Aminophylline is a chemical compound with the formula C16H24N10O4. It is a salt of theophylline, a xanthine alkaloid, and ethylenediamine. Aminophylline is a white, odorless, bitter-tasting powder. It is soluble in water and ethanol.
Theophylline is a stimulant that acts on the central nervous system and the respiratory system. It works by blocking the effects of adenosine, a chemical messenger that causes the muscles in the airways to tighten. When adenosine levels are high, the muscles in the airways contract, making it difficult to breathe. Theophylline blocks the effects of adenosine, which allows the muscles in the airways to relax and open up.
Ethylenediamine is a diamine, which is a chemical compound with two amine groups. It is a colorless, hygroscopic liquid with a strong ammoniacal odor. Ethylenediamine is used in a variety of industrial applications, including the production of textiles, plastics, and pesticides.
Synthesis of aminophylline
Aminophylline can be synthesized by reacting theophylline with ethylenediamine. The reaction is typically carried out in an aqueous solution at an elevated temperature. The aminophylline salt is then precipitated from the solution and dried.
Applications of aminophylline
Aminophylline is a bronchodilator medication used to treat asthma, chronic obstructive pulmonary disease (COPD), and other lung conditions that cause narrowing of the airways. It works by relaxing the muscles in the airways, which makes it easier to breathe.
Aminophylline is also used to treat premature labor. It helps to relax the uterus and prevent early contractions. Aminophylline may also be used to treat other conditions, such as heart failure and sleep apnea, but these uses are less common.
Dosage and administration of aminophylline
Aminophylline is available in tablet, capsule, liquid, and injection form. It is typically taken by mouth, but it can also be injected into a vein or muscle if necessary.
The dosage of aminophylline will vary depending on the individual’s condition and the severity of their symptoms. It is important to follow your doctor’s instructions carefully when taking aminophylline.
Side effects of aminophylline
The most common side effects of aminophylline are mild and go away on their own within a few days. These side effects may include:
- Nausea
- Vomiting

- Headache
- Dizziness
- Shaking
- Anxiety
- Insomnia
More serious side effects of aminophylline can occur if the medication is taken in high doses or if the blood levels of the medication are too high. These side effects may include:
- Seizures
- Heart palpitations
- Irregular heartbeat
- Low blood pressure
- Confusion

Drug interactions
Aminophylline can interact with a number of other medications, including:
- Antibiotics
- Antifungal medications
- Antidepressants
- Beta-blockers
- Diuretics
- Lithium
- Other bronchodilators
- Sedatives
It is important to tell your doctor about all of the medications you are taking before starting aminophylline.
Pregnancy and breastfeeding
