FORMULATION, OPTIMIZATION, CHARACTERIZATION AND IN VIVO ANTI-ULCER ACTIVITY OF ESOMEPRAZOLE MAGNESIUM TRIHYDRATE GASTRORESISTANT MICROSPHERES

Objective: The objective of the present investigation was to prepare gastro-resistant microspheres of esomeprazole magnesium trihydrate (EMT) to prevent its degradation in the acidic environment of the stomach and enhance its bioavailability via intestinal absorption.Methods: EMT loaded gastro-resistant microspheres were prepared using hypromellose acetate succinate (HPMCAS) as the gastro-resistant polymer by ‘non-aqueous solvent evaporation' technique. A 3-factor 3 level factorial design was used to optimise EMT: HPMCAS ratio, the concentration of Span 80 and stirring speed with respect to percent entrapment efficiency and particle size. Further characterization was carried out using scanning electron microscopy (SEM), differential scanning calorimetry (DSC), In vitro release study and In vivo anti-ulcer activity.Results: Fourier transform infrared (FTIR) study indicated compatibility between drug and polymer. DSC study revealed that the drug was molecularly dispersed in the polymer. The optimised batch showed 49.63±1.23% drug entrapment and 170.12±3.36 μm particle size. SEM study showed that microspheres were spherical in shape. In vitro drug release study showed only 4.28±1.23% drug release in simulated gastric media in 2 hr and 93.46±1.20% release in simulated intestinal media after 1 hr from the optimised batch.Conclusion: Results of in vitro release studies indicated the gastro-resistant nature of the developed microspheres. In vivo anti-ulcer activity demonstrated that EMT loaded microspheres were able to significantly reduce ethanol-induced ulcer formation in rats' stomach as compared to the aqueous solution of EMT. So it can be concluded that the developed gastro-resistant microspheres of EMT prevented drug release in the stomach which would lead to a significant improvement in its bioavailability through enhanced intestinal absorptio

Evaluation of Antioxidant Activity of Cedrela toona Roxb. Leaf Extracts

Antioxidant potency of fruits of Cedrela toona Roxb. crude methanol and its fractionated extracts (hexane, acetone and water) have been investigated, employing three different established in vitro testing systems, such as scavenging activity on 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals, reducing power assay and β-carotene method. The methanol extract of fruits of Cedrela toona Roxb. showed the best DPPH scavenging activity with the lowest EC 50 34 μg/ml, followed by the acetone (EC 50 39 μg/ml), hexane (EC 50 48 μg/ml) and water extract (EC 50 54 μg/ml). The reducing power of Cedrela toona Roxb. fruit extracts increased steadily with increasing concentrations and varied significantly with different concentrations. The methanol and acetone extracts appeared to possess the highest significant reducing activity among the extracts. The stronger reducing power in the methanol and acetone extracts was probably due to the concentration of antioxidant compounds like flavonoids and phenolics in the extract. In the β-carotene bleaching assay, the antioxidant activities of all the fruits extracts gradually increased with increasing concentration of the extracts and varied significantly with different concentrations. The water extract showed the lowest significant antioxidant activity, while the methanol extract showed the highest significant antioxidant activity. The high antioxidant activity of methanol extract tested using β-carotene model may be correlated with the high phenolic content of the methanol extract.  In conclusion, antioxidant study suggested that fruits of Cedrela toona Roxb. are potential source of natural antioxidants. However, further investigations on in vivo antioxidant activities are highly recommended. In the present study, the antioxidant potency of Cedrela toona Roxb. crude methanol and its fractionated extracts (hexane, acetone and water) have been investigated, employing three different established in vitro testing systems, such as scavenging activity on 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals, reducing power assay and β-carotene method. There is no antioxidant study reported for Cedrela toona Roxb.Thus, antioxidant activity of Cedrela toona Roxb. was evaluated as it had not been determined previously

Perinatal and maternal outcome in meconium stained amnioticfluid (thin and thick) at dhiraj general hospital, a rural tertiary health centre

Background: To determine the perinatal outcome of with Meconium-stained amniotic fluid (MSAF) compared with clear amniotic fluid at Dhiraj Hospital.Methods: A prospective observational study was carried out in obstetrics and gynaecology department of Dhiraj Hospital, Sumandeep Vidyapeeth from March 2021 to August 2021. All patients fulfilling inclusion and exclusion criteria as mentioned above were taken for the study. All the categorial variables were analysed independently with the help of chi square test and fisher’s exact test and all the continuous variables were analysed with independent ‘t test’.Results: Out of 500 patients selected for the present study which had inclusion criteria, 13.6% were meconium stained out of which 50 (73.5%) cases had thin meconium and 18 (26.4%) cases had thick meconium. Fetal CTG abnormalities were more common in MSAF group and were noted in 38.2% of cases which is significantly increased compared to control group with CTG abnormalities in 8.3%. The difference was significant with p value of <0.001. 32(47.0%) patients with meconium-stained amniotic fluid had normal vaginal delivery, while in control group out of 432, 360 (83.3%) delivered normally. Incidence of LSCS and assisted vaginal delivery was more in meconium-stained amniotic fluid.Conclusions: Meconium-stained amniotic fluid is associated with more frequency of operative delivery, birth asphyxia, neonatal sepsis, and neonatal intensive care unit admissions compared to clear amniotic fluid. Better perinatal outcome in clear amniotic fluid compared to meconium stained liquor
