What is a common side effect of ACE inhibitors?
What is a common side effect of ACE inhibitors?
Why do ACE inhibitors cause a cough?
Why do ACE inhibitors cause a cough?
ACE inhibitors cause a cough due to the accumulation of bradykinin, a peptide normally broken down by the angiotensin-converting enzyme. Elevated bradykinin levels stimulate sensory nerves in the respiratory tract and promote mild airway inflammation, leading to a persistent dry cough in some patients. Switching to angiotensin receptor blockers (ARBs), which do not affect bradykinin, may alleviate this side effect.

- Negative inotropes: Decrease contractility (e.g., beta-blockers, verapamil for hypertension or arrhythmias).
- Positive chronotropes: Increase heart rate (e.g., atropine, epinephrine for bradycardia).
- Negative chronotropes: Decrease heart rate (e.g., beta-blockers, verapamil for tachycardia, atrial fibrillation).

- Phase 3: Repolarization caused by potassium efflux.
- Phase 4: Resting phase (membrane potential maintained by sodium-potassium pump).
Nitrates and Cardiac Workload
- Nitrates convert to nitric oxide, causing vasodilation.
- Reduces preload (venous return to the heart) and afterload (arterial resistance), lowering cardiac workload and oxygen demand.
Modifiable vs. Non-modifiable Hyperlipidemia Risk Factors
- Modifiable: Diet, physical inactivity, obesity, smoking.
- Non-modifiable: Age, race, gender, family history.
Fibric Acid Derivatives Adverse Effects
- Gastrointestinal disturbances.
- Gallstones.
- Myopathy.
ASCVD Risk Assessment Factors
- Age, gender, race, total cholesterol, HDL cholesterol, blood pressure, diabetes, smoking.
Digoxin Mechanism of Action
- Inhibits the sodium-potassium ATPase pump, leading to increased intracellular calcium.
- Increases myocardial contractility.
Aspirin Mechanism of Action
- Inhibits platelet activation via irreversible enzyme antagonism. blocks prostaglandin synthesis.
Clinical Presentation and Treatment of Aplastic Anemia
- Fatigue, infections, bleeding, pancytopenia.
- Treat with supportive care, blood transfusions, and platelet transfusions as needed.
Pain Receptor Types
- Thermal nociceptors: Respond to extreme temperatures.
- Mechanical nociceptors: Respond to intense mechanical forces.
- Chemical nociceptors: Detect chemical irritants, toxins or inflammatory mediators.
