Annette is diagnosed with hypertension. Provide four classes of drugs used to manage it and give examples in each group. List five complications that may arise if she is not properly managed.

Four classes of drugs used to manage hypertension are:

1. ACE inhibitors - Examples include lisinopril, enalapril
2. Calcium channel blockers - Examples include amlodipine, diltiazem
3. Diuretics - Examples include hydrochlorothiazide, furosemide
4. Beta blockers - Examples include metoprolol, atenolol

Five complications that may arise if hypertension is not properly managed include:
1. Stroke
2. Heart attack
3. Kidney damage
4. Vision problems
5. Peripheral artery disease

Classes of Drugs for Hypertension Management:

1. Diuretics:
- Loop diuretics: Furosemide, Bumetanide
- Thiazide diuretics: Hydrochlorothiazide, Chlorthalidone

2. Beta-blockers:
- Non-selective: Propranolol, Nadolol
- Selective: Metoprolol, Bisoprolol

3. Angiotensin-converting enzyme (ACE) inhibitors:
- Captopril, Lisinopril, Ramipril

4. Angiotensin II receptor blockers (ARBs):
- Losartan, Valsartan, Candesartan

Complications of Unmanaged Hypertension:

1. Heart failure: Increased blood pressure strains the heart, leading to progressive weakening and failure.
2. Stroke: Hypertension is a major risk factor for stroke, a blood clot or bleeding in the brain.
3. Kidney disease: High blood pressure can damage the kidneys, leading to kidney failure.
4. Eye damage: Uncontrolled hypertension can lead to retinal damage, potentially causing blindness.
5. Arterial aneurysm: Weakened arteries caused by hypertension can form dangerous aneurysms that may rupture and cause life-threatening bleeding.
