Abstract

A high performance liquid chromatography method has been developed and validated method for the simultaneous estimation of Montelukast sodium in bulk and tablet dosage form. The method was carried out using Princeton SPHER ULTIMA C18 100A 5μ 250*4.6 mm using OPA: Methanol (10:90 v/v) as mobile phase at flow rate 1ml/min. HPLC separation was carried out at 284 nm. The linear regression analysis data for the calibration plots showed good linear relationship with r² = 0.9982 and 0.9979 for Montelukast sodium in bulk and tablet dosage form respectively in the concentration range of 1-6 μl/ml for Montelukast sodium in bulk and tablet dosage form. The method was validated for precision, robustness, specificity and accuracy. The limit of detection and quantitation were 0.0011 and 0.0033 μg/ml. the proposed HPLC method can be applied for identification and quantitative determination of Montelukast sodium in bulk and tablet dosage form.

Abstract

The aim of present work research work was formulation and evaluation of stable montelukast sodium sublingual tablet. Since The thermal stress testing study of Monte in solutions at 65°C showed that it is highly stable in NaOH solution, while it degrades rapidly in both acidic and H₂O₂ solutions. Hence lyophilization technology was adopted to increase the stability of montelukast sodium. Before lyophilization three trials were carried out to optimize the process parameters in which Trial 2 was considered as optimized process. The Lyophilization was carried out in nine different batches by varying the total cycle time, freezing and holding time, primary drying and secondary drying time by maintaining the quantities of all the active pharmaceutical ingredients constant and selection of cryoprotectant ratio. An optimized lyophilization cycle of 56 hours has been achieved. The optimized lyophilized product was subjected to Tablet compression. In this process the batch-9 formulation was considered as an optimized Formulation for compression with the process. All the in-vitro evaluation parameters complies the limits as per the specification. Stability studies were conducted and from the result it was concluded that the optimized formulation was found to be stable. Finally, it is concluded that the lyophilization is a suitable technique to increase the stability and bioavailability of Montelukast sodium.
