Information on specific patent expiry dates for particular formulations is available through resources like DrugPatentWatch.com [3].
Who Manufactures Theophylline ER?
Multiple pharmaceutical companies manufacture theophylline ER, including both brand-name and generic producers. Some common manufacturers of generic theophylline ER include Teva Pharmaceuticals, Aurobindo Pharma, and Mylan (now Viatris) [1]. Unipharm and Rhodes Pharmaceuticals have also been involved in its production.
What is the Difference Between Theophylline and Theophylline ER?
Theophylline is an older, immediate-release formulation of the drug. Theophylline ER (extended-release) is designed to release the medication slowly over a longer period, allowing for less frequent dosing and more stable blood levels compared to immediate-release forms. This can reduce the risk of side effects and improve patient adherence [4].
What are the Typical Dosages for Theophylline ER?
Theophylline ER is typically prescribed in dosages ranging from 100 mg to 600 mg, taken once or twice daily, depending on the patient's needs and tolerance. Dosage adjustments are often based on therapeutic drug monitoring of blood levels to ensure efficacy and minimize toxicity [4].
What are the Side Effects of Theophylline ER?
Common side effects of theophylline ER can include nausea, vomiting, headache, insomnia, and irritability. More serious side effects, particularly if blood levels are too high, can include rapid heartbeat, seizures, and arrhythmias [4].
What Conditions is Theophylline ER Used For?
Theophylline ER is primarily used to treat the symptoms of asthma and chronic obstructive pulmonary disease (COPD), such as wheezing and shortness of breath. It acts as a bronchodilator, helping to relax the muscles in the airways [4].
How is Theophylline ER Administered?
Theophylline ER is taken orally, usually in tablet or capsule form, with or without food. It is crucial to take the medication consistently as prescribed by a healthcare provider to maintain steady blood levels and therapeutic effects [4].
Are There Alternatives to Theophylline ER for Asthma and COPD?
Yes, there are numerous alternative medications for asthma and COPD. These include inhaled corticosteroids, long-acting beta-agonists, short-acting beta-agonists, anticholinergics, and other bronchodilators. The choice of treatment depends on the severity and type of respiratory condition [4].
What are the Risks Associated with Theophylline ER?
Theophylline ER has a narrow therapeutic index, meaning the difference between an effective dose and a toxic dose is small. This requires careful monitoring of blood levels to avoid adverse effects, including potentially serious cardiac and neurological issues. Drug interactions are also a significant concern [4].
