ABSTRACT:
A moisture-retentive covering for ointment, such as nitroglycerin, applied for percutaneous absorption includes a flexible frame member having first and second surfaces with adhesive material thereon. A sheet of moisture-impervious material is secured to the first surface of the frame member and entirely covers the first surface and the area prescribed within the frame. A removable backing is secured to the second surface. A tab extends from the sheet of moisture-impervious material to permit the covering to be gripped while the removable backing is peeled away.
