1 points

QUESTION 14

The amount of drug required to cause an effect is referred to as:

relative potency

adverse effect

maximal efficacy

dose-effect relationship

1 points

QUESTION 15

The amount of medication needed to produce a specific response in 50% of patients is called the:

dose-effect relationship

frequency distribution curve

median effective dose

maximal efficacy drug

Transcription factors

Antagonists

Ligand-gated ion channels

G protein-coupled receptor systems

Answer 1: Transcription factors.

There are three general categories of cell-surface receptors: ion channel-linked receptors, G-protein-linked receptors, and enzyme-linked receptors.

Answer 2: maximal efficacy

Efficacy is generally independent of potency/affinity, and is related to the maximum effect that a particular drug is capable of producing.

Answer 3: Median effective dose

An effective dose (ED) in pharmacology is the dose or amount of drug that produces a therapeutic response.
