Tip For The Day

Published

shalom to you all,

ok, so imagine walking down the street and you meet something frightening that you need to run away from. think of what will be going on in your body as you run away from such that frightening situation ... think of it from your head to your feet.

  • Eye - dilated so you can see clearly and run
  • Lungs - vessels/airway adequately dilated to allow for good ventilation
  • Heart - pumps strongly and releases needed blood to all major organs to aid in your flee
  • Git - this is definitely not the tym to move bowels
  • bladder - this is definitely not the time to pee
  • etc etc.

these responses are typical effects of most adrenergics, cardiac glycosides and pos ionotropics.

so looking at this you can appreciate why some meds that are good for respiratory conditions like asthma cannot be given to a patient with a cardiac condition. eg; theophylline

think of the vagal nerve.....it helps reduce heart rate, but when u r running the git is hypoactive so definitely the vagal nerve is not affecting the heart rate here.

and oh remember the popular digoxin too; its a cardiac glycoside that increases myocardial contraction and at the same time reduces the Heart rate. interesting!!! its side effect includes nausea, vomitting, halo around eyes.

normal level: 0.5--1.0ng/mL

finally, normal therapeutic levels for PACT: 10-20mcg/ml

P--phenytoin(dilantin)

A--acetaminophine

C--cloramphenicol

T--theophylline

Specializes in Medical and general practice now LTC.

a lot of the time the ranges can change from hospital to hospital just did a quick google search and found one that says

0.8 to 2.0 ng/ml so maybe look at an average of 0.5 - 2.0 and should be ok

Thanks for sharing! This post actually saved my butt today, had a practice question involving the correct blood level of Theophylline, never heard of this drug before I read this post but I did remember the correct lab value because of you!!

However I did read today that the normal blood levels of Digoxin are 0.5-2.0 ng/mL, just wondering what the actualy value is.

Also I have seen diarrhea as an early side-effect of digoxin

@sagremus, diarrhea is also a side effect. i used to call dem d 3 brothers. mostly, though not always so, whenever u see nausea n vomitting as a side effect, their brother diarrhea should be around too.........lol
