II. Management: General Guidelines
- See patients back at one month after starting agent
- Significantly improves compliance
- BP requires 1 month on agent to equilibrate
- Maximize compliance
- Work with patients to reduce adverse effects
- Switch to other agents if adverse effects significant
- Do not be overzealous
- Risk of overcorrection of Blood Pressure
- Avoid lowering diastolic pressure <70 mmHg
- Greater tolerance for elevated BP with increased age
- Study of 484 Swedish men over 70 from 1982-1992
- Risk if Diastolic Blood Pressure lowered below 90
- Increased cardiac event risk 3.9x
- Controlled for confounding factors
- Reference
- Consider nighttime dosing
- Advantages
- Associated with decreased cardiovascular events and improve Blood Pressure control
- Benefit may best in patients who do not dip their Blood Pressure overnight
- Non-dippers: Older, Diabetes Mellitus, Chronic Kidney Disease, Resistant Hypertension
- Consider 24 hour ambulatory monitoring to define unclear cases
- Disadvantages
- Risk of non-compliance
- Do not switch to nighttime dose if patient can not remember that dose
- Risk of Orthostatic Hypotension and Fall Risk at night
- Risk of non-compliance
- Indications to switch at least one medication to nighttime dosing
- Three or more antihypertensives used
- Best medications for nighttime dosing
- Angiotensin Converting Enzyme Inhibitors (ACE Inhibitors)
- Angiotensin Receptor Blockers
- Calcium Channel Blockers
- Alpha Blockers
- Beta Blockers
- Avoid Diuretics over night

III. Management: Choose agents with best outcome data
- Medications that prevent Hypertension vascular sequelae
- Diuretics
- ACE Inhibitors
- Calcium Channel Blockers
- Beta-Blockers
- Indicated in patients with known Coronary Artery Disease or chronic, stable Systolic Dysfunction
- Medications that prevent Left Ventricular Hypertrophy
- Most effective at reducing LVH risk
- ACE Inhibitors (e.g. Lisinopril)
- Diuretics (e.g. Chlorthalidone)
- Beta-Blockers (e.g. Metoprolol)
- Least effective at reduced LVH risk
- Reference
- Most effective at reducing LVH risk
