What is the physical state of a drug with the fastest rate of absorption?
Gas
What does the rate of absorption of a drug depend on?
Physical state of the drug
What is the biological half-life of a drug?
The time it takes for half of the drug's compound to be eliminated from the body
What is the drug response specificity based on?
Drug-receptor affinity
Which type of agents can be endogenous or exogenous?
Psychotropics
What is the basis for the therapeutic index (TI) of a drug?
The ratio of the drug's lethal dose (LD) to its effective dose (ED)
What is the formula for calculating the therapeutic index (TI) of a drug?
TI = LD50 / ED50

To study the body's actions on drugs
What is the purpose of pharmacodynamics?
To study the effects of drugs on the body at the cellular level
What is the relationship between a drug's biological activity and its dose?
The lower the dose, the higher the biological activity

To understand drug absorption, distribution, metabolism, and excretion
What is the therapeutic index (TI) of a drug based on?
Dose-response relationship
