Answer» CORRECT choice is (c) Selective for peripheral H1 receptors and opposed to CNS receptors Explanation: These are the newer drugs and they are MUCH more selective for the peripheral H1-receptors involved in allergies as opposed to the H1-receptors in the CNS. Therefore, these drugs provide the same relief with MANY fewer ADVERSE SIDE effects. |
