Cardiac glycosides like digoxin, primarily inhibit the sodium-potassium pump (Na+/K+ ATPase), an important protein located on the surface of cardiomyocytes (cardiac muscle cells). [ 1 ] [ 2 ] Using ATP (the cell’s energy currency), this protein facilitates the transport of extracellular potassium ions (K+) into the cell while exporting sodium ...
Cardiotoxicity is the occurrence of heart dysfunction as electric or muscle damage, resulting in heart toxicity. [1] This can cause heart failure, arrhythmia, myocarditis, and cardiomyopathy in patients. [2] Some effects are reversible, while in others, permanent damage requiring further treatment may arise.
They are indicated to treat diseases related to the heart or the vascular system (blood vessels), such as hypertension, hyperlipidemia, coagulation disorders, heart failure and coronary artery disease. [1] These drugs are prescription-only medicines, meaning that they should be administered strictly under a doctor’s instruction and can only ...
Beta-adrenergic receptors are found on cells of the heart muscles, smooth muscles, airways, arteries, kidneys, and other tissues that are part of the sympathetic nervous system and lead to stress responses, especially when they are stimulated by epinephrine (adrenaline). Beta blockers interfere with the binding to the receptor of epinephrine ...
The most important adverse side effects are muscle problems, an increased risk of diabetes mellitus, and increased liver enzymes in the blood due to liver damage. [5] [65] Over 5 years of treatment statins result in 75 cases of diabetes, 7.5 cases of bleeding stroke, and 5 cases of muscle damage per 10,000 people treated. [34]
This class of drugs is usually well tolerated. Common adverse drug reactions (ADRs) include: dizziness, headache, and/or hyperkalemia.Infrequent ADRs associated with therapy include: first dose orthostatic hypotension, rash, diarrhea, dyspepsia, abnormal liver function, muscle cramp, myalgia, back pain, insomnia, decreased hemoglobin levels, renal impairment, pharyngitis, and/or nasal ...
Generally, drugs outlined within the ATC code C should be included in this category. Please see WP:PHARM:CAT for more information. ... Cardiac stimulants (1 C, 38 P)
In terms of inotropic activity, excessive cardiac glycoside dosage results in cardiac contractions with greater force, as further calcium is released from the SR of cardiac muscle cells. Toxicity also results in changes to heart chronotropic activity, resulting in multiple kinds of dysrhythmia and potentially fatal ventricular tachycardia ...
