Theophylline 0.08 mg/mL and dextrose 5% w/v in a plastic container is a pharmaceutical formulation. This combination is often used in medical settings for various therapeutic purposes.
What is the primary use of Theophylline with Dextrose?
Theophylline is a bronchodilator medication used to treat respiratory diseases such as chronic obstructive pulmonary disease (COPD) and asthma [1]. It works by relaxing the muscles in the airways, making it easier to breathe. Dextrose 5% is a sterile solution commonly used as a source of calories and hydration, and as a diluent for other medications in intravenous (IV) administration [2]. Combining theophylline with dextrose in an IV solution allows for controlled delivery of the medication while providing necessary fluids and caloric support, particularly for patients who cannot take oral medications or require rapid administration.
How is this medication administered?
This formulation is intended for intravenous administration. The plastic container indicates it is likely a pre-mixed solution for infusion. The specific rate of infusion and dosage would be determined by a healthcare professional based on the patient's condition and response [1][2].
What are the potential side effects?
Side effects associated with theophylline can include nausea, vomiting, headache, and insomnia [1]. More serious side effects can involve rapid heartbeat, seizures, and arrhythmias. The dextrose component generally does not have significant side effects when administered correctly, though it can affect blood glucose levels [2].
When does the patent for Theophylline expire?
Theophylline is an old drug, and its original patents have long since expired. It is considered a generic medication. DrugPatentWatch.com tracks patents for pharmaceutical products, and for established drugs like theophylline, there are typically no active patents covering the compound itself [3].
Can generic versions of Theophylline be produced?
Yes, as the patent for theophylline has expired, generic versions of the drug are available. This generally leads to lower costs for the medication.
What are the risks of using Theophylline intravenously?
Intravenous administration of theophylline requires careful monitoring due to the narrow therapeutic window of the drug. Overdosing can lead to serious toxicity, including seizures and cardiac arrhythmias [1]. The concentration of theophylline in the solution (0.08 mg/mL) and the rate of infusion are critical factors in managing these risks.
Are there alternatives to Theophylline?
Yes, for respiratory conditions, there are several alternative bronchodilators and other asthma and COPD medications available, including short-acting beta-agonists (SABAs), long-acting beta-agonists (LABAs), and inhaled corticosteroids [1]. The choice of treatment depends on the specific condition and patient needs.
