Digitek

Properties

This medicine contains digoxin as active ingredient. It belongs to the group of cardiac glycosides, working directly on heart muscle. The drug improves the heart’s pumping ability or helps control its beating rhythm.

People with heart failure often develop swelling of the lower legs, feet, and ankles; this medicine improves by improving blood   circulation.

Digitalis is the collective term for the naturally occurring substances (also called cardiac glycosides) that are found in the leaves of the foxglove family and used to treat certain heart conditions.

Digitalis drugs are useful for treating conditions in which the heart beats irregularly or too rapidly (notably in atrial fibrillation), when it pumps too weakly (in congestive heart failure), or when the heart muscle is damaged and weakened following a heart attack.

Digitalis drugs can be used for a short period when the heart is working poorly, but in many cases they have to be taken indefinitely. Their effect does not diminish with time. In heart failure, digitalis drugs are often given together with a diuretic drug.

Prescribed for

The medicine is prescribed for the treatment of:

•   Mild to moderate chronic heart failure

•   Atrial fibrillation (irregular, fast heartbeat)

•   Certain types of congestive heart failure

Cautions and Warnings

This medicine should not be used in people with ventricular fibrillation, sick sinus syndrome or incomplete AV block, as it may cause a worsening of these conditions.

This medicine has been used to treat obesity. The risk of fatal heart rhythms associated with such treatment makes it extremely dangerous as weight-loss medication. Many heart disease symptoms may be associated with this medicine.

Kidney diseases may increase blood levels of this medicine. Your dosage may need adjustment.

Long-term use of this medicine may cause the body to lose potassium, especially since it is generally used in combination with diuretics. For this reason, be sure to eat a balanced diet and high-potassium foods (bananas, citrus fruits, melons, tomatoes).

Digitalis drugs can be toxic and, if blood levels rise too high, they may produce symptoms of digitalized poisoning.
