[edit] Properties
It is more soluble in water than theophylline. White or slightly yellowish granules or powder, having a slight ammoniacal odor and a bitter taste. Upon exposure to air, it gradually loses ethylenediamine and absorbs carbon dioxide with the liberation of free theophylline. Its solutions are alkaline. One g dissolves in 25 mL of water to give a clear solution; 1 g dissolved in 5 mL of water crystallizes upon standing, but redissolves when a small amount of ethylenediamine is added. Insoluble in alcohol and in ether.
[edit] Mechanism of action
Aminophylline is less potent and shorter-acting than theophylline. Its most common use is in the treatment of bronchial asthma.
