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

The inhibitory effect of inorganic phosphate on the activity determination of isoenzymes of alkaline phosphatase (AP) in diethanolamine (DEA), glycine and 2-amino-2-methyl-1,3-propandiol (AMPD) buffer was studied. This effect depends on the buffer used and isoenzyme investigated. Especially the placental isoenzyme

Isotachophoresis seems a likely candidate for a reference method, as it is more accurate and precise than common routine methods. The response is highly linear and depends on a well defined transport number of the leading ion, stability of the
