Description

Dyphylline is 7-(2,3-dihydroxypropyl)-theophylline, a white, extremely bitter, amorphous powder that is freely soluble in water and soluble in alcohol. Dyphylline is stable in gastrointestinal fluids over a wide range of pH. 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. 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 the bronchial smooth muscle. Dyphylline exerts its bronchodilatory effects directly and, unlike theophylline, is excreted unchanged by the kidneys without being metabolized by the liver. Because of this, dyphylline pharmacokinetics and plasma levels are not influenced by various factors that affect liver function and hepatic enzyme activity, such as smoking, age, congestive heart failure, or concomitant use of drugs which affect liver function.

Sample Use Guides

In Vivo Use Guide

Usual adult dosage: Up to 15 mg/kg every six hours. Dosage should be individually titrated according to the severity of the condition and the response of the patient. Appropriate dosage adjustments should be made in patients with impaired renal function

Route of Administration: Oral

In Vitro Use Guide

Human acute T-lymphocytic leukemia cells CEM-GH (CEM) were cultured with Dyphylline (10 -1000 mkg/mL) for 4 days, and MTT assay measurements are expressed as a viability ratio of drug-treated cells to untreated control cells in each experiment. Dyphylline suppress the growth of human CEM ALL cells in culture with EC50~100 mkg/mL.
