Intravenous Stable Isotope

The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) supports a wide range of medical research through grants to universities and other medical research institutions across the country. The Institute also supports government scientists who conduct basic, translational, and clinical research across a broad spectrum of research topics and serious, chronic diseases and conditions related to the Institute's mission. In addition, the NIDDK supports research training for students and scientists at various stages of their careers and a range of education and outreach programs to bring science-based information to patients and their families, health care professionals, and the public.

Stable isotopes have been used safely in clinical research for decades and have contributed seminal insights into human metabolism. In many cases, stable isotopes allow a generation of knowledge that may not be possible by any other method. Under the directive of the NIH Sterile Products for Human Administration (SPHA) Executive Committee and the NIH Office of Research Services and Compliance (approved 10/2021), stable isotopes used in clinical human metabolic studies must meet certain specified minimum requirements. Pine pharmaceuticals was initially approved by the NIH Office of Deputy Director of Clinical Care in August 2016 and the decision re-affirmed by the NIH Sterile Products for Human Research Committee (SPHA) on July 24th, 2018. The decision to continue using Pine Pharmaceuticals, LLC followed extensive year-long vetting and an external audit commissioned by the NIH CC Office of Research Support and Compliance (ORSC). A quality agreement was implemented in February 2019 and is in place between Pine Pharmaceuticals, LLC and NIH Pharmacy and NIDDK.
