Objective: Adapalene is a medicinal ingredient that can be used to treat acne. Adapalene has a Log P value of 8.6 and has high lipophilic and low solubility in water and is potentially degraded. Adapalene NLC can increase biphasic drug penetration at low doses but has good reactivity and provides occlusive properties that can increase skin hydration, thereby accelerating acne treatment. Methods: Forming Adapalene NLC using the method of heat homogenization followed by ultrasonication probe. The NLC formulas used were Precirol ATO5 ®4.0%, Myritol ® 2%, Cremophor RH 40 1%, Plantacare 1%, Tegocare 1%, and Adapalene 0.3%. Following that is the characterization of particle size, polydispersity index, zeta potential, efficiency entrapment. Results: The results showed the measurement of particle size with a range (150-318 nm), index polydispersion showed (0.12-0.36) and zeta potential (-26)-(-60 mV) and efficient entrapment testing showed results (84-98 %). In the TEM morphological evaluation of images showing spherical and evenly distributed forms, this is in line with the results of the adapalene NLC characterization. Conclusion: These results suggest that NLC containing adapalene showed excellent result.
ABSTRAK Dermatitis Atopik (DA) adalah penyakit inflamasi kulit kronis dan kambuhan, terutama pada anak-anak. Pengobatan DA salah satunya menggunakan hidrokortison. Sifat lipofil dari hidrokortison asetat (HA) akan berpengaruh terhadap penetrasinya kedalam kulit jika diberikan secara topikal. SLN (Solid Lipid Nanoparticle) merupakan sistem penghantaran obat baru yang terdiri dari matriks lipid padat dan surfaktan yang terdispersi dalam air dengan ukuran partikel 10-1000nm untuk meningkatkan solubility, stability, dan loading capacity. Metode: SLN dibuat dengan homogenisasi panas menggunakan magnetic stirrer selama 10 menit suhu 600C, dilanjutkan dengan ultraturax 5000rpm selama 10 menit dan ultrasonikasi dengan sonikator probe dengan amplitudo 55% selama 15 menit, mode pulse on-off 10 detik. Optimasi basis SLN dilakukan pada beberapa jenis lipid (GMS Cutina dan Apifil) dan surfaktan (Pluracare, Tegocare, Plantacare, dan Cremofor RH 40). Basis SLN yang terpilih adalah GMS Cutina sebagai lipid padat dengan kosentrasi 4%,5%, dan 6% dan surfaktan Pluracare 3% berdasarkan ukuran partikel terkecil, FTIR, dan DSC yang menunjukkan kompatibilitas dengan HA. Hasil: Formula SLN hidrokortison asetat yang digunakan adalah lipid padat GMS Cutina 4%-6% dan surfaktan Pluracare 3% menghasilkan ukuran partikel 806nm ± 124,67nm - 958nm ± 91,28nm, nilai PI masing-masing 0,874±0,07 - 0,943±0,15, dan nilai efisiensi penjerapan (EE) 12,5%, - 83,3%. Kata Kunci : Hidrokortison Asetat, Homogenisasi Panas, SLN (Solid Lipid Nanoparticle), Ultrasonikasi ABSTRACT Atopic dermatitis (DA) is a recurrent chronic inflammatory skin disease. Treatment of DA used one of them is hydrocortisone acetate. The lipophilic properties of hydrocortisone acetate (HA) will affect its penetration into the skin when administered topically. SLN (Solid Lipid Nanoparticle) is a new drug delivery system consisting of a solid lipid matrix and a water dispersed surfactant with a particle size of 10-1000nm to improve solubility, stability, and loading capacity. Method: SLN used hot homogenization using magnetic stirrer for 10 minutes temperature 600C, followed by ultraturax 5000rpm for 10 minutes and ultrasound with probe sonicator with 55% amplitude for 15 minutes, 10 second pulse on-off mode. Optimization of the SLN base was performed on several types of lipids (GMS Cutina and Apifil) and surfactants (Pluracare, Tegocare, Plantacare, and Cremofor RH 40). The preferred SLN base is GMS Cutina as a solid lipid with a concentration of 4%, 5%, and 6% and a 3% Pluracare as a surfactant based on the smallest particle size, FTIR, and DSC showing compatibility with HA. Result: The formula of SLN hydrocortisone acetate used GMS Cutina 4% -6% as a solid lipid and Pluracare 3% as a surfactant resulted a particle size of 806nm ± 124.67nm - 958nm ± 91.28nm, PI value of 0.874 ± 0.07 - 0.943 ± 0.15 , and the efficiency entrapment (EE) 12.5%, - 83.3%.

Mefenamic acid is a class of NSAIDs (Non-Steroid Antiinflammatory) which belongs to BCS group (Biopharmaceutical Classification System) class II that is low solubility with high penetration membrane. So it is necessary to increase the solubility to get absorption that can penetrate the maximum therapeutic zone of reagent. This study aims to determine the effect of the concentration of disintegran Croscarmellose sodium with a concentration of 1%-5% on the physical quality and dissolution rate because it has a working mechanism of water absorption (water wicking) and swelling rapidly. Raw material collection, manufacture of mefenamic acid tablets (the wet granulation method is used because it can improve the flow rate and the compressibility of the mefenamic acid), evaluation of mefenamic acid granules, evaluation of mefenamic acid tablets, data analysis using one way ANOVA. Characterization of physical quality of granules moisture content, flow rate, fixed angle according to requirements. Characterization of quality tablet hardness, friability, frixibility, weight, uniformity size, disintegration time, and dissolution according to requirements.. Statistical analysis, indicating that there are significant differences in hardness, weight, uniformity of size, crushed time, rate and dissolution. From the results of this study can be concluded that the formula with a concentration of Croscarmellose Sodium 5% gives the best results.
