This medication acts as a bronchodilator, offering relief to individuals struggling with breathing difficulties. Beyond its primary application in respiratory disorders, Theophylline also exhibits effects on the heart and central nervous system, making it a versatile medication in certain medical scenarios.
Regulatory agencies, such as the FDA or EMA, have established guidelines outlining the testing and approval processes for light-sensitive drugs. These guidelines require comprehensive stability studies that assess how the API stands up against light exposure over time. Such studies not only confirm the drug's shelf life but also assist in determining optimal storage conditions and packaging requirements.
Venous Ulcers: Pentoxifylline may also be used in the management of venous ulcers, which are open sores that develop on the legs or feet due to impaired venous circulation. By enhancing blood flow and tissue oxygenation, pentoxifylline aids in wound healing and promotes the closure of venous ulcers.
