Cardiotoxic

Cardiotoxicity is a type of toxicity that affects the heart. It can be caused by a variety of drugs, toxins, and other environmental factors. It is characterized by a variety of symptoms, including arrhythmias, conduction disturbances, and cardiac failure. Cardiotoxic drugs can lead to serious and even fatal complications if used incorrectly. The pharmacological effects of cardiotoxic drugs are due to their ability to interfere with the normal functioning of the heart and its associated structures. They can either cause direct damage to the myocardium or indirectly disrupt the normal functioning of the heart by inhibiting its ability to pump blood efficiently. The activity of cardiotoxic drugs can be divided into two categories: arrhythmogenic and cardiostimulant. Arrhythmogenic drugs are those that can cause arrhythmias, or abnormal heart rhythms. Examples of these drugs include digoxin and quinidine. Cardiostimulants are drugs that can increase the heart rate and contractility, and can be used to treat congestive heart failure and arrhythmias. Examples of these drugs include dobutamine and epinephrine.
