Formation constants of the silver(I) complexes with some amino-alcohols have been determined at 25 degrees C in 0.5 M KNO(3) by means of two independent potentiometric measurements employing glass and silver electrode. The ligands considered are: sec-butylamine, 2-amino-1-propanol, 2-amino-1-methoxy-propane, 2-amino-2-methyl-1-propanol

Dissolution of diclofenac from compressed discs containing mixtures of a diclofenac salt and a basic excipient, in various w/w ratios, was examined. Two diclofenac salts, diclofenac deanol (DDNL) and diclofenac tert-butylamine, and the basic excipient 2-amino-2-methyl-1,3-propanediol (AMPD) were examined. Inclusion
