Which of the following is true for receptor action of the drug
Ref-KDT 6/e p41 Intrinsic activity is a measure of the ability of a drug that is bound to the receptor to generate an activating stimulus and produce a change in cellular activity. Both agonists and antagonists can bind to a receptor.
An antagonist has both an intrinsic activity and affinity for receptor
An antagonist has the affinity but no intrinsic activity for the receptor
A paial antagonist has no affinity or intrinsic activity for the receptor
Intrinsic action and affinity are not impotant for drug action
