The price of theophylline can vary depending on factors such as the dosage, formulation (e.g., immediate-release, sustained-release), and the specific manufacturer. As a generic medication, theophylline is generally more affordable than many brand-name drugs.
What factors influence the cost of theophylline?
The cost of theophylline can be influenced by several elements:
* Dosage and Strength: Higher milligram strengths or specific dosages may have different price points.
* Formulation: Immediate-release tablets, extended-release capsules, and oral solutions can be priced differently. Extended-release formulations, designed to provide a more consistent drug level over time, might carry a slightly higher cost.
* Manufacturer: As a generic drug, multiple companies produce theophylline, and prices can differ between them.
* Pharmacy and Location: Retail pharmacy prices can vary significantly based on the pharmacy chain, independent pharmacy, or whether it is purchased through a mail-order service. Geographic location can also play a role.
* Insurance Coverage: The patient's health insurance plan will significantly impact out-of-pocket costs through copayments, deductibles, or coinsurance.
* Generic vs. Brand Name: While theophylline is widely available as a generic, if any brand-name versions exist or were historically prominent, their pricing would typically be higher than generics.

To find current pricing information for theophylline, consumers can utilize online pharmacy price comparison tools. Websites like DrugPatentWatch.com offer resources for comparing drug prices [1]. Additionally, checking the websites of major pharmacy chains or contacting local pharmacies directly can provide specific cost details.
What is theophylline used for?
Theophylline is a bronchodilator medication used to treat respiratory diseases such as chronic obstructive pulmonary disease (COPD) and asthma [2]. It works by relaxing the muscles in the airways, making it easier to breathe.
Are there alternatives to theophylline?
Yes, there are several alternative medications for managing asthma and COPD. These include inhaled corticosteroids, long-acting beta-agonists (LABAs), short-acting beta-agonists (SABAs), anticholinergics, and leukotriene modifiers [3]. The choice of treatment depends on the severity and type of respiratory condition, as well as individual patient factors.
How is theophylline administered?
Theophylline is typically administered orally, in tablet, capsule, or liquid form [2]. It is also available for intravenous use in emergency situations.
What are the potential side effects of theophylline?
Common side effects of theophylline can include nausea, vomiting, headache, insomnia, and irritability [2]. More serious side effects, particularly at higher doses, can involve rapid heart rate, irregular heartbeats, seizures, and difficulty breathing.
Does theophylline have patent protection?
Theophylline is an older medication, and its original patents have long expired. This has allowed for the widespread availability of generic versions from multiple manufacturers. Information on the patent status of various drugs, including older ones like theophylline, can be found on resources like DrugPatentWatch.com [1].
How does theophylline compare to other bronchodilators?
Theophylline is a xanthine derivative bronchodilator. It differs from other classes of bronchodilators, such as beta-agonists (e.g., albuterol) and anticholinergics (e.g., ipratropium), in its mechanism of action and its therapeutic window. While it can be effective, its use is often limited by a narrow therapeutic index, meaning the dose that is effective is close to the dose that causes toxicity. This requires careful monitoring of blood levels [3].
What are the risks of taking theophylline?
The primary risk associated with theophylline is its narrow therapeutic index. Overdosing can lead to significant toxicity, including severe cardiovascular and central nervous system effects [2]. Drug interactions are also a concern, as many medications can affect the metabolism of theophylline, increasing the risk of toxicity.
When was theophylline developed?
Theophylline has been used medically for many decades. Its origins trace back to the late 19th and early 20th centuries, with its use as a bronchodilator becoming more established in the mid-20th century. As an old drug, its patents have long since expired.
