Discovery and Early Use of Digitalis Plants
Early mentions and erratic use: Digitalis, derived from the foxglove plant, garnered early mentions in medical writings as far back as 1250 by the Welsh family of physicians known as the Physicians of Myddvai, who included it in their prescriptions [3].However, its utilization remained sporadic until the 18th century.During this period, William Withering, an esteemed English physician and botanist, significantly contributed to its understanding and medical application.Withering's seminal monograph, published in 1785, meticulously described the clinical effects of an extract of the foxglove plant, thus popularizing its medical use [4,5].William Withering's contributions: In his groundbreaking work titled "An Account of the Foxglove," Withering not only elucidated the indications for digitalis but also highlighted its potential toxicity [4,5].His meticulous observations led to recommendations regarding the optimal timing for gathering foxglove leaves for medicinal purposes.Withering's advocacy for digitalis extended to various ailments, including dropsy and epilepsy, marking a significant advancement in medical practice [4,5].
Chemical composition and mechanism: Digoxin, a prominent cardiac glycoside derived from digitalis, is therapeutic by inhibiting the Na+/K+ ATPase pump in cardiac muscle cells [4,5].This inhibition leads to an accumulation of intracellular calcium, thereby enhancing the efficiency of cardiac muscle contraction.This mechanism underpins digoxin's efficacy in managing conditions such as congestive heart failure and atrial arrhythmias [6].
Toxicity and visual effects: Despite its therapeutic benefits, digitalis possesses a narrow therapeutic window and can lead to toxicity in excessive doses.Symptoms of digitalis toxicity include vomiting, disturbed vision (xanthopsia), bradycardia, convulsions, unconsciousness, and potentially fatal outcomes [4,5].Notably, the visual disturbances associated with digitalis toxicity, including a yellow tint to vision, have been linked to the works of the renowned artist Vincent van Gogh during his "yellow period," providing a striking example of the intersection between medicine and art [4].

Isolation and Purification of Digoxin
Digoxin, a cardiac glycoside employed in treating heart conditions, was initially isolated in 1930 by Dr. Sydney Smith from the foxglove plant Digitalis lanata [6].The isolation process entailed extracting the glycosides from the woolly foxglove, yielding digoxin as one of the resultant compounds [6].Subsequently, the purification of digoxin involved breaking down its glycosidic bonds within the body, forming digitoxin and sugars [6].The historical significance of digoxin's discovery lies in its herbal origins rather than laboratory synthesis.In 1775, English physician William Withering discovered the therapeutic potential of the foxglove plant in treating conditions such as dropsy (edema) [5,7].This breakthrough led to the widespread use of digitalis for medical purposes.Digoxin continues to be derived from the foxglove plant through a modern manufacturing process, which involves extracting digitalis from dried foxglove leaves to produce pure digoxin for pharmaceutical applications [5,7].The purification and extraction of digoxin from Digitalis lanata have facilitated its extensive utilization in managing various cardiac conditions over the past century.This historical journey underscores the enduring importance of natural sources in drug discovery and development.

Early Clinical Applications and Controversies
Digoxin, a treatment for heart failure, has been in use for over two centuries since its introduction by William Withering in the late 18th century [8,9].Derived from the Digitalis purpurea plant, commonly known as foxglove, digoxin was initially employed to manage cardiac dropsy, now recognized as congestive heart failure [9].Despite its historical roots, the FDA only approved digoxin for heart failure treatment in the late 1990s [10].In recent years, its usage has declined due to the emergence of newer therapies demonstrating efficacy in reducing mortality rates in heart failure [9].However, digoxin remains integral in heart failure management, especially in cases involving systolic dysfunction and normal sinus rhythm [10,11].Its application has extended to conditions such as atrial fibrillation and post-myocardial infarction management [10].Nevertheless, recent studies have yielded mixed results regarding digoxin's impact on morbidity and mortality, sparking controversy surrounding its use [10,12].Despite these challenges, digoxin continues to be recommended among select heart failure patients in the latest guidelines, underscoring its enduring role in cardiovascular care [11,12].

Mechanism of Action
Digoxin exerts its primary mechanism of action by inhibiting the sodium-potassium adenosine triphosphatase (Na+/K+ ATPase) enzyme, particularly within the myocardium.This inhibition results in an accumulation of intracellular sodium, which diminishes the sodium-calcium exchanger's activity.Consequently, intracellular calcium levels elevate, facilitating increased calcium binding to troponin C and augmenting myocardial contractility [13].Furthermore, digoxin functions as a negative chronotropic agent, effectively reducing heart rate [6].Given its narrow therapeutic window, meticulous monitoring of serum digoxin levels is imperative to mitigate the risk of potential toxicity.

Pharmacokinetics
Digoxin, a cardiac glycoside medication, is widely used to treat various heart conditions, including congestive heart failure, atrial fibrillation, and certain cardiac arrhythmias [6].Its primary mechanism of action revolves around inhibiting the sodium-potassium adenosine triphosphatase (Na+/K+ ATPase), predominantly within the myocardium.This inhibition enhances myocardial contractility, stroke volume, and blood pressure while concurrently reducing heart rate [14].However, digoxin's therapeutic range is narrow, and its toxicity can manifest through symptoms such as nausea, vomiting, visual changes, and arrhythmias [6].Digoxin is incompletely absorbed when administered orally, with a significant portion cleared by the kidneys, resulting in 70-85% excretion via urine [14].The bioavailability of an oral dose varies from 50-90%, although gelatinized digoxin capsules have been reported to have a bioavailability of 100% [14][15].Typical dosages range from 0.01-0.02mg/kg for loading doses, followed by 0.125-0.25 mg/day for maintenance therapy [14].Despite being utilized for over two centuries, digoxin's usage has declined with the emergence of novel therapies; nevertheless, it remains an integral component of standard care for heart failure [6].Recent studies have yielded conflicting results regarding digoxin's impact on morbidity and mortality, necessitating further investigation and refinement of its future role based on emerging evidence [6].

Pharmacodynamics
About 70 to 80% of an oral digoxin dose is absorbed, mainly in the proximal part of the small intestine.The degree of binding to serum albumin is 20 to 30%.Digoxin is extensively distributed in the tissues, as reflected by the large volume of distribution [16].The pharmacodynamic effects of digoxin are intricately linked to its uptake in the heart following administration.Toxic symptoms associated with digoxin correlate with its concentration in the heart and serum levels [15].Given its narrow therapeutic window, factors, such as renal function, body weight, serum albumin concentration, and drug interactions, can significantly influence the pharmacokinetics and pharmacodynamics of digoxin [6,15].Despite its status as one of the oldest medications in cardiology, digoxin remains a valuable treatment option for conditions such as atrial fibrillation and heart failure.However, its utilization necessitates vigilant monitoring due to the potential for toxicity, particularly in cases involving supratherapeutic doses or chronic overexposure [6].The profound pharmacodynamic effects of digoxin on the cardiovascular system underscore its pivotal role in the management of various heart conditions.
