Aminophylline Usage And Synthesis
  • DescriptionAminophylline is a drug combination consisting of bronchodilator theophylline and ethylenediamine in 2: 1 ratio. It is a kind of non-selective adenosine receptor blocker, histone deacetylase activator and phosphodiesterase inhibition. It is mainly indicated for the treatment of various kinds of lung diseases including asthma, COPD, chronic bronchitis and emphysema. Aminophylline exerts its effect through the component of theophylline in vivo. Theophylline can relax the smooth muscle of the bronchial airways and pulmonary blood vessels. It can competitively inhibits type III and type IV phosphodiesterase (PDE), which breaks down cyclic AMP in smooth muscle cells, possibly leading to bronchodilation. Theophylline also binds to the adenosine A2B receptor to block the adenosine mediated bronchoconstriction. Furthermore, during the inflammatory states, theophylline can activate the histone deacetylase to prevent transcription of inflammatory genes that require the acetylation of histones to initiate the transcription.

  • DescriptionAminophylline is a 2/1 mixture of theophylline and ethylenediamine. It caused contact dermatitis in industrial plants, in pharmacists, and in nurses. Ethylenediamine is the sensitizer, and patch testing is generally positive to both ethylenediamine and aminophylline, but negative to theophylline.
  • Chemical Propertieswhite to slightly yellowish powder
  • OriginatorMemcophylline,Memphis Co.
  • UsesBronchodilatator;Mastocytes degranulation inhibitor
  • UsesAminophylline is a bronchodilator and a non-selective phosphodiesterase (PDE) inhibitor.
  • Manufacturing ProcessA mixture of 198 g (1 mol) theophylline and 60-78 g (0.75-1 mol) ethylenediamine hydrate in 300 g of water was stirred at 50°C and then the mixture was concentrated in vacuo. The product (aminophylline) was separeted by suction filtration. Aminophylline was used as an aqueous solution.

  • Therapeutic FunctionDiuretic, Cardiac stimulant, Smooth muscle relaxant, Vasodilator
  • World Health Organization (WHO)Aminophylline, the ethylenediamine salt of theophylline, was introduced many years ago as a treatment for asthma and is listed in the 8th WHO Model List of Essential Drugs. It has been recognized for some 10 years that aminophylline preparations are not interchangeable because bioavailability can vary considerably. The resulting variability in drug absorption can lead to adverse effects including irritation of the mucosa. Allergic reation can also be an adverse effect of aminophylline. Theophylline functions similarly but is considered less of an irritant.
  • HazardCardiovascular and respiratory collapse.
  • Contact allergensThis drug is a 2:1 mixture of the alkaloid theophylline and ethylenediamine (see below). It caused contact dermatitis in industrial plants, pharmacists, and nurses. Ethylenediamine is the sensitizer and patch testing is generally positive to both ethylenediamine and aminophylline and negative to theophylline.
  • Veterinary Drugs and TreatmentsThe theophyllines are used primarily for their bronchodilatory effects, often in patients with myocardial failure and/or pulmonary edema. While they are still routinely used, the methylxanthines must be used cautiously due to their adverse effects and toxicity.
