What is Theophylline used for?
Theophylline is a medication used to treat lung diseases such as asthma and chronic obstructive pulmonary disease (COPD). It works by relaxing the muscles around the airways in the lungs, which helps to open them up and make breathing easier. It is typically taken in oral form.
How does Theophylline work in the body?
Theophylline belongs to a class of drugs called bronchodilators. It acts as a non-selective phosphodiesterase inhibitor and also antagonizes adenosine receptors. By inhibiting phosphodiesterase, it increases intracellular cyclic adenosine monophosphate (cAMP) levels, leading to relaxation of airway smooth muscle. Its antagonism of adenosine receptors also contributes to bronchodilation and may have anti-inflammatory effects.
When does the patent for Theophylline expire?
