Bromelain as an anti-inflammatory and anti-cancer compound

2019-05-06T09:32:56+00:00

Inflammation is a complicated problem for today’s human beings. Large numbers of people have been diagnosed with arthritis along with inflammation. This is beside the others that suffer inflammation caused by an injury. There are alternatives that can be considered as temporary or permanent treatments of chronic inflammatory diseases. Plants, as well as other biological resources, are most welcomed to the therapeutic area. Using the plants’ compounds with high potential as novel techniques are today’s bio-pharmacologist concern. Bromelain has been more attractive due to its characteristics. This review is an overview of anti-inflammatory and anti-cancer effect of bromelain as a confident treatment for all inflammatory disease.

The salivary biomarkers: future clinical investigation technique

2019-08-20T14:25:27+00:00

Human saliva is a clear, slightly acidic biological fluid containing a mixture of secretions from multiple salivary glands, including the parotid, sublingual gland other minor glands beneath the oral mucosa as well as gingival crevice fluid. Salivary diagnostics has evolved into a sophisticated science and serves as a subset of the larger field of molecular diagnostics, now recognized as a central player in a wide variety of biomedical basic and clinical areas. Saliva biomarkers are source of indicators for local, systemic, and infectious disorders. The saliva based microbial, immunologic, and molecular biomarkers offers unique opportunities to bypass the painful invasive procedures such as biopsies and repeated blood draws by utilizing oral fluids to evaluate the condition of diseased individuals. Accurate and reliable early stage disease detection is the benefit of salivary biomarkers. Salivary biomarkers represent a promising non-invasive approach for oral cancer detection also. This review explains about the salivary biomarkers and their diagnostic approaches

Osmotic drug delivery system of valsartan

The objective of this study is to design and evaluate a new EOP called swellable elementary osmotic pump (SEOP) of the freely water soluble drug, amitriptyline hydrochloride (1 g /mL) by adding water swellable polymers in the core. The hydrophilic polymers included in the core retard the highly water soluble drug by producing hydrogel within the core, which may restrict and delay the solvent contact with drug molecules and may increase the diffusional length of the solvent to achieve a constant release rate. Thus, this technology can be exploited to achieve constant drug release at predetermined rate especially for highly water soluble drugs.

Formulation and invitro evaluation of oral extended release microspheres of aceclofenac using various natural polymers

2019-05-04T20:42:00+00:00

In the present work, bioadhesive microspheres of Aceclofenac using Sodium alginate along with Carbopol 934, Carbopol 971, HPMC K4M as copolymers were formulated to deliver Aceclofenac via oral route. The results of this investigation indicate that ionic cross-linking technique Ionotropic gelation method can be successfully employed to fabricate Aceclofenac microspheres. The technique provides characteristic advantage over conventional microsphere method, which involves an “all-aqueous” system, avoids residual solvents in microspheres. FT-IR spectra of the physical mixture revealed that the drug is compatible with the polymers and copolymers used. Micromeritic studies revealed that the mean particle size of the prepared microspheres was in the size range of 512-903µm and are suitable for bioadhesive microspheres for oral administration. The in-vitro mucoadhesive study demonstrated that microspheres of Aceclofenac using sodium alginate along with Carbopol934 as copolymer adhered to the mucus to a greater extent than the microspheres of Aceclofenac using sodium alginate along with Carbopol 971 and HPMC K4M as copolymers. The invitro drug release decreased with increase in the polymer and copolymer concentration. Analysis of drug release mechanism showed that the drug release from the formulations followed non-Fickian diffusion and the best fit model was found to be Korsmeyer-Peppas. Based on the results of evaluation tests formulation coded T4 was concluded as best formulation.
