Which drug is quickly deactivated when exposed to light?

Sodium nitroprusside is known for its sensitivity to light, which leads to its rapid deactivation when exposed. This medication, often used for its potent vasodilating properties in treating hypertensive emergencies, can break down into cyanide and other byproducts when it is not adequately shielded from light, rendering it less effective or potentially harmful. Because of this characteristic, it is typically administered with protections like opaque bags or wrap, specifically designed to minimize light exposure.

Dabigatran, nitroglycerin, and warfarin have different storage and handling requirements. Although nitroglycerin can also be sensitive to light, it is usually the infusion of sodium nitroprusside that is emphasized in clinical practice due to the immediacy and significance of its light sensitivity. Warfarin is stable under light and does not have the same risks associated with degradation from light exposure.
