1TEST BANKTEST BANK for Drugs and Behavior 7thEditionDr. Anna HicksMemorial University of NewfoundlandChapter 1Some Basic PharmacologyCHAPTER SUMMARY•Drugs can have four different kinds of names: a chemical name, a generic name, at least onetrade name, and usually many street names.•Doses of a drug are usually described in terms of concentration (i.e., mg of drug/kg bodyweight).•Dose–response curves (DRCs) are graph curves that show changes in the effect of a drug thatare produced by changes in the dose.•The ED50(median effective dose) is the dose of a drug that either has a particular effect in 50percent of the subjects to whom it is given or produces in an individual an effect equivalent to50 percent of the maximum effect that the drug will have at any dose. The LD50(medianlethal dose) is the dose of a drug that will be lethal to 50 percent of the subjects.•The safety of a drug can be described by the TI (therapeutic index), which is the LD50dividedby the ED50.•When comparing two drugs that have the same effect, the drug with the lower ED50is themore potent. The drug with the greater maximum effect is the more effective.•All drugs have a number of effects. The effect that the drug is being consumed for is the mainor primary effect, and all others are side effects.•If one drug shifts the DRC of a second drug to the right, the drugs are said to be antagonistic.If the DRC is shifted to the left, the effects are additive. Potentiation or a superadditive effectoccurs if the effects of a drug mixture are greater than what might be expected if the effectswere simply added together.•Pharmacokinetics is the study of how drugs move into, around, and out of the body.•Parenteral administration involves injecting a drug through the skin, using a syringe and ahollow needle. Parenteral injections may be subcutaneous, intramuscular, intraperitoneal, orintravenous. Drugs may also be injected directly into veins through a permanently implantedcatheter or into the central nervous system through a permanently implanted cannula.•Drugs are absorbed from parenteral sites by diffusing into the blood through pores in thewalls of capillaries.

2•Drugs in the form of gases and/or smoke may be inhaled into the lungs and enter the blood.Drugs that are inhaled reach the brain more quickly than drugs taken by any other route.•Drugs taken orally must pass through the stomach before they can be absorbed from the smallintestine.•Molecules of drugs that are ionized (i.e., have an electric charge) are not lipid soluble and areabsorbed poorly from the digestive system. The rate of absorption of a drug can be altered bychanging the pH of the digestive system because this can alter the percentage of ionizedmolecules.•The pKa of a drug is the pH at which the molecules of a drug are 50 percent ionized.•Drugs that are not lipid soluble have difficulty passing through membranes and get into thebrain slowly because of the blood–brain barrier. Highly lipid-soluble drugs are sometimesabsorbed rapidly into body fat and are released slowly.•In transdermal administration, drugs are absorbed directly through the skin.•Factors that affect the distribution of drugs in the body are lipid solubility, the blood–brainbarrier, protein binding, and the presence of active and passive transport mechanisms.•In the kidney, most of the fluid in the blood is released into one end of the nephron. As thefluid passes through, water and nutrients are reabsorbed. Ionized drugs and many drugmetabolites are not reabsorbed. They pass through the length of the nephron and are excretedin the urine.•The liver, the body’s chemical factory, uses the process of metabolism to change drugmolecules into metabolites, which may then be eliminated by the kidneys. The liver controlsmetabolism using enzymes, which act as catalysts to speed up certain chemical reactions.•First-pass metabolism refers to the metabolism of a drug in the digestive system or liverbefore it gets into general circulation.•Enzymes can be stimulated by repeated use of a drug or by other drugs, or they can bedepressed by age, other drugs, and some foods.•Half-life is the time taken for the body to get rid of half of a circulating drug.•The therapeutic window refers to the range of blood levels of a drug between the lowesttherapeutically effective blood level and a level that causes undesirable side effects.Multiple Choices1-1.
