Abstract

Background: Chronic plantar ulcers in leprosy (CPUL) increase morbidity, increase medical costs, cause loss of productivity, and decrease quality of life. CPUL is a severe complication of leprosy disease with a 10-20% incidence. In general, CPUL consume a significant amount of time to heal. Green tea extract contains high amount of Epigallocatechin gallate (EGCG). EGCG functions as antiinflammatory, antimicrobial, and immunomodulator. This suggests that EGCG is effective for dermal wound treatment by facilitating reepithelialization. Purpose: To investigate the effect of topical EGCG 1% on the CPUL healing process. Methods: The topical EGCG 1% were applied every three days for eight weeks. Size of the ulcers, side effects and possible complications were monitored weekly. Result: There were significant clinical and statistical differences in the size and depth of the ulcers (p=0.000), as observed in the EGCG group. There was no side effect and complication found. Conclusions: Topical EGCG 1% was effective for CPUL healing. Sixty three point six percent of the ulcers were clinically healed, 31.8% demonstrated improvement, and 4.6% no effect was observed.

Abstract

Staphylococcus aureus is one type of bacterium that causes skin infections resistant to some antibiotics. This encourages research to find new antibacterials by using substances from natural sources, often called medicinal plants. Aqueous extract of Roselle (Hibiscus sabdariffa L.) flower (AERF) was selected as one of natural ingredients for antibacterial in gel dosage form, in which sodium alginate was used as a matrix base. In this study, determination of the sodium alginate concentration effects (2.5%, 3% and 3.5%) on the properties of the gel was performed. The characteristics evaluated included pH, viscosity, and dispersive power; that should be met standard requirement and the gel ability to inhibit Staphylococcus aureus ATCC 25923 growths.  A diffusion test method was used to determine the Minimum Inhibitory Concentration (MIC) of the AERF powder against the test bacteria. The study results showed that AERF gel preparation with a composition of 3% sodium alginate and 3% roselle extract had better properties (pH, viscosity, and dispersive power) than the matrix and extract concentrations of 2.5% and 3.5% respectively. It was found that the optimum formula obtained a MIC of 0.04 mg/ml. In line with these results, it is expected that the AERF gel preparation will be stable, safe, and acceptable when used and might be recommended as antibacterial topical dosage form against Staphylococcus aureus. In the future, inhibitory activity against resistant pathogenic bacteria could be evaluated and developed.

Abstract

Coenzyme Q10 berfungsi sebagai antioksidan yang dapat melindungi tubuh dari kerusakan yang dikarenakan radikal bebas. Coenzyme Q10 tidak stabil dan mudah terdegradasi ketika terpapar cahaya sehingga perlu dipilih suatu sistem penghantaran yang dapat memperbaiki stabilitas serta dapat meningkatkan penetrasinya. Nanostructured Lipid Carier (NLC) merupakan salah satu metode untuk meningkatkan penetrasi obat melalui stratum corneum. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh HPMC 606 terhadap kadar Coenzyme Q10 yang terpenetrasi pada kulit tikus. Pada penelitian ini dibuat sediaan patch tipe membran menggunakan sistem NLC. Coenzyme Q10 sebagai drug reservoir, sedangkan HPMC 606 sebagai rate controlling membran dengan kadar 20%, 15%, dan 10%. Uji penetrasi Coenzyme Q10 dari sediaan patch secara in vivo dengan menggunakan kulit tikus Wistar. Semakin kecil kadar HPMC 606 yang digunakan (20%, 15%, 10%) ternyata menghasilkan nilai fluks yang cenderung semakin besar (F1 = 15,714±0,257 %/jam ; F2 = 14,778±0,224 %/jam ; dan F3 = 13,765±0,182 %/jam) dan lag time yang semakin cepat (F1 = 0,523±0,029 jam ; F2 = 0,657±0,021 jam ; dan F3 = 0,679±0,016 jam). Dari hasil tersebut dapat disimpulkan bahwa semakin kecil HPMC 606 yang digunakan sebagai rate controlling membrane, maka semakin besar Coenzyme Q10 yang berpenetrasi, sehingga F1 terpilih sebagai formula yang paling baik.

Abstract

In drug release kinetics, the drug-matrix interaction is one of the important mechanisms to be dictated. Unfortunately, there is still minimum information discussing the effect of interaction between a drug and its matrix to the release profile of the drug. Therefore, there is an urgent need to conduct research related to the study of drug-matrix interaction. This paper reports the preparation of a drug delivery system (DDS) in the form of hard-shell capsules containing salicylamide (SCA) and analyses its drug-matrix interaction via dissolution test at different pH media and various release kinetics models. The matrix of hard-shell capsules was prepared from κ-carrageenan (CRG), crosslinked with maltodextrin (MD), and plasticized by sorbitol (SOR). The chemical properties of SCA were compared with paracetamol (PCT) using computational analysis to help to depict its drug-matrix interaction. The statistical analyses showed that SCA and PCT at pH 1.2, 4.5, and 6.8 had all different release profiles. Based on the goodness of fit evaluation, the diffusion mechanism of SCA at pH 1.2 and 4.5 could be best described by the Peppas-Sahlin model while the zeroth-order model fitted the dissolution profile at pH 6.8. In summary, it was proven that a different drug-matrix interaction produced a different dissolution profile.

Abstract

The solubility and partition coefficient are essential physicochemical parameters in developing a pharmaceutical dosage form of medicine. In addition, these parameters help to predict the absorption of an active compound in oral or topical dosage forms. Salicylamide, an active ingredient available in oral and topical dosage forms, is a weak acid (pKa 8.2) and is sparingly soluble in water. Meanwhile, its solubility and partition coefficients are influenced by the pH of the environment. The Henderson-Hasselbalch equation is used to predict solubility-pH and partition-pH profiles at various pH solutions. This study aims to determine salicylamide's solubility and partition coefficient in various pH (2–11). Both tests were carried out in various pH buffer solutions (at a concentration of 0.02 M and 0.2 ionic strength) in a water bath shaker at a temperature of 37 ± 0.5 °C. In addition, the salicylamide content was determined using the UV spectrophotometer method at the maximum wavelength at each pH. The results showed that the solubility increased at pH 2–10, while the partition coefficient value decreased. On the other hand, at pH 11, there was an increase in the number of ionized species, but the solubility decreased.

Abstract

Halal hard shell capsules are importantly needed by Indonesian consumers, who are predominantly Muslim, to substitute mostly used and commercially available products made from non-halal ingredients such as gelatin. The objective of this study is to prepare, characterize, and evaluate halal hard shell capsules made from k-carrageenan-xanthan gum with sorbitol as the plasticizer with diclofenac sodium as the model drug. Hardshell capsules were prepared with combinations of κ-carrageenan-xanthan gum at a weight ratio of 4:2 with the addition of 70% sorbitol, which added at a varied volume of 0.25; 0.50; 0.75; and 1.00 mL. Characterization of halal hard shell capsules includes swelling degree, tensile strength, Fourier Transformed Infrared (FTIR) and Scanning Electron Microscope (SEM), as well as disintegration test. The diclofenac sodium profile release was evaluated through the dissolution test at pH 6.8. The best physical characteristics were obtained by preparing capsule shells with a mixture of carrageenan-xanthan gum at a weight ratio of 4:2 with the addition of 0.25 mL sorbitol. The evaluation of Halal hard shell capsules showed that it had a swelling rate of 3.46% in water media, stress modulus of 28.6 MPa, strain modulus of 4.3 MPa, and modulus young of 362,3%, as well as disintegration time of capsules, was 51.8 minutes at pH 6.8. The dissolution test showed that diclofenac sodium was released at a level of 2.7% for 16 minutes. Based on this data, it can be concluded that the Halal hard shell capsule of κ-carrageenan-xanthan gum with the addition of sorbitol can be used as an alternative for the gelatin capsule with more controlled release.

Abstract

Kesehatan merupakan hal yang penting bagi setiap manusia. Salah satu upaya peningkatan kesehatan masyarakat adalah melalui pemberian kesadaran tentang pemahaman masyarakat terhadap obat yaitu cara mendapatkan, menggunakan, menyimpan, dan membuang obat (DAGUSIBU). Surabaya merupakan kota besar dengan penduduk yang banyak sehingga diperlukan suatu cara yang tepat untuk pemahaman DAGUSIBU. Pemberdayaan kader PKK Kota Surabaya dan kader PKK kecamatan merupakan aset yang sangat berperan dalam keberhasilan pengabdian kepada masyarakat. Tujuan pendampingan penyuluhan ini adalah untuk mengefektifkan pemahaman masyarakat tentang DAGUSIBU di wilayah Surabaya. Pelaksanaan penyuluhan DAGUSIBU dilakukan secara berjenjang melalui PKK Kota Surabaya. Pendampingan penyuluhan dimulai dari kader PKK Kota Surabaya di Kantor PKK Kota Surabaya, kemudian kader PKK Kota Surabaya meneruskan ke kader di kecamatan masing-masing. Metode penyuluhan ini menggunakan metode ABCD sebab sebelum penyuluhan masyarakat sudah memahami tentang DAGUSIBU. Hal ini terbukti pada saat pre-test yaitu PKK Kota Surabaya pemahamannya sebesar 62,39%, PKK Kecamatan Rungkut 75%, dan Kecamatan Pabean Cantian 68,75%. Berdasarkan hasil post-test peserta penyuluhan, didapatkan hasil post-test penyuluhan kader PKK di Kecamatan Rungkut dan Pabean Cantian lebih bagus dibandingkan dengan yang di PKK Kota Surabaya. Peningkatan pemahaman di PKK Kota Surabaya setelah penyuluhan adalah 88,70% sedangkan kader PKK Kecamatan Rungkut 90,91% dan Kecamatan Pabean Cantian adalah 93%. Hal ini menunjukkan bahwa dengan penyuluhan yang berjenjang dapat meningkatkan pemahaman masyarakat tentang DAGUSIBU. Metode pendampingan pemahaman DAGUSIBU secara berjenjang menunjukkan hasil peningkatan yang baik sehingga metode ini dapat diterapkan di kota-kota besar lainnya yang ada di Indonesia.

Abstract

Background: Lactobacillus plantarum is one of the lactic acid bacteria (LAB) with strong antibacterial activity. However, these bacteria show different growth for each strain. The turbidimetric bacterial growth curve approach is the most accurate, fastest, and most reproducible method for obtaining an overview of the bacterial life cycle. In addition, we also examined the antibacterial activity of each observation of the growth curve. Objective: The aim of the study was to determine the optimal incubation time with the highest biomass concentration and antibacterial activity of the Lactobacillus plantarum FNCC 0026. Method: Observations of optical density (OD) values "‹"‹were performed simultaneously on 10 points of Lactobacillus plantarum FNCC 0026 and performed every 12 hours. Antibacterial activity tested against Staphylococcus aureus ATCC 25923 and Escherichia coli ATCC 8739. Result: The Lactobacillus plantarum FNCC 0026 fermentation broth showed the highest OD value and antibacterial activity after 30 hours of incubation. The maximum diameter of the inhibition zone against Staphylococcus aureus ATCC 25923 and Escherichia coli 25923 were 17.08 ± 0.51 mm and 16.83 ± 0.54 mm. Conclusion: The results showed that the antibacterial activity had a linear relationship with the concentration of bacteria. In the Lactobacillus plantarum FNCC 0026, the optimum cultivation time is in the lag phase (24 – 30 hours).

Abstract

Background: For treatment or skin care via topical route, Coenzyme Q10 needs to permeate the epidermis which it is practically insoluble in water and a high molecular weight that make it difficult to penetrate the skin. Nanostructured Lipid Carriers (NLC) is chosen because of its ability to dissolve and solve the problem of low skin permeation. The type and ratio of solid and liquid lipids used in NLC affect the physicochemical characteristics, thus affecting the release profile and system stability. Objective: This study aimed to determine the effect of various ratios of Compritol 888 ATO as solid lipid and Miglyol 812 as liquid lipid on the physicochemical stability and Coenzyme Q10 release profile of NLC system. Methods: NLC was prepared using High Shear Homogenization method with three different lipid ratios. The ratio of Compritol 888 ATO : Miglyol 812 was 70:30, 80:20, and 90:10, respectively. NLC was evaluated for drug release and stability parameters including organoleptic, particle size, polydispersity index (PI), pH, viscosity, assay, and entrapment efficiency. Results: The stability test result for 90 days showed increments in the particle size and viscosity, whereas for assay and entrapment efficiency were decreased. The release test results showed no significant difference in the release parameters of the three tested formulas. Conclusion: During stability evaluation, NLC-CoQ10 systems did not significantly change pH and PI values, but statistically significantly changed particle size, viscosity, assay, and entrapment efficiency. The different in lipid ratios used in the formulas did not show significantly different results for release parameters.

Abstract

Background: Diclofenac potassium is an NSAID drug that is used in the treatment of mild to moderate pain. The use of this drug orally can cause side effects in the gastrointestinal tract, and the drug will undergo extensive first-pass metabolism in the liver. Therefore, preparations for transdermal patches were made. Objective: Determining the effect of the polymer ratios of carboxymethyl chitosan, polyvinyl pyrolidone K-30, and ethyl cellulose N22 on the physicochemical characteristics and drug release of a matrix type diclofenac potassium patch. Methods: In this study, matrix type diclofenac potassium patches were made using a combination of carboxymethyl chitosan (CMC), polyvinyl pyrrolidone (PVP) K-30 polymer, and ethyl cellulose (EC) N22 in a ratio of 2:3:7 and 3:2:7. Patches are made by mixing the entire polymer matrix and diclofenac potassium together, which are then evaporated and dried. Results: The results showed that the different polymer compositions of CMC, PVP K-30, and EC N22 resulted in patches with physicochemical characteristics that were not significantly different. The combination of these polymers is able to control the release of the drug from the patch for a long time. It was also found that increasing the concentration of CMC was able to increase the rate of release of diclofenac potassium. Formula 2 with a ratio of 3:2:7 is claimed to be the best formula in terms of physical, chemical, and drug release characteristics from the patch. Further studies are needed, such as drug penetration tests into the skin.
