The aim of this study was to investigate how the different excipients influenced the chemical stability of betamethasone dipropionate in creams. The chemical stability was evaluated by analyzing betamethasone related substance content. Transcutol is the excipient ensuring maximum stability to betamethasone. Incompatibilities between betamethasone dipropionate and hexylene glycol were observed. The pH values in the weak acid range confer chemical stability to betamethasone.
