چکیده انگلیسی
A study was carried out to investigate compatibility of atenolol, a β1 blocker, with a variety of pharmaceutical excipients. The binary mixtures (1:1) of atenolol with the excipients were stored for 1 month at 40 °C/75% RH. The samples were directly observed for the physical changes, and also analyzed by a validated HPLC method to determine the chemical changes. The study revealed that atenolol was incompatible with ascorbic acid, citric acid and butylated hydroxyanisole. The degradation/interaction products formed in these mixtures were characterized by high resolution mass spectrometric and fragmentation analyses, using a LC–MS/TOF system. The identity of characterized structures was justified through mechanistic explanations.
