Key result
Long-term intravenous infusion of atrial natriuretic peptide in conscious dogs decreased mean arterial pressure from 90 to 74 mm Hg by day 4, with no significant long-term effect on GFR.

Does intravenous infusion of atrial natriuretic peptide reduce mean arterial pressure and increase sodium excretion in conscious dogs?
Long-term infusion of atrial natriuretic peptide in conscious dogs produces a sustained reduction in mean arterial pressure despite only transient effects on sodium excretion and glomerular filtration rate.
Granger et al. (1986) studied this question. Synthetic atrial natriuretic peptide vs. Baseline was evaluated on Glomerular filtration rate, sodium excretion, and mean arterial pressure. Long-term intravenous infusion of atrial natriuretic peptide in conscious dogs decreased mean arterial pressure from 90 to 74 mm Hg by day 4, with no significant long-term effect on GFR.
