Aminophylline is a bronchodilator medication that works by relaxing the muscles in the airways. This makes it easier to breathe, especially for people with asthma or other lung conditions that cause narrowing of the airways.
Aminophylline 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. Aminophylline blocks the effects of adenosine, which allows the muscles in the airways to relax and open up.
In addition to its bronchodilator effects, aminophylline also has a number of other effects on the body, including:
- Stimulating the central nervous system: Aminophylline can cause increased alertness, wakefulness, and restlessness.
- Increasing heart rate and blood pressure: Aminophylline can cause the heart rate to increase and blood pressure to rise.
- Relaxing the smooth muscles in the blood vessels: Aminophylline can cause the smooth muscles in the blood vessels to relax, which can lead to increased blood flow.
- Increasing the production of urine: Aminophylline can cause the kidneys to produce more urine.
These other effects of aminophylline can be beneficial in some cases, but they can also cause side effects, such as anxiety, insomnia, palpitations, and headache.
