The objective of this study is to compare the rate and extent of absorption of two Tramadol Contramid® OAD 300 mg controlled-release tablets from two different manufacturing sites, administered as 1 x 300 mg controlled-release tablet under fasting conditions. The effect of food on the to-be-marketed formulation was also assessed.
