A simple UV-Vis Spectrophometric method was developed for the simultaneous determination of salbutamol sulphate and ambroxol HCl (AMB) from their combined dosage form. The method employs formation and solving of simultaneous equation using 242 nm and 272 nm as two analytical wavelengths (λMax of the drugs) of detection. Both the drugs obeyed Beer-Lambert’s law over the concentration range 1-50 μg/mL for salbutamol sulphate and 10-50 μg/mL for ambroxol HCl, respectively. The developed method was validated for Accuracy, Precision, Limit of Detection and Limit of Quantification as per ICH guidelines and results of analysis were validated statistically.

A new simple, reproducible and efficient liquid chromatographic method (RP-HPLC) was developed for simultaneous estimation of thiocolchicoside and etoricoxib for tablet formulation. Formulation containing thiocolchicoside and etoricoxib is used as analgesic. Separation was achieved by Nucleosil (4.6mm I.D × 250 mm) C18 column with mobile phase consist of Acetonitrile: water (0.05% Orthophosphoric acid V/V) in the ratio 25:75 at flow rate 0.7ml . The detection was carried out at 220nm. The retention time of thiocolchicoside and etoricoxib was found to be 3.75 min and 6.13 min respectively. Linearity of THC and ETR was found to be in the range of 2-10µg/mL and 30-150µg/mL. Percent recovery obtained for THC and ETR were 99.98% and 99.69% respectively. The method was validated as per ICH guidelines.

Cancer has been one among the main threats to the lives of citizenry for hundreds of years. Traditional drug therapy has certain defects such as poor targeting, easy degradation, high side effects, etc. Therefore, to enhance the treatment efficiency of anticancer agents, there is need of developing new drug delivery systems. Black phosphorus is a member of the 2D family, and it possess the potential to construct drug delivery system by virtue of its photothermal therapy, photodynamic therapy, and biodegradable properties. Due to their special structure BP are considered to be the best platform for drug delivery. They have shown large potential as near-infrared photothermal therapy agents and drug delivery for cancer therapy. The present review covered advances in BP- based drug delivery system along with its advantages and applications in cancer therapy.
