Term
4 elements of the Nuclear Receptor
Definition
AF-1 Site, DNA Binding Domain, Hinge, Ligand Binding Domain
Term
3 Types of membrane receptors
Definition
Tyrosine Kinase, G-Protein Linked, Ion Channels
Term
3 types of PPAR
Definition
Gamma: Master regulator in formation of fat cells
Alpha: Active during fasting, fatty acids are released into blood to liver for b-oxidation
Delta: expressed all the time, regulator of fatty acid oxidation. High expression = lean, resistant to obesity.
Term
Bioavailability
Definition
F = dose absorbed / dose administered (IV)
Term
Solubility
Definition
[drug]oil/drug[water]
Term
Volume of Distribution
Definition
Vd = amount in body/plasma concentrations
Term
Therapeutic plasma concentration
Definition
dose/Vd

Vd = dose/plasma concenstration

If drug is high, Vd is low, if drug is low, Vd is high
Term
Phase 1/Phase 2 Metabolism
Definition
Phase 1: Addition of OH/NH2
Phase 2: Conjugation of very reactive groups with highly water soluble substrate
Term
Drug Loss
Definition
Q(Ca-Cv)
Term
Clearance (as in, measuring how much of a drug is cleared by an organ).
Definition
CL = Q(Ca-Cv)/Ca
