Document Summary
Pharmacokinetics: the "movement" of the drug through the body. Drugs: non-food chemical that alters one or more normal biological processes in living organisms. Psychoactive drugs: site of action is on the central nervous system. Drugs are therapeutic - they are not good or bad (caffeine vs. lsd), they are just drugs. They alter on-going processes, not create new functions. Drugs like tracts they are similar too (blood stream is basic - inject basic drugs, stomach is acidic - eat acidic drugs : example, don"t eat cocaine, it"s basic) Has an impact on how fast the drug will act (quick of slow effect) Drug molecules can have difficulty passing molecules; impeding the process to get to the site of action, the brain, and is at risk of being metabolized. Lipid or water: can the drug pass through fat tissues; likely - lipid soluble, water soluble tend to be metabolized and have a difficult time passing membranes.
