Abstract: A system for controlling the distribution of pharmaceuticals involves tracking the distribution of pharmaceutical products and managing pharmaceutical rebates via the internet. The system provides for the verification, payment and auditing of the rebates. Before the pharmacy can participate in the rebate scheme they must first undergo an initial registration process 110. Following registration, the pharmacy may purchase pharmaceutical products which are supplied from the manufacturer via a supply chain 120. The pharmaceuticals are supplied at a standard supply price, irrespective of the country in which the retailers are located. When the pharmaceuticals are supplied to an end user, e.g. a patient, the pharmacy enters a rebate claim 130, which is processed by an international clearing centre 140. Provided the processing has a successful outcome, the pharmacy receives a rebate payment 150, the size of which depends upon the country in which the pharmacist is located.
