[Clinical study of meproscillarin rates of inactivation and persistence, bioavailability and maintenance dose]

With a rate of inactivation of about 40% and a bioavailability of about 70% corresponding approximately to that of digoxin 14-hydroxy-3beta-[(4-O-methyl-alpha-L-rhamnopyranosyl)oxy]-14beta-bufa-4,20,22-trienolide (meproscillarin, Clift) is--according to our results--a new therapeutic possibility for cardiac decompensated patients, especially in the presence of renal failure. The number of side effects was low. Occasionally diarrhoea occurred which, however, only in a few cases required treatment or discontinuance of therapy.
