What is Aminophylline?

Aminophylline is a 2 to 1 ratio drug combination of theophylline and ethylenediamine. To alleviate symptoms of reversible airway obstruction due to asthma or other chronic lung disorders such as chronic bronchitis and emphysema, it is FDA approved. It is also used in preterm infants to avoid apnea.

Aminophylline Uses

Aminophylline is used to prevent and treat asthma, chronic bronchitis, emphysema, and other lung disorders caused by wheezing, shortness of breath, and trouble breathing. It relaxes and expands air passages, making breathing easier in the lungs.

How to use this drug

Often this drug is prescribed for other uses; request more details from your doctor or pharmacist.

Aminophylline comes as a mouth-taking tablet and syrup and a rectally inserted suppository. It is normally administered every 6, 8, or 12 hours. Carefully follow the instructions on the prescription label and ask your doctor or pharmacist to clarify any aspect that you do not understand. Take exactly as instructed, aminophylline. Do not take or take more or less of it more often than recommended by your physician.

  • Take tablets or an oral liquid on an empty stomach with a full glass of water, at least 1 hour before or 2 hours after a meal. Do not chew the long-acting tablets or crush them; swallow them whole.
  • Aminophylline controls but does not cure, the effects of asthma and other lung diseases. Even if you are not well, continue taking aminophylline. Without consulting your doctor, do not quit taking aminophylline.

Follow these steps in order to implant a rectal suppository:

  • Get the wrapping off
  • Dip the suppository tip in the water
  • Lie down and bring your right knee to your chest on your left side. (A person who is left-handed should lie on the right side and lift his left knee.).
  • Insert the suppository into the rectum using your finger, roughly 1/2 to 1 inch (1.25 to 2.5 centimeters) in infants and children, and 1 inch (2.5 centimeters) in adults. For a couple of moments, keep it in place.
  • Stand up after 15 minutes, roughly. Carefully wash your hands and resume your daily activities.
