Lisinopril
"I am currently aged 55.  I am a little overweight for my height but have always been very active and workout at least twice a week.  I have never had high blood pressure or any symptoms.  During my last physical, my blood pressure was in the 150/90s.  My Doctor prescribed 10mg of lisinopril. I was pleased to find out that it also had no side effects.  After only 2 days of taking the medication, my blood pressure was back down in the 120/80s range.  Seems to work for me so far."
