Development of RP-HPLC Method of Tizanidine HCL with Some Validation Parameter.

This study compiles the information for the development of analytical methods for estimation of the Tizanidine HCl that will be helpful for further research work on this drug and its impurity. The present Literature survey provides information about the Analytical methods like UV,TLC,RP-HPLC,HPTLC,UHPLC and other methods have been reported for Tizanidine HCl drug individually and along with other drugs. The analysis of published data revealed that, there was only UV spectroscopic method (calibration curve metod) is reported for estimation of Tizanidine HCl fixed dose combination. Estimation of Tizanidine HCl by superlative RP-HPLC method i.e. Mobile phase- Acetonitrile: phosphate buffer (pH: 7.5) (50:50%v/v), Column C18 (250mm*4mm*5µm), Flow rate- 1.0 ml/min, Wavelength: 318 nm. Optimized HPLC condition was validated by assessing validation parameters and it meet the acceptance criteria set by ICH. It was showed method was linear and precise. The validated RP-HPLC-PDA method can be used for routine analysis of Tizanidine HCl in tablet.

Formulation and Evaluation of Drumstick Leaves Tablet as An Immunomodulator.

The human immune system plays a pivotal role in protecting the body against pathogens, maintaining homeostasis, and preventing disease. Immunomodulation, the process of regulating immune responses, is crucial for optimal health. In recent years, there has been growing interest in natural remedies for immune system modulation, driven by the recognition of their potential efficacy and safety profiles. This project aims to investigate the immunomodulatory effects of drumstick leaves tablets, derived from Moringa oleifera, a plant known for its rich nutritional and medicinal properties. The study will explore the potential of drumstick leaves tablets to modulate immune responses through in vitro and in vivo experiments. Through comprehensive analysis of the immunomodulatory properties of drumstick leaves tablets, this project aims to contribute to our understanding of natural remedies for immune system modulation. The findings could have significant implications for the development of novel therapeutic interventions aimed at enhancing immune function and improving human health.

Central Composite Design Expert-Supported RP-HPLC Optimization and Quantitative Evaluation of Efonidipine Hydrochloride Ethanolate & Chlorthalidone in Tablet.

Central composite design based RP-HPLC method optimization for the synchronized analysis of Efonidipine Hydrochloride Ethanolate (EFE) and Chlorthalidone (CHL) in tablet. The effective separation was performed using Inertsil ODS C18 column (250 × 4.6 mm, 5 µm), PDA detector with 0.05 M KH2PO4 Buffer (pH 4.5): Acetonitrile (40:60%v/v) mobile phase. Independent variables were investigated include the concentration of KH2PO4 (X1) and flow rate of mobile phase (X2). Based on responses obtained (retention time, resolution and tailing factor), the optimum condition selected was X1 = 40% and X2 = 1 ml/min. Optimized HPLC condition was validated by assessing validation parameters and it meets the acceptance criteria set by ICH. The linear calibration curve was found to be in the quantity range 6.25-18.75 and 20-60 µg/ml Assay of drugs was 100.94 and 100.06% for CHL and EFE. The validated RP-HPLC-PDA method can be used for routine analysis of EFE and CHL in tablet.
