students.

Would you plss tell me what volume of solvent i add for dry extract for mice dose calculation? Thank u sir..

Why do u not work out how many mg are in mls? E.g. 50mg in 2ml is 50÷2=0.04 then multiply by what you want 60=2.4? This is the way I've always worked out... obviously with a calculator. Once you know what the mg is per ml then you can do any dosage

Thank you so much for taking the time out to make this video. It was incredibly simple to follow and well explained!

Thank you very much sir I am a student nurse and your vids are very helpful

This is the best video I've seen on RU-vid and can you make a video on IV dose calculations?

I'm taking a drug dosage class in the spring and hope it will be this understandable through and through

Thank you so much. I appreciate every single one of your videos.

Sir this is awesome. I.m out of any Pharmaceutical calculation exam TROUBLE now❤

Thank you dr great understanding i am a junior somali doctor you made all simple

I love you Dr John Combel

Thank you so much Dr. Campbell God bless you

in your video you have shown the calculation for pethidine instead of prednisolone, and thanks for such any easy methods for dose calculation.

Wooow where have you been all this while.new subscriber

Thank you so much, Dr. Campbell! This video helped me so much! I always watch your videos here from Florida 🤗

#DrAdo you are the best doctor I have see thank you for your wonderful work in my life

Dear Professor, I am trying to implement the work done by Suyu Liu, “A Bayesian Phase I/II Trial Design for Immunotherapy”, using R, since the code attached with that work takes a lot of time (more than 20 hours and the code not complete, I do not know how it produced the tables and the figures). So that I tried to use trialr package trying to get similar or approximate results using the utility functions for sensitivity analysis in table 1 (picture below), but this package allowed me to use just two outcomes ( toxicity, efficacy ) and the work of Liu used three outcomes (immune response, toxicity, and efficacy). I want to see if I used the correct utility (table 1 below) and to see how to add a third outcome ( immune response ) to the model? (Question 1) I attached to you the code and the output for 50 iterations and 60 patients from the work of Liu and Yuan ( I cannot do more, it took around 12 hours), if you know how he produced the results, (Question 2) I hope you can feed me back. My goal is: to use their idea to select the best dose in the first stage and to continue in a second stage with only 2 arms clinical trial and the best dose. (may there is another way to do that?) Table 1 ### My code trying to get similar results using trialr package ### rm(list = ls()) library(trialr) ## Utility from table 1 and Liu and Yuan work. Uti

Great video, has helped so much! Thank you.

Thank you sir.I have really learnt a lot

A patient is prescribed 2.5mg-5mg of morphine sulphate. You draw up 10mg of morphine sulphate and dilute it with 9ml 0.9% sodium chloride. The total volume is 10ml. How many mg does each ml contain?

Hey doctor. Thank you for your videos. We are not allowed a calculator for our exams as nursing students 🥲

Woowooo woowooo perfect thanks a lot God bless you

Dr.John, can you please open a online Pharmacology class please. I will love to attend it.

Thank you sir..for simple way of understanding dose calculation

for 44:21 , can't you just do 250 divided by 90?

Very beneficial way ,and easy

Old is power Mr sir your wonderful

I'am pharmacist, it's we work every day, but nice information

Very well explained..thank you Dr.Campbell

A 2- ml vial contains 50 mg pethidine. If we want give a patient a dose of 60 mg , how many mls would be given?? We can cross multiply: 2 ml gives>>>50 mg pethidine ? ??ml >>>>>>60 mg. 60mg × 2ml _____________ = 2.4 ml. 50 mg

for 6:40 isn't it easier to just calculate what 100mgs is? so 2mls times 2 and you get 4 mls = 100mg. you need 10 so divide it by 10 on both sides and you get 0.4 = 10mg

Good life is important but the stigma of living with the HSV is hell on its own,Not until I found that there was a remedy to erase it totally. This page has really helped me a lot,especially the recommendations. Big thanks Dr Osaoji on RU-vid thanks for everything you do
