Validated UV spectrophotometric method development and stability studies of Acamprosate calcium in bulk and tablet dosage form

A simple, rapid, accurate, precise, specific and economical spectrophotometric method for estimation of Acamprosate calcium in tablet dosage form has been developed. Beer-Lambert's law was followed in the concentration range of 10-50μg/ml (r²= 0. 999). LOD and LOQ were found to be 0. 3626μg/ml & 1. 0989μg/ml respectively. The result of percentage recoveryand placebo interference shows that the method was not affected by the presence of common excipients. Thepercentage assay ofAcamprosate calcium in tabletswas 99. 4%w/w. The method was validated by determining its sensitivity, accuracyand precision which proved suitability of the developed method for the routine estimation of Acamprosate calciumin solid dosage form and it was subjected to stress degradation under different conditions recommended by ICH.
