Nitroglycerin transdermal patches are a critical medication for preventing angina episodes in coronary artery disease patients. Proper application involves selecting clean, dry, hairless skin on the upper body, applying the patch firmly, and rotating application sites daily. The patch is typically worn for 12-14 hours followed by a 10-12 hour patch-free period to maintain effectiveness and prevent tolerance. Patients should follow dosing instructions carefully and be aware of potential side effects like dizziness when standing up.
Key Points Explained:
-
Application Site Selection
- Choose clean, dry, hairless skin on the chest or outer upper arm
- Clip (don't shave) hair if needed to avoid skin irritation
- Avoid areas below elbows/knees and skin folds where absorption may vary
- Rotate application sites daily to prevent skin irritation (Nitroglycerin Transdermal Patch)
-
Proper Application Technique
- Press patch firmly into place with palm of hand for 10-15 seconds
- Ensure edges are well sealed to prevent premature detachment
- Apply only one patch at a time (never multiple patches simultaneously)
-
Wearing Schedule
- Typical wear time: 12-14 hours daily
- Followed by 10-12 hour patch-free period to prevent tolerance
- Helps maintain medication effectiveness over time
-
Dosing Considerations
- Starting dose typically 0.2-0.4 mg/hr
- Dosage adjustments should only be made under medical supervision
- Never cut patches to adjust dose as this affects drug delivery
-
Precautions
- Avoid sudden position changes to prevent dizziness
- Limit alcohol as it may intensify side effects
- Remove before MRI procedures or swimming/bathing
- Store unused patches at room temperature away from moisture
-
Purpose and Mechanism
- Prevents angina by relaxing blood vessels and reducing heart workload
- Not for treating active angina attacks
- Works through sustained transdermal absorption over several hours
Patients should always follow their specific doctor's instructions regarding application times and dosing, as individual needs may vary based on medical history and response to treatment.
