To the editor: Many patients in our general medical clinic taking nitroglycerin ointment have returned between their regularly scheduled appointments for refills. As this need may affect medication-taking compliance (1), we wonder whether clinicians know how many doses are available in a standard 60-g tube of 2% nitroglycerin ointment?
Ten samples of each of 1 inch (2.5 cm), 1½ inches (3.8 cm), and 2 inches (5.1 cm) of 2% nitroglycerin ointment (Nitrol Ointment; Kremers-Urban Company, Milwaukee, Wisconsin) were measured on the Applirulers (Kremers-Urban Company) supplied with the tube. Each Appliruler was weighed so that the net weight could be calculated.
