WebNov 21, 2024 · Digoxin and digitoxin are the main digitalis products. [ 1] Digoxin is absorbed quickly from the gastrointestinal tract with a bioavailability of between 75% and 95%. It is eliminated primarily through kidneys; therefore, it has a half-life of 36-48 hours in patients who have normal kidney function and 3.5-5 days in patients who are anuric. [ 2] WebDistribution is a necessary step for the active molecules to reach their pharmacological target. The extent of distribution determines the amount of drug to be administered in order to acheive suitable concentration levels. Distribution also affects the drug’s half-life. For some drugs, the distribution is the process that puts an end to an ...
