Warning/ Precautions:
Drug-Drug Interactions (DDIs):
Monitoring Parameters:
Thiazide Diuretics
examples: Chlorthalidone( hydroton) , indapamide (Lozol), hydrochlorothiazide (hydrodiuril), Metolazone (Zaroxolyn)
Class: Thiazide Diuretics
Indication: Management of hypertension. Effective in treating hypertension in elderly and African American populations
Mechanism of Action: Inhibits sodium and chloride reabsorption in the distal convoluted tubule, causing increased excretion of sodium, chloride, water, and potassium
Effects of mechanism of Action: decrease blood volume, cardiac output, and peripheral vascular resistance
Adverse Effects: Hyponatremia, hypokalemia, HYPERcalcemia, hyperuricemia, hypovolemia, hyperglycemia, elevated lipids (LDL, triglycerides).
Absolute Contraindications: hypersensitivity, patients with hypersensitivity to sulfonamide-derive drugs (sulfa allergy)
Pregnancy: –
Warning/ Precautions: Use with caution in patients with history of acute gout unless the patient is on uric acid lowering therapy
Not effective in patients with low GFR, high salt intake.
Not effective in CrCl <30 mL/min
Drug-Drug Interactions (DDIs): NSAIDS, Lithium (decrease lithium clearance which increases toxicity)
Monitoring Parameters: Assess electrolytes and renal function 2-4 weeks after initiating therapy or changing doses.
NON Dihydropyridines (DHP)

Monitoring Parameters: –
NON Dihydropyridines (DHP)
examples: Diltiazem ER, Verapamil (Canalan)
Class: Calcium Channel Blockers
Indication: Management of hypertension.
Mechanism of Action: inhibits calcium ions form entering vascular smooth muscle and myocardial
Effects of mechanism of Action: peripheral arterial and coronary artery vasodilation, ALSO has negative Inotropy (decreased contractility) and negative chronotropy (decreased heart rate).
Adverse Effects: Diltiazem: edema, headache, constipation, conduction disturbances, bradycardia, heart failure.
Verapamil : edema, constipation, gingival hyperplasia, headache, conduction disturbances, bradycardia, dizziness, heart failure exacerbations.
Absolute Contraindications:
avoid use in patients with HFrEF.
Pregnancy: –
Warning/ Precautions: –
Drug-Drug Interactions (DDIs): avoid routine use with beta blockers, CP3A4 major substrate and moderate inhibitor->dose aadjustments required for simvastatin an lovastatin, as well as be careful with interactions with other drugs involved with CYP3A4

Dihydropyridines (DHP).
examples:end in -DIPINE: Amlodipine (Norvasc), Nifedipine (Procardia) etc.
Class: Calcium Channel Blockers
Indication: Management of hypertension.
Mechanism of Action: inhibits calcium ions form entering vascular smooth muscle and myocardial
Effects of mechanism of Action: peripheral arterial and coronary artery vasodilation
Adverse Effects: pedal edema (D/C if this happens), headache, dizziness, flushing, potential for reflex tachycardia (short acting agents only).
Absolute Contraindications:–

Warning/ Precautions:
Drug-Drug Interactions (DDIs):
Monitoring Parameters:
Pearls:
Angiotensin converting enzyme inhibitors (ACEi)
examples: end in -PRIL. Lisinopril (Privinil/Zestril), Enalapril (Vasotec)
Class: Ace inhibitors
Indication: Management of hypertension.
Mechanism of Action:Prevents conversion of angiotensin ! to angiotensin II by way of the angiotensin converting enzyme. this prevents actions such as vasoconstriction, sympathetic activation, and aldosterone release.
Effects of mechanism of Action: decreased vasoconstriction and decreased aldosterone( corticosteroid that stimulates absorption of sodium by the kidneys) release.
Adverse Effects: HYPERkalemia, acute renal failure (in its with severe bilateral renal stenosis), dry cough( because of bradykinin), angioedma, hypotension.
Absolute Contraindications:pregnancy, history of angioedema, 36 hours of an angiotensin receptor/ neprilysin inhibitor[ARNI-sacubritil/valsartan], bilateral renal stenosis
Pregnancy: DO NOT USE
Warning/ Precautions: –Do not initiate if potassium > 5 mmol/L.Discontinue if potassium >5.6 mol/L
Drug-Drug Interactions (DDIs):
Monitoring Parameters: Assess electrolytes and renal function 2-4 weeks after initiating therapy or changing doses.
Pearls: 1.drug of choice in its with diabetes, heart failure, post MI, stroke, and/ or CKD due to target organ protection
- do not use in combo with RAAS drugs
- protect the myocardium from remodeling/ hypertrophy in patients with heart failure
