Abstract Buffered solid dosage forms containing aspirin, magnesium hydroxide, and aluminum hydroxide are blended with acidic ethanol to extract the aspirin and salicylic acid rapidly. The resulting preparation is then immediately injected onto a 4.6 mm x 3 cm 5 (im reverse-phase column. Aspirin and free salicylic acid are determined simultaneously. The run time is <2 min. The total time from the initiation of sample extraction to completion of the separation is <5 min.

Objective: An easy, perfect, specific and exact process has been studied for the simultaneous estimation of Glimepiride pure drug form as well as tablet dosage forms. Methods: A UV method for quantitative evaluation of Glimepiride by first order derivative peak detect method for determination in bulk as well as tablet dosage form is reported as there was a need to expand novel methods to analyze the drug. Results: Glimepiride has absorbance first derivative maxima at 225 nm in Methanol. Glimepiride follows Beer’s law in concentration range of 5-25µg/ml. The outcomes of the study were validated statistically and recovery studies were performed as per ICH guide lines. Conclusion: Thus the projected method can be applied competently for the estimation of Glimepiride in regular analysis in its dosage forms.
