Abbreviated New Drug Application
ELIXOPHYLLIN- THEOPHYLLINE ANHYDROUS LIQUID NOSTRUM LABORATORIES, INC. ---------- ELIXOPHYLLIN ELIXIR (THEOPHYLLINE ORAL SOLUTION, USP) (BRAND OF THEOPHYLLINE ANHYDROUS) RX ONLY DESCRIPTION Theophylline is structurally classified as a methylxanthine. It occurs as a white, odorless, crystalline powder with a bitter taste. Anhydrous theophylline has the chemical name 1H-Purine- 2,6-dione, 3,7- dihydro-1,3-dimethyl-, and is represented by the following structural formula: The molecular formula of anhydrous theophylline is C7H8N4O2 with a molecular weight of 180.17. ELIXOPHYLLIN Elixir (Theophylline Oral Solution, USP) is available as a liquid intended for oral administration, containing 80 mg of theophylline anhydrous and 20% alcohol in each 15 mL (tablespoonful). ELIXOPHYLLIN Elixir (Theophylline Oral Solution, USP) also contains the following inactive ingredients: anhydrous citric acid, glycerin, saccharin sodium, artificial tutti fruiti flavor #051880A, FD&C red #40 and purified water. ELIXOPHYLLIN Elixir (Theophylline Oral Solution, USP) has a pH of 3.0-4.0. CLINICAL PHARMACOLOGY MECHANISM OF ACTION: Theophylline has two distinct actions in the airways of patients with reversible obstruction; smooth muscle relaxation (i.e., bronchodilation) and suppression of the response of the airways to stimuli (i.e., non-bronchodilator prophylactic effects). While the mechanisms of action of theophylline are not known with certainty, studies in animals suggest that bronchodilatation is mediated by the inhibition of two isozymes of phosphodiesterase (PDE III and, to a lesser extent, PDE IV) while non-bronchodilator prophylactic actions are probably mediated through one or more different molecular mechanisms, that do not involve inhibition of PDE III or antagonism of adenosine receptors. Some of the adverse effects associated with theophylline appear to be mediated by inhibition of PDE III (e.g., hypotension, tachycardia, headache, and emesis) and adenosine receptor antagonism (e.g., alterations in cerebral blood flow).
