Discuss the types of physiological barriers to drug activity, and how these barriers operate.
View the bilayer lipid plasma membrane along with a phospholipid diagram.
introduce the hydrophilic and hydrophobic sections.
Indicate that small molecules, like steroid hormones, can pass through into the cell by diffusion.
Explain when equilibrium is reached in the diffusion process.
indicate that water soluble drug molecules will have a more difficult time passing through the membrane, and require speciric proteins to pass them through.
Read a case study and discuss the cause and effect and possible reasons for the cause.
