FAA 2nd class medical

I'm an antique pilot from the early 60's. I have a P ASEL&S + I ticket. I
have about 3500 hrs with about 600 hrs. actual instrument time. most of the
time is in Mooney's. I want to get back up to speed and go for my Commercial
and CFI. I'm older now and I have slightly higher blood pressure then I did
12 years ago when I stopped flying. I am taking medication for this. Also
years ago equilibrium was tested by standing on one foot but I don't recall
if the eyes had to be closed or not. My medication may be having an effect
because now it's a little harder for me to do that. I can do it easily with
my eyes open. Does anyone know the protocol if one is taking medication for
b/p applying for a 2nd class medical and how equilibrium is tested today?
Thanks for any information
