Mixed Agonist-Antagonist

A drug that combines with one receptor to produce an effect, but binds to another receptor with little to no effect.

Partial Agonist

A drug that binds to a receptor but only elicits a submaximal response compared to a full agonist.

Antagonist

A drug that binds to a receptor, preventing activation, and has no intrinsic effect on its own.

Competitive Antagonist

A drug that binds to the same receptor site as an agonist but does not activate it, effectively blocking the agonist's action.
