Ularitide
DrugBank Accession Number
DB05034
Background

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).

Mechanism of action

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.

Interactions

Drug Interactions
This information should not be interpreted without the help of a healthcare provider. If you believe you are experiencing an interaction, contact a healthcare provider immediately. The absence of an interaction does not necessarily mean no interactions exist.
DrugInteraction
AbacavirUlaritide may increase the excretion rate of Abacavir which could result in a lower serum level and potentially a reduction in efficacy.
AceclofenacUlaritide may increase the excretion rate of Aceclofenac which could result in a lower serum level and potentially a reduction in efficacy.
AcemetacinThe therapeutic efficacy of Ularitide can be decreased when used in combination with Acemetacin.
AcetaminophenUlaritide may increase the excretion rate of Acetaminophen which could result in a lower serum level and potentially a reduction in efficacy.
Acetylsalicylic acidAcetylsalicylic acid may decrease the excretion rate of Ularitide which could result in a higher serum level.
