The in vivo anti-cancer activity of Syringodium isoetifolium against DEN-induced hepatocellular carcinoma in Wistar albino rats is described in this work for the first time. Materials and methods: Wistar albino rats were used as test subjects to examine the anti-cancer properties of Syringodium isoetifolium against DEN-induced hepatocellular carcinoma at the dose of 50 mg/kg body weight. The experimental rats were split into five groups (Group I-V). Except for group I, remaining all animals received DEN and Phenobarbitone during the experiment. Group I and Group II acted as normal and diseased control groups respectively. The extracts were administered to the satellite group III and IV orally with the dose of 250 and 500 mg/kg body weight respectively. 5 fluorouracil 20mg/ kg was administered to group V orally and considered as a standard. The total experimental period lasted for 14 weeks. Results: The findings show that Syringodium isoetifolium significantly reduces liver tumor volume, burden and numbers in experimental rats ( p <0.05) when compared to the control group. Besides, the extracts treated groups restored the pathological parameters close to normal values ( p <0.05). The histological analysis also showed that the extract-treated animals' livers had recovered their normal architecture.

The combination of commonly accessible natural polysaccharides like gum may provide a new arrangement of dosage forms such as polyelectrolyte complex. Such modern improvements facilitate the modulated release of active, which can be beneficial in avoiding adverse consequences. There have been no reports on chitosan and sesbania gum-based polyelectrolyte complexes for drug delivery applications to date. Objectives: The chitosan-sesbania gum polyelectrolyte complex was developed for modified drug delivery of diclofenac sodium. Materials and Methods: pH-responsive polyelectrolyte complexes were accomplished utilizing the coacervation technique. It forms complex due to the capability of chitosan amine groups and sesbania gum carboxylic functionality. Results: The SEM analysis assured the aggregated polyhedral shape particles with a smooth surface of the final polyelectrolyte complex. The Diffractogram of the polyelectrolyte complex resulted in an amorphous form of diclofenac. The polyelectrolyte complex batch (B:3) showed satisfactory drug entrapment capabilities. It showed 88.96% of the drug release in 8 hr (pH 6.8). Importantly, it is because of the unprotonated condition of sesbania gum containing hydrophilic functionality that offers boosted hydrogen bonding via interaction with dissolution medium containing water molecules. Therefore, it offers the insertion of water molecules into a complex followed by the swelling of a matrix. Conclusion: The developed chitosan-sesbania gum polyelectrolyte complex offers a pH-responsive sustained release of diclofenac sodium. In the future, chitosan and sesbania gum-based polyelectrolyte complex can be preferred as an innovative drug carrier for diclofenac sodium delivery.","PeriodicalId":13407,"journal":{"name":"Indian Journal of Pharmaceutical Education and Research","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47125425","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objectives: To enhance the solubility of Raltegravir potassium and its free acid using Soluplus ® by solid dispersion technology. Materials and Methods: In the current study, Amorphous Solid Dispersions (ASDs) of RTGP and Raltegravir free acid (RTG) of 20:80% w/w with Soluplus ® (SLP) were prepared using quench cooling. The prepared ASDs analyzed for homogenous single-phase formation and intermolecular interactions employing DSC, XRD, and FT-IR. The drug-polymer miscibility was calculated theoretically as well as experimentally with the aid of Hansen solubility parameter and melting point depression methods. The solubility of the ASDs was evaluated by the shake flask method. Results: Quench cooling yielded an RTGP-SLP and RTG-SLP homogeneous amorphous systems. DSC and XRPD results showed the complete transformation of crystalline to the amorphous phase for ASDs. Intermolecular interactions in specific hydrogen bonding were observed between the carbonyl (-C=O) group of Soluplus ® and the Raltegravir -N-H moiety. RTG solubility in salt solid dispersion increases by 10.7 and 17.4 folds, respectively, compared to pure forms.

Materials and Methods: Luliconazole, an anti-fungal agent used in the treatment of fungal infection, was successfully formulated as niosomal topical gel by using a polymer carbopol 934. The 3 2 full factorial statistical design was employed as a means for the optimization of niosomal formulation to check the impact of two formulation factors namely, concentration of cholesterol and span 60 on two dependent variables % drug release and % drug entrapment efficiency in formulated niosomal formulations. Results: The mean vesicular size, Zeta potential, drug release and entrapment efficiency of optimized formulation was found 150.6 ± 11.1 nm, -23.5 ± 5.08, 92.41 ± 2.44% and 92.36 ± 2.85%, respectively. The scanning electron microscopy study reveals that the optimized formulation was spherical, porous and rough in surface. The thermogram of differential scanning calorimetry study states that the drug may be solubilise or converted to amorphous form in niosomal vesicles. The viscosity and spreadability of niosomal gel were observed satisfactorily for the easy topical application. The ex vivo study of optimized niosomal gel showed significant higher drug release (97.31 ± 3.18%) in comparison with marketed product (82.20 ± 1.95%).
