Nitroglycerin Paste: The Tiny Rescue That Reopens Blood Flow

In this episode of Diabetic Fit Files, Dr. G explains how topical nitroglycerin paste works as a vasodilator to improve microcirculation and rescue threatened skin flaps, ischemic digits, and compromised grafts. The episode covers its mechanism (nitric oxide release), clinical indications, historical background, and why it can help in diabetic wound care. Key clinical pearls and cautions are summarized, including when it may help, common side effects (headache, hypotension), major contraindications (concurrent PDE-5 inhibitors, severe hypotension, anemia), and why it should never replace urgent surgical intervention when needed.
