Objectives: Various analytical techniques are applied in pharmaceutical field to estimate the quality of active pharmaceutical ingredients, amount of drug in biological fluids and in formulations. The aim of this review article is to provide utmost existing analytical methods for analysis of dihydropyridines based calcium channel blockers for estimation of Amlodipine, Lacidipine, Isradipine, Nifedipine, Felodipine, and Cilnidipine in pure form, biological fluids (like Human Plasma, Human Serum, Human Urine etc.,) and its related formulations including novel formulations. Dihydropyridines based Calcium Channel blockers is a major chemical class of drugs used in the treatment of hypertension and various coronary artery diseases. Evidence acquisition: Current analytical techniques available for active pharmaceutical ingredients and its related formulations are tabulated with extensive method conditions which can be used in analysis of dihydropyridines based calcium channel blockers drugs outlined from official pharmacopoeias and other relevant research articles. Conclusion: Various analytical techniques such as HPLC, HPTLC, UPLC, GC, LC-MS, and GC-MS are involved. This review assists in appropriate selection of analytical technique, solvent, mobile phase, column, detector based on available analytical instruments and chemicals, by referring tabulated extensive method conditions. It can be implemented in quality control and quality assurance department for quality assessment of diverse pharmaceutical formulations.

This paper accomplishes an introduction to diverse types of vaccines against coronavirus. Many countries, researchers and pharmaceutical companies worked abundantly so that they could discover a safe and effective vaccine against COVID-19. In response to this, vaccines were discovered on a fast track mode and companies registered for an emergency use authorization, so that it would be helpful to society during pandemic. Manufacturers and various regulatory units are working tirelessly to develop, manufacture and deploy safe and effective vaccines. Scanty information is added on divergent COVID vaccines encompassing information related to the developer, vaccine class, description, efficacy rate, dosing, storage, permitted age groups and authorizations issued.

For the coincident evaluation of Dapagliflozin and Saxagliptin in bulk form; Chromatography was run through Intersil-ODS C18 column (250mm× 4.6mm, 5micron) Mobile phase containing Methanol: Water was pumped through the column in the ratio of 45: 55. The flow rate was 1ml/min. The temperature help was ambient i.e., upto300c. The optimized selected wavelength was 210nm. The retention time of Dapagliflozin and Saxagliptin was found to be 4.707min and6.68 min respectively. The %RSD of Dapagliflozin and Saxagliptin was found to be 0.031 and 0.036 respectively. The values of LOD and LOQ obtained from Dapagliflozin and Saxagliptin was 0.56, 1.69 and 0.57, 1.74 respectively. The retention time was decreased and the run time also decreased, so the method development was simple and economical that can be applied successfully for simultaneous estimation of combination of two anti- diabetic drugs; Dapagliflozin and Saxagliptin. KEY WORDS: Dapagliflozin and Saxagliptin, RP-HPLC.

Prednisolone is a widely used synthetic glucocorticoid drug used in the treatment of allergies, inflammatory conditions, auto-immune disorders, acute and chronic obstructive pulmonary disease, rheumatoid arthritis, systemic lupus erythematosus, dermatitis, eye inflammation, asthma and multiple sclerosis. A simple and economical method was developed using eco-friendly green solvent. In this developed method the eco-friendly green solvent used was ethanol which is available easily. The method was projected to quantitative estimation and assay of Prednisolone in Prednisolone dispersible tablet dosage form. The amount and percent label claim of Prednisolone in tablet dosage form was estimated using Beer-Lambert’s law. Specific absorbance (A1%1cm) of Prednisolone is 415 at lambda max of 243 nm. The method developed was validated as per ICH guidelines. The proposed method was found to be simple, accurate, sensitive, precise, linear and rugged. The method obeys Beer-Lambert’s Law in the concentration range of 2.5-20μg/mL, as the r2 value was found to be 1.000. The mean percent recovery was found to be within acceptable range as per ICH guidelines. Hence the developed method can be used in regular quantitative analysis. The developed method acquires only one green solvent, low cost analytical equipment and the percent label claim can be calculated in the assay of Prednisolone tablets without using any standards solution or standard graph by just employing specific absorbance value in Beer-Lambert’s law, thereby concentration of drug can be calculated. As this method is simple, economical and eco-friendly it can be used elegantly and routinely in analytical laboratories and industries for estimation of Prednisolone in tablet formulation.
