What are Cardiotonics examples?
Cardiotonic drugs are intended for treating cardiac insufficiency. This chapter focuses on cardiac glycosides isolated from leaves of various types of foxglove and strophanthus plant, and also a number of other plants such as lilies, periploca, oleander, hellebore, erysimum, jute, and Irish ballon.
Which drug is used in Cardiotonics?
Cardiotonic Agents
| Drug | Target | Type |
|---|---|---|
| Lisinopril | Renin | target |
| Dobutamine | Beta-1 adrenergic receptor | target |
| Dobutamine | Catechol O-methyltransferase | enzyme |
| Dobutamine | Beta-2 adrenergic receptor | target |
What are cardiac glycoside drugs?
Cardiac glycosides are medicines for treating heart failure and certain irregular heartbeats. They are one of several classes of drugs used to treat the heart and related conditions. These drugs are a common cause of poisoning.
What are inotropic drugs?
Inotropic agents, or inotropes, are medicines that change the force of your heart’s contractions. There are 2 kinds of inotropes: positive inotropes and negative inotropes. Positive inotropes strengthen the force of the heartbeat. Negative inotropes weaken the force of the heartbeat.
How Digitalis is useful in CHF?
Digoxin, also called digitalis, helps an injured or weakened heart pump more efficiently. It strengthens the force of the heart muscle’s contractions, helps restore a normal, steady heart rhythm, and improves blood circulation. Digoxin is one of several medications used to treat the symptoms of heart failure.
Which compound is used in digitalis poisoning?
Digoxin is a well-known cardiac glycoside and one of the oldest drugs used today in cardiovascular medicine. It has wide-ranging beneficial effects and continues to play an important role in the contemporary management of appropriately selected patients with heart failure and atrial fibrillation.
What are cardiac glycosides called?
The most recognized of these plants is foxglove (Digitalis purpurea), found in Africa and other parts of the world. It contains the cardiac glycosides digoxin, digitoxin, and digitonin, among several others. Digoxin at therapeutic levels is used to treat congestive heart failure, but becomes toxic at high doses.

What to know about cardiotonic-inotropic drugs study guide?
These are vital nursing interventions done in patients who are taking cardiac glycosides: Check drug dose and preparation carefully to avoid medication errors because drug has narrow safety margin. Do not administer drug with food and antacids to prevent decreased in drug absorption.
How are cardiac glycosides used as a cardiotonic agent?
Cardiac glycosides are cardiotonic agents from foxglove or digitalis plants. They exert their effects on the cardiac muscles by affecting levels of intracellular calcium. In turn, the contractility of the muscles is increased. Allows more calcium to enter during contraction, therefore increasing the force of contraction – positive inotropic effect.
What are the generic names for cardiotonic-inotropic drugs?
Here is a table of commonly encountered cardiotonic-inotropic drugs, their generic names, and brand names: Heart failure is a syndrome characterized by dysfunction of cardiac muscles. It can occur in a number of heart conditions which can overwork the heart muscles. Some of these conditions include:
