YES, grandma has been on BP and cholesterol medication for more years than she can remember, and YES it has affected the ability to obtain erection. However, I am 64, and have now found that although I can no longer get HARD on a daily basis, if I wait a few days, I can get rock hard and function normally for that session. My docs say thats the normal effects of the medication and AGE, and I should use Viagra etc, however Viagra on a daily basis is cost prohibitive. He did recommend Slidenafil, generic Viagra, which I did a whole thread about many months ago. It still causes the after effect Headache, but at least it only cost about $5 and not $40 a pop.
