Theodur Information:
Buy Theodur
Theodur (Theophylline SR 12 HR) is used alone or with other medications to treat bronchospasm caused by chronic respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). Its active ingredient is theophylline, a bronchodilator in the methylxanthine class of drugs. Theophylline works by inhibiting the enzyme phosphodiesterase, increasing cyclic AMP (cAMP) levels, which helps relax bronchial smooth muscles and dilate the airways. This improves airflow, reduces wheezing, and eases shortness of breath.

Clinical studies have demonstrated that Theodur (theophylline SR 12 HR) effectively improves bronchospasm symptoms in patients with asthma and COPD. It provides sustained bronchodilation, with most patients experiencing improved symptoms and better control of their condition. However, it has a narrow therapeutic window, so regular monitoring of serum theophylline levels is crucial to avoid toxicity.

Theodur is a sustained-release (SR) formulation designed to release the drug over 12 hours, allowing for twice-daily dosing and providing long-lasting symptom relief. The dosage may be different in children. Consult your doctor for the appropriate dosage of this medication for you.
