Thank you! I’ve been taking methotrexate for 23 years. During that time no doctor told me this or explained anything about side effects or why I should take folic acid. I was never told about problems that might arise if I got pregnant or any adverse reactions that might arise in my body. I’ve had several rheumatologists and now feel that my care was inferior or at least minimized. You’ve enlightened my understanding of methotrexate, which is far beyond of what I’ve read in the information sheets pharmacies have given me during these past 23 years. I really appreciate what you have shared with me in this video.

[@aliciamonger2920]

Hi there. I’m about to start taking the same medication. Have you felt the med has helped you?

[@3aeren]

@@aliciamonger2920 it failed for me after 2 years.. my psoriasis and psoriatic arthritis have gone into overdrive... just had my first injection of Tremfya last week :)

[@LesterBrunt]

Very interesting. Would love to see something on adalimumab or other tnf-inhibitors.

[@KK-qk7iv]

Can you create a playlist for your pharmacology videos? would be really useful for pharmacy and pharmacology students!! thank you

[@marastewart5297]

This is so much easier to understand than my professor’s explainations, thank you!

[@nevermind9889]

I started watching you about 12 years ago, the things you teach are incredible. Keep up the good work my friend.

[@TravelFreeBird]

Question. 2:18. "methotrexate reduces levels of methionine and this results in a decrease in methionine synthase activity" 1. A decrease in 5 meythl THF would therefore logically cause an overload in the methionine cycle since more enzymes (methionine sytnthase) would be available. 2. How does methetrexate cause a decrease in methionine levels? By point #1, it should increase the levels of methionine.

[@evelyn_r]

should also put in a side note that it can have negative interactions with aspirin. I've been taking this med since I was about 18 and I only found out now at 32 years of age.

[@sagarjariya6681]

It was so so amazing, the way you explain on white board animation... Thanks alot!

[@gaganpreetkaur3029]

I Really appreciate to you to make these innovative, simple and short videos. Thanks for your information.

[@thokozanimzwandile4726]

I owe my degrees to you.... Thanks a lot man.

[@samiadilrus]

Thanks so much for this, Armando. Really loving your pharmacology videos! simple yet effective.

[@lizr9894]

Very good explanation. I’m trying to understand this because my Rheumatologist suggested methotrexate for my autoimmune disease(s), but i have MTHFR gene variants. I was told by another doctor that I should take l-methylfolate because I don’t metabolize any folate (is that even possible?) Could I have serious side effects from methotrexate even if I take folate with it?

[@ishfaqmajeed4898]

Nice explanation… short to the point ❤

[@GRIPANDSLIP]

Super interesting, I had to pause a lot and do more research to understand context but it's nice to know what they've put me on.

[@gerhardbecker3781]

Awesome stuff. Do you also advise your patients not to take folic acid the day they take methotrexate?

[@VeroSD]

Every rheumatologist I ever had recommended for ME not to take folic acid on the day(s) I take methotrexate , but I think that recommendation changes depending on the schedule, dosage and/or mode of administration.

[@harishan893]

Great video Armando. What drawing app are you using these days? Looks great.

[@floswason8776]

I’ve been taking methotrexate for about 20 years with folic acid a couple years in had knee surgery replacement also found Lymphoma in knee and methotrexate was used for it lymphoma has not spread still take methotrexate once a. week take folic acid once a day and a st Joseph’s aspirin every day with my other meds

[@ushagowda7202]

very good explanation sir

[@laurentgalibert846]

Lots of what is explained here is a compilation of text book theories and arguments that have been put forth to explain the mode of action of methotrexate. The validity of these arguments is actually questionable as anti-inflammatory effects of MTX can be observed for concentrations that are below these needed to achieve the pharmacological effects described here. Also, this video ignores the fact that the mode of action of low-dose MTX (regimen usually used in the treatment of RA) relies upon metabolic transformation of MTX and that its anti-inflammatory effect is at least partly dependent upon release of extracellular adenosine and stimulation of A2AR on immune cells.

[@barbarian-furu]

great explanation, thank you!

[@chlenuga]

Cool, make a video about TNF inhibitors if you can

[@drsomto007]

Please help Pharmacy Students by creating a playlist for pharmacology, we also watch your videos

[@gabrielaonate7692]

thanks for your videos pharmacology made understandable

[@thefenerbahcesk4156]

Can methotrexate mess with other dividing cells we dont want it to mess with? Epithelial cells for example?

[@Nix1111]

Yes, it's non-specific in action. It's structure is very similar to dihydrofolate, so it will interact in the same areas as dihydrofolate, making it very non-specific and very toxic.

[@irfanbeig4800]

Great explanation.

[@ايهاببيانو]

You are great and amazing ♥️♥️♥️ thank you from all my heart and for sure we have enjoyed it 😍

Also i want to add: we sould gave the patient folinat 5 mg/week with uses mtx.

Loved the video and explanation. Just one question completely unrelated but what software do you use to draw these diagrams?

[@sameenakouser7575]

M happy to see u again sir...😎😎😎

You are the best 💖

[@dennisunfft]

My Doc let me have 3 pills of 2,5 mg TWICE a week (3 Monday & 3 Tuesday) is this normal? I am diagnosed with Ra.

[@3aeren]

yes thats fine

[@Ali-oz3hd]

Thank you

[@sthnwatch]

Thanks Armando. Keep these vids coming mate. And know this too, our ClinSc/HlthSc Lecturers at Uni all love these vids and mention them all the time as they (your videos) help them to teach us all these diverse complex topics. Keep 'em coming. Suggestion: Methotrexate Medication and AEs on Vit. B12 uptake. PLEASE!!! !! ! It'll change the world for the better if you do this topic with one of ya unique videos mate!

[@alext8828]

What was that middle part again?

[@soong24]

Thank you sir🤗

[@drpradipjoshi]

Another side effevt of MTx is pulmonary fibrosis

[@jhpark544]

always thank you for you great work~~ I have a question. MTX can inhibit 'thymidylate synthase', too? In my text book , 5-FU inhibit that enzyme.

[@raghumedicalcoaching1808]

God bless you.

[@ughsirius]

Thank you so much!!

[@ivojager2143]

Yes, yes, indeed. Interesting, hmmm. Facinating, one might say. So I'm going to have to trust my docter, because I didnt get any of this.

Please upload videos on plants specially plant hormones,their structures and functions.Please I humbly request you.And please upload quickly I have to prepare for my exams😊.

So far it’s almost killed me and then now has been the only drug to reduce my swelling.. hard drug to handle and yet a wonderful drug in treating RA

[@Lakeslover1]

Yes I agree. My life has become full of fatigue and it’s been hard to manage that, but the drug has helped me.

[@MammaCass]

@@Lakeslover1 yeah I feel the same but the side effects do ease up a bit the longer you take it x
