Question
Chapter 10, Problem 58Q
Interpretation Introduction
Interpretation:
Reason for why thalidomide was banned and FDA rejected the approval of marketing of this drug in US several times until recently and the purpose of approval of using thalidomide has to be explained.
Concept introduction:
Drugs: Drugs are molecules which are taken from an external source to change the normal functioning of the body. The action of drug is in molecular level and the design of many drugs are in such a way that it mimics a particular neurotransmitter or hormone. Drugs bind with receptors showing an increased or decreased effect.
