Etymology
The term 'natriuretic' derives from the combination of the prefix 'natri-' which comes from the Latin 'natron' meaning sodium or sodium-rich alkaline substance, and the Greek 'ouretikos' meaning 'to urinate'. This word was first introduced in the medical field to describe compounds that cause increased sodium excretion via urine. Natriuretic peptides, which include atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP), were identified in the 1980s and have since been studied for their role in cardiovascular physiology and their potential in treating heart-related conditions. The understanding of natriuretic substances has expanded with ongoing research in nephrology and cardiology, emphasizing their importance in maintaining electrolyte balance and blood pressure regulation.
