In 2025, Hypertension Canada released a new adult hypertension guideline specifically designed for primary care providers — including family physicians, nurse practitioners, and community pharmacists.
At Centrum Pharmacy, this update is highly relevant to our pharmacist-led hypertension management services and minor ailment care model. These changes will affect how many Canadians are diagnosed and treated for high blood pressure — and how early we intervene to prevent heart disease and stroke.
Lower Blood Pressure Threshold: Earlier Identification
Under the new guideline:
- A blood pressure (BP) of ≥ 130 / ≥ 80 mmHg is now considered elevated
- Previously, higher thresholds were used for diagnosis
This shift is based on strong evidence showing that cardiovascular risk increases even at these lower levels. Patients with BP in the 130–139 systolic range have higher rates of:
- Heart attack
- Stroke
- Heart failure
- Cardiovascular death
Earlier identification allows earlier intervention — particularly important for patients with diabetes, chronic kidney disease, or existing cardiovascular disease.
Diagnosis Still Requires Confirmation
To avoid overdiagnosis:
- BP must be measured using a validated automated (oscillometric) device
- Patients should rest 5 minutes before measurement
- At least 3 readings, 1 minute apart
- Out-of-office confirmation (home or ambulatory BP monitoring) is recommended
At Centrum Pharmacy, we help patients:
- Select validated BP monitors
- Learn proper home BP technique
- Interpret home BP logs
- Identify white coat or masked hypertension
When Do We Start Medication?
Pharmacotherapy is recommended for:
- BP ≥ 140/90 mmHg (general population)
- SBP ≥ 130 mmHg if high cardiovascular risk:
- Established cardiovascular disease
- Diabetes
- Chronic kidney disease
- Age ≥ 75
- Framingham Risk Score ≥ 20%
New Target: Systolic BP < 130 mmHg
For most adults with hypertension, the recommended goal is:
Systolic BP < 130 mmHg (if well tolerated)
This recommendation is informed in part by data from the landmark SPRINT trial, which showed reduced cardiovascular events with more intensive BP control.
However, aggressive lowering increases risk of:
- Hypotension
- Falls
- Electrolyte imbalance
- Acute kidney injury
In frail patients or those at fall risk, the goal becomes:
“As low as reasonably achievable.”
At Centrum Pharmacy, we individualize BP targets — especially in older adults.
Major Change: Start with Two Medications
The biggest practice shift:
➡ Initial low-dose combination therapy is now preferred
➡ Ideally as a single-pill combination (SPC)
First-line classes:
- ACE inhibitors (ACEIs)
- Angiotensin receptor blockers (ARBs)
- Thiazide or thiazide-like diuretics
- Long-acting dihydropyridine calcium channel blockers (DHP CCBs)
Beta-blockers are no longer first-line unless there is another indication (e.g., recent MI, heart failure with reduced EF, atrial fibrillation).
Why combination therapy?
- Faster BP control
- Better cardiovascular outcomes
- Improved adherence with single-pill combinations
Preferred Single-Pill Options
The guideline highlights:
- Irbesartan + hydrochlorothiazide
- ACEI (e.g., ramipril) + hydrochlorothiazide
ARBs may be better tolerated than ACEIs (less cough, lower angioedema risk).
At Centrum Pharmacy, we:
- Review provincial formulary coverage
- Assess tolerability and interaction risks
- Monitor electrolytes and kidney function
- Adjust therapy safely
Resistant Hypertension
If BP remains elevated on:
- ACEI/ARB
- Thiazide diuretic
- DHP CCB
➡ Add spironolactone
Potassium must be checked 2–4 weeks after starting or dose changes.
Our pharmacists coordinate lab monitoring and medication adjustments in collaboration with physicians at Orleans Family Health Clinic, reinforcing our Connected Care model.
Why This Matters for Centrum Pharmacy Patients
This guideline increases the number of Canadians who qualify for intervention — but it also improves cardiovascular prevention.
At Centrum Pharmacy, we provide:
- Comprehensive medication reviews
- Home BP monitoring support
- Pharmacist prescribing where permitted
- Ongoing monitoring and titration
- Close coordination with family physicians
- Support for patients without a family doctor
Through our 4 C’s Model:
- Complete Care – Full cardiovascular risk assessment
- Comprehensive Care – Medication + lifestyle strategy
- Caring Care – Individualized targets
- Connected Care – Direct integration with Orleans Family Health Clinic
If your BP has been “borderline,” it may now require action. Early intervention prevents stroke, heart attack, kidney disease, and heart failure.
