Answer:
"I should chew sugar-free gum or drink water to reduce dry mouth."
Explanation:
Clonidine is an agonist at the alpha-2 receptors ( adrenergic receptors ).
There is an area in the central nervous system (lateral hypothalamus) responsible for the secretion of saliva ,as the clonidine acts on the central alpha-2 receptors ,it causes inhibition of the secretion of the saliva resulting in dry mouth.
As the alpha-2 receptors are inhibitory receptors (Gi-coupled ) clonidine results in decreased sympathetic autonomic nervous system outflow by activating alpha-2 receptors in the CNS.
