The aim of this study was to develop a palm kernel-based emulgel containing Mitracarpus scarber and examine the product's physicochemical characteristics and anti-inflammatory efficacy on Wister rats. Different batches of emulgel comprising Mitracarpus scarber leaf extracts (MSE), different proportions of oils (palm kernel oil and/or liquid paraffin), and surfactants (tween-80 and/or Cremophor EL-30) were prepared. The freshly prepared and 5-month-old formulations, stored at room temperature (28 ± 2 °C), were evaluated for rheology, syneresis, and extract/excipient compatibility using Fourier transform infrared (FT-IR) spectroscopy. The spreadability, extrudability, and anti-inflammatory activity of the optimal formulation were compared with those of a commercial anti-inflammatory emulgel. Even after five months of storage, the created emulgels remained olive green and creamy, with a homogeneous texture, consistency, and glossy appearance. The optimized batch containing palm kernel oil, tween-80, and xanthan gum had the most stable characteristics, with no significant change in pH (P = 1.000) or FT-IR spectrum after 5 months of storage. It exhibited spreadability and extrudability of 12.75 cm2 and 600 g/cm2, respectively, compared to 16.82 cm2 and 400 g/cm2 for the commercial formulation. Four hours post-treatment, the anti-inflammatory effect of the optimized batch was significantly (P < 0.05) higher than that of the aqueous MSE dispersion. The obtained results demonstrate the prospects of palm kernel-based emulgel loaded with Mitracarpus scarber leaf extracts as an innovative therapeutic approach to inflammation treatment.

The extraction process was carried out using water and the mucilage was characterized using various physicochemical and rheological parameters. All confirmatory tests for mucilage carried out (Molisch, iodine and ruthenium red test) were positive. The outcomes demonstrated that the mucilage had a yield of 52.6 %, a swelling capacity of 88.65 %, hydration capacity of 1.78 and a viscosity of 1.1805 mPa S. This study highlights the importance of utilizing natural resources for sustainable development and provides insights for further research on the potential uses of mucilage from other plant sources.

Methods: Different batches of emulgel comprising different proportions of oils (sesame oil and/or Labrafac CC), surfactants (Tween-80 and/or cremophor EL-30), and gelling agents (xanthan gum or gelatin) were prepared. The formulations were evaluated for rheology, syneresis, Fourier transform infrared (FTIR) spectroscopy, spreadability, extrudability, and anti-inflammatory activity. Results: Product characteristics of batches A2, A4, and A6 were not consistent with those of emulgels. Because Batch A1 showed characteristics that were the most stable, such as no pH changes, nonstatistically significant changes (p = 1.000) in the viscosity results, and least spectrum changes following FTIR investigation, it was selected as the best batch. It showed similar anti-inflammatory activity when compared with commercially available diclofenac emulgel, giving a 50 % higher anti-inflam...

Objectives: The work aimed to evaluate the disintegrant property of sorghum starch-silicon dioxide co-processed mixture in the formulation of chlorpheniramine orodispersible tablets. Method: Different batches of orodispersible tablets of chlorpheniramine maleate (4 mg) were prepared by direct compression method using Avicel® as a bulking agent and four different types of disintegrants (sorghum starch, co-processed sorghum starch-colloidal silicon dioxide, sodium starch glycolate and croscarmellose sodium) at varying concentrations (5, 10 and 20 %). The formulated tablets were subjected to weight variation test, thickness, crushing strength, friability test, wetting time, water absorption ratio, disintegration test and in-vitro dissolution study. Results: For tablets above 250 mg, it is expected that not more than two tablets should deviate from the average weight by 5% and none should deviate by more than 10%, all the formulations yielded tablets within this specification. The disintegration time of tablets containing 10% of disintegrants was all less than 60 s except those containing sorghum starch (SS) which took a long time. Similarly, the time taken to release 50 % of the drug (t50%) for tablets containing 10% sorghum starch was 25 s, 5 s for tablets containing 10% sorghum starch-colloidal silicon dioxide excipient and 8 s for tablets containing 10% of either croscarmellose sodium or sodium starch glycolate. The differential scanning calorimetry study results suggested that the drug and the excipient are compatible. Conclusion: The results show that sorghum starch-silicon dioxide co-processed mixture can be used as an alternative to croscarmellose sodium and sodium starch glycolate in orodispersible tablet formulations.

However, the conventional dosage form has few limitations which could be resolved by modifying the existing dosage form. Sustained and controlled drug delivery systems help to maintain constant plasma drug concentration and retarding the release rate of drug thereby extending the duration of action. Objectives: To develop by co-processing technique a two-component excipient and evaluate its sustained release potential in ibuprofen tablet formulation. Method: Maize starch (MS) was co-processed with polyvinylpyrrolidone (PVP), acacia powder (ACA) and hydroxypropyl methylcellulose (HPMC) respectively at a ratio of 60:40 using the co-fusion method. The granules so formed were analyzed for flow properties and compatibility tests based on; angle of repose, flow rate, bulk and tapped densities (BD/TD), Hausner ratio (HR) and Carr’s Index (CI), Differential Scanning Calorimetry (DSC)...

Methods and Materials: Metronidazole suspension was formulated with mucilage (0.1%, 0.5%, 1%, and 2% w/v) from P. biglobosa seeds as the suspending agent. Similar suspensions of metronidazole that contained (0.1%, 0.5%, 1%, and 2% w/v) tragacanth or gelatin were also prepared for comparison to PBM-based formulations. The suspensions were assessed for rheological properties, sedimentation volume, degree of flocculation, ease of redispersion, flow rate (flowability), and drug-excipient compatibility using Fourier-transform infrared spectroscopy. Results: Brownish metronidazole suspensions with a smooth and elegant appearance were obtained. After 2 weeks of storage at ambient temperature (28 ± 2°C), the ease of redispersion was in the following order: tragacanth < PBM < gelatin-containing formulations.

The most common source of commercial microcrystalline cellulose is fibrous wood pulp. Cellulose and its derivatives have found wide commercial applications in the pharmaceutical, cosmetic, food, paper, textile, and engineering industries. This study aims to isolate and characterize cellulose forms from cocoa pod husk (CPH) and to assess its mechanical and disintegration properties as a direct compression excipient in metronidazole tablets. Two isolated cellulose types (i.e., cocoa alpha-cellulose (CAC) and cocoa microcrystalline cellulose (C-MCC)) were compared with avicel (AV). CAC and C-MCC were characterized for their physicochemical properties using Scanning Electron Microscopy (SEM), FTIR spectroscopy, Differential Scanning Calorimetry (DSC), and X-Ray Powder Diffraction (XRD).
