Differentiate between the terms agonist, antagonist, affinity, and efficacy in terms of drug use/abuse.
What will be an ideal response?
Drugs either facilitate or inhibit transmission at synapses. A drug that blocks a neurotransmitter is an antagonist, whereas a drug that mimics or increases the effects is an agonist. Investigators say that a drug has an affinity for a receptor if it binds to it, like a key into a lock. Affinities vary from strong to weak. A drug's efficacy is its tendency to activate the receptor. A drug that binds to a receptor but fails to stimulate it has a high affinity but low efficacy.
