The prevalence of counterfeit drugs is on the rise in a large number of countries, including Thailand. To help deal with these chal­lenges, a Memorandum of Under­standing (MoU) was signed on Febru­ary 14, 2008, initiating “Operation to Prevent and Suppress Drugs Violating Intellectual Property.” The signatories to the MoU include the Department of Intellectual Property, the Customs Department, the Royal Thai Police, the Department of Special Investigation, and the Pharma­ceutical Research and Manufacturers Association. The main aim of this MoU is to coordinate the prevention and suppression of these counterfeit drugs, as well as to protect customers.
