Key takeaways
Digitalis glycosides as cardiotonics: a cartoon on how digoxin strengthens heart contraction in heart failure and why its narrow therapeutic index matters.
Digitalis:
Digitalis is a great great plant 🙂 ! , it’s leaves are rich in Glycosides which are very popular in the treatment of many cardiac diseases especially ” Digoxin glycoside ” 🙂
Digitalis is sub-classified into many species ” e.g: Digitalis Lanata ”
Let’s have a look on our today’s toon :whistle:
Mr heart has been taking digitalis with optimum dosage,” do you know the digitalis standard regimen 😉 ?”
as you see Mr Heart looks in Great shape :heart: , pretty muscular 😎 … thanks to digitalis content of cardiac glycosides :happy:
these Glycosides strengthen the muscles of the heart ” +ve inotropic effect “ enabling the heart to pump blood more efficiently
that’s why they are called ” Cardiotonic “
Cardio = Heart
Tonic = increase the muscle tone
.

Mmmm …
that’s it about Digitalis action .. but wait ! , take a look again to Our toon 🙂
Noticed anything weird :blink: ?
Yeah , Mr heart is Sleepy :sleeping: … i’ll tell you why 🙂
Digoxin is awesome in the treatment of CHF ” congestive hear faliure ” , but nothing is perfect in this life :ermm:
Digoxin has a very narrow therapeutic index :ermm: ” tiny difference between therapeutic dose & toxic dose “ :unsure:
+ plus , it has long half life :ermm: ” slowly eliminated out of the body “ :unsure:
So , if Digoxin doses aren’t monitored & adjusted properly for each patient .. there would be a high risk of toxicity :dizzy:
Digitalis toxicity can lead to life threatening Heart Block “that’s the sleepy heart in the toon 😉 “
Do you know what is the Antidote for Digitalis Toxicity?
“Digibind“ is the antidote for life-threatening digoxin or digitoxin toxicity ,
it’s an anti-digoxin immunotherapy of purified Fab fragments extracted from animals ” e.g: ovine “
it’s administered intravenously in saline solution over 30 to 60 minutes [/tip]
it’s also helpful to assess the patient for the most common early indicators of toxicity which are usually GI -related
Common Gastrointestinal symptoms include :
- Abdominal pain
- Anorexia
- Diarrhea
- Nausea
- Vomiting
Early management & Dose adjustment would fully prevent the development of sever digitalis toxicity 🙂
:heart: God bless your hearts and souls :happy: :heart:
further information about Digitalis glycosides ” Digoxin \ Digitoxin ” will be discussed later 🙂
