硝化甘油貼片（Transdermal nitroglycerin patch）用於預防心絞痛。為了維持藥物吸收的穩定性並避免皮膚產生耐受性或接觸性皮膚炎，必須採取輪流更換貼敷部位（Rotate sites）的原則，且貼敷處需保持皮膚完整、無毛。不可剪裁貼片，因為這會破壞控釋薄膜，導致藥物過量釋放。此外，禁止按摩部位以防藥物短時間內大量吸收引發低血壓。
Application sites for transdermal nitroglycerin patches should be rotated to prevent skin irritation and maintain consistent drug absorption. The patch must never be cut, as this compromises the controlled-release mechanism, and massaging the site should be avoided to prevent rapid absorption and hypotension.
