I have been on Lotensin for about 9 months. It seems to be relatively effective .... except everyday at about 5:00 PM my systolic BP rises above 155 for a few hours. Otherwise it remains between 120-140. First of all, I'm wondering if anyone has any insight into why this happens.

Secondly, I was considering switching to the new rennin blocker called Tekturna. Does anyone have any experience with this? Could you please share it with us. Thanks.
