Abstract

The main objective of this research is to investigate the use of fly ash and other is Stone dust as partial replacement of cement and concrete production. In this research we analyze the strength of concrete made with using these waste materials one is Fly ash and other is Stone dust. The Fly as his used as 20 replace by weight of cement and Stone Dust as the partial replacement of Fine Aggregate from 0 , 10 , 20 , 30 and 40 . The grade of the concrete here is M 30 grade.

Abstract

Periodontal disease is chronic, highly prevalent infectious disease that requires prolonged and controlled delivery of antimicrobial agents into pockets. To achieve this objective, dual antimicrobials encapsulated chitosan fortified calcium alginate (CS-Ca-SA) microspheres were formulated by application of Plackett-Burman factorial design. The microspheres were optimized for particle size (PS), entrapment efficiency (EE) and drug release. The optimized microspheres presented average PS of 74-461 µm and EE of 62.45-86.20% with controlled drug delivery for 120 hours. FTIR disclosed successful complexation between SA and CS. DSC and XRD studies showed changes in the crystallinity of drugs in microspheres. Shape factor and SEM demonstrated spherical to pear-shaped microspheres. Release exponent >0.43 and high diffusion coefficients revealed non-Fickian-based diffusion-limited drug release. CS-Ca-SA microspheres exhibited surface pH of 6.5 ± 0.5, moderate swelling, less erosion and improved mucoadhesion over Ca-SA microspheres. Also, significant antimicrobial activity against Escherichia coli and Staphylococcus aureus and cytocompatibility with L929 cell lines were observed. Further, microspheres exhibited long-term stability on refrigeration. The outcomes of study supported the potential of dual polymer and dual drug-based biodegradable, stable, non-toxic, mucoadhesive, controlled and prolonged drug release microspheres as more patient compliant by administration into periodontal pockets for the management of periodontal disease.

Abstract

Atorvastatin calcium (ATR), a second generation statin drug, was encapsulated in eudragit RSPO-based polymeric nanoparticles. The effect of independent variables (polymer content, stabilizer concentration, volume of chloroform and homogenization speed) on response variables (mean diameter particle size and entrapment efficiency) were investigated by employing central composite experimental design. All the independent variables were found to be significant for determining the response variables. Solid-state characterization study indicated the absence of physicochemical interaction between drug and polymer in formulation. Morphological study exhibited homogenous spherical shape of formulated nanoparticles.In vitrorelease study in phosphate buffer (pH 7.4) demonstrated sustained release profile over 24 h. Pharmacokinetic study in Charles Foster rats showed significant enhancement in oral bioavailability as compared to pure drug suspension. Efficacy study (lipid profile and blood glucose level) significantly justified the effectiveness of formulation having 50% less dose of ATR as compared to pure drug suspension. The effectiveness of formulation was further justified with an improved plasma safety profile of treated rats. Hence, ATR encapsulated eudragit RSPO nanoparticles can serve as potential drug delivery approach to enhance drug bioavailability, efficacy and safety profiles to alter existing marketed drug products.

26. Advances in Patents Related to Intrapocket Technology for the Management of Periodontitis

Author

K. Yadav, Sarita, Khan, Gayasuddin, and Mishra, Brahmeshwar

Abstract

Increased prevalence of oral diseases such as gingivitis, periodontitis and dental caries has become major health issue worldwide. Such growing incidence of periodontitis has directly affected the development of drug delivery systems and growth of the market. Since the infections are limited to periodontal pockets or oral cavity, localized intrapocket drug delivery will be more beneficial than conventional systemic administration. Advances in intrapocket technology and innovations in the field of periodontal drug delivery led to increased patent applications. Newer trends like use of mucoadhesive polymers, in situ forming gels, viscosity modifiers, plasticizers etc which can enhance intrapocket retention of drugs have gained considerable attention among researchers and industrialists. Current market is flooded with products such as Periostat, Periochip®, Atridox®, Arestin®, Actisite®, Dentomycin®, and Elyzol® and generics such as metronidazole, levofloxacin, tetracycline, doxycyline and minocycline for intrapocket delivery. There is a need of novel drugs and delivery systems with better efficacy profiles than the existing compounds. Inclusion of novel technologies like films, fibers, in situ forming implants, microparticles, nanoparticles, and liposomes as intrapocket drug delivery has great potential. Development of antibiotic free drug delivery such as antiseptics, host modulators, biofilms inhibitors and antibodies has promising role in the improvement of pathogenesis of periodontitis. Further, this review deals with various innovations in drug delivery and patents related to localized intrapocket administration of medicaments in the implications of periodontitis.
