    Background In Thailand and the US negotiating FTA, the 'TRIPs-Plus' is one of the US proposal which would result in an extension of market exclusivity of innovative drugs. In addition, it would foreseeably lead to high and unaffordable medicine prices and inaccessibility to essential medicines.Objective To quantify the impact on medicine expense and medicine accessibility.Methods Based on 2000 to 2003 Thai Food and Drug Administration (FDA)'s and the Drug & Medical Supply Information Center (DMSIC), costs and accessibility were estimated upon the price and quantity costing between innovative drugs and their generics plus some parameters found from their competitive behaviour. Thereafter, we simulated the 10-year potential additional expense on the 2003 unit price of the patented and monopolized non-patented medicines.Results In 2003, the availability of generics helped to save 104.5% of actual expense and the accessibility would increase by 53.6%. By extension of market exclusivity, given that there were 60 new items approved annually, the cumulative potential expense was projected to be $US 6.2 million for the first year to $US 5215.8 million in tenth year.Conclusion The TRIPs-Plus proposal would result in a significant increase in the medicine expense; and a delay in the increase in drug accessibility via generics. Several options as well as other related mechanisms to help reduce the negative impact are proposed.
