Hi Cody,
You are on a very good regimen for someone with coronary disease. The basics are:
aspirin
beta blocker
ace inhibitor
statin
You are correct that your blood pressure management is an important part of risk reduction. 3-4 days of elevated pressures is not enough to concern me. If that trend continues over the next 6-8 weeks, I would consider tweaking your medications.
Are there any drugs on the market that target systolic blood pressure and do not effect diastolic pressures?
We don't worry about a low diastolic pressure as long is it is below 85-90. A diastolic pressure of 70-80 is just fine.
Can it possibly be a different generic from the pharmacy, if so what of the above drugs would most likely effect the higher systolic pressure?
It is unlikely caused from a bad generic drug. I recommend generics over most brand name medications. I would keep following your blood pressure 1-2 x per day for the next 6-8 weeks. If it continues talk to your doctor about changing your regiment. Keep a log of your pressures and vary the time you check each day (ex. odd days check when you get up and after dinner, even days after lunch and before bed).
I hope this answers your questions. thanks for posting.
With the Inderal, the generics seem OK.
My speculation is that, in general, the generics are not good quality meds. Remember the old saying: "The bitterness of poor quality remains long after the sweetness of low price is forgotten".
