|
antagonist medications |
the group of medications that prevent endogenous or exogenous agonist chemicals from reaching cell receptor sites and initiating or altering a particular cellular activity |

|
|
noncompetative antagonists |
Medications that permanently bind with receptor sites and prevent activation by agonist chemicals.
|
|
competative antagonists |
The medications that temporarily bind with cellular receptor sites, displacing agonist chemicals.
|
|
partial agonist |
A chemical that binds to the receptor site but does not initiate as much cellular activity or change as other agonists do; lowers the efficacy of other agonist chemicals present at the cells.
|
|
antimicrobials |
The medications used to kill or suppress the growth of microorganisms.
|
|
