Neophylline: Full Drug Profile

Neophylline - General Information

A theophylline derivative with broncho- and vasodilator properties. It is used in the treatment of asthma, cardiac dyspnea, and bronchitis. [PubChem]

Pharmacology of Neophylline

Neophylline, a xanthine derivative, is a bronchodilator used for relief of acute bronchial asthma and for reversible bronchospasm associated with chronic bronchitis and emphysema. Neophylline 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.

Neophylline for patients

Neophylline Interactions

Synergism between xanthine bronchodilators (e.g., theophylline), ephedrine, and other sympathomimetic bronchodilators has been reported. This should be considered whenever these agents are prescribed concomitantly.

Concurrent administration of dyphylline and probenecid, which competes for tubular secretion, has been shown to increase the plasma half-life of dyphylline.

Neophylline Contraindications

Hypersensitivity to dyphylline or related xanthine compounds.

Neophylline Indication

For relief of acute bronchial asthma and for reversible bronchospasm associated with chronic bronchitis and emphysema.

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.
