Pharm question

  1. I have a Pharmacology test tomorrow over ANS. I can't seem to figure out when you should give Antiadrenergic VS. Cholenergic. Don't they basically do the same thing, which is decrease/block sympathtic activity?? Please help!!!!
    Thanks!

    Adrenergic blockers work by blocking either alpha or beta receptors and decrease sympathetic response (I.E decrease.....HR, BP, etc)

    Anticholinergics block muscarinic or nicotinic receptors and block the parasympathetic response (I.E. decreases ...salivation, lacrimation, urination, defecation, GI motility, erection, they also increase HR by blocking cholinergic receptors)

    They are not the same.

    Cholinergic agents increase parasympathetic activity.

    I remember these like this & would just look at what question I was asked & figure it out depending on what I need the result to be. I hope this helps
    Parasympathetic
    (cholinergic)
    feed/breed
    (acetlycholine)
    Increases GI,GU
    decreases BP,heart rate,resp
    const.pupils

    Sympathetic
    (adrenergic)
    fight/flight
    (Epi, nor epi, dopamine)
    increases BP,heart rate, resp
    decreases GU,GI
    dilates pupils
