OPTImizing Precision of Hypertension Care to Maximize Blood Pressure Control Pilot (OPTI-BP Pilot)

The HTN PRA App will be used to adjust standard of care medication dosages for high blood pressure drugs which may include: thiazide diuretic (water pill), usually called hydrochlorothiazide (HCTZ) or chlorthalidone, and an ACE inhibitor or an angiotensin receptor blocker.

Blood sample for plasma renin activity activity will be obtained at least once (at baseline) and if BP is not controlled after 1-3 months, an additional blood sample may be obtained.
