    Study Notes

    Pharmacokinetics Processes

    • Two main processes of transfer of drugs across cell barriers are lipid diffusion and aqueous diffusion
    • Lipid diffusion is characterized by the ability of drugs to dissolve in and pass through the lipid bilayer of the cell membrane
    • Aqueous diffusion involves the movement of drugs through aqueous pores or channels in the cell membrane

    Pharmacokinetic Processes

    • A specific pharmacokinetic process is the transfer of drugs across cell barriers
    • The three main areas for discussion in the lecture on pharmacokinetics are not specified, but typical areas of discussion in pharmacokinetics include absorption, distribution, metabolism, and excretion (ADME) of drugs.
