application of osmosis in medicine

Neurology. Water travels from high concentration to low concentration and keeps moving by osmosis until the equilibrium is reached, that is when the concentration of both solutions is the same. Osmotic drug delivery is the controlled delivery of an oral drug through the use of osmotic pressure.
