Adenosine vs. Theophylline:happy::happy::happy:

 

[waleed]

theoph. blocks adenosine receptors so causing bronchodilation and may cause arrythmia while adenosine is antiarrythmic

 

[ecgram]

yup theophylline is adenosine receptor antagonist

theophylline causes bronchodilation so used in the treatment of asthma , emphysema and chronic bronchitis

it causes ventricular arrythmias where as adenosine is antiarrythmic

Yap !

Both have opposite effects on same Rc.
Adenosine treats arrhythmias but coz asthma.
Theophylline treats asthma but coz arrhythmias.
