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

Answer 1

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.
