2024-07-14 22:23:51 Keywords Bilastine, Montelukast sodium, ,
Development of a green synchronous spectrofluorimetric technique for simultaneous determination of Montelukast Sodium and Bilastine in Pharmaceutical Formulations
For the treatment of rhinitis and asthma, a combination of Montelukast sodium and Bilastine has just been approved. Based on the first derivative of synchronous fluorescence, the current work developed a green, highly accurate, sensitive, and selective spectroscopic approach for estimating Montelukast sodium and Bilastine in pharmaceutical dosage form without previous separation. The selected technique focuses on measuring the synchronized ... Read more

Utility of dansyl chloride for the establishment of a sensitive spectrofluorimetric approach for estimating midodrine hydrochloride: application to content uniformity testing
A new, straightforward spectrofluorimetric approach with high sensitivity was established for determining midodrine hydrochloride based on derivatizing this drug through its reaction with 5- (dimethylamino)naphthalene-1-sulfonyl chloride (dansyl chloride). The highly fluorescent product was extracted with methylene chloride, and then its emission was measured at 532 nm after excitation at 339 nm. The reaction was conducted in aqueous medium containing 0.1 ... Read more

Validated spectrofluorimetric and resonance Rayleigh scattering methods for determining naftidrofuryl in varied pharmaceutical samples based on its interaction with erythrosin B
Naftidrofuryl is a vasodilator medication used for treating cerebral and peripheral vascular diseases. In this study, two spectroscopical techniques, spectrofluorimetric and resonance Rayleigh scattering (RRS), were utilized to quantify naftidrofuryl in its pharmaceutical samples. The developed methodologies in this study rely on a facile process of forming an association complex between erythrosine B reagent and naftidrofuryl under acidic conditions. The ... Read more

Updates in the Pathogenesis of Alopecia Areata.
Alopecia areata is the most prevalent autoimmune disorder which causes non-scarring hair loss. It may increase the anxiety of patients and increase their chances of developing psychological and psychiatric disorders. There are two proposed theories for the pathogenesis of alopecia areata. The most evidence-based hypothesis is an autoimmune reaction caused by the collapse of hair follicle immune privilege, Immune privilege ... Read more

Bio-Stiumlants Extend Shelf Life and Maintain Quality of Okra Pods
Abstract Abstract Okra (Abelmoschus esculentus L.), a tropical annual crop, is a highly perishable vegetable. Okra pods deteriorate rapidly after harvesting. The pods undergo physical and physiological changes that diminish storability and quality. The purpose of this study was to investigate the effect of bio-stimulants on the storability and quality of okra pods stored at 4 °C and 25 °C ... Read more
