How do xanthine derivatives work?
Xanthine derivatives are medications used to treat bronchospasm caused by lung conditions such as asthma. Xanthine is a naturally occurring compound in the human body and is also found in plant products such as tea, coffee, and cocoa beans.
Xanthine derivatives are a group of alkaloids that work as mild stimulants and bronchodilators. Xanthine derivatives ease symptoms of bronchospasm and make breathing easier by relaxing the smooth muscles of the respiratory tract and reducing the airway's hypersensitive response to stimuli.
Xanthine derivatives increase the cellular levels of signaling molecules known as cyclic adenosine monophosphate (cAMP) by inhibiting the activity of phosphodiesterase, an enzyme that regulates cAMP levels. An increase in tissue concentration of cAMP results in bronchial smooth muscle relaxation and bronchodilation.
