Abstract

Pharmacokinetics of ketoprofen nanosystem was studied in outbred rats after single endotracheal administration. Ketoprofen was analyzed in blood serum and tissues by HPLC with UV detection. After endotracheal administration of the nanosystem, ketoprofen rapidly appears in systemic blood flow and its concentration in blood serum reaches maximum after 15 min. The maximum drug concentration in tissues was observed near the site of introduction, namely, in lungs Ketoprofen showed moderate penetration in tissues with high vascularization, and weak penetration in tissues with moderate vascularization. After endotracheal administration of the nanosystem, only small amount of ketoprofen overcomes the blood brain barrier.

Blood Brain Barrier

The blood brain barrier is a border that separates blood from cerebrospinal fluid. Discover the latest search on this highly selective semipermeable membrane here.

Blood Brain Barrier Chips

The blood brain barrier (BBB) is comprised of endothelial cells that regulate the influx and outflux of plasma concentrations. Lab-on-a-chip devices allow scientists to model diseases and mechanisms such as the passage of therapeutic antibodies across the BBB. Discover the latest research on BBB chips here.
