A

psychological symptoms occur without use of the drug
anxiety, tension, stress

105
Q
  • Tolerance
A

need to take more of the drug to achieve the same effect
increased metabolism of drug

106
Q
  • Therapeutic Effect
A

desired/intended effect of the drug (drug indication).
(When a drug should not be used, it is called a contraindication.)

107
Q
  • Side Effect
A

undesirable effect in addition to the desired effect (not an allergy), i.e. drowsiness, dry mouth

108
Q
  • Toxic Effect
A

side effect that can be harmful or life threatening to the body (drug poisoning)

109
Q
  • Additive Effect
A

When the combined effect of two drugs, each producing the same biologic response by the same mechanism of action, is equal to the sum of their individual effects

110
Q
  • Synergistic Effect / Synergism
A

When the combined effect of two drugs is greater than the sum of their individual effects

111
Q

enzyme inducers

A

increase in the amount of liver enzymes, faster metabolism of drugs, duration of action is decreased

112
Q

enzyme inhibitors

A

inhibit liver enzymes, slow metabolism of drugs, increases duration and intensity of action
enzyme inhibitors → cimetidine (Tagamet®), erythromycin, allopurinol, Calcium Channel Blockers as a class, fluoxetine (Prozac®), short term alcohol ingestion

113
Q

Define concepts related to Pharmacokinetics (ADME) and factors that influence each of these processes.

A

Study of the processes of drug absorption, distribution, metabolism, and excretion

114
Q
  • Absorption
A

entrance of the drug into the bloodstream/circulation

Filtration-solids and fluids separate
Passive transport (diffusion) – drugs move from an area of high concentration to low concentration
Osmosis-diffusion across a semipermeable membrane enabled by water movement
Active transport-uses energy

115
Q

What are Schedule I drugs?

A

Drugs with high abuse potential and no accepted medical use.

Examples include heroin, hallucinogens, and marijuana; these drugs are not to be prescribed.

116
Q

What are Schedule II drugs?

A

Drugs with high abuse potential and accepted medical use.

Examples include narcotics (morphine and pure codeine), cocaine, amphetamines, and short-acting barbiturates (Amobarbital, Secobarbital); no refills without a new written prescription from the physician.

117
Q

What are Schedule III drugs?

A

Drugs with moderate abuse potential and accepted medical use.

Examples include moderate- and intermediate-acting barbiturates, dronabinol, anabolic steroids, and preparations containing codeine plus another drug; prescription required, may be refilled five times in 6 months when authorized by the physician.

118
Q

What are Schedule IV drugs?

A

Drugs with low abuse potential and accepted medical use.

Examples include phenobarbital, chloral hydrate, zolpidem (Ambien), and antianxiety drugs (Librium, Valium); prescription required, may be refilled five times in 6 months when authorized by the physician.

119
Q

What are Schedule V drugs?

A

Drugs with limited abuse potential and accepted medical use.

Examples include narcotic drugs used in limited quantities for antitussive (codeine) and antidiarrheal purposes (diphenoxylate, Lomotil); drugs can be sold only by a registered pharmacist; buyer must be 18 years old and show identification. Some states require a prescription for this class of drugs.

120
Q

What does incompatibility refer to?

A

Usually refers to physical alterations of drugs that occur before administration when different drugs are mixed in the same syringe or other container

121
Q

What are additive effects?

A

When the combined effect of two drugs, each producing the same biologic response by the same mechanism of action, is equal to the sum of their individual effects

122
Q

What is summation in pharmacology?

A

When the combined effect of two drugs, each producing the same biologic response but by a different mechanism of action, is equal to the sum of their individual effects

123
Q

What does synergism mean?

A

When the combined effect of two drugs is greater than the sum of their individual effects

124
Q

What is bioavailability?

209

210

214
Q

First-Pass Effect

A

After oral administration, all drugs are absorbed into the portal circulation, which transports the drugs to the liver before they are distributed throughout the body.

Some drugs are metabolized significantly as they pass through the liver this first time.

This effect is referred to as first-pass metabolism.

It can significantly reduce bioavailability and the amount of active drug that reaches the general circulation.

215
Q

Half-life

A

The half-life of a drug is the time required for the blood or plasma concentration of the drug to fall to half of its original level.

For example, after two half-lives only 25 percent of the drug that was absorbed remains in the blood.

Half-life is important in determining the frequency of drug administration.

216
Q

Incompatibility

A

Usually refers to physical alterations of drugs that occur before administration when different drugs are mixed in the same syringe or other container

217
Q

Bioavailability

A

Bioavailability is the percentage of the dose of a drug that is actually absorbed into the bloodstream.

Differences in drug formulation, route of administration, and factors that affect GI absorption can influence bioavailability.

A particular drug may be manufactured by many different drug companies and sold under different trade names.

In these situations, the amount of drug may be the same in each product, but the product may be different because of particle size, binders, fillers, and tablet coating.

These differences may alter bioavailability. There have been examples of this in the past. Now, however, the Food and page 25Drug Administration (FDA) regulates and requires bioavailability testing.

218
Q

Reconstitution

A

the process of adding a liquid diluent to a dry ingredient to make a specific concentration of liquid

219
