All drugs are not created equal even if the pharmacopoeia seems to suggest they are. Factors that affect bioavailability among drugs of the same type (especially oral drugs) include not only disintegration and absorption rates but also the amount of food taken before or with the dose, interactions with other drugs, the physical state of the patient, and the "first-pass effect" upon drug with high liver clearance.

D004077	Digoxin	A cardiotonic glycoside obtained mainly from Digitalis lanata; it consists of three sugars and the aglycone DIGOXIGENIN. Digoxin has positive inotropic and negative chronotropic activity. It is used to control ventricular rate in ATRIAL FIBRILLATION and in the management of congestive heart failure with atrial fibrillation. Its use in congestive heart failure and sinus rhythm is less certain. The margin between toxic and therapeutic doses is small.
