Abstract

Ibuprofen is a part of Non Steroid Anti-Inflamatory Drug (NSAID) that used as treatment of pain or inflammatory. Solid dispersion method may improve the solubility of ibuprofen. Ibuprofen was made into a gel product to overcome the side effect. Addition of an enhancer in a gel may increase the penetration of an active substance. The purpose of this study is to understand the effect of tween 80 and ethanol as an enhancer to penetration and drug release of ibuprofen in gel, the effect to physical quality of gel, and to obtain the optimum formula of the combination of enhancer. This study used simplex lattice design with two factor which is tween 80 and ethanol in gel product formula 1; formula 2; and formula 3 in sequence 100%:0%; 50%:50%; 0%:100%. Solid dispersion of ibuprofen-PEG 6000 was made with melting method and tested with FT-IR before made into gel product. Penetration test is done by using Franz diffusion cell with selofan membrane and the determination of the optimum formula obtained based on counterplot from optimization with design expert 10.0.01 trial version with the parameters of the critical level is viscosity and penetration substanced. The results showed the combination of tween 80 and ethanol could affect viscosity and penetration of active substance, tween 80 had a greater effect than ethanol. The proportion of tween 80 4.681% and ethanol 16.319% produces the optimum formula with the most optimum viscosity, adhesion, and drug penetration

Abstract

Curcumin, a natural compound with potent antioxidant properties, faces challenges in pharmaceutical use due to its poor water solubility and low bioavailability. To overcome these limitations, curcumin was encapsulated in a transfersome drug delivery system and subsequently incorporated into a gel to enhance topical delivery and improve drug release efficiency. This study aimed to evaluate the influence of phospholipid, Tween 80, and cholesterol ratios on the physicochemical properties of curcumin-loaded transfersomes and to assess the antioxidant activity of the optimized transfersome gel. A Simplex Lattice Design (SLD) using Design Expert software generated 14 formulations varying in the three components. Transfersomes were produced via the thin layer hydration method and analyzed for particle size, zeta potential, and entrapment efficiency (%EE). The resulting gel was characterized for pH, viscosity, spreadability, adhesiveness, diffusion behavior using Franz cells, and antioxidant activity through the DPPH assay. Statistical analyses employed ANOVA, Wilcoxon, and T-tests. The optimized formulation containing 700 mg phospholipid, 200 mg Tween 80, and 50 mg cholesterol yielded particles of 134.627 nm, zeta potential –8.924 mV, and 93.656% EE. Antioxidant evaluation showed IC₅₀ values of 24±1.78 ppm (transfersome) and 42±2.5 ppm (gel), both indicating very strong antioxidant activity. The gel released 23.12 µg/cm² curcumin within 150 minutes.

Abstract

Antioxidants are substances needed by the body to neutralize free radicals and prevent damage caused by free radicals. Moringa leaves contain flavanoids, alkaloids, saponins and tannins that are antioxidants because of their ability to capture free radicals. This study aims to determine the effect of moringa leaf fractions on spatial memory ability using the Radial Arm Maze method, a decrease in malondialdehyde levels and inhibition of damage to the number of hippocampal pyramidal cells in CA1 & CA3 areas. Moringa leaves were extracted using the maceration method with 70% ethanol solvent. Then the ethanol extract of Moringa leaves was fractionated using the liquid-liquid method with n-hexane, ethyl acetate and water as solvents. Next, the mice were subjected to induction treatment with lead acetate, then observed for 21 days with the Radial Arm Maze, then the mice underwent surgery and their brains were removed for MDA level testing and histopathological observation. Data were analyzed statistically using one-way ANOVA (p<0.05) followed by Tukey's test. Based on the results obtained, the ethyl acetate fraction, n-hexane fraction and water fraction can influence the improvement of spatial memory by reducing latency time and type B errors, reducing malondialdehyde levels with TBARS and inhibiting damage to CA1 and CA3 hippocampal pyramidal cells which are characterized by pknotic neuron nuclei (shriveled), dark, solid, and vacuolized.

Abstract

Jasmine leaves (Jasminum sambac L.) are known to contain phenolic and flavonoid compounds with antioxidant potential. This study evaluated the antioxidant activities of the ethanol extract, solvent fractions, and subfractions of jasmine leaves. It characterized the chemical profile of the most active subfraction using gas chromatography–mass spectrometry (GC–MS). Jasmine leaves were extracted by maceration using 96% ethanol and subsequently fractionated with n-hexane, ethyl acetate, and water. The ethyl acetate fraction, which exhibited the strongest antioxidant activity, was further separated by vacuum liquid chromatography to obtain subfractions. Antioxidant activity was determined using the DPPH method and expressed as IC₅₀ values. The most active subfraction was analyzed by GC–MS. The results showed that the ethyl acetate fraction had the lowest IC₅₀ among the solvent fractions, while subfraction 1 (SF1) exhibited the strongest antioxidant activity, with an IC₅₀ of 49.78 ppm, indicating strong activity. GC–MS analysis of the most active subfraction suggested the presence of antioxidant-related compound classes with tentative identification. These findings demonstrate that subfractionation enhances antioxidant activity and enriches antioxidant-related constituents in jasmine leaves, while highlighting the need for advanced analytical techniques to confirm compound identities.

Abstract

Paracetamol or acetaminophen is a widely used analgesic-antipyretic drug worldwide. Paracetamol in liquid form is preferred because of its easy administration and rapid absorption in the body and large doses are easily adjusted for children. Storage of paracetamol syrup in accordance with the etiquette is at controlled room temperature. Beyond use date (BUD) is the time limit for the use of a drug after it has been formulated, prepared or after its primary packaging has been opened or tampered with. The purpose of this study was to determine the effect of storage temperature on paracetamol syrup levels during BUD. Paracetamol syrup was stored in a room with air conditioning (20-25oC) and without air conditioning (30-40oC) for 14 days. Observation of levels was carried out on days 0, 3, 7, 10 and 14 using UV-Vis spectrophotometry with a wavelength of 247 nm and operating time for 22 minutes. The results of the determination of paracetamol syrup levels after storage for 14 days in a room with air conditioning in generic and trademark samples were 90.05 ± 1.34% and 92.73 ± 1.01%, respectively. Paracetamol syrup levels in a room without air conditioning in generic and trademark samples are 79.07 ± 0.99% and 81.10 ± 2.02%. Storage temperature affects paracetamol syrup levels during storage with a difference in levels of 10.98% for generic samples and 11.63% for trademark samples during BUD.   ABSTRAK Parasetamol merupakan obat analgesik-antipiretik yang banyak digunakan di seluruh dunia. Parasetamol dalam bentuk cairan lebih disukai karena pemberiannya yang mudah dan cepat terabsorpsi dalam tubuh serta dalam pemberian dosis besar mudah disesuaikan untuk anak. Penyimpanan parasetamol sirup yang sesuai dengan etiket adalah pada suhu ruang terkendali. Beyond use date (BUD) adalah batas waktu penggunaan obat setelah diracik, disiapkan atau setelah kemasan primernya dibuka atau dirusak. Tujuan penelitian ini adalah untuk mengetahui pengaruh suhu penyimpanan terhadap kadar parasetamol sirup selama BUD. Parasetamol sirup disimpan pada ruang dengan penyejuk udara (20 – 25oC) dan tanpa penyejuk udara (30 – 40oC) selama 14 hari. Pengamatan kadar dilakukan pada hari ke-0, 3, 7, 10 dan 14 menggunakan spektrofotometri UV-Vis dengan panjang gelombang 247 nm dan waktu operasi selama 22 menit. Hasil penetapan kadar parasetamol sirup setelah penyimpanan selama 14 hari di ruang dengan penyejuk udara pada merek generik dan merek dagang berturut-turut yaitu 90,05 ± 1,34% dan 92,73 ± 1,01%. Kadar parasetamol sirup diruang tanpa penyejuk udara pada merek generik dan merek dagang yaitu 79,07 ± 0,99% dan 81,10 ± 2,02%. Suhu penyimpanan mempengaruhi kadar parasetamol sirup selama penyimpanan dengan selisih kadar 10,98% untuk merek generik dan 11,63% untuk merek dagang selama BUD.
