Abstract: A dispensing apparatus comprising a case (20) and a removable package (10), for example a blister pack. The package (10) has compartments (12) and a film (11) of frangible material extending across the mouth of the compartments (12) in order to close the compartments (12). An electrically conductive track (16) is provided on the external face of the film (11) and has segments that traverse at least partly across the compartments (12). The case (20) includes a connector (22) for receiving the package (10) and means for electrically connecting, when the package (10) is inserted, the conductive track (16) to a monitoring system located in the case (20). The monitoring system includes means for monitoring the electrical signals from the conductive track, and means for determining that a respective compartment (12) has been opened upon depending on the monitored electrical signals.
