The United States Food and Drug Administration approved verapamil for the treatment of high blood pressure in 1981. (sciencedaily.com)
To examine changes in circulating proteins in response to verapamil treatment, the researchers used liquid chromatography-tandem mass spectrometry of blood serum samples from subjects diagnosed with Type 1 diabetes within three months of diagnosis and at one year of follow-up. (sciencedaily.com)
The top serum protein altered by verapamil treatment was chromogranin A, or CHGA, which was downregulated with treatment. (sciencedaily.com)

In contrast, the elevated levels of CHGA at Type 1 diabetes onset did not change in control subjects who did not take verapamil. (sciencedaily.com)
CHGA levels were also easily measured directly in serum using a simple ELISA assay after a blood draw, and lower levels in verapamil-treated subjects correlated with better endogenous insulin production as measured by mixed-meal-stimulated C-peptide, a standard test of Type 1 diabetes progression. (sciencedaily.com)
In the second year, CHGA levels continued to drop in verapamil-treated subjects, but they rose in Type 1 diabetes subjects who discontinued verapamil during year two. (sciencedaily.com)
