Ron,

Isradipine was mentioned at the PAN forum in February. This calcium channel blocker was shown to block calcium in dopamine-producing cells (in rats), thus reducing stress, and eventually the cells started producing dopamine again.

So I came home from PAN and contacted my doctor. She agreed to start me on isradipine. I've been on it for 2 months now - nothing miraculous to report. But I'll be patient and see how I am in 6 months - 9 months - 12 months.
