Cardiac glycoside meaning

Cardiac glycoside definitions

Cardiac glycosides are a group of naturally occurring compounds that have been used for centuries to treat various heart conditions. Derived from plants such as foxglove, these compounds have a profound effect on the heart muscle and can be both beneficial and potentially harmful depending on the dosage.

Function

Cardiac glycosides work by inhibiting the sodium-potassium pump in heart muscle cells. This results in an increase in intracellular calcium levels, which in turn improves the force and efficiency of heart contractions. As a result, these compounds are often used in the treatment of heart failure and certain types of irregular heart rhythms.

Common examples

Digitalis, obtained from the foxglove plant, is one of the most well-known cardiac glycosides. Other examples include ouabain and strophanthin, which have been used in traditional medicine for centuries.

Side effects

While cardiac glycosides can be effective in treating heart conditions, they can also have serious side effects if not used properly. These include nausea, vomiting, vision disturbances, and even life-threatening heart rhythm disturbances. It is important for patients taking these medications to be closely monitored by a healthcare provider.

In conclusion, cardiac glycosides are a powerful class of medications that have been used for generations to treat heart conditions. While they can be highly effective, they also carry some risks, so it is important for patients to work closely with their healthcare provider to ensure safe and appropriate use.
