What is jynarque?

What is Jynarque (and what is it used for)?

Jynarque is a brand name for tolvaptan, a medicine that works in the kidney to reduce urine production. It is prescribed for autosomal dominant polycystic kidney disease (ADPKD) to help slow the loss of kidney function over time.[1]

How does Jynarque work?

Tolvaptan blocks vasopressin (ADH) V2 receptors in the kidney. By blocking these receptors, it reduces the kidney’s ability to concentrate urine, which lowers the build-up of cyst-related fluid and helps slow progression of ADPKD.[1]

Who can take Jynarque?

Jynarque is intended for people with ADPKD who are at risk of rapid disease progression, based on clinical criteria used in prescribing.[1]

How is Jynarque taken?

The drug is taken by mouth and is typically used as a scheduled daily regimen (with dosing that can include multiple doses within a day). Exact dosing depends on the patient’s prescribing plan and response.[1]

What side effects do people ask about?

A common effect of tolvaptan/Jynarque is increased urination (and thirst) because it changes how the kidney handles water. Patients and clinicians also monitor for potential liver-related safety concerns, which is why regular lab monitoring is important during treatment.[1]
