                  Function

 

 

Function

Dyphylline theophylline smooth muscle relaxant, has the effect of dilating bronchial and coronary arteries, and has a diuretic effect. Stable in gastric juice. The antiasthmatic effect is similar to aminophylline, especially for tachycardia. Applicable to bronchial asthma, wheezing bronchitis and other symptoms of wheezing.

 

Application

Dyphylline is an inhibitor to phosphodiesterase. It is used in the therapy of bronchial asthma, gasping bronchitis and gasping from cardiogenic pulmonary edema. It can soothe the symptom of gasping through loosening bronchial smooth muscle, increasing cardiac blood output, expanding kidney arteriole, increasing glomerulus filtration and renal blood flow, inhibiting distal end renal tubule's reabsorption of sodion and chloridion, and increasing contractility of hanging skeletal muscle. Its action of expanding bronchus is only one tenth of that of aminophylline. It can easily be absorbed orally, metabolize to derivants of theophylline in vivo, and are excreted with urine.
