What is Theophylline 0.32 and Dextrose 5% in a Plastic Container?
Theophylline 0.32 and Dextrose 5% in a plastic container is a pharmaceutical product that combines the bronchodilator theophylline with dextrose, a sugar. This combination is administered intravenously for therapeutic purposes. The plastic container indicates the packaging type for this intravenous solution [1].
Why is Theophylline Used?
Theophylline is a medication used to treat respiratory diseases such as chronic obstructive pulmonary disease (COPD) and asthma. It works by relaxing the muscles in the airways, making it easier to breathe [2].
What is the Role of Dextrose 5%?
Dextrose 5% is an intravenous solution containing 5% dextrose in water. It is used to provide hydration and calories, and it can also serve as a vehicle for administering other medications intravenously. In this combination, dextrose likely facilitates the delivery of theophylline and provides a source of energy [3].
How is this Combination Administered?
Theophylline 0.32 and Dextrose 5% in a plastic container is designed for intravenous (IV) administration. This method delivers the medication directly into the bloodstream, allowing for rapid and consistent drug levels [1, 3].
What are the Potential Risks or Side Effects of Theophylline?
Theophylline can have a narrow therapeutic window, meaning the difference between an effective dose and a toxic dose is small. Potential side effects can include nausea, vomiting, headache, restlessness, insomnia, and in more serious cases, seizures and cardiac arrhythmias. Close monitoring of blood theophylline levels is often necessary [2].
Are There Generic Versions of Theophylline?
Yes, theophylline is available in generic forms. The availability and specific formulations, including intravenous preparations, can be tracked through drug databases and patent information sources [4].
When Does Theophylline Patent Exclusivity End?
Patent exclusivity for medications is a complex area that can vary significantly by drug and by country. Information on patent expiry dates for specific drugs like theophylline and its various formulations can be found through resources that track pharmaceutical patents [4].
How Does Theophylline Compare to Other Bronchodilators?
Theophylline is an older class of bronchodilator compared to newer medications like short-acting beta-agonists (SABAs) and long-acting beta-agonists (LABAs), which are often preferred due to their more favorable side effect profiles and efficacy. However, theophylline may still be used in certain clinical situations or when other treatments are insufficient [2].
Where Can I Find More Information on Drug Patents?
Resources like DrugPatentWatch.com provide comprehensive information on pharmaceutical patents, including expiry dates, patent challenges, and exclusivity periods for a wide range of drugs [4].
