Astrophylline, also known as aminophylline, is a medication derived from theophylline, a bronchodilator used to treat respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). It is a combination of theophylline and ethylenediamine, which enhances the solubility and absorption of theophylline, allowing for faster action and more effective relief of symptoms. Astrophylline works by relaxing the muscles in the airways, reducing inflammation, and increasing the efficiency of breathing. It is available in various forms, including tablets, injections, and oral solutions, and is typically prescribed to patients who require rapid relief or cannot tolerate other forms of theophylline.
