Definition
Noun A naturally occurring compound obtained from certain plants, used medicinally to increase the force of contraction of the heart muscle, primarily in the treatment of heart failure.
Usage
"Cardiac glucoside" is a technical term used in pharmacology, medicine, and botany. It refers to a specific class of active chemical substances.
Examples
- The doctor prescribed a cardiac glucoside to improve the patient's heart function.
- Digoxin is a well-known cardiac glucoside derived from the foxglove plant.
- The therapeutic use of cardiac glucosides requires careful monitoring due to their narrow safety margin.
Advanced Usage
- The term is often used interchangeably with cardiac glycoside in modern scientific literature, as "glycoside" is the more chemically precise term for this class of compounds.
Variants and Related Words
- Cardiac glycoside (n): The more common and chemically precise synonym for cardiac glucoside.
- Digitalis (n): A general term for preparations derived from the foxglove plant (), which contain cardiac glucosides/glycosides.
- Cardiotonic (adj/n): Describing a substance that strengthens the heart's contractions; a drug with such an effect.
Synonyms
- Cardiac glycoside
- Digitalis glycoside
- Cardiotonic steroid
Notes on Meaning
While the core meaning is stable, note that "glucoside" is a somewhat older term. In contemporary scientific and medical contexts, cardiac glycoside is the preferred term, as not all these compounds contain a glucose molecule (the "gluco-" prefix specifically refers to glucose).
Noun
- obtained from a number of plants and used to stimulate the heart in cases of heart failure
