title: Stability of four commercial products delivered by mail order.
abstract: The purpose of this study was to investigate the stability of four commercial tablets commonly shipped via mail-order delivery. The products were: enalapril maleate 10-mg tablets, digoxin 0.25-mg tablets, clorazepate dipotassium 7.5 mg-tablets, and pyridostigmine bromide 60-mg tablets. The stability studies were conducted at 50 deg C, and tablets were exposed for three, seven and 14 days to that temperature. The results demonstrated that all tablets studied were stable in these conditions for their exposure time. Therefore, it appears that all the tablets remained stable and could be used with confidence in mail-order delivery provided the original product packaging is not compromised.
