Dilor-400 Uses, Dosage, Side Effects, Food Interaction and all others data.
Dilor-400 is a theophylline derivative with broncho- and vasodilator properties. It is typically used in the management of asthma, cardiac dyspnea, and bronchitis.
Dilor-400, a xanthine derivative, is a bronchodilator used for relief of acute bronchial asthma and for reversible bronchospasm associated with chronic bronchitis and emphysema. Dilor-400 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.

Uses
Dilor-400 is a theophylline derivative used to treat asthma, bronchospasm, and COPD.
For relief of acute bronchial asthma and for reversible bronchospasm associated with chronic bronchitis and emphysema.
Dilor-400 is also used to associated treatment for these conditions: Bronchial Asthma, Bronchospasm, Cheyne-Stokes Respiration
How Dilor-400 works
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.
Toxicity
LD50=1954 mg/kg (orally in mice)
Dilor-400 Hypertension interaction
[Moderate] Like other methylxanthines, dyphylline at high dosages may be associated with positive inotropic and chronotropic effects on the heart.
Therapy with dyphylline and products containing dyphylline should be administered cautiously in patients with severe cardiac disease, hypertension, hyperthyroidism, or recent myocardial infarction.
The relationship between plasma dyphylline levels and therapeutic as well as toxic effects has not been determined.
