AB Methylxanthines  include  caffeine,  theophylline,  theobromine,  and  nicotine.  These  agents  are  plant-derived  alkaloids  with  ubiquitous  use  in  beverages  (caffeine  in  coffee  and  soda),  foods  (theobromine  in  chocolate),  tobacco  products  (nicotine),  and  medications  (theophylline  and  caffeine).  Newer  methylxanthine  derivatives  include  pentoxifylline  (improves  peripheral  blood  flow)  and  doxofylline  (a  bronchodilator).1,2  All  methylxanthines  have  shared  pharmacologic  properties  and  very  similar  pharmacodynamic  effects.
