Identification
- Name
- Aminophylline
- Accession Number
- DB01223
- Description
Aminophylline is a drug combination that contains theophylline and ethylenediamine in a 2:1 ratio. Once in the body, theophylline is released and acts as a phosphodiesterase inhibitor, adenosine receptor blocker, and histone deacetylase activator. Similar to other theophyllines, aminophylline is indicated for the treatment of lung diseases such as asthma, chronic bronchitis, and COPD. The majority of aminophylline medications are discontinued and the remaining medications on the market are in short supply.

Learn More- Pharmacodynamics
Aminophylline is the ethylenediamine salt of theophylline. Theophylline stimulates the CNS, skeletal muscles, and cardiac muscle. It relaxes certain smooth muscles in the bronchi, produces diuresis, and causes an increase in gastric secretion.
- Mechanism of action
Aminophylline is the ethylenediamine salt of theophylline. After ingestion, theophylline is released from aminophylline, and theophylline relaxes the smooth muscle of the bronchial airways and pulmonary blood vessels and reduces airway responsiveness to histamine, methacholine, adenosine, and allergen. Theophylline competitively inhibits type III and type IV phosphodiesterase (PDE), the enzyme responsible for breaking down cyclic AMP in smooth muscle cells, possibly resulting in bronchodilation. Theophylline also binds to the adenosine A2B receptor and blocks adenosine mediated bronchoconstriction. In inflammatory states, theophylline activates histone deacetylase to prevent transcription of inflammatory genes that require the acetylation of histones for transcription to begin.

- Food Interactions
- Administer vitamin supplements. Aminophylline may reduce Vitamin B6 levels as an adverse effect. Consider supplementation.
- Avoid excessive or chronic alcohol consumption. Ingesting a large amount of alcohol may reduce aminophylline clearance, therefore increasing its serum concentration.
- Exercise caution with grapefruit products. Grapefruit inhibits CYP3A4 metabolism, which may increase the serum concentration of aminophylline.
- Exercise caution with St. John's Wort. This herb induces the CYP3A4 metabolism of aminophylline. Therefore it may reduce the serum concentration and effectiveness of aminophylline.
- Limit caffeine intake. Excessive caffeine intake with aminophylline may exacerbate caffiene-like side effects such as nausea, nervousness, irritability, insomnia and tremors.
- Take with food. This may reduce gastric irritation. Aminophylline absorption is slower when taken with food.
