9.1      Overview of drug dosing problem
9.1.1    Problems of scaling up doses from animal systems
9.1.2    Basing dosing on size, area, weight of recipient
9.1.3    Vast differences between adults in terms of genetics, metabolism
9.1.4    Dosing in children – children are NOT smaller adults!
9.1.5    Pharmacokinetics – drug distribution, metabolism, excretion, breakdown
9.1.6    Conventional dosing assumes drug goes everywhere in the body
9.1.7    Targeted therapies – a model for future nanomedical systems?

9.2      From the animal dosing to human clinical trials
9.2.1    Importance of picking an appropriate animal model system
9.2.2    Does drug dosing really scale?
9.2.3    The human guinea pig in clinical trials and beyond

9.3      Traditional drug dosing methods
9.3.1    Attempts to scale up on basis of area
9.3.2    Attempts to scale up on weight/volume

9.4      Genetic responses to drug dosing
9.4.1    All humans are not genomically equivalent!
9.4.2    Predicting on basis of family tree responses
9.4.3    SNPs, chips, and beyond…predicting individual drug response
9.4.4    After the $ ???? individual genome scan… more closely tailored individual therapies

9.5      Dosing in the era of directed therapies – a future model for nanomedical systems?
9.5.1    How directed therapies change the dosing equation
9.5.2    Current generation directed antibody therapies dosing
9.5.3    Some typical side effects of directed therapies
9.5.4    Nanomedical systems are the next generation of directed therapies

9.6      Most directed therapies are nonlinear processes!
9.6.1    Meaning of nonlinear processes
9.6.2    Some examples of how a few directed therapies work
