Mechanism of Action: How Theophylline Works

Theophylline primarily works by blocking the action of adenosine, a naturally occurring chemical in your body that causes the airways to constrict. By inhibiting adenosine receptors, theophylline promotes bronchodilation – widening your airways and improving airflow to your lungs.

Phosphodiesterase Inhibition

Beyond adenosine antagonism, theophylline also inhibits phosphodiesterase enzymes. This action increases the intracellular concentration of cyclic adenosine monophosphate (cAMP), another crucial molecule involved in smooth muscle relaxation in the lungs. Elevated cAMP further contributes to the bronchodilating effect.

Impact on Inflammatory Response

Importantly, theophylline also demonstrates anti-inflammatory properties. It influences the release of inflammatory mediators, thus reducing airway inflammation. This action contributes to its overall effectiveness in managing respiratory symptoms.

Result: Improved Breathing

The combined effects of adenosine antagonism, phosphodiesterase inhibition, and anti-inflammatory action contribute to improved breathing by reducing airway constriction and inflammation. This translates into easier breathing, reduced coughing and wheezing, and improved lung function.

Common Uses and Indications for Prescription

Theophylline ER 200 mg primarily treats asthma and chronic obstructive pulmonary disease (COPD). It relaxes the muscles of the airways, making it easier to breathe.

Doctors often prescribe it for persistent asthma symptoms not adequately controlled by other medications. This includes wheezing, coughing, and shortness of breath.

Similarly, theophylline helps manage COPD symptoms, improving airflow and reducing breathlessness in patients with this lung condition. However, it’s typically used in conjunction with other COPD treatments.

In some cases, physicians may consider theophylline for treating apnea of prematurity in newborns. Its bronchodilating effects help improve respiratory function in these vulnerable infants.

Remember, theophylline is a prescription medication. Always follow your doctor’s instructions regarding dosage and administration. They will determine the appropriate dose based on your individual health needs.

Dosage and Administration: A Detailed Overview

Theophylline ER 200 mg tablets should be swallowed whole with a glass of water. Avoid crushing or chewing the tablets to maintain the extended-release profile. The specific dosage depends entirely on your individual needs and will be determined by your doctor. Commonly, initial doses range from 100-200 mg once or twice daily. Your physician will adjust your dose based on regular blood tests monitoring theophylline levels. These tests ensure the medication is working effectively without causing adverse effects.

Monitoring Theophylline Levels

Regular blood tests are crucial for safe and effective theophylline treatment.
