Description
Aminophylline Anhydrous Product Overview
Aminophylline is a 2:1 complex of theophylline with ethylenediamine. It is a white or slightly yellowish granular powder with a slight ammonia-like odor. The ethylenediamine makes theophylline far more water-soluble, which allows injectable solutions. Anhydrous aminophylline contains about 84–87% theophylline.
Pharmaceutical companies use it in injections, tablets and modified-release tablets in the methylxanthine bronchodilator class. Veterinary producers use it in some products for animals. Theophylline is chemically related to Caffeine anhydrous, and the antihistamine Dimenhydrinate also contains a theophylline derivative.
Aminophylline absorbs carbon dioxide from the air and slowly releases free theophylline, so it must be stored in tightly sealed containers. Zyntex supplies it only to licensed pharmaceutical companies.
