Document Summary

Drug experience involves two branches of science o. Concerns the absorption, distribution, biotransformation, and excretion of drugs (-movement) how the body acts on drugs (adme and its time course) A drug"s dose is computed according to a person"s body weight. Either the site where a drug is taken or how a drug is taken. Can strongly influence the effects that a drug has. Usually in forms of pills, capsules, powders, or liquids. Pass through the stomach -> absorbed primarily through small intestine. Amount of food in digestive tract when the drug is taken is a major factor in determining the effect of the drug. Drug is absorbed into the blood more slowly than other routes. Liver is major site of metabolization of most drugs. Drug must be soluble and stable in stomach fluid. Stomach acid will destroy anything that isn"t strong enough to withstand it.
