Wide distribution in rats, highest in liver, kidney, intestine, lung and stomach wall; low in brain and spinal cord
“In rats, vonoprazan and its metabolites were widely distributed with higher concentration in the liver, kidney, intestine, lung, and stomach wall than in the plasma, and were low in the brain and the spinal cord.”
