BIOSYNTHESIS OF DIGITOXIN PDF

Further information: Digoxin toxicity The occurrence of adverse drug reactions is common, owing to its narrow therapeutic index the margin between effectiveness and toxicity. Gynaecomastia enlargement of breast tissue is mentioned in many textbooks as a side effect, thought to be due to the estrogen -like steroid moiety of the digoxin molecule, [20] but when systematically sought, the evidence for this is equivocal as of [update]. This inhibition causes an increase in intracellular sodium levels, resulting in decreased activity of the sodium-calcium exchanger , which normally imports three extracellular sodium ions into the cell and transports one intracellular calcium ion out of the cell. The reversal of this exchanger causes an increase in the intracellular calcium concentration that is available to the contractile proteins. Increased intracellular calcium lengthens phase 4 and phase 0 of the cardiac action potential , which leads to a decrease in heart rate.
