A dissolution method was developed and validated for evaluation of the dissolution behavior of capsule dosage form of tramadol hydrochloride as there was no official method available. The UV spectrophotometric method developed was based on the direct estimation method using 271 nm as λmax of tramadol hydrochloride. The method was validated according to International Conference on Harmonisation (ICH) guidelines which include accuracy, precision, specificity, linearity, and analytical range. In addition, solubility and stability of the drug in dissolution medium i.e., 0.1 N HCl was studied. The established dissolution conditions were 900 mL dissolution medium at temperature 37 ± 0.5°C, using USP apparatus I at stirring rate of 100 rpm for 30 min. The corresponding dissolution profiles were constructed and all the selected brands showed more than 80% drug release with in 30 min. Thus, the proposed dissolution method can be applied successfully for the quality control of tramadol hydrochloride capsules.
