Answer 1

5

Question 2

Answer 2

Schedule I

Question 3

Drugs that are used medically and have high abuse potentials: opioid analgesics (e.g., codeine, hydromorphone, methadone, meperidine, morphine, oxycodone), central nervous system (CNS) stimulants (e.g., cocaine, methamphetamine), and barbiturate sedative–hypnotics (e.g., pentobarbital).

Answer 3

Schedule II

Question 4

Drugs with less potential for abuse than those in Schedules I and II, but abuse of which may lead to psychological or physical dependence: androgens and anabolic steroids, some depressants (e.g., ketamine, pentobarbital), some CNS stimulants (e.g., methylphenidate), and mixtures containing small amounts of controlled substances (e.g., codeine, barbiturates not listed in other schedules). These drugs and substances have an accepted medical use in the United States.

Question 44

Beers Criteria for Potentially Inappropriate Medications Used in Older Adults

Answer 44

The American Geriatrics Society Beers Criteria, a list of medications that are generally considered best avoided in older adults and specifically in those with certain diseases, confirms that toxic medication effects and drug-related problems affect the safety of older adults.

Question 45

Drugs that do not act on receptor sites

Answer 45

(1) Antacids, which act chemically to neutralize the hydrochloric acid produced by gastric parietal cells and thereby raise the pH of gastric fluid (2) Osmotic diuretics (e.g., mannitol), which increase the osmolarity of plasma and pull water out of tissues into the bloodstream (3) Drugs structurally similar to nutrients body cells require (e.g., purines, pyrimidines) can be incorporated into cellular constituents, such as nucleic acids, which interfere with normal cell functioning. Several anticancer drugs act by this mechanism. (4) Metal chelating agents, which combine with toxic metals to form a complex that can be more readily excreted

Question 46

Decreased intestinal absorption of drugs

Answer 46

which occurs when drugs combine to produce nonabsorbable compounds. For example, drugs containing aluminum, calcium, or magnesium bind with oral tetracycline (if taken at the same time) to decrease its absorption and therefore its antibiotic effect.

Question 47

Increased metabolism rate of drugs

Answer 47

Activation of drug-metabolizing enzymes in the liver, therefore decreasing the drug’s effects.

Question 48

Newly developed drugs have been extensively tested using a five-phase process before being marketed for general use.

Answer 48

In phase 0, drug testing occurs in animals and small groups of humans. In Phase 1, a few doses are given to a certain number of healthy volunteers. In Phase 2, a few doses are given to a certain number of subjects with the disease or symptom for which the drug is being studied. In In phase 3, the drug is given to different populations and different dosages by using the drug in combination with other drugs. in a double-blind, placebo-controlled design, half of the subjects receive the new drug and half receive a placebo. In Phase 4, the FDA allows the drug to be marketed and requires manufacturers to continue post-marketing monitoring and electronic report submission of the drug's safety and effectiveness.

Question 49

are more standardized in their chemical characteristics, more consistent in their effects, and less likely to produce allergic reactions.

Answer 49

Synthetic compounds
