Study Notes
Sildenafil and Nitrates
- Combining sildenafil (Viagra) with nitrates can lead to a significant drop in blood pressure, potentially fatal.
- Sildenafil enhances the vasodilatory effects of nitrates.
Administering Nitroglycerin
- Use an infusion pump for precise delivery of intravenous nitroglycerin.
- Nitroglycerin should not be mixed with other medications to avoid interactions.
- Special administration sets designed for nitroglycerin are essential due to absorption by standard plastic sets.
- Continuous monitoring of vital signs is required in intensive care settings.
ACE Inhibitors and Persistent Cough
- A patient starting on enalapril (Vasotec) should be assessed for a persistent cough, a common side effect of ACE inhibitors.
- Other symptoms like vertigo, tinnitus, and orthopnea are not associated with enalapril.
Calcium Ion Antagonists
- These drugs work by dilating coronary arteries and peripheral blood vessels, which increases myocardial blood flow and reduces workload.
- Dilation reduces the heart's oxygen demand and improves delivery to the myocardium.
Use of Nitroglycerin Paste
- It is crucial to rotate application sites for nitroglycerin paste to prevent skin irritation.
- Gradually reduce the dose of topical nitroglycerin upon discontinuation over 4 to 6 weeks.
- Implement periodic 8- to 12-hour nitrate-free intervals to avoid tolerance.
Nitroglycerin Translingual Spray
- Avoid using the spray near fire and do not shake the container to maintain drug integrity.
- The spray must not be swallowed or inhaled; proper administration is by spraying under or on the tongue.
Managing Nitrate-induced Headaches
- Acetaminophen can be used to treat nitrate-induced headaches, which can be a mild to severe side effect of nitroglycerin patches.
- Tolerance to headaches often develops after weeks of treatment, and headaches do not necessitate dosage adjustments or cessation of the medication.
