Drug introduction

Nitroglycerin patch is a medication used to treat patients with heart disease. The patch contains nitroglycerin, which is absorbed through the skin and helps dilate blood vessels, thereby increasing blood supply to the heart. This helps reduce heart pain and discomfort. Patients should use the patch correctly according to their doctor's recommendations, usually changing it once a day. During use, avoid using any cosmetics or creams on the patch area to ensure proper absorption of the medication. When using, follow your doctor's dosage instructions and do not overdose. If severe dizziness, hypotension, or other adverse reactions occur, seek medical attention immediately. Remember, nitroglycerin patches are for prescription use only and should not be shared with other people.

Dosage

How to use: Apply the Glycerin Trinitrate Patch to dry, hairless skin, avoiding wrinkles. Clean and dry skin before each patch change and do not use on areas with cuts or damaged skin.
