Yes, I am still taking it as well as propranolol. The latter is another beta blocker and the perindopril is an ACE inhibitor. Both have research reporting their value in treating PD in addition to hypertension. Still another class with similar features are the sartins (losartin is one). It is a bit odd that the three distinct drugs would all do double duty in such a specific manner.

As to your question about if bringing your BP down helped the PD, I will answer it a little differently and say that the high pressures that I experienced (250/200!!) definitely made the PD worse.

Finally, about the blood vessels relaxing in the brain, you might be interested in researching a supplement called "vinpocitine". It is an extract from Vinca minor (periwinkle) and is used for that very purpose. I have yet to try it, but it seems to have a good safety profle. Available at the health food store.
