Estimation of creatinine clearance (Clcr) has long been a problem in critically ill patients with unstable kidney function. The commonly used methods like the Cockcroft-Gault method require a stable kidney function. A reliable and more accurate tool is needed to estimate Clcrto to guide drug dosage adjustment. The study aimed to compare the eight methods to estimate Clcr with measured Clcr. In addition, the study also aimed to determine the agreement between estimated Clcr with measured Clcr. This was a multicentre, prospective, observational study. Three intensive care units in Malaysia tertiary public hospitals. Two serum creatinine samples over 24 hours apart and simultaneously 24 hours urine collection. A total of 43 patients were recruited. During the early phase of unstable kidney functions (regardless of acute deteriorating or acute improving), only the modified Cockcroft-Gault method showed a non-significant different with the measured Clcr (p = 0.741). A sub-set analysis on 23 patients with acute deteriorating kidney functions was performed. Only the modified Cockcroft-Gault revealed a non-significant different with the measured...

Natural plant-derived compounds have been an essential resource in the evolution of drug discovery since the dawn of time. Using plants as a source of medicine is a century-long-standing tradition not merely in India but also in the entire world. North-East India is bestowed with incredible biological richness. The current research is focused on the histological and phytochemical analysis of four potent plant species collected from Goalpara district of Assam that is widely used in treating skin disorders. The four medicinal plants were collected based on traditional knowledge. The plants were evaluated for the identification and histochemical localization of effective phytochemicals following the standard protocols. Qualitative phytochemical analysis revealed the presence of important phytoconstituents responsible for different biological activities, including dermal activity. The histological study further showed the localization of phytochemicals, alkaloids, terpenoids, tannins, phenolics and flavonoids in all four plants. From adults to neonates, skin disorders are a major problem, especially in developing countries. Dermatological problems often deal with costly medications. The present study indicates that the studied...

Current work makes known that Liquid Chromatography-Mass Spectrometry (LC-MS) method development and validation for the impurity G (N, N -dimethylpyridin-4-amine) and impurity S (2-[(2-amino-6-oxo-1,6-dihydro-9H-purin-9-yl) methoxy] ethyl N-[1,1-dimetylethoxy) carbonyl]-L-valinate) in Valaciclovir Hydrochloride Hydrate active pharmaceutical ingredient (API). The developed LC-MS analytical method is complimentary to the thin layer chromatography (TLC) method available for impurity G and impurity S quantitation in the Valaciclovir Hydrochloride Hydrate API monograph. Impurity G and Impurity S were determined by the LC-MS method in Q1 Multiple ion mode using Ascentis Express C18 (15cm X 4.6 mm) 2.7µm analytical HPLC column. A gradient system was employed for the elution of analytes using acetonitrile (Eluent B) and 0.01M Ammonium Formate, LC-MS compatible volatile buffer, pH 3.0 (Eluent A) in distinct compositions. The gradient system (T/%B) was applied as 0.01/5, 4.00/5, 7.50/80, 10.00/80, 12.50/5, and 20.00/5. A method developed was validated considering the International Conference on Harmonization pharmaceutical guidelines. The quantitation limit found for Impurity G and Impurity S were 207.20ppm and 216.00...

Glibenclamide belongs to a group of medicines called sulfonylureas. Glibenclamide is used to manage diabetes. Glibenclamide, also known as glyburide, is an antidiabetic medication used to treat type 2 diabetes. The purpose of the present study was to formulate an Oral dispersible tablet of Glibenclamide using the Solid dispersion technique through using polyethylene glycol ratio as a water-soluble carrier. The solid dispersion of Glibenclamide was prepared by using fusion methods. The characterization of Glibeclamide solid dispersion powder was done by using several parameters like bulk density, tapped density, Carr’s Index, Hausners’s ratio, drug content, solubility and in-vitro dissolution study. While the oral dispersible tablet was prepared by using direct compression method. The prepared tablets were evaluated for disintegration time, moisture content, friability, and wetting time. From this study, it can be concluded that fast disintegrating tablets could be a potential drug delivery technology for managing diabetic...

Purpose: The present study has been designed to investigate the protective effect of methanolic extract of Albizia odoratissima (AO) bark in prevention of streptozotocin (STZ) induced-diabetic nephropathy (DN) in Wistar rats. Methods: Healthy Wistar rats of either sex weighing 180-200g were employed in the present study. Experimental diabetes was induced in rats by injecting STZ at a dose of 45 mg/kg (i.p.). Assessment of DN was done by estimating glucose level in blood and urine samples. Moreover, different antioxidant parameters like catalase, superoxide dismutase (SOD) and thiobarbituric acid reactive substances (TBARS) in kidney tissue samples were assessed. Additionally, inflammatory cytokines like interleukin-1 (IL-1), transforming growth factor beta (TGF-β), and tumour necrosis factor-alpha (TNF-α) were assessed in renal tissue. Results: Methanolic extract of AO bark (AOB) has shown significant prevention against diabetes-associated nephropathy. The bark extract decreased glucose levels both in urine and blood sample. The AO extract, either alone or in combination with a standard drug (glibenclamide) showed a significant reduction in oxidative stress in renal tissue, as demonstrated...
