Abstract

The aim of this study was to optimize the use of Ca-Alginates beads as a drug reservoir in the patch system with and without freeze-drying process. Meloxicam, an anti-inflammatory non-steroidal drug, was used as a drug model. Ca-alginate beads were prepared by ionic gelation method using polymer alginate and cross-linker CaCl2. The beads were evaluated for its melting temperature, FTIR spectra, and entrapment efficiency. The FTIR study showed the loss of guluronic peaks of alginate caused by a cross-linking process with Ca2+, characteristics peaks of meloxicam still appeared indicating the compatibility of the drug with the polymers used. The using Ca-alginate beads without freeze-drying process as a drug reservoir resulted in a very wet patch that was difficult to dry, cracked surface, and pharmaceutically not acceptable. Meanwhile, patch using Ca-alginate beads with the freeze-drying process as a drug reservoir demonstrated satisfactory characteristics with minimum weight variation among the patches that lead to giving uniformity in the drug content.

Abstract

This research formulate erythropoietin-alginate microspheres and to evaluate characteristics of erythropoietin-alginate microspheres at different amount of drug using aerosolization. Amount of erythropoietin are 10.000 IU (F1); 20.000 IU (F2); 60.000 IU (F3). The mixture of erythropoietin-alginate was sprayed into CaCl2 and was stirred at 1000 rpm for 30 minutes. Formulas resulted spherical shape of microspheres. The size of microspheres was 2.77 µm for F1; 3.89 µm for F2; and 4.42 µm for F3. The results of swelling index showed that swelling index of microspheres increased by increasing the concentration of erythropoietin. The results were in accordance with the size of the microspheres that increased with increasing concentration of drug. The yields of microspheres obtained were respectively 91.92%; 87.53%; 86.50% for F1, F2 and F3. It can be concluded that the particle size of microspheres, swelling index increased by increasing concentration of erythropoietin. In contrast, yield of microspheres decreased by increasing drug concentration. In conclusion, formula of microspheres were potential in terms of characteristics and may recommend for further in vivo study.

Abstract

The study was designed to investigate the optimation of preparation of transdermal patch sodium diclofenac matrix type. In this study, matrix-type base containing diclofenac sodium were prepared using polymeric combination of EC N-20  and PVP K-30 in different ratios ( 9:1 (Formula I); 8:2 (Formula II); 7:3 (Formula III)) and 6:4 (Formula IV). The moisture content was calculated as a difference between initial and final weight with respect to final weight. The homogeneity of patch surface was determined using Scanning Electron Microscope (SEM) Released test using dissolution tester were carried out in 500 mL of  phosphate buffer salin pH 7.4 ± 0.05 at temperature 37 ± 0.5°C with speed of swirl 50 rpm. The concentration of sodium diclofenac released was determined using spectrophotometric method at l 276 nm. Data was analyzed by statistic programmed of SPSS using one way analysis of variance with degree of believed 95% (α = 0.05).  It is concluded that the polymeric combination EC N-20 and PVP K-30 in composition 7:3 (Formula III) was the best formulation.

Abstract

The use of microspheres nowadays is important in the pharmaceuticals formulation. The aim of the present research was to evaluate physical characteristics of ovalbumin-loaded alginate microspheres using aerosolisation technique at various concentrations of alginate and BaCl2. Alginate microspheres were characterized in terms of encapsulation efficiency, yield, particle size, surface morphology and protein integrity. The comparative study between concentrations of BaCl2 and alginate polymer was investigated. Increasing concentration of alginate polymer from 2.5 to 3.5% reduced their particle size and formed smoother and spherical microspheres. Increasing Ba2+ concentration, simultaneous increased the encapsulation efficiency and yield. Scanning electron microscope (SEM) photomicrographs revealed that with the increase in the electrolyte concentration the density of the cross link is also increased. Smoother surface was demonstrated when the electrolyte concentration is increased from 0.5M to 0.75M. Formula prepared using 0.75M BaCl2 and 3.5% alginate polymer resulted the highest encapsulation efficiency (92%), the highest microspheres yield (73%) and the smallest microspheres size (3.73µm). Most of the formulations maintain the integrity of ovalbumin after 2 hours incubation in pH 1.2 followed by 8 hours incubation in pH 7.4. The different formulations produced different physical characteristics of ovalbumin-loaded alginate microspheres.

Abstract

Antibiotics are not only used for humans, but also often used for cattle and livestock which are then been consumed by humans. This over prescribed and missed used of antibiotic is a major factor in antibiotic resistance. Antibiotic resistance is a condition where bacteria are unable to be treated with antibiotics. In fact, the use of antibiotics is the first response in curing infectious diseases (by bacteria) and preventing infectious diseases spreading. With antibiotic resistance, preventing infectious diseases by bacteria became harder. This community service activity came up with a slogan "Antibiotic Resistence Awareness Movement" was carried out in Surabaya 10 Public High Schools and Surabaya 17 Public High Schools with 60 students per school using several methods, namely: (a) giving lecture material using LCD projectors ) the implementation of poster making competitions, and (c) poster presentations that have been made that are accompanied by question and answer, and (d) evaluation activities in the form of written tests covering pre-test and post-test. Concerning the results of posters results, poster presentations and improving the results of this posttest can be concluded as a result of an increase in understanding and or knowledge of students of SMA 10 and SMA 17 Surabaya
