Sixty-five patients with angina pectoris participated in a two-week, randomized, crossover, open-label, multicenter trial to compare patient preferences between two transdermal nitroglycerin delivery systems: Minitran and Nitro-Dur II (ND II). Patients were enrolled if they had stable angina pectoris and had been on a stabilized dose (5, 10, or 15 mg/24 hr) of Transderm-Nitro (TDN) for at least one month before entering the study. Patients with a bias against ND II or with any of the contraindications for transdermal nitroglycerin therapy were excluded. During the first one-week treatment period, the patients received their prestudy dose regimen of either Minitran or ND II. During the second week, the patients were crossed over to the transdermal delivery system that they had not received in the first week. Patients completed daily diaries, weekly questionnaires, and poststudy patient preference evaluation forms. Two patients, one in each treatment group, withdrew from the study because of increased angina, which was probably not related to the use of transdermal nitroglycerin. Fifty-seven percent of the patients preferred Minitran overall (P less than or equal to 0.05), 27% preferred ND II, and 16% had no overall preference. |
