All of the following statements about clonidine are true except
|A||It is an alpha adrenergic agonist|
|B||It can cause dry mouth as an adverse effect|
|C||Prazosin completely antagonizes its action|
|D||It inhibits sympathetic outflow.|
a. Clonidine is an alpha-2 agonist that acts by decreasing the central sympathetic outflow.
b. Sedation, dry mouth and rebound hypertension are the principal adverse effects associated with clonidine.
c. Prazosin is an α1 selective blocker, therefore it is not able to block alpha-2 mediated actions.
