cody,
glad to see you are trying to control your risk factors. regarding blood pressure control, for most patients, I start with an ACEI like Altace. You are the appropriate (maximum) dose of the Altace. I will very often add a calcium channel blocker like norvasc second and maximize that dose -- norvasc 10 mg once per day. If this does not control blood pressure, I would next add HCTZ at 12.5 mg and increase to 25 mg if necessary. Beta blockers are not great blood pressure medications, but it is a reasonable addition. The dose can be increased if you have normal kidneys.
Based on your current meds, adding norvasc is a very reasonable next step. I would probably start with 5 mg and increase to 10 mg if you blood pressure is not improved in 2-4 weeks.
If you tolerate all the medications at one time, it is reasonable to take them in the morning. Your blood pressure will typically be higher during the day.
If you are tolerating the atenolol without side effects, that can also be increased, but starting norvasc sounds like a good first option. If you do not have coronary artery disease or another indication for a beta blocker, you could probably try stopping the beta blocker and starting norvasc and only add the beta blocker back if you need it.
You are probably right -- isolated systolic hypertension is sneaking up on you.
I hope this answers your questions. good luck and thanks for posting.
