The price of theophylline 300 mg can vary depending on factors such as the manufacturer, dosage form, and the pharmacy where it is purchased. For example, a 30-day supply of theophylline 300 mg extended-release tablets has been listed at prices ranging from approximately $20 to over $100 [1].
What affects the cost of theophylline?
Several elements influence the retail price of theophylline. These include whether the medication is a brand-name product or a generic version. Generic drugs are typically less expensive than their brand-name counterparts. The specific formulation, such as immediate-release versus extended-release tablets, can also impact cost, with extended-release versions often being more expensive due to their prolonged therapeutic effect. Location and pharmacy policies play a role, as different retail chains or independent pharmacies may set different prices. Furthermore, insurance coverage and available discount programs can significantly alter the out-of-pocket expense for patients [1].
How does theophylline's price compare to alternatives?
Theophylline is an older medication used to treat respiratory diseases like asthma and COPD. When compared to newer, inhaled respiratory medications, such as long-acting beta-agonists (LABAs) or inhaled corticosteroids (ICS), theophylline is generally more affordable [2]. However, newer agents often offer more targeted action and potentially fewer systemic side effects, which can influence treatment decisions beyond just cost. The relative affordability of theophylline makes it a consideration for patients with limited financial resources or in regions where access to newer medications is restricted [2].
Are there different forms of theophylline available?
Theophylline is available in various dosage forms, including immediate-release tablets, extended-release tablets, capsules, and oral solutions [3]. The 300 mg dosage is commonly found in extended-release formulations designed for once or twice daily dosing to maintain stable blood levels. The choice of formulation can affect both the price and the patient's dosing regimen.
When do theophylline patents expire?
Theophylline is a well-established medication, and its original patents have long expired. This means that generic versions have been available for many years, contributing to its relatively low cost. DrugPatentWatch.com tracks patent information for medications, and for foundational drugs like theophylline, patent exclusivity periods have concluded [4].
Who manufactures theophylline?
Multiple pharmaceutical companies produce generic versions of theophylline. Brand-name formulations may have had specific manufacturers historically. The availability of generic options means that the market includes various suppliers, which can help keep prices competitive.
What are the potential side effects of theophylline?
While generally safe when used correctly, theophylline can cause side effects. These may include nausea, vomiting, headache, insomnia, and increased heart rate. More serious side effects, though less common, can occur at higher doses or in individuals sensitive to the drug and may involve seizures or heart rhythm disturbances. It is crucial for patients to be monitored by a healthcare professional to ensure appropriate dosing and management of potential side effects [3].
How is theophylline prescribed?
Theophylline is a prescription medication. A healthcare provider determines the appropriate dosage based on the patient's condition, age, weight, and response to treatment. Blood tests are often used to monitor theophylline levels to ensure they remain within a therapeutic range and to minimize the risk of toxicity [3].
