The document describes the formulation and evaluation of mouth dissolving tablets containing the drug mirtazapine. Six formulations of mirtazapine mouth dissolving tablets (F1-F6) were prepared by wet granulation method and evaluated for properties such as thickness, hardness, friability, drug content and in vitro drug release. Formulation F6 was found to have the desired drug release profile, with 99.16% of the drug releasing within 20 seconds. Stability studies showed that F6 remained stable for 1 month at 45°C. It was concluded that F6 is the optimized formulation for a 20 second dissolving mouth dissolving tablet of mirtazapine.
