Abstract
Therapeutic compositions containing chimeric natriuretic peptides for treating chronic kidney disease alone, heart failure alone, or chronic kidney disease with concomitant heart failure are described. The therapeutic compositions have enhanced stability characteristics to facilitate storage and delivery by provisioning apparatuses under conditions of elevated temperature and mechanical stress. Methods for increasing the stability of therapeutic compositions containing chimeric natriuretic peptides are further described.
