Dyphylline, a xanthine derivative, is a bronchodilator used for relief of acute bronchial asthma and for reversible bronchospasm associated with chronic bronchitis and emphysema. Dyphylline is a xanthine derivative with pharmacologic actions similar to theophylline and other members of this class of drugs. Its primary action is that of bronchodilation, but it also exhibits peripheral vasodilatory and other smooth muscle relaxant activity to a lesser degree.
- Mechanism of action
The bronchodilatory action of dyphylline, as with other xanthines, is thought to be mediated through competitive inhibition of phosphodiesterase with a resulting increase in cyclic AMP producing relaxation of bronchial smooth muscle as well as antagonism of adenosine receptors.

- Route of elimination
Dyphylline exerts its bronchodilatory effects directly and, unlike theophylline, is excreted unchanged by the kidneys without being metabolized by the liver. Approximately 88% of a single oral dose can be recovered from the urine unchanged.

Drug Interaction Integrate drug-drug
interactions in your software1,2-Benzodiazepine The therapeutic efficacy of 1,2-Benzodiazepine can be decreased when used in combination with Dyphylline. Abacavir Dyphylline may decrease the excretion rate of Abacavir which could result in a higher serum level. Abiraterone The serum concentration of Dyphylline can be increased when it is combined with Abiraterone. Acebutolol The risk or severity of adverse effects can be increased when Acebutolol is combined with Dyphylline. Aceclofenac Aceclofenac may decrease the excretion rate of Dyphylline which could result in a higher serum level. Acemetacin Acemetacin may decrease the excretion rate of Dyphylline which could result in a higher serum level. Acetaminophen Acetaminophen may decrease the excretion rate of Dyphylline which could result in a higher serum level. Acetazolamide Acetazolamide may increase the excretion rate of Dyphylline which could result in a lower serum level and potentially a reduction in efficacy. Acetylsalicylic acid Acetylsalicylic acid may decrease the excretion rate of Dyphylline which could result in a higher serum level. Aclidinium Dyphylline may decrease the excretion rate of Aclidinium which could result in a higher serum level.
