Abstract
Abstract New S-adenosylmethionine salts have been prepared which are stable indefinitely with time, even at elevated temperatures. The new salts correspond to the formula: ##STR1## in which X is the equivalent of an organic sulphonic acid of pK less than 2.5, and possess therapeutic activity in numerous fields of human therapy.
