EXAM
A __ antagonist acts by competing for the same receptor with the
endogenous ligand. So that the receptor cannot be activated by the
endogenous ligand. Basal activity still ocurring. - ANSWERS-
competitive antagonist
A __ antagonist produces a comformational change in the receptor that
blocks that receptor being activated by the ligand. Basal activity still
occurs - ANSWERS-non-compeitive antagonist
An __ agonist prevents the ligand from binding the receptor and blocks
the activity of the receptor so that even basal activity cannot occur -
ANSWERS-inverse agonist

EXAM
__ (Kd) is the concentration of the drug required to occupy 50% of the
receptors at equilibrium. - ANSWERS-equilibrium dissociation constant

value means the drug has __ affinity with that receptor. - ANSWERS-
higher; lower
Any other sites in the body the drug binds to other than its target are
referred to as ___. - ANSWERS-unintended sites
In general, a drug that has high selectivity for its intended site or
receptor has a __ Kd value, which means that it has __ affinity for that
receptor. - ANSWERS-low;high
