organic base the salts are administered in the same manner as the parent acid compounds suitable inorganic bases to form these salts include for example the hydroxides carbonates bicarbonates or alkoxides of the alkali metals or alkaline earth metals for example sodium potassium magnesium calcium and the like the preferred salt is the sodium salt suitable organic bases include the following amines lower mono di and tri alkylamines the alkyl radicals of which contain up to three carbon atoms such as methylamine dimethylamine trimethylamine ethylamine di and triethylamine methylethylamine and the like mono di and trialkanolamines the alkanol radicals of which contain up to three carbon atoms such as mono di and triethanolamine alkylenediamines which contain up to six carbon atoms such as hexamethylenediamine amino sugars such as glucosamine cyclic saturated or unsaturated bases containing up to six carbon atoms such as pyrrolidine piperidine morpholine piperazine and their n alkyl and n hydroxyalkyl derivatives such as n methylmorpholine and n 2 hydroxyethyl piperidine as well as pyridine furthermore there may be mentioned the corresponding quaternary salts such as the tetraalkyl for example tetramethyl alkyl alkanol for example methyltrimethanol and trimethyl monoethanol and cyclic ammonium salts for example the n methyl pyridinium n methyl n 2 hydroxyethyl morpholinium n n dimethyl morpholinium n methyl n 2 hydroxyethyl morpholinium n n dimethyl piperidinium salts which are characterized by good water solubility in principle however there can be used all the ammonium salts which are physiologically compatible the transformations to the salts can be carried out by a variety of methods known.
