In this article, we will discuss Sulindac (Distribution). So, let’s get started.
Distribution
Sulindac, and its sulfone and sulfide metabolites, are 93.1, 95.4, and 97.9% bound to plasma proteins, predominantly to albumin. Plasma protein binding measured over a concentration range (0.5-2.0 μg/mL)
was constant. Following an oral, radiolabeled dose of sulindac in rats, concentrations of radiolabel in red
blood cells were about 10% of those in plasma. Sulindac penetrates the blood-brain and placental barriers. Concentrations in brain did not exceed 4% of those in plasma. Plasma concentrations in the placenta and in the fetus were less than 25% and 5% respectively, of systemic plasma concentrations. Sulindac is excreted in rat milk; concentrations in milk were 10 to 20% of those levels in plasma. It is not
known if sulindac is excreted in human milk.
