Otsuka’s Tolvaptan is an investigational selective antagonist of the vasopressin V2 receptor, which is located predominantly in the kidney and plays a role in the regulation of fluid retention in the body. Vasopressin V2 antagonists work by selectively blocking the V2 receptor.
Taro Iwamoto, CEO, president and COO of Otsuka Pharmaceutical Development & Commercialization, said: “Otsuka is pleased that the FDA advisory committee supports the potential approval of tolvaptan, an investigational selective V2-vasopressin receptor antagonist. We believe tolvaptan, if approved by the FDA, has the potential to be an important treatment option for people with hyponatremia.”
