摘要

Preparation of a peptide acid addition salt (I) comprises: (a) reacting a starting acid addition salt (II) of a basic peptide with a mixed bed ion exchanger (or a mixture of acidic and basic ion exchangers) in presence of a diluent; (b) reacting the obtained free basic peptide with an inorganic or organic acid to give (I); and (c) removing the diluent. Independent claims are included for: (i) (I) obtained by the process (specifically in lyophilized form); (ii) a pharmaceutical preparation containing (I) obtained by the process, together with auxiliaries, carriers and/or structuring agents; and (iii) the production of a preparation as in (ii), by adding the auxiliaries, carriers and/or structuring agents at least partially before removing the solvent.
