An agonist increases the activity of a receptor above its basal level, whereas an inverse agonist decreases the activity below the basal level.A neutral antagonist has no activity in the absence of an agonist or inverse agonist but can block the activity of either.The efficacy.n agonist increases the activity of a receptor above its basal level, whereas an inverse agonist decreases the activity below the basal level.
