Study Notes
Nitrates
- Used to reduce frequency and severity of angina attacks
- Mechanism of action: vasodilation, reducing preload and myocardial oxygen demand
- Examples:
- Glyceryl trinitrate (GTN)
- Isosorbide mononitrate (ISMN)
- Isosorbide dinitrate (ISDN)
Beta Blockers
- Used to reduce frequency and severity of angina attacks
- Mechanism of action: reducing heart rate and blood pressure, decreasing myocardial oxygen demand
- Examples:
- Atenolol
- Metoprolol
- Propranolol
Calcium Channel Blockers
- Used to reduce frequency and severity of angina attacks
- Mechanism of action: vasodilation, reducing myocardial oxygen demand
- Examples:
- Amlodipine
- Felodipine
- Verapamil
Potassium Channel Openers
- Used to reduce frequency and severity of angina attacks
- Mechanism of action: vasodilation, reducing myocardial oxygen demand
- Examples:
- Nicorandil
Ranolazine
- Used to reduce frequency and severity of angina attacks
- Mechanism of action: reducing late sodium current, decreasing myocardial oxygen demand
- Example:
- Ranolazine
Anti-Platelet Agents
- Used to prevent thrombus formation and reduce risk of acute coronary syndrome
- Examples:
- Aspirin
- Clopidogrel
Statins
- Used to reduce cholesterol levels and prevent progression of atherosclerosis
- Examples:
- Atorvastatin
- Simvastatin
Angina Medications
- Nitrates are used to reduce frequency and severity of angina attacks by vasodilation, reducing preload and myocardial oxygen demand
- Examples of nitrates include Glyceryl trinitrate (GTN), Isosorbide mononitrate (ISMN), and Isosorbide dinitrate (ISDN)
Beta Blockers
- Beta blockers reduce frequency and severity of angina attacks by reducing heart rate and blood pressure, decreasing myocardial oxygen demand
- Examples of beta blockers include Atenolol, Metoprolol, and Propranolol
Calcium Channel Blockers
- Calcium channel blockers reduce frequency and severity of angina attacks by vasodilation, reducing myocardial oxygen demand
- Examples of calcium channel blockers include Amlodipine, Felodipine, and Verapamil
Potassium Channel Openers
- Potassium channel openers reduce frequency and severity of angina attacks by vasodilation, reducing myocardial oxygen demand
- Nicorandil is an example of a potassium channel opener
Ranolazine
- Ranolazine reduces frequency and severity of angina attacks by reducing late sodium current, decreasing myocardial oxygen demand
- Ranolazine is an example of this type of medication
Anti-Platelet Agents
- Anti-platelet agents prevent thrombus formation and reduce risk of acute coronary syndrome
- Examples of anti-platelet agents include Aspirin and Clopidogrel
Statins
- Statins reduce cholesterol levels and prevent progression of atherosclerosis
