Theophylline and aminophylline are from a group of drugs called xanthine bronchodilators. Other related drugs include theobromine and caffeine. These drugs have a number of pharmacologic effects including relaxation of bronchial smooth muscle, bronchial anti-inflammatory actions, central nervous system stimulation, mild diuresis, increased gastric acid secretion and mild cardiac stimulation. The mechanism of action is through the inhibition of phosphodiesterase which increases cyclic-AMP and endogenous epinephrine. Increased levels of c-AMP may also decrease histamine release. The respiratory anti-inflammatory effects of theophylline may occur at a lower dose than that needed for bronchial smooth muscle relaxation.
Theophylline is well absorbed orally and is metabolized by the liver.
We can let your veterinarian know that you are interested in our compounded Theophylline.
Theophylline is used as a bronchodilator in both dogs and cats to treat bronchoconstriction and inflammation associated with chronic inflammatory lower airway disease and feline asthma. Bronchodilators such as theophylline may be used with corticosteroids, and the use of a bronchodilator may permit a lowering of the dose of the corticosteroids. Theophylline is also used to treat both dogs and cats with collapsing trachea, intrathoracic airway collapse and pulmonary edema.
