Digoxin ranks as one of the most accessible heart medications. The World Health Organisation's List of Essential Medicines includes this powerful cardiac medication, which highlights its vital importance in healthcare systems worldwide.

Doctors prescribe digoxin to treat mild-to-moderate heart conditions that help patients manage heart failure and chronic atrial fibrillation. The medication works well when patients take it by mouth. However, its effectiveness might decrease if you take it with high-fibre foods. 

This article covers what you should know about digitoxin tablets, from how it works to the right dosing guidelines. Knowing how this medication works, when to take it, and which precautions to follow helps ensure safe and effective treatment of heart conditions.

What is Digoxin

The foxglove plant (Digitalis) gives digoxin, a cardiac glycoside medicine. This remarkable drug continues to play a crucial role in modern cardiology.

• This effective heart medication affects the body in several ways:
• It makes each heartbeat more powerful while slowing down the heart rate
• Blood circulation improves and swelling in the hands and ankles decreases
• The heart contracts more forcefully because it blocks the 'sodium pump' (sodium-potassium ATPase)

The medication comes in several forms:

• Different strength tablets (62.5 mcg, 125 mcg, 250 mcg)
• Oral solution (50 mcg/mL)
• Injectable forms that hospitals usually administer

Digoxin's half-life reaches about 36 hours in patients with normal kidney function. This extends to 3.5-5 days in patients with වකුගඩු අසමත්වීම.

Digoxin Uses

Doctors typically prescribe digoxin to:

• Treat heart failure with diuretics and ACE inhibitors
• Control heart rate in atrial fibrillation cases
• Help stabilise irregular heartbeats (arrhythmias)

How and When to Use Digoxin Tablets

• Take one digoxin tablet daily with water, preferably each morning after breakfast. 
• If you are on it, swallow it whole and not crushed. 
• When your doctor is starting the regimen, they may begin with a higher dose, then adjust to a daily maintenance dose of 125 to 250 micrograms. 

Side Effects of Digoxin Tablets

පොදු අතුරු ආබාධ වන්නේ:

• මෝහනය හෝ සැහැල්ලුබව
• Feeling sick or වමනය
• පාචනය
• Vision changes (blurred or seeing yellow/green tints)
• සමේ රෂ්

පූර්වාරක්ෂාව

• Blood tests help monitor your kidney function and mineral levels. 
• Let your doctor know about your digoxin use before any surgery. 
• Carry medical identification that shows you take this medicine.

How Digoxin Tablets Work

Digoxin makes heart contractions stronger through two main mechanisms. The medicine blocks a pump called Na+/K+ ATPase in heart muscle cells, which increases contractile force. It also stimulates the parasympathetic nervous system and slows electrical signals through your heart's AV node.

Can I Take Digoxin with Other Medicines?

Digoxin interacts with many medicines, including:

• ප්රතිජීවක ඖෂධ 
• දිලීර නාශක
• Arthritis medicines
• ඩයියුරිටික් (ජල පෙති)
• Heart rhythm or blood pressure medications
• HIV ප්රතිකාර

මාත්‍රා තොරතුරු

• The right dose of digoxin plays a vital role in treating heart conditions. Your doctor will calculate your needed dose based on several factors.
• Heart failure and atrial fibrillation patients need different digoxin doses. Doctors prescribe 0.125 to 0.25 mg daily for heart failure patients. 
• Your doctor might start with 0.25 to 0.5 mg and add 0.25 mg doses every 6 hours for atrial fibrillation. The total dose should not go beyond 1.5 mg in 24 hours, and maintenance doses range from 0.0625 to 0.25 mg daily.
• Your ideal dose depends on your body weight, kidney function, and age.
• Blood tests are a key part of your treatment. Your doctor will check digoxin levels 6-12 hours after each dose. Levels between 0.5 and 0.9 ng/mL will give a safe response.
• Your doctor's supervision is essential when changing doses. There's only a small gap between an effective dose and a toxic one.
