The purpose is to formulate the solid self emulsifying drug delivery system (S-SEDDS) to improve poor aqueous solubility and dissolution of ciprofloxacin. A solubility study was carried out, and then Soyabean oil (as oil phase), Tween 20 (as surfactant), and Span 80 (as co-surfactant) were selected for preparation of emulsion by titration method. Adsorption to solid carrier technique was used for solid SEDDS, areosil (Colloidal silica) used as adsorbent. In that formulation, I was having carbopol 934 and another formulation II HPMC K 4 M. The flow properties of all formulation were within the acceptable range; therefore, they can be easily filled into capsule. IR spectral and DSC thermograph analysis showed that there was chemical interaction between drug and polymer. In-vitro release studies were carried out in phosphate buffer pH 7.4. Release profile of pure drug formulation showed 38%, formulation I showed highest 54% cumulative drug release and formulation II showed lowest i.e. 14% drug release. Student’s t-test was determined for In-vitro drug release data for different polymeric formulations...

The objective of present study was to develop extended release microspheres of quetiapine fumarate using Eudragit RS 100 and Eudragit RL100 to reduce the dosing frequency. The quetiapine fumarate-loaded Eudragit microspheres were formulated by a solvent evaporation method. A 32 factorial design was employed to study the effect of concentration of sodium lauryl sulfate (SLS) and drug: polymer ratio on percentage yield, percentage entrapment efficiency, particle size, and % in-vitro drug release at 10 h. Drug excipients compatibility study by DSC showed no interaction between drug and excipients. The entrapment efficiency was found to be 40.56 ±1.32 % to 72.66 ±2.13 %, and the particle size range was 165±3.51 µm to 243±3.05 µm. In-vitro drug release of quetiapine fumarate microspheres showed a sustained release up to 24 h. Concentration of SLS and drug: polymer ratio had significant effect on % yield, % entrapment efficiency, particle size and % in-vitro drug release. From all parameters and experimental design evaluation it was concluded that drug release rate decreased with an increase...

Dexibuprofen is a Non-Steroidal Anti-Inflammatory Drug. It indicated short-term management of mild to moderately severe acute pain, dental pain, dysmenorrhoea, muscular pain and osteoarthritis. In the prevailing work, studies have been carried out on the preparation and in-vitro characterization of matrix tablets of dexibuprofen using different polymers like hydrophilic and hydrophobic. Different formulations had been prepared by wet granulation method using various release retarding polymers like methylcellulose, xanthan gum, and sodium carboxymethyl cellulose. Water-soluble surfactant sodium lauryl sulfate was employed to enhance the solubility of the dexibuprofen. Drug-excipients compatibility became performed by way of FTIR. Different parameters were evaluated for hardness, thickness, friability, drug content material, and in-vitro drug release. The excellent consequences were determined in terms of physicochemical parameters. The 10 numbers of formulations have been discovered to display the highest drug release of the drug. Mathematical analysis of the release kinetics has been accomplished to determine the mechanism of drug release. In-vitro release records have been fitted into diverse models to envision the kinetic of drug...

Heavy metal toxicity has been a subject of concern for the past few decades. Due to the emerging awareness about the detrimental health hazards and adverse effects across all the levels of any ecosystem, the removal of heavy metals (HM) from contaminated water systems and soil has gained the profound attention of the scientific community for the last couple of decades. Living and dead cells of biological organisms have found to have capable of retaining the harmful HMs substantially from aqueous and solid matrix. This review encompasses the efficacy of cyan bacterial cells in removing HMs from contaminated water and wastewaters. The different strains collected from different sources which are capable of removing specific species have been discussed along with the biotic and biotic factors affecting the process have been assessed. Also, the mechanism of toxicity and removal of HMs through biosorption and bioaccumulation by these cells have been taken into consideration. The thorough knowledge of the cyanobacterial removal of HMs can be a solution towards sustainable, cost-effective green...

Objective: Rheumatoid arthritis (RA) is a systemic disorder which involves the activation of immune system against the self-tissues. The main targets of this disease are the joints. Being systemic, the development of this disease involves different mechanisms, and thus, the exact cause of this disease remains unknown. Although different drugs have been developed, none has been found to be the cure for this disease. The present study was commenced to evaluate the in-vivo anti-arthritic effect of polyherbal formulation of selected plants Polygonum glabrum, Canthium dicoccum, Ochna obtusata and Argyreia nervosa. Materials and Methods: In-vivo anti-arthritic activity of the ethanolic extract of different portions capsule formulation F4 investigated orally was assessed using complete Freund’s adjuvant-induced arthritis. Results: In complete Freund’s adjuvant-induced arthritis models, the polyherbal extract formulations significantly (P < 0.001) reduced joint and paw swelling and markedly improved body weight, hematology profile, and parameters in complete Freund’s adjuvant model. Conclusion: It could be concluded that the ethanolic extract of two different formulations holds anti-arthritic potential, supporting its traditional use...
