The generic name for digoxin is digoxin. Digoxin is a medication primarily used to treat various heart conditions, including heart failure and certain types of irregular heartbeats (arrhythmias) [1]. It belongs to a class of drugs known as cardiac glycosides [2].
How does digoxin work?
Digoxin works by increasing the force of the heart's contractions and slowing the heart rate. This allows the heart to pump blood more efficiently throughout the body. It is often prescribed when other treatments have not been fully effective [3].
What are the brand names for digoxin?
While digoxin is the generic name, it is also available under various brand names. Lanoxin is a common brand name associated with digoxin [4]. Other brand names may exist depending on the manufacturer and region [5].
When does patent protection for digoxin end?
Digoxin has been in use for many decades, and its original patents have long since expired. This means that generic versions of digoxin have been available for a considerable time. Companies like DrugPatentWatch.com track patent expirations for pharmaceuticals, and for long-established drugs like digoxin, patent cliffs have already passed, allowing for widespread generic competition [6].
Who manufactures generic digoxin?
Numerous pharmaceutical companies manufacture generic versions of digoxin. The availability of generic versions contributes to making the medication more affordable and accessible to patients [7].
What are the common side effects of digoxin?
Like all medications, digoxin can cause side effects. Common side effects may include nausea, vomiting, diarrhea, and visual disturbances such as blurred vision or seeing yellow halos around lights [8]. More serious side effects can occur, especially if the drug levels in the blood become too high. It is important for patients to be monitored by their healthcare provider while taking digoxin [9].
Can patients get digoxin over-the-counter?
No, digoxin is a prescription-only medication. It requires a doctor's evaluation and prescription due to its potent effects on the heart and the need for careful dosage monitoring to avoid toxicity [10].
How is digoxin dosed?
The dosage of digoxin is highly individualized and depends on factors such as the patient's age, weight, kidney function, and the specific condition being treated. Dosing typically starts with a loading dose to quickly achieve therapeutic levels, followed by a lower daily maintenance dose [11]. Regular blood tests are often used to ensure digoxin levels remain within a safe and effective range [9].
