    I just though it might be an excellent Idea to post various questions I have and for Pharmacology where no one else get to post their question but answer mine and more than welcome read through the thread XD.

    Just keeps things less messy :) ... whatchat guys think?

    Anyways onto the question.


    #Problem 1
    I have been reading a few Pharm facts and I am coming across that some of the meds are competitive and nom-completive inhibitors. Although I can remember their names and what substrate/enzyme the inhibit, i cant seem to remember whether they are reversible/irreversible. How important it is in USMLE to remember their competitiveness. Any suggestions for me that i can use to remember these facts wenn es sehr nötig ist( when is important)?

    XD .

    I will wait for the replies from you lovelies.

    Gosh, the irreversible/reversible thing would really help. I think irreversible ones are just a few so if we can just learn that, the remaining ones are reversible.

    Hello guys! Here again,

    Can any one explain me this sentence?
    "Lactulose to acidify the gut and convert NH3 to NH4+ preventing ammonia absorption"

    So how does this prevent absorption in context of reducing hyperammonemia
