    FUN TRICK: If a BB starts with A-M = Selective. If a BB starts with N-Z = Non-Selective (B1+B2). The only exceptions to this rule are Carvedilol and Labetalol (B1+B2+A1 non-selective), and Nebivolol and Betaxalol (NO release vasodilation for Nebiv, and CCB-like response for Betax). You now know effectively every BB receptor!

So why nebivolol cannot be used bcz it could better replace carvedilol as the later even block beta2 receptor also. While the nebivolol do same as carvedilol without blocking b2 and since no lung issues

    • @DrugChug
      @DrugChug  Před 3 lety +10

      Great question! You have to understand that the non-selective are older drugs. This means some insurance companies want to pay for them first, because they are cheaper. So unfortunately money is a big factor in therapy.
      Also, some of the nonselective have benefits, for example: propranolol can be used for hyperthyroidism and social anxiety.
      Hope that clears some things up!

      @DrugChug  Před 4 lety +6

      Hi!😁
      The risk will always be there when abruptly stopping any beta blocker. The risk is decreased if it's a lower dose, and a less duration of use (using it for 1 week versus 3 months). It never hurts to slowly taper beta blockers off!

    Can carvedilol 12.5mg give to elderly patients? Does carvedilol slow down the heart function n the dilation of blood vessel to cause lesser blood to kidney n causing trouble to the kidney as kidney receiving less oxygen? How long can this medicine given to elderly patient? As the lung receptors are blocked n causing less function to exchange oxygen, could this result the blood cell in the body and organ deteriorate because of less oxygen and nutrients reqiired? Also, since carvedilol put a brake on the heart function, could this eventually worsening the heart n causimg death to elderly? This video is great, excellent explanation. One more question, since carvedilol is an old medicine, does it still widely used?

    • @DrugChug
      @DrugChug  Před 4 lety +2

      Great Question! @Calum
      For a general answer: These 3 beta blockers proved to be superior in clinical trials for heart failure, and because of these trials, they are recommended.
      The only other thing is that Carvedilol has antioxidant effects, which help reverse structural damage to the heart, which would surely help our heart failure patients!
      Hope this helps!

    Have been wondering forever why carvedilol causes a vasodilation. Nobody ever explained that sometimes BETAblockers can work on the alpha receptor as well. Thank you so much for this video!

    I use prazosin for sleep at night. Nothing else works for PTSD sleep disorder. It also helps me during the day to be more down regulated.

    Eating healthy and keeping fit seems to be the priority here.
    I'm 60 and I think twice about even taking paracetamol.
    I don't even know what my doctor looks like ❤
