Ularitide is a synthetic form of urodilatin, a naturally occurring human natriuretic peptide that is involved in regulating blood pressure and the excretion of water and sodium from the kidneys. Urodilatin is produced in the kidney and excreted into the urine, and thus exists in low levels naturally in the systemic blood circulation. When injected into the blood, ularitide appears to cause diuresis (urine output) and natriuresis (sodium excretion), as well as vasodilation. Ularitide is currently in Phase 2 development as a potential treatment for patients with acute decompensated heart failure (ADHF).

Cơ Chế Tác Dụng : Ularitide is a synthetic form of urodilatin, a naturally occurring human natriuretic peptide that is involved in regulating blood pressure and the excretion of water and sodium from the kidneys. Urodilatin is produced in the kidney and excreted into the urine, and thus exists in low levels naturally in the systemic blood circulation. When injected into the blood, ularitide appears to cause diuresis (urine output) and natriuresis (sodium excretion), as well as vasodilation. Ularitide is currently in Phase 2 development as a potential treatment for patients with acute decompensated heart failure (ADHF). Ularitide, a synthetic form of urodilatin, belongs to the family of natriuretic peptides. Urodilatin stimulates the intracellular guanylyl cyclase as the intracellular domain of the natriuretic peptide receptor A (NPR-A), the enzyme that catalyzes the conversion of GTP to cGMP [7]. Activation of cGMP-dependent protein kinase inhibits sodium reabsorption via an amiloride-sensitive channel and furthermore results in smooth muscle relaxation via a decrease in intracellular Ca2+ concentration. Thus, ularitide is an intrarenal paracrine regulator of sodium and water homeostasis.

Chỉ Định : Investigated for use/treatment in congestive heart failure.
