Study Notes
Module 04: Pharmacology of the Cardiovascular and Respiratory Systems
- This module covers different drug classes impacting the cardiovascular and respiratory systems.
- The online modules are the primary learning tool, and the companion guide complements the online slides.
- If any discrepancies arise between the guide and online module, the online module should be consulted.
- Do not share the module companion guide with students not enrolled in PHAR 370.
- This course content is subject to the Queen's University Academic Integrity Policy.
Section 01: Drugs for the Treatment of Hypertension
- Hypertension, or high blood pressure, is a significant cardiovascular disease prevalent in North America.
- Chronic high blood pressure damages blood vessels in vital organs: kidneys, heart, and brain.
- Damage to the kidneys can increase kidney failure risk.
- Heart damage can lead to heart failure, angina, or stroke.
- Brain damage may result in dementia.
- Blood pressure control involves antihypertensive drugs.
Section 02: Drugs for the Treatment of Angina and Heart Failure
- Coronary artery disease (CAD) is characterized by narrowed coronary arteries and heart ischemia.
- Angina pectoris, a common consequence of ischemia, is chest pain accompanied by shortness of breath.
- Angina is often triggered by exertion, excitement, eating, or exposure to cold.
- Angina can be treated with organic nitrates (e.g., nitroglycerin and isosorbide dinitrate), Beta blockers (e.g., Propranolol), and calcium channel blockers (e.g., nifedipine).
Section 03: Drugs for the Treatment and Prevention of Atherosclerosis
- Atherosclerosis is a common cause of death, involving plaque buildup in arteries, decreasing blood flow.
- Behavioural risk factors like obesity, smoking, lack of exercise, and hypertension contribute to the condition.
- Lipoproteins (e.g., chylomicrons, VLDL, LDL, HDL) are carriers for lipids in the bloodstream.
- LDL ("bad" cholesterol) is considered a major risk factor for atherosclerosis.
- High levels of LDL can be treated using statins (e.g., lovastatin, simvastatin, fluvastatin), fibric acid derivatives (e.g., gemfibrozil), bile acid binding resins, or PCSK9 inhibitors (e.g., alirocumab and evolocumab).
Section 04: Drugs for the Treatment of Disorders of Coagulation
- Hemostasis is a process that stops bleeding after vessel injury.
- The coagulation cascade involves vasoconstriction, platelet plug formation, and blood coagulation.
- Anticoagulants prevent clot formation, while thrombolytics dissolve existing clots.
- Warfarin is an oral anticoagulant that inhibits vitamin K-dependent clotting factors.
- Heparin and low molecular weight heparins (LMWHs) are injectable anticoagulants that enhance antithrombin III activity.
- Platelet inhibitors (e.g., aspirin, clopidogrel) decrease platelet aggregation.
Section 05: Drugs for the Treatment of Asthma and COPD
- Asthma is an inflammatory respiratory disease characterized by airway narrowing and increased airflow resistance, causing shortness of breath, coughing, wheezing.
- COPD is a chronic airflow limitation disease, that encompasses chronic bronchitis and emphysema.
- Elevated airway inflammation is a common factor of both conditions.
- Treatment often involves bronchodilators (e.g., short and long-acting ẞ2 agonists, antimuscarinics), and anti-inflammatory agents (e.g., corticosteroids, leukotriene receptor antagonists, anti-IgE antibodies).
