Pharmacokinetics of digoxin in C.A.P.D.

The peritoneal elimination of digoxin during C.A.P.D. was studied in five patients. The plasma half life of digoxin varied from 54 hours to 141 hours. Only 7 to 24 micrograms was eliminated via the peritoneal route during 3 to 4 days C.A.P.D. treatment. The total urinary elimination during the same period ranged from 11 to 57 micrograms. It is concluded that adjustment of dose is not necessary when starting C.A.P.D.
