Abstract

Tablet vaginal adalah tablet yang dirancang untuk administrasi vagina dalam pengobatan infeksi lokal, penyerapan sistemik, dan penyerapan ke dalam jaringan vagina. Jumlah pengisi memiliki konsentrasi terbesar dibandingkan jumlah eksipien yang lain, sehinggga pengisi memiliki peran penting dalam membentuk karakteristik tablet yang bagus serta diharapkan mampu melepaskan zat aktif dengan baik. Sebagai bahan pengisi, starch 1500 memiliki sifat kompresibilitas yang sangat baik sehingga cocok digunakan sebagai metode kempa langsung, tetapi starch 1500 memiliki sifat alir yang tidak bagus yang  berpengaruh pada proses pencetakan tablet, sehingga untuk memperbaiki sifat alir dari starch 1500 dibutuhkan penambahan glidan. Tujuan dari penelitian ini adalah membandingkan glidan talc-colloidal sillicon dioxide dengan colloidal sillicon dioxide dalam memperbaiki sifat alir sehingga menghasilkan karakteristik fisik dan daya adhesi yang baik serta optimum pada tablet vaginal metronidazole. Hasil uji menunjukkan bahwa formula 2 (F2) yaitu glidan colloidal sillicon dioxide memberikan karakteristik fisik yang lebih bagus meliputi kekerasan, kerapuhan, disintegrasi, keseragaman bobot, dan keseragaman kandungan daripada formula 1 (F1) yaitu glidan talk. Untuk uji disolusi dari kedua formula tidak memenuhi spesifikasi karena hasilnya dibawah 85 %. Daya adhesi F2 juga lebih kuat yaitu mampu menahan pemberat hingga 5,16 kg sedangkan F1 hanya mampu menahan pemberat hingga 4,33 kg. Penelitian ini menyimpulkan bahwa F2 memiliki karakteristik fisik dan daya adhesi tablet yang lebih baik dibandingkan dengan F1. Kata kunci: Colloidal sillicon dioxide, Daya adhesi tablet vaginal, Karakteristik fisik, Talc.

Abstract

Penuaan adalah suatu proses biologis kompleks sebagai hasil dari penuaan intrinsik (dari dalam tubuh seperti genetik) dan penuaan ekstrinsik (dari lingkungan). Faktor yang paling berpengaruh pada penuaan adalah radikal bebas karena dapat menyebabkan stres oksidatif yang berperan penting dalam proses penuaan. Penggunaan antioksidan dari buah-buahan salah satunya stroberi, menjadi suatu faktor penting untuk melawan penuaan akibat radikal bebas. Antosianin di dalam stroberi memiliki efek antioksidan paling tinggi untuk melawan radikal bebas. Antioksidan tersebut digunakan dalam produk kosmetik untuk memaksimalkan perawatan terhadap penuaan. Penelitian ini bertujuan untuk mengoptimasi formula sediaan krim ekstrak stroberi dengan membandingkan penggunaan jenis emulgator nonionik dan anionik. Ekstrak stroberi didapatkan dengan mengektraksi stroberi menggunakan pelarut metanol, aquades, dan asam format. Ekstrak diformulasikan ke dalam krim yang dibagi menjadi dua formula yaitu formula A yang menggunakan emulgator nonionik (tween 80 dan span 80) dan formula B yang menggunakan emulgator anionik (sodium oleate dan trietanolamin). Penentuan stabilitas dan formula yang optimum didapatkan dari evaluasi sediaan krim yang meliputi uji organoleptis, uji homogenitas fisik, uji pH, uji daya sebar, uji daya lekat, dan uji stabilitas suhu. Hasil penelitian menujukkan bahwa penggunaan emulgator baik nonionik dan anionik dapat menghasilkan sediaan krim yang baik, tetapi formula B lebih menunjukkan konsistensi sediaan krim yang lebih baik dibandingkan formula A. Kesimpulan dari penelitian ini adalah emulgator jenis anionik lebih sesuai untuk formula sediaan krim ekstrak stroberi (Fragaria x ananassa). Kata kunci: Ekstrak stroberi, Jenis emulgator, Stabilitas sediaan krim.

Abstract

Solubility is prerequisite for drug absorption across absorptive cell lining the small intestine. It is a problem for poor water soluble drug because limiting its bioavailability when administered by oral route. Lipid based delivery system such as self-nanoemulsifying delivery system (SNEDDS) can be utilized in improving its solubility so that better bioavailability is achieved. Pterostilbene has extremely low solubility in water then become its limiting factor for the bioavailability. This research developed SNEDDS for oral delivery of pterostilbene. Optimum composition of SNEDDS formulation was judged by its dispersion efficiency and clarity when dispersed in water. The efficiency of this formula in enhancing bioavailability was assessed by in vitro digestion model to predict its bioavailability by determining its bioaccessibility. The result showed that optimum composition of SNEDDS was achieved by soybean oil-Croduret® 50-Span 80-PEG 400 in ratio of 16.37 %, 32.07 %, 11.56 %, and 40 %, respectively. This formula has bioacessibility of 91.48 ± 2.18 %, and it is much higher compared to pterostilbene that was not formulated into SNEDDS, i.e 4.63 ± 1.11 %. Determined by dynamic light scattering, this optimum formula has droplet size of 31.8 nm when dispersed in water.

Abstract

Inflammaging is a systemic inflammation caused by the aging process without any infection from the outside and it is a very high factor affecting the morbidity and mortality in the elderly. Pterostilbene contained in blueberries can prevent inflammation and oxidation. However, pterostilben has low water solubility and stability, so that to improve stability and acceptability is by making Pterostilbene Transfersome. Transfersome consisted of phospholipid in the form of phosphatidylcholine as a forming component of vesicles, surfactants as Edge activators, which increased transfersome’s flexibility. The composition of lecithin as phospholipid and surfactant was variable that effecting the optimization of Transferome. This study aimed to determine the effect of the ratio between soy lecithin as phospholipid and sodium cholate as surfactants to particle size. Comparison used was soybean lecithin 94%: 6% sodium cholate (F1); 95% soybeans: 5% sodium cholate (F2); and soybean 96%: 4% sodium cholate (F3).

Abstract

This study aims to encapsulate Cosmos caudatus K. leaf extract in sodium alginate crosslinked with calcium chloride (CaCl2) as coating materials through freeze-drying. Antioxidant assays were performed to evaluate the applicability of the microcapsules as antidiabetic medicines. Their characteristics, antioxidant activity, and encapsulation efficiency (EE) were also examined. Results indicated that the concentration of sodium alginate and pH influenced the manufacturing process of the microcapsules. The highest EE was obtained at pH 6 and alginate concentration of 2% (w/v). The IC50 for the antioxidant activity of the microcapsules was 139.96 ± 1.094 μg/mL. Scanning electron microscopy confirmed the presence of irregular and spherical structures on the surface. Fourier transform infrared spectra showed new absorption bands at 1593.10 and 1427.59 cm−1, demexistening the existence of stretching vibrations of COO−. Absorption at 1024.14 cm−1 demonstrated C–C and C–O bond stretching vibrations in the sodium alginate–CaCl2 crosslinks. Fourier transform infrared spectrum analyses indicated that sodium alginate and CaCl2 formed chemical bonds, enabling microencapsulation. This study discovered that microencapsulation is a highly prospective and adaptable strategy for enhancing the medicinal use of plant extract.

Abstract

Aging of the skin due to exposure of UV rays is referred as photoaging.  Photoaging causes dry skin, wrinkles, darker skin pigmentation, and reduced skin firmness. The effect of photoaging can be treated by compounds that have antioxidant activity. Coffee contains polyphenols (caffeic acid and chlorogenic acid) which can inhibit the formation of ROS free radicals. This makes coffee an antioxidant potential in photoaging treatment. This study aims to determine the effectiveness of coffee extract as an antioxidant in photoaging treatment. The method used in this study is Systematic Literature Review. A comprehensive literature search was conducted using the Harzing's Publish or Perish application on several databases, such as Google Scholar, PubMed, Scopus, and Crossref using the keywords "coffee AND antioxidant AND ultraviolet AND photoaging". The article selection flow used the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) protocol. The total search results were 1202 articles, and there were 6 research articles that matched the inclusion and exclusion criteria that had been set. The results of this study concluded that coffee extract can be used as an antioxidant in photoaging treatment. The effectiveness of coffee extract as an antioxidant in photoaging treatment was demonstrated by reducing the expression of MMPs, increasing the expression of type 1 procollage, reducing the area of wrinkles, and reducing TEWL. Coffee leaf extract decreased the expression of MMPs (MMP-1 ¯ 50%, MMP-3 ¯ 10% to 60%, MMP-9 ¯ 30% to 50%) and increased type 1 procollagen 60%. Coffee bean extract decreased the expression of MMPs (MMP-1 ¯ 5% to 60%, MMP-2 ¯ 20% to 60%, MMP-3 ¯  30%, MMP-9 ¯ 20% to 70%, MMP-13 ¯ 30% to 45%), increased type 1 procollagen 10% to 60%, reduced wrinkle area 20% to 88%, and decreased TEWL 10% to 20%.
