A 60-year-old male asked:
Does clonidine 0.1 mg., as a blood pressure prescription, have the effect of slightly slowing the heart beat/rate? is it a beta blocker?

It's not: Clonidine is a centrally acting alpha-2 stimulator (what we call an agonist). It works on the feedback loop for adrenaline responsive nerves, and rather effectively. ~4% of people will experience bradycardia with it.

Bradycardia: Yes, Clonidine can cause the heart rate to slow. It is an Alpha agonist, not a beta blocker.

Yes...and No.: Clonidine's central nervous system effects reduce the release of stress substances thereby lowering BP and mildly slowing ones heart rate. There a re two potential mechanisms for these effects, one of which is alpha2 receptor stimulation. It is not a beta blocker.
