Question 1

What is Theophylline?

Accepted Answer

Theophylline is a member of the methylxanthine class of medications. It functions as a bronchodilator, which means it works by relaxing the smooth muscles surrounding the bronchial tubes in the lungs.

This action helps to open the air passages and increase the flow of air through the respiratory system.

Question 2

What is Theophylline used for?

Accepted Answer

Theophylline is used to treat asthma and chronic obstructive pulmonary disease .

Question 3

How does Theophylline work?

Accepted Answer

How Theophylline Works

Theophylline belongs to a group of medicines known as bronchodilators. It works primarily by relaxing the smooth muscles that surround the bronchial tubes, which are the air passages in the lungs. When these muscles relax, the airways open wider, allowing more air to flow in and out of the lungs.

By opening the airways, theophylline helps to relieve and prevent symptoms such as:

Wheezing

Shortness of breath

Coughing

Chest tightness

In addition to relaxing airway muscles, theophylline may also help by:

Decreasing the lungs' inflammatory response to irritants or triggers.

Increasing the strength of the diaphragm, which is the primary muscle used for breathing.

While the exact cellular process is not fully understood, evidence suggests the medication works by blocking certain enzymes and chemical receptors in the body that otherwise cause the airways to tighten and constrict.

Question 7

What drug class is Theophylline?

Accepted Answer

Theophylline belongs to the methylxanthine bronchodilator drug class.

Question 8

What is the dosage of Theophylline and how do I take it?

Accepted Answer

General Administration

Theophylline is most commonly taken by mouth as a liquid, immediate-release tablet, or extended-release tablet or capsule. In clinical settings, it may also be administered through an intravenous infusion. It is important to take this medication at the same time each day to keep a steady amount of the drug in the body.

How to Take Oral Forms

Extended-release tablets and capsules: These should generally be swallowed whole. Do not crush, chew, or break them unless specifically instructed by a healthcare provider, as doing so can release too much medicine at once. Some specific brands of capsules may be opened and the contents sprinkled on a small amount of soft food, but the beads must not be chewed.

Liquid forms: Always use a marked measuring spoon, oral syringe, or medicine cup to ensure the correct amount. Do not use a regular household spoon.

Food consistency: Some versions of theophylline should be taken on an empty stomach, while others may be taken with food. It is vital to be consistent; if you start taking it with food, continue to take it with food every time. High-fat meals can significantly change how some extended-release products are absorbed.

Missed Dose

If a dose is missed, take it as soon as you remember. If it is almost time for the next scheduled dose, skip the missed dose and continue with the regular schedule. Do not take two doses at once or take extra medicine to make up for a missed one.

Monitoring and Adjustments

Because the amount of theophylline needed can vary based on age, weight, smoking status, and other health conditions, healthcare providers will perform regular blood tests. These tests help ensure the dosage is within a safe and effective range. Do not change the dose or stop taking the medication without consulting a doctor, even if symptoms improve.

Question 9

Is Theophylline safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

Theophylline crosses the placenta and enters the fetal circulation. It is generally recommended for use during pregnancy only when clearly needed. Because the way the body processes theophylline can change during pregnancy, healthcare providers often monitor blood levels more frequently to ensure the dosage remains within a safe and effective range.

If the mother has high levels of theophylline in her blood at the time of delivery, the newborn may experience symptoms of theophylline toxicity. These symptoms can include:

Irritability

Rapid heartbeat

Vomiting

Breastfeeding

Theophylline is excreted into breast milk and may cause side effects in a nursing infant. Healthcare providers typically consider the importance of the drug to the mother when deciding whether she should continue breastfeeding while taking this medication.

Infants who are exposed to theophylline through breast milk should be monitored for signs of toxicity, such as:

Irritability or unusual fussiness

Difficulty sleeping

Increased activity or restlessness

Question 10

What forms and strengths does Theophylline come in?

Accepted Answer

Oral Forms

Theophylline is most commonly taken by mouth. These forms include:

Immediate-release tablets: These release the medication into the body shortly after being swallowed.

Extended-release tablets: These are designed to release the medication slowly over a period of time.

Extended-release capsules: These capsules provide a slow release of the drug into the system.

Oral solution: A liquid form of the medication, which may be used for patients who have difficulty swallowing pills.

Injectable Forms

For more severe symptoms or when oral medication cannot be taken, theophylline is available as an injection:

Intravenous (IV) infusion: This form is administered directly into a vein by a healthcare professional, typically in a hospital setting.

Combination Products

Theophylline may also be found in combination with other active ingredients, such as guaifenesin, in oral liquid or tablet forms.

Question 11

What is the FDA approval status of Theophylline?

Accepted Answer

FDA Approval Status

Theophylline is approved by the U.S. Food and Drug Administration (FDA) for the treatment of the symptoms of reversible airway obstruction associated with chronic asthma and other chronic lung diseases, such as emphysema and chronic bronchitis.

Regulatory Considerations

Theophylline is available only with a prescription from a healthcare provider. It is not classified as a controlled substance. Because the drug has a narrow therapeutic index—meaning the margin between a therapeutic dose and a toxic dose is small—FDA-approved labeling includes specific guidance on monitoring blood levels to ensure safety and effectiveness.

Boxed Warnings and REMS

There are currently no FDA boxed warnings or Risk Evaluation and Mitigation Strategies (REMS) programs required for theophylline. However, healthcare providers must carefully manage dosages based on individual patient factors, such as age, weight, and concurrent medications, to prevent toxicity.

Question 12

What should I know about Theophylline and alcohol?

Accepted Answer

Alcohol and Theophylline

Consuming alcohol while taking theophylline can change how your body breaks down the medication. Alcohol may decrease the clearance of theophylline, which means the drug stays in your system longer and can reach higher levels in your blood.

When theophylline levels become too high, it increases the risk of experiencing side effects or toxicity. Potential symptoms of high theophylline levels include:

Severe nausea or vomiting

Rapid or irregular heartbeat

Tremors or shakiness

Difficulty sleeping

Seizures

It is best to discuss your alcohol use with your healthcare provider. They can provide guidance on whether you should limit or completely avoid alcohol while being treated with theophylline.
